Diamond polishing pad available range, use and maintenance methods

Diamond polishing pads may not directly touch us in life, but many of the stones we use, such as tiles, marbles, etc., are all made by diamond polishing pads, forming a particularly beautiful form to present to us.

Diamond polishing pad, also known as diamond soft-grinding pad, is a flexible processing tool made of diamond as an abrasive and combined with composite material. The back is affixed with Velcro cloth and fastened to the joint of the mill.
It can be used for grinding, and can be used for stone, ceramic, glass, floor tile and other materials. It is suitable for stone polishing, line chamfering, curved plate and special-shaped stone processing. It can also be used for marble, coagulation, cement floor, terrazzo, Shaped processing, repair and refurbishment of glass-ceramics, artificial stone, floor tiles, glazed tiles and vitrified tiles.

The diamond polishing pad has strong grinding force, good durability, good softness, good definition, good gloss, no scratches on the stone after grinding and polishing, and color left (not easy to dye), high wear resistance and long service life. 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 has a gloss of more than 90°.

Diamond polishing pad available range

Diamond polishing pad is one of the most commonly used grinding blades, because polishing pads of different sizes can be selected according to different grinding materials, which can be used for grinding such as fine grinding, rough grinding and polishing, and can also be used according to different needs. And with the habit of matching different refurbished machines, according to different grinding materials and grinding methods to carry out the corresponding processing, and finally achieve the desired effect. Because the diamond polishing pad has a relatively complete grain size and good flexibility, it is more convenient to use in the processing of special-shaped stone such as marble and granite.

1. It is used for stone processing such as artificial stone, granite and marble. It has complete standard grain size and good flexibility. It is handy for line, chamfer, curved plate and special-shaped stone processing. It has various shapes and specifications. Various grain size numbers are easy to distinguish. Tianbang diamond polishing pad can be flexibly matched with various hand grinders according to needs and habits.

2. It can be used for the treatment and renovation of various floors and steps after laying granite, marble and artificial stone plates. It can be flexibly matched with various hand grinders or refurbished machines according to needs and habits.

3. For the grinding and polishing of ceramic tiles, the tile manufacturer is equipped with manual, automatic full-throwing machine and semi-polishing machine for the full-throwing and semi-polishing treatment of microcrystalline bricks, glazed tiles and antique bricks. The brightness of the smooth surface can reach more than 90; it can be used for ground treatment and refurbishment of microcrystalline bricks and various ceramic tiles.

Marble polishing pad polishing process

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 crystal surface of the marble disappear, what method can be used to make the marble crystal surface Re-glowing? Generally in this case, we need to polish the marble to re-gloss the crystal face of the marble.

Then, when we polished the marble, we prepared some tools before polishing, and prepared terrazzo, marble polishing machine, diamond disc, polishing powder, stone crystal machine and so on.

Marble polishing process

1. Before performing the marble polishing work, first check the shape of the marble used to see if the decorated marble material conforms to the shape of the processing sheet, and then the polishing and polishing process of the marble, first of all, the marble For the place to be glued, it is necessary to wait until the glue is processed before polishing and polishing.

2. The first is to make a single-piece drawing line for rough grinding, usually it is to leave it 0.5MM fine grinding, water mill is also the same; after completion, it is splicing, mainly to match the polished and polished lines, and then based on The color of the surface of the line is correspondingly adjusted, so as to ensure the color of the marble surface and the good pattern effect. After the line water mill 500#, the number is first unified according to the requirements of the installation drawing, and then the polishing is disassembled. This will not cause the polished and polished lines to be concave and convex at the interface.

3. When there is a misalignment at the interface, the grinding of the transition section should be extended, the longer the better, and the straightness should be checked by the ruler during the grinding; the finished polishing line can be shipped after passing the quality inspection.

4. After the sanding is completed, use the water absorbing 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, use a washing machine with a scouring pad, spray the syrup with the same amount of water on the ground, start grinding, and make the crystal surface material on the stone surface under the action of heat energy. The surface effect formed after crystallization.

