What are the renovation and transformation processes of industrial floors?

The ground is frequently used in the building, so it is easy to be damaged. Due to the limitation of technology, many old grounds (such as epoxy, emery, terrazzo, floor tiles, cement floors, etc.) gradually exposed their defects and appeared different The problem of form and degree, so to a certain degree, needs to be refurbished. Diamond polishing pad manufacturers are coming to introduce you to several renovation construction techniques commonly used in industrial floor renovation.

The construction process of epoxy resin floor

6-inch-diamond-polishing-pads

1. Treatment of plain land: polishing, repairing, and dust removal according to the condition of the plain land

2. Epoxy primer: use epoxy primer roller coating with strong permeability and adhesion to enhance surface adhesion

3. Epoxy soil approved: According to actual needs, it shall be constructed several times, and the requirements shall be smooth and free of holes, and no batch of knife marks and sanding marks shall prevail

4. Epoxy topcoat: two coats of soluble epoxy topcoat or anti-slip topcoat

5. Construction is completed: You can only get on people after 24 hours, and you can press hard after 72 hours. (25℃ shall prevail, the low temperature opening time needs to be extended appropriately)

Construction technology of concrete sealing and curing agent floor (mirror type)

5-inch-diamond-polishing-pads

1. Grassroots treatment: before construction, clean up debris, oil stains, curing agents, etc. on the ground. Cement-based repair mortar was used to repair potholes and cracks on the ground and cured for 3 days.

2. Polishing the ground: the surface quality is poor and rough: install a rough diamond module on a terrazzo machine (7.5KW machine), add water to grind the ground, and then change the fine grinding head separately, and then grind the ground with the fine grinding head. The same process is water milling) until the ground is smooth. After grinding the ground, clean the ground with water and at the same time use a vacuum cleaner to suck up the sewage. For better, smooth new wear-resistant floors, you can directly apply concrete sealant curing agent.

3. Brush the concrete sealing curing agent: After the floor is cleaned, let the surface air dry, you can start to apply the concrete sealing curing agent. Use a roller or sprayer to evenly brush the curing agent on the ground. The average amount of coating is 10㎡/kg. If the base surface is poor and the permeability is strong, it must be painted twice after 1-2 hours; after about 1-2 hours (before the material is dry and shiny), spray some water on the ground to moisten the material, Use a broom or floor mop to scrub the surface to make the material penetrate into the ground, and repeat 2-3 times, then rinse the ground to remove the excess material on the surface.

4. Ultra-fine polishing (mirror fruit): In order to increase the gloss and brightness of the ground to achieve mirror fruit, 1.1KW high-gloss polishing machine can be used, and 500 mesh, 1000 mesh, 2000 mesh, and 3000 mesh diamond polishing pads can be attached to the disc. Water the super-fine polished floor.

Construction technology of wear-resistant floor

4-inch-diamond-polishing-pads

1. Removal of laitance: Use a machine equipped with a disc to slowly and evenly destroy the laitance on the surface of the single concrete.

2. Spreading material: Spread the specified amount of 2-3 wear-resistant material on the concrete surface in the initial setting stage. After the wear-resistant material absorbs water, the mechanical operation of installing the disc is carried out, and the wear-resistant material is hardened to a certain stage, and the wear-resistant material is spread twice.

3. Disc operation: After the wear-resistant material absorbs water, perform at least three mechanical operations to install discs. The speed of the machine depends on the hardening of the concrete. The mechanical trowel should be crisscrossed.

4. Surface finishing: The final finishing of the wear-resistant floor material is processed by mechanical trowel or manual trowel. When finishing, it should be crisscrossed. The angle of the iron plate and the speed of the machine should be adjusted according to the hardening of the ground surface. .

What are the differences between stone depth and shallow renovation?

