Grinding pad polishing technology

The polishing pad floor is a kind of composite floor material with cement as the main raw material. Its low cost and good performance are widely used in large-area public buildings. According to statistics from relevant departments, the use of public buildings exceeds 6 billion square meters, hospitals, pharmaceuticals, machinery, government agencies, schools, commercial sites, airport terminals and other terminals.

Polishing pad ground defects are mainly

1) It is easy to weather and aging, and the life cycle is 2-5 years;

2) The surface is rough, the gap is large, the stain resistance is poor, and it cannot be cleaned after being contaminated;

3) Even if the original waxing and maintenance method is used to improve the surface finish, due to the complexity of the operation organization, the cost is huge, but the result is not satisfactory;
For the above reasons, it is generally believed that the polishing pad is a medium and low-grade floor decoration material.

The traditional polishing pad has the advantages of low cost, free coloring and easy construction, and has a huge market. The polishing pad used in various urban and rural buildings has more than 10 trillion square meters. However, the traditional construction technology caused the polishing pad to be very rough and filthy, and even dirty when it was not delivered, it also caused serious obstacles to daily hygiene.

However, as time went by, there were very prominent problems in actual use: weathering, abrasion, stains, and dullness. How to restore the weathered and abraded polishing pad to its original beauty is an increasingly urgent problem to be solved in the building decoration industry.

Grinding pad polishing technology

In the face of weathering and abrasion, the only method at home and abroad is to clean the surface of the stone and apply a layer of wax. This method can protect the new surface and delay the natural weathering and abrasion speed. However, for the weathered and abraded polishing pad surface, the effect is the same as the varnish on the surface of the decaying wood. It is impossible to reproduce a beautiful, mirror-like fruit. Moreover, the wax film thus formed has a poor durability, and it is only necessary to keep the wax on the left and right again. Not only is the construction frequent, but the cost is high. The cost of cleaning and waxing per square meter per year is as much as several hundred yuan. Cleaning and waxing is the only method that every cleaning company can’t cope with customers. It can neither cure the symptoms nor treat the root cause.

The reason why cleaning waxing is not the real stone floor treatment is that it does not really solve the technical key of polishing pad processing. The reason why the polishing pad is as bright as mirror and crystal clear is that the polishing pad forms a layer of glass film on the surface after machining. This film not only has a mirror gloss, but also transparently shows the inner structure of the stone. The observed pattern is bright and beautiful. The key to rejuvenating a weathered, abrasive polishing pad is to re-form a vitreous film on the surface of the polishing pad.

The technical principle of the polishing pad ground grinding and polishing machine is: the weathered and abraded aging layer of the polishing pad surface is removed to expose the fresh layer, and then the complex effect is formed on the surface of the polishing pad by a mechanical method to form a new glassy film, thereby Restore the natural bright decorative fruit of the polishing pad. The entire process consists of multiple processes without any chemicals.

Solve the problem fundamentally, make the rough and dirty polishing pad smooth and bright, cure the symptoms and cure the problem, and achieve the mirror fruit. The cost of refurbishment is low. The construction is free from pollution, dust, mud splash or noise. For example, shopping malls and hotels can be operated while construction. The traditional ground construction process can be changed. For example, the ground can be first laid or firstly polished and then polished. Not only can the cost be reduced, but also the seams in the construction can be eliminated.

Crystal siliconizing technology for polishing pad

The principle of “Crystal Silicon Infiltration” is to seal the visible and invisible pores on the surface of the polishing pad with a mixed filler of modified resin and silicate powder, and form 0.5 mm silicate crystals on the surface, and the combination of silicone and silica. Body, so that the ordinary polishing pad meets or exceeds the fruit of the medium and high grade imported marble.
The polishing pad “Crystal Silicone” technology is suitable for the retrofitting of old polishing pads and the surface modification of newly made polishing pads, which improves the comprehensive performance index of traditional polishing pads.

After polishing pad modification, there are the following points:

1) The surface finish is high, it can reach 90 degree gloss unit, and the height can reach 98 degree gloss unit, which is equivalent to the quality of imported high-grade marble surface.

2) The surface has a hard height of 5-7, which is close to the surface of high-hardness granite and has good wear resistance.

3) Anti-infiltration, waterproof and anti-fouling (water permeability is less than 0.8), oil resistance, weak acid, alkali, salt spray resistance, the comprehensive performance of natural protection exceeds all current stone products.

4) The service life is up to 30 years. The special formula and structural design ensure that the “Crystal Silicone” board is easy to repair after being put into use, and the maintenance cost and hygienic management difficulty for the floor are greatly reduced.

What are the precautions for using the polishing pad?