6. Overall ground maintenance treatment: If the stone with large voids is to be coated with marble protective agent, re-polishing once to increase the hardness of the crystal surface of the entire ground.

Generally speaking, the above steps can basically treat the marble surface well, but sometimes we encounter artificial stone like jazz white and resin. After doing it, 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.

Marble polishing precautions

When polishing marble, we use different polishing and polishing processes according to the type of marble, and the polishing process of the flat plate is different from the polishing process of the arc panel. We should pay attention to the following points when polishing and polishing.

1. When polishing and polishing, each abrasive or abrasive sheet should be carefully inspected and polished to the polished surface after grinding and polishing. After the grinding, the latter should cover up the traces produced by the previous abrasive.

2. Polishing and polishing should pay attention to the control of the amount of water, the lack of water is easy to cause the surface to burn.

3. When polishing and polishing, try to lengthen along the direction of the line, as long as possible, so as to avoid the generation of ripples.

4. The speed of polishing is faster.

5. Processing large quantities of lines polished or polished is better to use a forming knife, this can reduce the amount of rough grinding work, and ensure that the line after rough grinding of good quality, shape consistency.

What are the renovation procedures for marble polishing pads?

As more and more stone is applied to the decoration project and enters people’s daily life and work, people put forward higher requirements for the decorative effect of the stone. “Stone needs nursing” is increasingly accepted by people, and stone conservation has become an important part of the process of building decorative stone.

First, marble polishing pad renovation

Renovation of marble polishing pad is to renovate the marble floor, wall (or exterior wall), countertop, column and other marble plates without any seams, pollution, weathering, holes, no light, etc. Nursing machines, tools, etc. are cleaned, polished, and polished to restore the same luminosity as before the initial installation and to make the marble surface more visible.

The refurbished marble polishing pad has the following four effects:

1. Increased hardness: After treatment, the surface is not dusty, wear-resistant and scratch-resistant, and prolongs the service life of the stone floor.

2, mirror effect: the surface of the terrazzo can reach the same luster of natural stone, and the finish is high. The luminosity can reach 105°.

3, good anti-fouling: corrosion resistance, oil, water, anti-seepage, anti-fouling, water absorption is less than 0.5%.

4, easy maintenance: daily cleaning, maintenance is easy, greatly reducing the cost of cleaning and maintenance in the later period, daily use only dust push with electrostatic vacuum dust, regular neutral detergent cleaning or stone care solution polishing marble board.

Second, the marble polishing pad renovation step procedure

Natural marble, also known as marble, is mainly composed of calcium carbonate and magnesium, sodium, silicon, etc. The hardness of the friction type is about 4 or 5, which is soft. It is less resistant to weathering, so it is easy to lose luster on the worn surface. We can choose to carry out light, medium and deep stone renovation according to the degree of stone surface wear.
The equipment, accessories and consumables required for marble renovation are: ordinary weighting machine, 4 inch diamond water-grinding disc, 17-inch refurbished disc, water absorbing machine, signboard, watering can, glass scraping, water wiper and bucket.

1. Marble polishing pad is lightly refurbished

The surface of the stone is slightly scratched and can be refurbished with a mild refurbishment process. If there is old wax on the ground, first wax, then use 800# diamond water grinding disc and clean water for 10 minutes. Note: add water in the grinding process to keep the ground moist, and use suction machine to absorb the sewage to prevent the second pollution of sewage. ground. Then change 1500#, 3000# polished sheet, diamond water-grinding sheet, and polish one by one by the above method. After the refurbishment process is completed, the water on the surface of the stone is washed with water and the surface of the stone is gently refurbished.

2. Marble polishing pad moderately refurbished

When the surface of the stone loses its luster, it can not reflect the object at all, but it has no deep scratches. It can be refurbished by a medium refurbishment process. Polished pieces of 200#, 400#, 800#, 1500#, 3000# and diamond water-grinding pieces were polished one by one. The grinding method and precautions were consistent with the above.