Due to various factors, such as natural factors, man-made factors, or the stone itself, it will cause the pollution of the stone to lose its luster. At this time, it is necessary to renovate the stone to restore its original natural texture and gloss. Stone renovation can be divided into deep and shallow renovation according to the degree of contamination, so do you know the difference between deep renovation and shallow renovation?

The difference between stone depth and shallow renovation

6-inch-diamond-polishing-pads

1. The difference in construction process

(1) Shallow renovation process: If there is old wax on the ground, wax it first, and then use 800# diamond polishing pad and clean water to polish for ten minutes. Pay attention to adding water during the polishing process to keep the ground moist and suck it away with a water suction machine. Sewage to prevent sewage from polluting the ground a second time. Change 1500#, 3000# polishing pads, diamond polishing pads, and polish them one by one using the above method. After all the renovation procedures are completed, wash with clean water and absorb the water on the surface of the stone. The light renovation of the marble is completed.

(2) Deep renovation process: Before renovation, the holes should be repaired. The dirt in the holes should be cleaned first, and then the stone should be dried. According to the color and reflective characteristics of the original stone, epoxy glue or unsaturated resin glue should be used. , After toning, repair, use weighting machine, refurbished discs and diamond polishing pads of different meshes to polish one by one. The polishing method and precautions are the same as those for light renovation.

2. The difference between renovation costs

The difference between deep renovation and shallow renovation of stone lies in the difference in cost. In fact, the difference in cost is caused by the difference in construction procedures. There are more construction procedures for deep renovation than for shallow ones, and more materials and tools are used, so the cost of renovation is higher than the cost of shallow renovation.

Marble-floor-polishing-pads

The degree of stone renovation

There are three levels of renovation of stone, in addition to the shallow renovation and deep renovation we know, there is also a medium renovation. Below we will specifically introduce these three levels of renovation.

1. Shallow renovation of stone

The surface of the stone was slightly scratched. During the overall grinding and renovation, the subsequent maintenance of the stone was not in place, which caused the stone surface to completely lose its luster. To restore the surface of the stone as bright as new, a light renovation process can be used for renovation.

2. Moderate renovation of stone

When the surface of the stone loses its luster, can not reflect the object at all, or does not have excessively deep scratches, a moderate renovation process can be used for renovation. Use diamond polishing pads of different meshes to polish one by one. The polishing method and precautions are the same as those for shallow renovation.

3. Deep renovation of stone

After the stone was laid, it was put into use without the overall grinding and renovation, resulting in insufficient ground flatness and gloss. Another situation is that the stone surface is completely lost after the overall grinding and renovation are put into use for a long time Luster, holes, weathering, severe corrosion, colloid shedding, black seams, etc. and deep scratches, these all need to be deeply refurbished to restore the brightness of the new stone.

Spiral polishing pad

Stone renovation steps

1. Clean the original filling between the stone gaps first, and then use a special stone slitting machine to neatly cut and slit the center gaps of the original stone installation to reduce the width difference of the gaps between the stones, and then use a stone close to the color of the stone. Marble glue fills it up. (Note: If the center seam has been done before, there is no need to re-sew).

2. Use marble glue that is close to the color of the stone itself and mix the marble glue to make it close to the original stone color to improve the overall feeling and achieve the ideal visual effect.

3. Fill the adjusted marble glue. Since the marble glue will shrink to a certain extent after it is completely solidified, the marble glue should be slightly higher than the stone level, so that it will not be filled multiple times.

4. Using polishing pads and polishing fillers to make it a horizontal surface with the stone, increase the overall sense of the stone, and solve the problem of height between the gaps, and prevent the gaps from turning black again. Use a granite refurbishing machine with a special cutting edge grinding sheet to carefully polish the cutting edge to make it a flat surface with the stone.

5. Use a special granite polishing machine to grind the stone from coarse to fine polishing pads of No. 50-3000, so that the ground is bright and smooth as new.