The polishing pad has a uniform and standard grain size and good flexibility. It is widely used in the processing of marble, artificial stone and other lines, veneer curved plates and special-shaped stone. It has multiple shapes and different granularity. Colors can be distinguished according to the different needs of customers. Therefore, it is not enough to use only polishing pads. The following aspects also need to be noted:

1. When abnormal sounds and vibrations, rough cutting surfaces or odors are found, the work must be terminated immediately, and the fault should be checked and eliminated in time to avoid accidents.

2. When working, the workpiece should be fixed, the profile should be oriented with the direction of the tool to avoid abnormal cutting, no side pressure or curve cutting, smooth knife feeding, avoiding the impact of the blade and the workpiece, resulting in saw blade damage, or workpiece Flying out, causing an accident.

3. When cutting and stopping cutting, do not be too fast to avoid broken and broken teeth.

4. If cutting aluminum alloy or other metal, use special cooling lubricant to prevent the saw blade from overheating, causing damage such as paste and affecting the cutting quality.

5. The equipment discharge slag tank and slag suction device ensure the smooth flow of water, prevent slag agglomeration and affect production and safety.

6. Dry cutting, do not cut for a long time, so as not to affect the service life of the saw blade and cut fruit; when cutting wet, it should be cut with water to prevent leakage.

What are the uses of these various specifications of polishing pads?

1. Suitable for the processing of artificial stone, granite and marble. It has a complete and standard granular color system and great flexibility. It’s easier to machine lines, chamfers, curved plates and shaped stones. The specifications are optional, the various particle sizes are easy to distinguish, and various grinding machines can be flexibly configured according to needs and customization.

2. Handling and refurbishing various floors and steps of granite, marble and artificial slabs, and flexible use of various hand or refurbished machines according to needs and habits.

What are the treatment methods for concrete polishing pads?

Concrete polishing pads are divided into diamond polishing pads, concrete thick polishing pads, concrete thin polishing pads and concrete polishing sheets. They are usually used on refurbished machines or floor grinders. Different models and sizes are selected according to the matching machine and ground hardness. Water polishing pad or dry polishing pad for floor leveling, rough grinding, fine grinding, fine grinding and polishing.

Leveling treatment:

1. Remove the loose surface layer of the old floor: Use the diamond polishing pad to easily remove the loose surface layer of the floor, and use it for medium and large floor grinding machines.

2. The flat surface treatment of poor flatness: first use the diamond polishing pad to initially level, and then use a thick polishing pad rough grinding and leveling, and then choose the appropriate concrete thick polishing pad or thin polishing pad grinding.

3. Surface treatment of large-area repairing floor: It is recommended to use the diamond polishing pad to grind and level before the surface is cured. After curing, use a thick polishing pad to roughen the leveling. Accurately grasp the grinding time to make the floor treatment simple and easy.

4. Surface treatment of old floor with good flatness: Selecting the thick polishing pad with the appropriate grain size according to the ground hardness can make the ground flatness better, and the later grinding and polishing process will be faster and better.

Rough grinding treatment:

1. After the ground leveling treatment, select a higher-grain size thick polishing pad or a thin polishing pad for coarse grinding, and use it for medium and large floor grinding machines.

2. Terrazzo floor, concrete color sand floor, uniform dry sand hardening agent floor: according to the floor hardness selection thick number of thick polishing pad, supporting medium and large grinding machine can improve the grinding rate and make the ground flatness better .

Fine grinding and fine grinding:

1. The new aggregate hardener floor keeps the surface of the puree: It is better to choose a thin concrete polishing pad suitable for fine grinding. A new floor with good mechanical light is easy to make a uniform surface of the pure pulp.

2. Ground after rough grinding: Select the concrete polishing pad suitable for fine grinding, thick polishing pad and thin polishing pad are applicable. The medium and large grinding machine can improve the grinding rate and make the ground flatness better.

Polishing treatment:

Concrete polishing should be carried out after fine grinding or fine grinding on the ground. Before polishing, the floor should be washed and dried, and dried with a thin polishing pad. The polished fruit is related to the hardness, flatness and pre-treatment of the ground.

Use a thin polishing pad to dry and then use a concrete polishing pad to polish, which can significantly improve the brightness of the ground.

Crystal surface treatment:

If the ground brightness requirement is high, it is recommended to perform crystal face treatment after polishing. Use concrete brightener for floor surface treatment. After spraying concrete brightener, use 6000# concrete polishing sheet (4FP6) to dry and throw, which is easy to bring long-lasting and charming mirror fruit.