3. Marble polishing pad depth renovation

When the surface of the stone is holed, weathered, severely corroded, completely tarnished and deeply scratched, it can be refurbished by a deep refurbishment process. Before renovating, the holes should be repaired as follows: first clean the dirt in the holes, then dry the stone, and use imported epoxy resin or unsaturated resin glue according to the color and reflective characteristics of the original stone. After the coloring, the repair was carried out, and the weighting machine, the new plate and the 50#, 150#, 200#, 400#, 800#, 1500#, 3000# polished diamond water-milling pieces were used for one-by-one polishing. The grinding method and precautions are consistent with the mild renovation.

If marble crystal hard powder is used for hard treatment of stone crystal, in the process of refurbishing, after grinding with 800# diamond water grinding sheet, the crystal hard powder can be directly used for crystal hard treatment, and the surface of the treated stone is as bright as new.

Concrete polishing pad use method

The concrete polishing pad is specially formulated and used for the grinding and polishing treatment and renovation of concrete floors, warehouses, parking lots and other concrete floors, cement self-leveling floors, various aggregate hardener floors and liquid hardener floors.

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 the water suction machine to absorb the surface water, apply the interface agent, use the repair materials that meet the requirements to repair and maintain according to the specifications;

3, leveling: use TFP series concrete floor 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 polishing pad. If the hardness of the ground after the osmosis hardening meets the construction requirements, sanding will not occur during fine grinding;

7, fine grinding (rough polishing): use 500#-1500# series concrete polishing pad;

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, penetration. Varnishing: use concrete permeable brightener or similar products, pay attention to different processing techniques of different products;

10, fine polishing: use concrete polishing pad 3000# (select 1-2 particle sizes as needed).
The new ground infiltration treatment suggests that the infiltration treatment is carried out 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 grain size polishing pad, available for selection of granularity number including 30#, 50#, 100#, 150#, 200#, 300#, 400#, 500#, 600#, 800# , 1000#, 1500#, 2000#, 3000#, etc.

3. Dry grinding, water mill using different formulations of polishing pad, water mill can reduce on-site ash and improve efficiency. The granularity numbers are: 30#, 50#, 150#, 300#, 500#, 1000#, 2000#, 3000#, according to the actual situation, the jump level can be selected, the use effect and the ground hardness, flatness, and the granularity number selected by the polishing pad grinding time, experience of use. In the whole process, rough grinding, fine grinding is more uniform and more thorough, and the fine and smooth light will be saved and polished in a more efficient way.

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

Introduction of polishing polishing technology for polishing pad

When many people renovate their homes, they usually renovate the floor of their homes and renovate the old tiles into new ones. Sometimes, this is not necessary. You can achieve this effect with a simpler method. Then, in detail, we will introduce the polishing and polishing technology of the polishing pad in detail, so that you can have a new look in the home without replacing the new ceramic tile.

1. The traditional construction technology has caused the polishing pad to be very rough and filthy. Even if it has not been delivered, it will be dirty, and it will cause serious obstacles to daily hygiene termite control. However, as time went by, there were very prominent problems in actual use: the polishing pad was weathered, abraded, stained, and dull. China has used nearly 5 billion square meters of polishing pads in buildings. How the floor refurbishment film restores the weathered and abraded polishing pad to its original beauty and beauty is an increasingly urgent problem to be solved in the building decoration industry.

2. Facing the weathering and abrasion of the polishing pad, the only way at home and abroad is to remove the dirt on the surface of the stone and apply a layer of wax. Many people think that after waxing, they can keep the tiles transparent. In fact, this method can only temporarily keep the tiles bright and bright, and the duration of the tiles is only one week, so this method is not feasible.

3. In order to re-form the protective film on the polishing pad floor, it is necessary to polish the polishing pad floor. The weathered, abraded aging layer of the polishing pad surface can be shaved with a polishing pad ground grinding machine to expose the fresh layer and then mechanically maintained.

After understanding the above knowledge, we know that after polishing the polishing pad polishing technology, I feel that this technology is quite good, but the effect is not very big, and the maintenance time is not very long, so the technology still needs to be improved. However, this is a very practical and simple and easy way to operate the ground.