6. Use crystal powder and crystal agent to polish with crystal surface grinder. Under the heavy pressure of grinding, the stone and crystal powder will undergo a comprehensive physical and chemical reaction under the action of high temperature to form a dense and hard crystal protective layer. After crystallization, it can enhance the color and brightness, and also has the functions of waterproof and oil proof.

To sum up, the difference between deep renovation and shallow renovation of stone lies in the two points of construction process and renovation cost. It is also because of the different construction processes that the corresponding renovation costs are different. In addition, in addition to deep and shallow renovation, There is also a moderate renovation, which is used when the stone cannot fully reflect the object or the scratches are not too deep. When refurbishing, a diamond polishing pad is required for polishing.

What is the process of polishing and waxing marble floors?

The most important and critical step in the construction of the marble floor is the polishing and waxing of the floor. When polishing and waxing the marble cement floor, first use a multifunctional brushing machine with a neutral cleaner or waxing agent to clean the floor. Clean, remove the old wax on the ground, make the stone floor free of debris, dust, and stains. Let’s take a look at the marble floor polishing and waxing construction process.

When waxing the stone floor, the floor must be kept dry. First, use a wax mop to evenly coat the back cover and bottom wax on the floor. The bottom wax should be applied in 3 layers, which can be dried by a blow dryer. After the base wax is dried, use wax to drag two layers of high-speed surface wax on the stone floor, and then air-dry the floor. After the wax surface is dried, use a high-speed polishing machine with a marble polishing pad to perform uniform and uniform polishing.

Planing and maintenance of marble floors: waxing and recrystallization

1. Let me talk about waxing first. Waxing and polishing marble is indeed an effective maintenance method, but there are many disadvantages in this kind of marble maintenance.

(1) The wax noodles absorb dust, the ground after treatment is prone to a gray feeling, and pedestrians will leave clear footprints afterwards;

(2) The wax layer closes the pores of the marble, and the moisture inside the marble cannot leak out, causing the marble to appear lesions;

(3) The wax layer has a soft texture and is susceptible to abrasion, which cannot truly meet the requirements of protecting marble.

Marble-floor-polishing-pads

2. Recrystallization treatment. Recrystallization treatment of marble is a popular marble maintenance method. Marble recrystallization is divided into two parts, one part refers to the machine tool part, the other part is the special chemical material part; the chemical material is also There are two types: one is granite recrystallization, the other is marble recrystallization.

The basic principle of stone crystallization is to combine some special chemical materials with the structure of the marble surface with the help of the heat generated by mechanical friction to produce a new hard crystal layer. Using these stone recrystallization systems to maintain granite and marble can be Make the marble floor get a bright, fresh and natural effect. It can also improve the abrasion resistance of the marble surface and make it more durable.

In general, this kind of maintenance is sufficient for the granite floor once every two years. However, due to the difference in texture of the marble floor, it generally takes about 6 months to do such maintenance, but the specifics also depend on the degree of wear on the marble surface.

Before crystallization, the marble needs to be professionally cleaned in order to ensure the construction effect. Practitioners must establish a scientific and rigorous working attitude.

Cleaning tools and materials:

Tools: floor scrubber, nylon brush plate, water suction machine, mop, bucket.

Material used: weak alkali or neutral detergent.

Operation method:

Spiral polishing pad

1. Pour the diluted stone cleaning liquid into the washing machine, move forward from back to front, and walk in a straight line to avoid omissions.

2. Start the water suction machine at the same time of scrubbing, and absorb the sewage while scrubbing. For areas that cannot be washed by the scrubber, you can use mop foam cleaner to wring out and scrub.

3. After cleaning with detergent and soaking up the ground sewage, wash it again with clean water in the same way, and then it can be completed by soaking up the water.

4. Matters needing attention: It is forbidden to use acidic cleaners and powdered cleaners to clean the floor, otherwise it will damage and corrode the marble surface.