Polishing pad life and grinding fruit will be affected by various factors, including ground hardness, grinder weight, counterweight, speed, whether water and water, polishing pad type, quantity, particle size, grinding time and experience. The thin concrete polishing pad can be used with a variety of refurbished machines and grinders. The thick concrete polishing pad is suitable for medium and large grinders to improve the grinding rate and make the ground flatness better.

Concrete polishing pads are divided into water polishing pads and dry polishing pads. Different formulations are used in different ways. Please choose according to the construction method.

What are the mirror stone maintenance steps?

Stone mirror maintenance is based on the improvement of hardness, gloss, lack of clarity and cumbersome process of water wax. The principle is to use the mirror treatment agent plus the heavy-duty processor to rub the stone surface. Under the dual action of chemical and physical, the stone surface layer forms a hard and dense crystal hard crystal layer, which makes the stone surface not easy to be damaged and not easy to stick. Stains, thus ensuring the essence of the stone, is one of the common stone conservation methods.

In other words, the crystal layer separates the source of pollution from the stone, and the only layer of crystal on the stone is contaminated and damaged. After the mirror treatment, the stone surface molecules are denser and the gloss brightness is obviously improved, making the stone surface brighter and more noble. Mirror processing accumulates fruit and value during constant maintenance.

The specific steps of stone mirror processing are as follows:

1. Finishing the surface of the stone floor: Before the crystallization treatment of the stone floor, the surface of the paving is completely flat, no color difference, the diagonal of each stone is flush, the whole ground is cleaned, and the ground is cleaned with dry and clean. There are no sand and impurities on the ground.

2. Stone gap marble glue repair: the overall cleaning is completed, use marble glue to repair small spots on each stone, the gap between the stones, use a small trowel to repair with marble glue, flat, use small Clean the rags and clean the finished parts one by one. The gypsum powder in the travertine must be cleaned; after the marble glue is repaired, it must be dried until the next step.

The so-called jointless grinding process is to fill the gap between the adjacent slabs, which are similar to the slabs, and then grind and polish them with the use of tools and techniques. After being processed in this way, the slate will present a large piece of stone that is not divided as a whole.

3. The overall ground grinding: After the marble glue is dried, use the grinding machine to polish the whole ground, the overall horizontal grinding, focus on the caulking between the stones (the diagonal between the stones) and near the wall, decoration At the edge of the shape and shape, keep the whole stone floor level, finish the grinding, re-cast the marble glue caulking, continue the second grinding with the caulking, and then use the platform refurbished machine with the diamond polishing pad from the coarse To fine, (150 mesh, 300 mesh, 500 mesh, 800 mesh, 1000 mesh, 1500 mesh, 2000 mesh), a total of seven grindings are required. The final ground is smooth and smooth, and then polished with steel wool. The brightness required by the design (70 degrees), there is no obvious gap between the stones.

4. The ground drying treatment: sanding is completed, first use the water suction machine to the overall treatment of the ground moisture, while using the blow dryer to dry the entire stone floor, if the construction period allows, you can also use natural air drying to keep the stone surface dry .

5. Ground crystallization treatment: the ground side sprinkle K2, K3 syrup, while using a multi-purpose washing machine to rotate, use the washing machine with red scouring pad, K2, K3 syrup with the same amount of water sprinkled to the ground, using 175 rpm /min The rubbing machine load 45KG starts to grind, and the heat energy acts to make the surface material formed by the mirror material crystallization on the surface of the stone.

6. The overall ground maintenance treatment: If it is a large void stone (sandstone, travertine, etc.) to be treated with marble protective agent, 12 hours later, then use the scrubber to alternate K2, K3 syrup on the ground, That is, K2-K3-K2-K3-K2 is used five times, and then replaced with a white polishing pad, sprayed with a small amount of K1 syrup, and re-grinded to increase the mirror hardness of the entire ground.

7. Ground cleaning and maintenance: When the stone surface is formed into a crystal mirror surface, use the water absorbing machine to absorb the residue on the ground, moisture, and then polish it with a polishing pad to make the whole surface dry and bright as a mirror. If partial damage can be used for local maintenance. The construction can be completed at any time.

Tips: The choice of mirror agent is more important. If the mirror agent is not well selected, it will have symptoms such as water spots and efflorescence after mirror treatment. A good way to identify this inferior mirror is to make a mirror surface and spill water on the beach. After soaking for a few hours, dry it again. Inferior products will show obvious immersion marks or gloss loss.

Marble polishing steps, precautions and maintenance

Marble decoration is very common. It is often used for cabinet countertops or floor decoration. It has the characteristics of beautiful decoration and good wear resistance. Marble needs to be polished during use, otherwise it will affect the luster of the marble surface. So what are the marble polishing methods, what should be paid attention to in marble polishing, how to maintain after polishing, let’s take a look!