How to choose polishing pad for concrete floor construction

The selection and use of polishing pads are very regular. The ground leveling and rough grinding should use diamond grinding discs or concrete thick grinding discs. Dry grinding is more material saving than water grinding, but the water grinding treatment will make the ground more uniform and fine. Wait, then when choosing a polishing pad, how should I choose? What factors will affect our choice? I will analyze it carefully with you today.

Commonly used concrete polishing pads mainly include the following: Polycrystalline diamond polishing pad: used to remove epoxy coating, which is needed 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 a diamond resin polishing pad with a thickness of 5mm or more, used for concrete floor leveling, rough grinding, fine grinding, fine grinding and polishing;

Thin concrete polishing pad: usually refers to a diamond resin polishing pad with a thickness of 5mm or less, used for rough grinding, fine grinding, fine grinding and polishing of concrete floors;

Concrete polishing pad: usually made of man-made fiber, wool or other animal hair, and some products are also added with abrasive and polishing accessories for polishing the concrete floor; how to choose and use such a variety of polishing pads Use it?

Flatness of the ground

Manually screed the leveling ground or the old ground that is loose or damaged. It needs to level or remove the loose surface layer. It needs to use a high-power grinding machine, choose a concrete diamond polishing pad and other grinding force, suitable for leveling polishing. pad. 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.

Ground hardness

The concrete used in the design and construction of the concrete floor is indicated by the number, which is C20, C25, C30, etc., which we usually talk about. In normal cases, the higher the number, the better the strength and hardness of the concrete, but due to various The influence of factors, the number of concrete and the hardness of the ground are often not corresponding. 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 use some substitutes instead of the Mohs hardness tester to understand the hardness of the ground: the hardness of the scratches and scratches can be less than 5 with nails and keys. Otherwise the hardness is greater than 5.

Grinder weight and speed

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 much weight is very efficient, but it often leads to excessive grinding and increases. 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.

Type and size of polishing pad

The most commonly used abrasives for floor treatment are PCD polishing pads, metal-based polishing pads and resin-based polishing pads. PCD polishing pads are used to remove thick coatings on the floor surface. Metal-based polishing pads are used for floor surface pretreatment and rough grinding. Resin-based polishing pads are used for rough grinding, fine grinding, fine grinding and polishing. Particle size refers to the size of the diamond particles contained in the abrasive tool. The lower the number, the larger the particle size.

The PCD polishing pad is not granular, but it is directional, so pay special attention to it when using it.

Metal polishing pads are usually divided into several numbers such as 30#, 50#, 100#, 200#, etc. Which granularity number should be determined according to the ground conditions, such as poor ground flatness or loose surface, may need to use 30# The metal polishing pad removes the loose surface to level the ground. The ground that needs to be sanded or grinded usually requires a 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 coarse grinding, fine grinding, fine grinding and polishing; resin polishing pad has hard polishing pad and soft The difference between the polishing pad and the hard polishing pad is better. It is more suitable for medium and large floor grinding machines. The soft polishing pad has better polishing effect and is suitable for various types of floor grinding machines.

How to use diamond polishing pad

Diamond water (soft) grinding disc has a uniform specification of granular color and good flexibility. It is widely used in the processing of granite, marble, artificial stone and other lines, chamfers, countertops, curved plates and special-shaped stone. The shape and specification are optional, and the various grain sizes are distinguished by different colors. According to the needs and habits of the guests, various hand grinders, ground stone refurbished machines and ceramic polishing machines can be used flexibly.

As we all know, the diamond polishing pad can restore the ground to the luster, so how to use it correctly?

1. Thoroughly clean the ground. Use the knives to remove the concrete slurry from the stone gap and then thoroughly remove the dust with a brush, vacuum cleaner, etc. 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. Firstly, the original damaged surface is repaired with marble glue close to the stone color. Then use a special stone slitting machine to re-align the slits of the original stone installation to make the width of the gap uniform, 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. Finish the first pass of the grinding, re-cast the marble glue, the caulking, and continue the second grinding. Then use the stone refurbished machine with the diamond polishing pad from coarse to fine. A total of seven grinding and polishing finishes are required. The whole is flat and 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. Grind it with a marble polishing machine. 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. Make the crystal surface material crystal on the surface of the stone. The surface effect formed after the formation.