5. Standard: clean and translucent, no stains, no marks.

Daily marble maintenance method

Wipe the marble regularly with a slightly damp cloth with a mild detergent, and then dry and polish it with a clean soft cloth. If it is difficult to handle the severely worn marble, it can be polished with steel wool or an electric sander, or wiped carefully with a liquid scrubbing agent. You can choose to use lemon juice or vinegar to clean the stains on the marble surface, but it should be paid special attention that the lemon should not stay for more than 2 minutes. Otherwise, the lemon will be absorbed by the marble and cause new stone pollution. Repeat the operation if necessary.

Then wash and dry. Slight scratches can be protected with a special marble care agent. If it is old or valuable marble, it should be handled by a professional stone maintenance company.

Method of polishing cement floor:

There are generally three ways to polish the cement floor. The cement floor is waxed and the cement floor is transformed into a permeable floor and cement floor crystallization. The construction methods of these three methods are similar, and they can all have a polishing effect and obtain a good cement floor surface treatment effect.

Cement floor polishing and floor waxing

For the new ground with better light collection, you can directly apply the cement floor polishing wax to the ground evenly, and then use a floor polishing machine and a floor polishing pad for polishing. The polishing area should not be too large each time to achieve gloss and no scratches. Only when there are traces can the next area be polished until the waxing and polishing treatment of all the ground is completed. For the old cement floor with wear, dust, pits and cracks, it needs to be ground by a ground grinder. After filling the pits and cracks, waxing and polishing can be carried out. The method is the same as before.

The advantages and disadvantages of waxing and polishing cement floors

Advantages: convenient and quick construction, obvious effect, waterproof and anti-fouling.

Disadvantages: the retention time is not long, the anti-slip effect is not good, and it is easy to get dirty after long-term use.

Transformation of cement floor polishing into permeable floor

The method of transforming cement floor polishing into penetration floor:

For new cement floors with better light collection, you can directly spray the concrete sealing curing agent on the ground, and then use brushes, hairs, etc. to keep the ground moist for about 1 hour, then clean the ground with water, and then polish it. can. For defective old ground, it is necessary to fill in potholes, cracks, control oil pollution, etc., and then do grinding and polishing treatment before spraying concrete sealing curing agent for the next step of construction.

Advantages and disadvantages of cement floor polishing:

Advantages: fast and convenient construction, high hardness, good wear resistance, anti-fouling, and long use time.

Disadvantages: In order to achieve high brightness, it needs to be polished without polishing.

Crystallization treatment of cement floor polishing

The method of crystallization treatment of cement floor polishing: first rough and fine polish the floor with a floor grinder, and then polish the floor. After the floor has a certain luster, dry the floor. Spray the ground crystallizer on the ground of 1 square meter, and use a crystallizer with steel wool and scouring pad to do left and right grinding treatments, until a uniform high-gloss ground appears before moving to the next area. Cycle in this way until the construction area used. Corresponding repairs are required for defective old cement floors.

Advantages and disadvantages of crystallization treatment of cement floor polishing:

Advantages: high surface hardness, good gloss, anti-fouling, waterproof and abrasion resistance.

Disadvantages: long construction time and need to be polished.

The above is the relevant introduction about the marble floor polishing and waxing construction technology. I believe you will have a simple understanding of this after reading it. If you need it, you can continue to pay attention to us.

Stone dry hanging process and points for attention

The stone dry hanging process mainly uses section steel horizontal and vertical keels and pendants to form the stone into the wall. Since there is no internal bonding material and no wet work, it can improve the quality of the project and speed up the construction period. At present, the wall and column surfaces of most public spaces adopt dry hanging technology. Dry-hanging of stone wall, because it needs to be fixed on the base wall, the internal craftsmanship of different base wall materials is different, the wall height is different, and the base keel is also different.

1. Stone dry hanging process

Construction preparation→laying out the line→buried board installation→steel skeleton production and installation→stone installation→repair and protection.