First, marble polishing step

1. Dry grinding

There are many steps in marble polishing, and it is also very complicated. First, the first step is dry grinding. The purpose of dry grinding is to peel the marble. Need to use stone refurbished machine, it can remove the stain on the stone surface, while grinding the pores of the stone.

2. Dealing with stone stains

Usually the marble surface has a lot of stains, so if you want to polish the marble better, you need to deal with the surface stains. If it is a more difficult to treat stain, it can be treated with some chemicals, and the stain is easily removed.

3. Waterproof

Waterproof treatment is also a good foundation for marble polishing. Waterproof treatment is mainly to prevent the wet grinding in the later stage. Some sewage is immersed in the stone, which will affect the polishing, and the sewage will affect the quality of the marble.

4. Slitting, caulking, etc.

In order to ensure the marble surface is very beautiful, slitting, caulking and uniform slitting are very important. The easiest way is to make up the glue. After the glue is added, it can easily achieve the beautiful effect.

5. Simple polishing

Simple polishing is actually very simple, it can be waxed, cleaned, and then polished with steel wool.

6. Surface crystallization

Use the crystal plane machine to match the scouring pad and the detergent powder, and make a good protective layer on the surface of the marble to prevent the stain from entering the inside of the stone. At the same time, it can also prevent scratching, and it can also be very good. Enhance the brightness of the stone. It is understood that this protection period is about one year.

7. Waxing

Waxing is also done to increase the brightness of the marble, but also to protect the surface of the marble. The waxing period is basically three months.

Second, what should I pay attention to when polishing marble?

1. After the marble is finished, the surface water should be treated with a water absorbing machine, and the stone floor should be dried by a blow dryer to keep the surface of the stone dry.

2. If the stone is polished with a large diameter grinding machine, then the grinding depth should be controlled between 1mm and 2mm, and the feed speed should be reduced. If the line speed of the stone grinding machine is large, a large depth of cut is required.

3. Marble grinding should pay attention to, if it is a large gap of stone need to apply a protective agent on the marble surface, and then re-polishing once to increase the hardness of the entire surface of the crystal face.

Third, how to maintain the marble after polishing

1. After the marble is polished, the pores of the stone are completely closed, and the lesion is prone to occur. Therefore, the polished marble needs to be treated for the crystal surface, so that the pores on the marble surface can be opened, so that the marble can be opened inside and outside. Breathable, and the crystal-treated marble is not prone to lesions, but also has a certain anti-fouling and waterproof effect.

2. After the marble is polished, after a period of time, it is necessary to remove the old wax layer with wax water. At this time, it is necessary to carry out large-scale construction, and do not carry out partial construction, otherwise there will be chromatic aberration after construction. Thereby affecting the beauty of the overall effect.

I would like to remind everyone that when cleaning the marble floor, it is best to use a neutral detergent. If a strong acid detergent is used, it will cause certain damage to the marble floor and even corrode the marble surface, causing more unnecessary trouble.

Marble polishing pad use

Marble polishing pads are believed to be familiar to everyone. Because marble floors are widely used in public places, shopping malls, supermarkets, etc., due to the large number of people, it is inevitable that the marble floor will wear out over time. At this time, marble polishing pads will be used, and the ground needs to be refurbished. When it comes to this, many people have already basically understood this product, but after all, there are still many people who are confused about the use of this product. Know how to use it to achieve the effect of ground renovation.

This article will detail and describe some of the considerations in the use and use of the polishing pad from each step used in the marble polishing pad.

1. Clean the surface of the ground. Use a tool to remove the concrete slurry from the gap in the stone. Then remove the dust thoroughly with a brush or a vacuum cleaner. Use a dry and clean ground to clean and clean the ground without sand and impurities.

2. After the overall cleaning of the stone surface is completed, the small damaged points and the stone joints on each stone are repaired with marble glue, and the original damaged surface is first repaired with marble glue close to the stone color. Then use the stone slitting machine to re-cut the slit in the original stone installation to make the width of the gap, and then fill it with marble glue close to the stone color. After the marble glue is repaired, it must be dried before the glue can be dried.

3. After the marble glue is dried, use the sander to polish the whole ground, and polish the whole horizontally. Focus on the caulking between the stones and the edge of the wall, the decorative shape and the special shape to keep the whole stone floor level. Finishing the polishing, re-creating the marble glue, caulking, caulking, and continuing the secondary grinding. Then use the stone refurbished machine with the steel stone polishing pad from coarse to fine. A total of seven polishing and finishing finishes are required. Smooth, and then polished with steel wool, the polishing degree reaches the brightness required by the design, there is no obvious gap between the stones.