6, the overall ground maintenance treatment: If the stone with a large gap is to be treated with a marble protective agent, re-grinding once to increase the hardness of the crystal surface of the entire ground.

7. Ground cleaning and maintenance: When the surface of the stone is crystallized, use a vacuum cleaner to absorb the residue and moisture on the ground. Finally, polish the surface with a polishing pad to make the whole surface completely dry. Bright as a mirror. If local damage is possible, local maintenance is possible. Construction can be done at any time.

The best diamond polishing pad manufacturers remind you that it is not enough to use diamond polishing pads. There are still several requirements to be aware of during use:

1. When working, the workpiece should be fixed, the profile positioning should conform to the direction of the knife, so as to avoid abnormal cutting, do not apply side pressure or curve cutting, the feed should be smooth, avoid the blade impact contact with the workpiece, resulting in damage to the diamond polishing pad. Or the workpiece flies out and an accident occurs.

2. When working, if the sound and vibration are abnormal, the cutting surface is rough, or the odor is generated, the operation must be terminated immediately, and the fault should be checked in time to eliminate the accident to avoid accidents.

3. When starting cutting and stopping cutting, do not feed the knife too fast to avoid broken teeth and damage.

4. If cutting aluminum alloy or other metal, use a special cooling lubricant to prevent the diamond polishing pad from overheating, causing paste, and other damage, which affects the cutting quality.

5. Equipment chip flute and slag suction device ensure smooth flow to prevent slag from forming into blocks, affecting production and safety.

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

Resin polishing pad cleaning method description

Resin polishing pads are generally classified into ordinary resin grinding discs and super hard resin grinding wheels according to abrasive materials. Ordinary resin grinding wheel is a grinding wheel with white fused alumina, brown fused alumina and silicon carbide as the main grinding components. The super-hard resin grinding wheel is a grinding wheel with diamond or CBN as the main grinding part.

The polishing wheel must be carefully inspected and identified before installation. The steps to check the authentication are as follows:

1. Check that the slope of the grinding wheel is correct and that it meets the performance, shape and dimensions of all selected grinding wheels.

2. Check and determine the appearance of the grinding wheel. Look at the wheel for damage (or cracks) with your eyes. Do not use a grinding wheel that is damaged (or cracked). In addition, the ends of the grinding wheel are required to be flat and must be free of significant skew.

3. Check and identify the internal cracks in the grinding wheel. Use a hand-held grinding wheel and hit the wheel with a wooden hammer to hear the sound. The broken wheel made a crisp sound, and the broken wheel was hoarse and unusable.

Resin polishing pad cleaning method

In the production process, diamond wheels are used to polish the belt. Typically, the grinding wheel is removed for cleaning after 5-7 days of operation. (The above rubber crumb is polished and adhered to the surface of corundum after high temperature friction, which is difficult to clean)

Now we soak it in acetone for 2 hours and then clean it with an imported cleaner. The effect is very good, but it is not environmentally friendly and does not save energy.

Resin polishing pad cleaning requirements

1, to be environmentally friendly, does not contain ketones, can not be halogenated hydrocarbons.

2, can not damage the diamond wheel

How to choose the size of concrete polishing pad

Many people are accustomed to using concrete polishing pads because the concrete polishing pads are deeper, are less prone to scratches, and are free of dust.

First: leveling

1. Surface treatment of old floor with good flatness: use 50#-200# concrete resin grinding disc according to ground hardness

2. Remove the loose surface layer of the old floor: Use 30#-100# resin grinding piece or 30#-100# metal grinding piece to easily remove the loose surface layer of the floor. It is recommended to use the medium and large floor grinding machine.

3. The surface treatment of the flatness with poor flatness: firstly leveling with 50# metal grinding disc, then rough grinding with 100# concrete resin grinding sheet, and finally grinding with 200# concrete resin.