2. Main construction methods

Quartz-stone

① Construction preparation:

a. According to the design drawings, carry out measurement and setting-out on site, and deepen the drawing of drawings according to the measurement results.

b. Perform stone typesetting and numbering, confirm the order form, and prepare for stone processing and supply.

c. The treatment of the base body, the verticality and flatness of the base body wall shall be checked, and if necessary, gouge and trim.

②Pay off the line:

According to the design requirements, lay out the skeleton, facing outline and horizontal datum line on the ground and pop up the horizontal datum line on the wall, and place the vertical channel steel line of each part.

③Buried plate installation:

Determine the position of the buried slab according to the position of the vertical keel channel steel, and fix the buried slab with expansion bolts on the concrete beam and wall. It is recommended to use 5-8mm thick steel plates to fix with φ10 metal expansion bolts. The upper and lower spacing of the buried plate should not be greater than 3000mm. The horizontal spacing is the same as the vertical keel spacing, generally less than 1000mm.

④ Steel skeleton production and installation:

The wall where the steel frame needs to be installed is reasonably arranged with the vertical keel of the steel frame according to the dividing line of the projectile, and the spacing is generally controlled at about 1000mm. The vertical keel is generally channel steel, and the vertical keel is fully welded to the four sides of the buried plate. The horizontal keel is made of galvanized angle steel, and the spacing depends on the size of the stone. It is fully welded and connected with the vertical keel. Before installation, the angle steel is pre-punched on the side of the angle steel for fixing the pendant. The horizontal deviation of the horizontal keel should not exceed 3mm. After the steel frame is qualified, all welded parts shall be treated with rust prevention.

⑤ Stone installation:

a. Insert fixing bolts on the steel frame and insert stainless steel or aluminum alloy fixing pendants.

b. Fix the marble polishing pad on the special mold according to the design size, and make grooves on the upper and lower ends of the stone. The groove depth is about 15mm, the distance between the groove edge and the front of the board is about 15mm and keeps parallel, and the back is opened with a groove so that the dry hanger can be embedded in it.

c. Insert the upper groove of the lower stone with AB structural glue, insert the connecting pendant, and insert the lower groove of the upper stone.

d. Temporarily fix the upper stone, inlay with stainless steel pendants, and fix it with AB structural glue after adjustment.

⑥ Repair protection:

Cover the installed stone wall with pearl film to ensure that the area of ​​2m above the ground is covered well to protect the finished product.

Parking-lot-floor

Focus on controlling the main parts

1. Regarding the size and spacing of the keel and the base size of the stone dry-hanging wall, the vertical keel of the stone dry-hanging wall generally adopts 5# -8# channel steel, which determines the channel steel specification generally to connect the channel steel to the wall. The fixed point distance, that is, the upper and lower spacing of the fixed buried plate is related. The size of the horizontal keel is generally related to the spacing of the vertical keel and the size of the stone plate.

Specific specifications can be obtained by calculation. Generally, according to experience, the following values ​​can be used: the distance between the bottom and bottom of the buried plate is not more than 2.5m, and the vertical keel can choose 5# channel steel, if the thickness of the stone is more than 30mm. The upper and lower spacing of the buried plate is between 3m-4m, and it is recommended to choose 8# channel steel; the horizontal spacing of the vertical keel is 1m, and the vertical spacing of the horizontal keel is within 1m (the stone plate is also 1m). The horizontal keel can use 50 angle steel.

2. Indoor stone wall is dry hanging. Due to the different types of stone, the characteristics of the stone should be considered when typesetting and dividing the grid. Generally, granite stone has a hard texture and high strength, and the plate can be enlarged. Marble has poor strength and is easy to break. The size of the plate should not be larger than 1M2. If necessary, the back side should be reinforced with reinforcing ribs. The thickness of the stone should not be less than 20mm. If the wall height is higher than 4 meters, the thickness of the stone should not be less than 25mm. After the marble stone is slotted, to strengthen the strength of the pendant part, the structural glue can be used to paste the reinforced stone on the back of the slotted part.