4. After the polishing is completed, use the water suction machine to treat the moisture on the ground. At the same time, use the blow dryer to dry the whole stone floor. If time permits, you can also use natural air drying to keep the stone surface dry.

5. Spray the syrup evenly on the ground side. Use a marble polishing machine to grind the enamel. Use a washing machine with a red scouring pad. Sprinkle the syrup with the same amount of water on the ground. Start grinding and heat. The crystal surface material is crystallized on the surface of the stone. The surface fruit formed after the transformation.

6. The overall ground maintenance treatment: If it is a large gap of stone to be treated with marble protective agent ‚ re-polishing times to increase the hardness of the entire surface of the crystal face.

7. Ground cleaning and maintenance: When the stone surface is formed into a crystal mirror, use a vacuum cleaner to absorb the residue and moisture on the ground. After polishing, use a polishing pad to make the whole surface dry and bright. If the surface is damaged, local maintenance can be performed. Construction can be done at any time.

Marble polishing pad has traditional and standardized grain color and good flexibility. It is widely used in the processing of marble, artificial stone and other lines, curved veneer and special-shaped stone. It has multiple shapes and can be used for various grain sizes. Different colors can be used to distinguish them according to different needs of customers. Therefore, it is not enough to use only polishing pads. In the following process, you should also pay attention to these aspects:

1. When abnormal sounds and vibrations, rough cutting surfaces or odors are found, the work must be terminated immediately, and the fault should be checked and eliminated in time to avoid accidents.

2. When working, the workpiece should be fixed, the profile should be oriented with the direction of the tool to avoid abnormal cutting, no side pressure or curve cutting, smooth knife feeding, avoiding the impact of the blade and the workpiece, resulting in saw blade damage, or workpiece Flying out, causing an accident.

3. When cutting and stopping cutting, do not be too fast to avoid broken and broken teeth.

4. If cutting aluminum alloy or other metal, use special cooling lubricant to prevent the saw blade from overheating, causing damage such as paste and affecting the cutting quality.

5. The equipment discharge slag tank and slag suction device ensure the smooth flow of water, prevent slag agglomeration and affect production and safety.

6. Dry cutting, do not cut for a long time, so as not to affect the service life of the saw blade and cut fruit; when cutting wet, it should be cut with water to prevent leakage.

The above is a complete introduction to the use of marble polishing pads. I believe that through the above introduction, we can use polishing pads more flexibly and safely.

Concrete polishing pad renovation process

Concrete polishing pads are specially formulated for use in industrial floors, warehouses, parking lots, concrete floors, cement self-leveling floors, various aggregate hardener floors and liquid hardener floors. Processing is as follows:

Old ground renovation

1. Base surface treatment: the ground water is fully immersed, and the loose surface layer is fully washed with a high-pressure washing machine or a refurbished machine with a hard brush, and the hollow drum portion is treated separately;

2. Damage repair: use water absorption machine to absorb surface water, apply interface agent, use the repair according to the requirements: material repair and maintenance according to the specifications;

3. Leveling: use TFP series concrete polishing pad or metal polishing pad (water mill or dry grinding);

4. Rough grinding: use 50#-200# series concrete floor renovation tablets;

5. Infiltration treatment: according to the standard use of concrete liquid hardener hardening treatment, if the original ground hardness is poor, it is recommended to do an infiltration hardening treatment before rough grinding;

6. Fine grinding: use 200#-300# series concrete floor renovation. If the hardness of the ground after the osmosis hardening meets the construction requirements, sanding will not occur during fine grinding;

7. Fine grinding and rough polishing: use 500#-1500# series concrete floor renovation film;

8. Washing and drying: thoroughly clean the floor with a refurbished machine with a cleaning pad, and dry it with a water suction machine;

9. Infiltration glazing: use concrete permeable brightener or similar products, pay attention to different processing techniques of different products;

10. Fine polishing: use concrete polishing sheet 3000# (select 1-2 particle sizes as needed).
For new ground infiltration treatment, the best polishing pad manufacturers recommend infiltration treatment after “fine grinding”. If sanding occurs on the ground during fine grinding, it is recommended to do an infiltration hardening process before fine grinding.

Precautions

1. According to the needs and experience, choose different types of refurbished machines and polishing pads. The grinding effect will be affected by various factors: ground hardness, grinder weight, counterweight, rotation speed, whether water and water quantity, polishing pad type, quantity, polishing Pad size, grinding time and experience, etc.;

2. According to the ground hardness and technician experience to choose different size number polishing pad, available for selection of granularity number including 30#, 50#, 100#, 150#, 200#, 300#, 400#, 500#, 600#, 800# , 1000#, 1500#, 2000#, 3000#, commonly used granularity number is: 30#, 50#, 150#, 300#, 500#, 1000#, 2000#, 3000#, according to the actual situation, you can use the jump level to select The effect is related to the hardness of the ground, the flatness, the size of the polishing pad, the grinding time and the experience of use. In the whole process, coarse grinding and fine grinding are more uniform and thorough, and fine grinding and polishing will save trouble and better effect. ;

3. Dry grinding, water mill using different formulations of polishing pad, water mill can reduce on-site ash and improve efficiency;

4. It is recommended to clean the ground before polishing the polishing pad for the next size. Otherwise, it will affect the grinding effect.