3. If the wall has no concrete ring beams and the distance between structural beams is greater than 4 meters, use wall bolts to fix the buried slab if necessary, and add connection points in the middle.

4. The stone pendant is generally located between two stone plates. The upper and lower short grooves of the pendant just fix the two plates. For the bottom, top and special shaped parts, pick pieces can be used to fix the stone. Indoor stone wall dry hanging, in terms of craftsmanship, should actually be part of the stone curtain wall. Many process requirements are basically the same, except that the wind load on indoor stone dry hanging is less affected. Generally, the wall height of dry hanging Not high, the steel frame method should be simplified compared with the curtain wall.

At present, most of the methods still use this method of steel frame welding and pendant installation. As the process progresses, it will also adopt a unitary or factory assembly process like an outdoor stone curtain wall.

Detailed explanation of mirror floor renovation technology

The mirror floor is a finely treated concrete floor that is ground and polished with high-efficiency grinding equipment and diamond tools.

This kind of ground is not only beautiful in appearance, but also has a good working environment. This kind of ground has good durability and low cost throughout its life. It is both beautiful and economical. It is an ideal ground for industrial buildings and public buildings.

Floor mirror treatment is a concept of overall fine treatment of concrete floors. This technology uses a mechanical method to finely treat the surface of the concrete. It removes the cement paste that is low in strength, easy to dust, and is not wear-resistant on the top surface of the concrete, and exposes the high strength concrete entity below it. The result is a completely uniform, high-quality, functional and aesthetic concrete surface.

1. Features of mirror floor

Smooth surface, high-gloss polished surface effect, high-strength wear-resisting, long life, low maintenance cost, high economic efficiency.

Marble

2. Mirror floor renovation process

(1) First, use floor polishing equipment to smooth the ground.

(2) Clean up the dust on the floor after smoothing, and then apply a layer of curing agent on the floor.

(3) Fill the gaps and holes between the terrazzo floors with floor fillers, and then fill them with reinforcement.

(4) Ground dry grinding equipment polishes the ground, and finally uses polishing paste to mirror the ground.

3. Precautions for mirror floor renovation

(1) The floor must be thoroughly cleaned before mirror treatment, and it must be kept dry.

(2) The equipment for mirror treatment should not be too light. The weight of brushing the ground that is too light is insufficient and the effect is relatively poor. The weight, power and speed of the machine are the key effects that affect the ground effect.

(3) The site of the terrazzo mirror surface treatment must ensure that no sand and dust enter, and the stains on the surface must be cleaned and kept dry after polishing.

Ceramic-tile

4. Scope of application

Widely used in various industrial plants, warehouses, distribution centers, garages, supermarkets, etc.; not only suitable for new concrete, wear-resistant floors, terrazzo floors, and further improve the beauty and durability of the floor, especially for old concrete, problems Refurbishment of wear-resistant floor and terrazzo floor extends the service life of the floor, reduces costs and saves time.

5. Product features

Improve the various physical strengths of the substrate. Over time, the intensity continues to increase. Improve chemical resistance and weathering resistance. Increase water tightness and increase the surface strength of mortar.

Concrete floor polishing pad construction process

Marble-floor-polishing-pads

1. Leveling treatment

(1) Removal of the loose surface layer of the old floor: The loose surface layer of the floor can be easily removed by using Yiheng Diamond Grinding Sheet. It is recommended to use a medium and large floor grinder.

(2) Surface treatment of the floor with poor flatness: first level with diamond grinding discs, then rough grinding with thick grinding discs, and then choose suitable concrete thick grinding discs or thin grinding discs for grinding treatment.

(3) Surface treatment of large-area repaired floor: It is recommended to grind and level the ground with a diamond polishing pad before the ground is completely cured, and then use a thick polishing pad to rough-grind and level after the penetration of the sealing curing agent is chemically cured. Ping handling becomes simple and relaxed.

(4) Surface treatment of the old floor with good flatness: Choose a thick abrasive disc with a suitable particle size according to the hardness of the ground, which can make the flatness of the ground better, and the later grinding and polishing process will be faster and better.

2. Coarse grinding treatment

(1) After the ground is leveled, choose a thicker or thinner grinder with a higher particle size for rough grinding. It is recommended to use a medium and large floor grinder.

(2) Terrazzo floor, concrete colored sand floor, and dry-spread hardener floor with uniform exposed sand: Choose coarse and thick grinding discs according to the hardness of the floor. The matching medium and large grinders can improve the grinding efficiency and make the ground smoother it is good.

Spiral polishing pad

3. Fine grinding and fine grinding treatment

(1) The newly made aggregate hardener ground maintains the surface effect of the original slurry: it is better to choose a thin concrete grinding plate suitable for fine grinding. A new floor with good mechanical finish is easy to make a uniform surface effect of the puree.

(2) Ground after rough grinding: Choose concrete grinding discs suitable for fine grinding. Both thick and thin grinding discs are applicable. The matching medium and large grinders can improve the grinding efficiency and make the ground smoother.

4. Polishing treatment

Concrete polishing should be carried out after the ground is finely ground or finely ground. The floor should be cleaned and dried before polishing. It is recommended to use a thin abrasive disc for dry polishing. The polishing effect is related to the hardness, flatness and pre-treatment effect of the floor. After dry polishing with a thin polishing pad, polishing with a concrete polishing pad can significantly improve the brightness of the ground.

5. Crystal face treatment

If there is a higher requirement for the brightness of the ground, it is recommended to perform crystal surface treatment after polishing. It is recommended to use concrete brightener for floor crystal surface treatment. After spraying concrete brightener, using 6000# concrete polishing sheet dry polishing, it is easy to bring a lasting and charming mirror effect.

The life of the polishing pad and the polishing effect will be affected by various factors, including the hardness of the ground, the weight of the grinder, the counterweight, the speed, whether to add water and the amount of water, the model, quantity, particle size of the polishing pad, the polishing time and use experience, etc. The concrete floor polishing pad produced by our company can be used with various refurbishing machines and grinders.

How to use diamond polishing pad

Diamond polishing pad is suitable for portable electric or pneumatic grinding machine, and then the joint is connected, the power is 750-1500W, and the number of revolutions is 2000-10000. When working, apply a certain pressure to the machine while running water on the surface of the stone to be ground 4-5 times, and then the finer No. 1 grinding disc can be replaced.

Many people are accustomed to using a polishing pad, because the polishing pad is polished deeper, it is not prone to scratches, and there is no dust. Dry grinding is relatively shallow compared to grinding, and the amount of dust is relatively large, and scratches are more likely to occur.

In fact, the water mill cannot meet all different floors, especially the ground with very poor strength and severe sanding. Such ground cannot be blistered. If it is a water mill, I am afraid that the loess can be seen. It does not matter. You can choose dry grinding or sanding. As long as the ground is cleaned up and no gravel is brought into the chassis, there will be no scratches.

The dry ground will be more delicate and gloss better. According to many years of experience, choosing high-quality polishing pads has better wear resistance, which can save you more costs.

Requirements for the use of diamond polishing pads

 

1. Before work, the diamond polishing pad must be fixed, and the positioning of the profile must be in accordance with the direction of the knife, so as to avoid abnormal cutting. Remember that you must not apply side pressure to the cutting of the curve, so the cutter The entry of the diamond pad must be stable, and serious impact between the blade and the workpiece should not be allowed. If the impact is too large, it will definitely cause accidents such as damage to the diamond polishing pad or flying out.6-inch-diamond-polishing-pads

2. During work, if there is abnormal vibration or sound, or the cut surface is rough, and when there is a peculiar smell, you must stop working immediately, take timely inspection and treatment, and work only after the failure is determined to avoid unnecessary failures .