Quartz polishing pad processing precautions

The masters who have processed the stone will know that some stones are very well processed, and some stones are very difficult to process because the hardness is too high. Especially in the processing of quartz polishing pad, the hardness of quartz stone can reach Mohs 7, so its plasticity is not as easy as ordinary artificial stone and acrylic, and the processing technology is higher than other artificial stone. There are various problems in processing, how to avoid it?

Quartz stone joints should be spliced ​​with 45° anastomosis. When splicing, the connecting surface must be straightened with a straight knife, and the butt joints can be connected seamlessly. Before connecting, the glue color must be tested first, and the color can be spliced ​​before it can be connected. The remaining glue at the joint is removed by a small blade after the gel is not hard. When the glue is hardened, it is polished and the grinding range is not suitable.

Quartz stone will have a trace like a thread when it is connected, but it is not easy to see without careful observation, and it does not affect the appearance. Mainly open hole: When opening the furnace hole, the bottom of the quartz stone plate should have a backing plate, which can not be suspended, and the bearing force should be uniform to prevent cracking during the opening process due to uneven force. Before opening the hole, first strengthen the four sides and the middle of the quartz stone, and then punch the holes at the four corners of the furnace hole. Then use the wire cutter to cut the square shape slowly and evenly. When cutting, the plate cannot be cut through. It should be divided into two steps. Cut, cut the thickness of the sheet by 1/3, and cut the sheet through the two steps to prevent the sheet from cracking.

After the furnace hole is cut into squares, the angle of the arc of the angle grinder is ground into a circular arc angle. The radius of the arc is not less than R10mm. The back of the four corners of the furnace hole is thickened with a small plate of about 120×120mm, and then grinded into a corresponding angle grinder. The arc is thickened on the four sides by a quartz stone plate with a width of 30 mm or more. The distance between the edge of the furnace hole and the rear water barrier is not less than 70mm.

Look at the edging and chamfering: use hard diamond polishing pad, first 50#, after 150#, then 300#; when polishing with Tianbang diamond water grinding plate, start with 500# polishing pad, then use 800# in turn. Polishing pads of 1000#, 1500#, and 2000# are polished. Note that the diamond polishing pad must be hard and must be emphasized with the supplier. The size of the polishing pad is 3 or 4 inches, depending on the needs of the application. After the use of glue: the original glue of the quartz manufacturer should be used, and the glue must be thoroughly stirred before the glue is used.

The glue curing agent is similar to the ordinary artificial stone curing agent, and the relationship between the addition amount and the temperature is as follows:

(1) when the temperature is below 10 ° C, the amount of curing agent added is 1.5-2% of the glue;

(2) When the temperature is between 10 ° C and -20 ° C, the curing agent is added in an amount of 1% of the glue;

(3) When the temperature is between 20 ° C and -30 ° C, the curing agent is added in an amount of 0.5-0.8% of the glue;

(4) When the temperature is above 30 ° C, the curing agent is added in an amount of 0.5% of the glue.

The difference between polished and polished marble polishing pad

Because of the long-term use of marble, the crystal surface brightness and gloss disappeared on the marble surface, which affects the overall decoration design inside the home. Then, when the brightness and gloss of the marble polishing pad disappear, what method can be used to make the marble polishing pad re What about the glow? Generally in this case, we need to polish the marble to re-gloss the crystal face of the marble.

When marble is polished, different polishing and polishing processes are used depending on the type of marble, and the polishing process of the flat plate is different from the polishing process of the arc panel. Therefore, we should pay attention to the following when polishing and polishing.

1. After continuous polishing of the crystal layer and crystal layer after polishing the stone grinding block (commonly known as crystal face care), the pores are not completely closed, and the stone can be breathed inside and outside, and the stone is not easy to be diseased. At the same time, it has a certain waterproof and antifouling effect.

2. After the marble waxing and polishing, the stone pores are completely closed, the stone can not be breathable inside and outside, so the stone is prone to lesions.

The difference between marble polishing and wax polishing

Marble polishing and waxing and polishing can make the stone bright and beautiful, so what is the difference between the two? The best polishing pad manufacturers below mainly introduce the difference between the two in terms of essence, appearance and extension operation.