3. Regardless of whether it is starting or ending cutting, do not allow the feed speed to be too fast, because if the speed is too fast, it is easier to cause tooth breakage and damage. If you need to cut metal or aluminum alloy, you must use a special cooling lubricant, because if the diamond polishing pad is overheated, it is easier to produce paste teeth, or other aspects of damage, no matter what kind of damage will affect the entire cutting the quality of.

4. If cutting aluminum alloy or other metals, special cooling lubricants should be used to prevent the polishing pad from overheating, resulting in paste teeth, and other damage, which affects the cutting quality.

5. The equipment chip trough and slag suction device ensure unobstructed, to prevent the accumulation of slag and block, which affects production and safety.

6. When dry cutting, please do not continue cutting for a long time, so as not to affect the service life and cutting effect of the polishing pad; wet cutting should be cut with water to prevent leakage.

The difference between dry polishing pad and polishing pad

Concrete dry polishing pad is a kind of polishing pad for dry grinding of the floor. There is also a polishing pad. Its usage is different. What is the difference? This is the question most asked by everyone, because they are different in nature, and the methods and types used are also different. Today, I will mainly explain the difference between different types of concrete dry polishing pads and water polishing pads.

Dry polishing pad

Dry polishing pads are mainly used for dry grinding processing of various types of stone surfaces. They are flexible processing tools made of diamond as abrasives and composite materials through special processes and formulas. They can be used for special-shaped processing of stone, ceramics, concrete and other materials. There is no need to add water during use, and it is not easy to dye. It can achieve the polishing effect of a water polishing pad. It has great advantages in saving water resources. It is being widely used in stone grinding and renovation projects in some special environments.

Dry polishing pad characteristics

1. Adopt the latest patent formula

2. It can achieve the polishing effect of water polishing pad

3. No scratches or color left on the stone after grinding and polishing (not easy to stain)

Use of dry polishing pad

1. The weight of the marble grinder is the key point, and only 150KG or more can be used for real leveling and grinding. If it is a small stone grinder with insufficient weight, there will be obvious waves, which is only suitable for small area or primary grinding or crystal surface For processing purposes.

2. When the marble grinder is grinding, if the water consumption is not well controlled, it is easy to induce the moisture reversal of the cement mortar at the bottom of the stone; the rise of calcium hydroxide white bloom.

3. In the polishing step, try to use weak acid or neutral stone polishing powder. The acidic polishing powder will burn the surface of the marble if it is too acid. The cheating method of not cleaning the residue after polishing will also erode and expand the lines and holes, which will cause many injuries. The sequelae of the hole, and cause annoying problems such as stone yellowing.

Polishing pad

The polishing pad is also called soft polishing pad. It is a flexible processing tool made of diamond as abrasive and combined with composite materials. The back is glued with Velcro cloth, which is fastened on the joint of the grinder for grinding. , Ceramics, glass, floor tiles and other materials for special-shaped processing, suitable for stone polishing, line chamfering, curved board and special-shaped stone processing, and can also be used for marble, coagulation, cement floors, terrazzo, glass-ceramics, artificial stones, floor tiles , Special-shaped processing, repair and renovation of glazed tiles and vitrified tiles.

Characteristics of polishing pad

It has strong grinding power, good durability, good softness, clarity and gloss. It is an ideal stone grinding tool. The whole process is divided into four stages: rough grinding, fine grinding, fine grinding and polishing. The processed stone , The gloss is over 90°.

Use of polishing pad

The polishing pad is suitable for portable electric or pneumatic grinders, and then the joint is connected, the power is 750-1500W, and the number of revolutions is 2000-10000. When working, apply a certain pressure to the machine while running water on the surface of the stone to be polished back and forth 4-5 times, then you can replace the finer polishing pad. Many people are accustomed to water polishing pads, because the water polishing pads are polished deeper, they are not prone to scratches, and there is no dust. Dry grinding is relatively shallow, and the amount of dust is relatively large, and scratches are easier to appear.