At present, stone surface treatment is one of the most ideal curing methods for marble. It does not change the structure of the stone, so it does not change the texture of the original stone. After the crystal surface treatment, the stone surface molecules are denser, and the gloss brightness is obviously improved, making the stone surface brighter and more noble. Stone waxing can make the stone color bright. Stone wax is a water-soluble material. When it is used, it will produce a protective film on the top of the product. This will improve the brightness of the stone, but its protective effect on the stone is Limited, poor weather resistance, anti-fouling effect is not ideal, and it is easy to attach dust.

Nowadays, people also find that waxing also causes some harm to the stone, because it is applied as an airtight cover protection material on the surface of the stone. After the pores of the stone are closed, the moisture inside and behind the surface is not released. In the interior of the stone, the stone has been damaged for a long time. Marble grinding is the last step in the process of stone care crystal surface processing or stone light board processing. It is one of the most important processes in today’s stone care, which is different from the marble cleaning and waxing polishing in the traditional sense of cleaning company business.

First, the essential difference

1. Marble grinding polishing is a prelude to stone surface treatment or a necessary process in stone processing. The main principle is to use the pressed grinding block synthesized by mineral acid, metal oxide and other materials to match the pressure of mechanical grinding disc, high-speed grinding force, frictional heat energy, and the physical and chemical cooperation of water on the smooth surface of marble. Thereby forming a new layer of bright crystals. This crystal layer has an ultra-bright, clear luminosity. The luminosity can reach 90-100 degrees. This crystal layer is a modified crystal layer of a stone surface layer (1-2 mm thick).

2. Marble cleaning is a prelude to marble waxing and polishing, marble cleaning waxing polishing is a relatively popular marble cleaning and maintenance protection measures in the early 80s-90s, and now has lost the market and the meaning of existence. Its essence is a thin coating of acrylic resin and emulsion polymer covered on the surface of the new stone (polished board), which is often referred to as water wax or floor wax. The high-speed, low-pressure polishing machine is combined with the fiber mat to rub the surface of the stone to make the resin coating more bright. Due to the product update, later appeared special light wax, wax-free, etc., this coating is similar to the oil varnish on the wooden floor.

3. The polishing process of the grinding block before the marble care crystal surface treatment is the physical and chemical cooperation process between the stone surface layer and the chemical. The surface layer of the stone is completely integrated with the bottom layer, and there is no separation layer.

4. The wax layer on the marble waxing is attached to the surface of the stone, a layer of resin film, and there is no chemical reaction with the stone itself. This wax layer can be shoveled with a blade to cut the wax film off the surface of the stone.

Second, the difference between representation

1. Polishing and polishing of marble grinding blocks is the prelude of crystal face care stone care. After polishing and polishing, the luminosity is high, the definition is high, the wear resistance, the resistance to stepping, and the scratching are not easy. It is the true embodiment and value extension of the stone use function.

2. The stone after polishing and polishing the luminosity is low, the luminosity is not clear, and it is very fuzzy, not wearable, not water resistant, easy to scratch, oxidized and yellow to reduce the essence of the stone.

Third, the difference between extension and operation

Generally speaking, the steps of the appeal can basically handle the marble surface, but sometimes we encounter artificial stone like jazz white and resin. After the completion, the surface may not be very bright, we can spray A2 again. The syrup is ground to 3000#, then repeated with nano-pad, with marble mirror complex cream NO2, 2X mirror lock bright knife into the milk Q5 for polishing, the effect of water bright will be much better than before.

How to choose polishing pad for floor construction

We all know that whether it is in construction or road construction, it will involve the construction of the floor. For the construction of the floor, polishing pads will be used. There are many kinds of polishing pads, such as water polishing pad, soft diaphragm and iron diaphragm. Wait, how do we choose to face such a wide range of polishing pads? This is indeed a difficult thing for newcomers to build. Don’t worry, Tianbang will reveal how to choose a polishing pad for the construction of the floor.

First, how to choose polishing pad for floor construction

Commonly used concrete polishing pads mainly include the following:

Polycrystalline diamond polishing pad: used to remove epoxy coating, it needs to be used when the coating is thicker; concrete diamond polishing pad: used for concrete floor leveling and old ground renovation; concrete thick polishing pad: usually refers to thickness more than 5mm Diamond resin polishing pad for concrete floor leveling, rough grinding, fine grinding, fine grinding and polishing; concrete thin polishing pad: usually refers to diamond resin soft polishing pad with thickness less than 5mm, used for coarse grinding and fine grinding of concrete floor. Fine grinding and polishing; concrete polishing: usually made of rayon, wool or other animal hair, and some products are also added with some abrasives and polishing accessories for the polishing of concrete floors;

How do we choose and use such a wide range of polishing pads? To understand how to properly select and use polishing pads, we need to understand some of the following terms about flooring and grinders:

1. The flatness of the ground: artificially smeared the leveled ground or the old ground with serious looseness and damage. It is necessary to level or remove the loose surface layer. It is necessary to use a high-power grinding machine and select a concrete diamond polishing pad to grind it. Suitable for leveling polishing pads. The level of flatness of the cement self-leveling floor or the trowel machine leveling is better. Only the diamond resin polishing pad can make a beautiful polished floor, and the polishing pad is also relatively economical.

2. Hardness of the ground: The concrete used in the design and construction of concrete floors is indicated by the number, which is C20, C25, C30, etc., which we usually talk about. The higher the number of normal concrete, the better the strength and hardness of concrete. However, due to various factors, the concrete marking and the ground hardness often do not correspond. The hardness of a concrete floor is usually expressed in terms of Mohs hardness. The hardness of the concrete floor is usually between 3-5. On the construction site, we can replace the Mohs hardness tester with some substitutes to understand the hardness of the ground: the hardness of the damaged scratches can be less than 5 by using nails and keys. Otherwise, Hardness is greater than 5.

3, the weight and speed of the grinder: floor grinders are usually divided into small, medium and large. Generally speaking, the larger the machine, the higher the power and the higher the efficiency. In actual use, the larger the machine, the better. The grinding machine with too large and too heavy is highly efficient, but it often leads to excessive grinding and increase. Construction costs. Experienced workers will adjust the machine speed, moving speed, number of polishing pads and machine weight according to the characteristics of the machine, reduce construction costs and improve construction efficiency.

4. Types and particle size of polishing pad: The most commonly used abrasives for floor treatment are PCD polishing pad, metal-based polishing pad and resin-based polishing pad. PCD polishing pad is used to remove thick coating on the floor surface. Metal-based polishing pad is used for Floor surface pretreatment and rough grinding treatment, resin-based polishing pad is used for surface rough grinding, fine grinding, fine grinding and polishing treatment. It refers to the size of diamond particles contained in the grinding tool. The lower the number, the larger the particle size.

PCD polishing pad is not divided into grain size, but it is directional, which should be paid special attention when using it; metal polishing pad is usually divided into several numbers such as 30#, 50#, 100#, 200#, etc. Which granularity number to use should be determined according to the ground conditions. For example, if the ground flatness is not good or the surface is loose, it may be necessary to use a 30# metal polishing pad to remove the loose surface layer to level the ground. The ground that needs to make a matte and grindstone effect is usually required. Use 50# or 100# metal polishing pad; resin polishing pad is widely used, grain size No. 30#-3000#, different grain size numbers are distinguished by different color adhesive cloths, used for ground rough grinding, fine grinding, fine grinding and polishing. Treatment, resin polishing pad has the difference between hard polishing pad and soft polishing pad. Hard polishing pad has better leveling effect. It is more suitable for medium and large floor grinding machines. Diamond soft polishing pad has better polishing effect and is suitable for various kinds. Type of floor grinder.

Hard concrete floors are recommended to use soft base metal polishing pads, use sharp resin polishing pads, increase machine weight, reduce mill speed, and reduce forward speed.

Soft concrete floors are recommended for hard metal polishing pads, durable resin polishing pads, increased mill speed, and faster forward speeds.

The quality of the domestic concrete floor is mostly not ideal, especially the renovation of the old ground, the flatness is not good, the ground is loose, the hardness is very poor, the water mill process produces a large amount of mud, and the abrasive consumption is particularly severe. On such a ground, it is recommended to use medium and large ground. Ping grinding machine, after shaving and dry, use dry dry grinding, first select 30# hard base metal polishing pad to remove loose layer to leveling treatment, then use 100# medium hard or soft base metal polishing pad to grind, flatness and foundation The hardness is handled well, and the back is much simpler.

Second, the correct choice of polishing pad benefits

The correct selection of polishing pad can improve the efficiency and reduce the cost. The selection and use of the polishing pad are regularly followed: the ground leveling and rough grinding use diamond polishing pad or concrete thick polishing pad; the fine sand polishing pad can handle the good without coarse sand. Polishing pad; increasing the weight of the grinder or increasing the speed can improve the efficiency; try not to use the polishing pad with the skip number; the dry grinding saves the consumables more than the water grinder, but the water grinding treatment will make the ground more even and delicate; wash the floor and dry it after use The thin polishing pad has a better effect of high-speed dry polishing; the use of a sponge polishing sheet can improve the brightness of the floor.