4. Surface treatment of large-area repairing floor: It is recommended to use 50# metal grinding disc to grind and level before the ground is completely cured. After curing, use 100# concrete resin grinding disc to roughen and level, and accurately grasp the grinding timing to make the floor treatment. It’s simple and easy.

Second: rough grinding

1. terrazzo floor, concrete colored sand floor, uniform dry sand hardening agent floor: According to the hardness of the floor, the concrete resin grinding plate with particle size 30#-200# is coarsely ground, and the concrete resin grinding machine with particle size 200#-500# is used. The medium and large grinding machines for the sheet can improve the grinding efficiency and make the ground flatness better.

2. After the ground leveling treatment, select the high-granularity number (100#-500#) concrete dry grinding sheet coarse grinding resin polishing pad polishing pad

Third: fine grinding

1. Newly made aggregate hardener floor to maintain the surface effect of the original slurry: select the above-mentioned 500-size resin grinding plate or a small-sized grinding machine, and select the grinding piece with the corresponding grain size according to the surface hardness and curing time of the floor. A new floor with good mechanical light is easy to make a uniform surface effect.

2. Ground after rough grinding: Generally, the concrete grinding disc with the above-mentioned particle size of 500-1000 is selected for fine grinding treatment, and the matching medium and large grinding machine can be used to improve the grinding efficiency and make the ground flatness better.

Different concrete resin grinding discs in different situations

1. Polishing treatment: The grinding sheet suitable for the ground polishing treatment includes: a concrete resin polishing sheet polishing sheet having a particle size of 1000#-3000#. It is usually installed on a refurbished machine or a floor grinder. The polishing effect is related to the hardness, flatness and pre-treatment effect of the ground. The dry throwing effect is better.

2. Crystal surface treatment: The concrete polishing sheet has three granular numbers of 1000# 2000#3000#, which are used for polishing after the fine grinding of the floor. When using, choose a size number to polish according to the requirements. The most commonly used size number is 2000#, which is usually used on the floor grinder or refurbished machine. The wet throwing effect is better than the dry throwing light. It is recommended to use concrete brightener for floor surface treatment. After spraying the Tektron concrete brightener, using 2000# concrete polishing sheet, it is easy to bring a long-lasting and charming mirror effect.

Grinding life and grinding effect will be affected by various factors, including ground hardness, grinder weight, counterweight, speed, whether water and water, grinding type, quantity, particle size, grinding time and experience. It can be used with a variety of refurbished machines and grinders. It is suitable for medium and large grinding machines to improve the grinding efficiency and make the ground flatness better. Use concrete dry grinding without water grinding, otherwise use concrete polishing pad.

5. When starting cutting and stopping cutting, do not feed the knife too fast to avoid broken teeth and damage.

6. If cutting aluminum alloy or other metal, use a special cooling lubricant to overheat the waterproof sheet, produce paste, and other damage, affecting the cutting quality.

7. The equipment chip flute and slag suction device ensure smooth flow to prevent slag from forming into blocks, which affects production and safety.

Diamond polishing pad use method

The diamond polishing pad is suitable for portable electric or pneumatic mills, and then the joint is connected, the power is 750-1500W, and the number of revolutions is 2000-10000 rpm.

When working, the water is applied to the machine by a certain pressure on the surface of the stone to be polished 4-5 times, and the finer number one grinding piece can be replaced. Many people are accustomed to using water to grind tablets, because the water-grinding pieces are deeper, they are not prone to scratches and there is no dust. The dry grinding is relatively shallow, the dust is relatively large, and the scratches are more likely to occur.

A single water mill can’t satisfy all the different floors, especially the ground with extremely bad strength and serious sanding. This kind of ground can’t be blistered. If the water mill is afraid to see the loess, it doesn’t matter, you can choose dry grinding and grinding. As long as the ground is cleaned and no sand is brought into the chassis, there will be no scratches.

Diamond polishing pad use precautions

Diamond polishing pads are often used in angle grinders and floor refurbished machines. They are mainly polished and polished for various types of granite, marble and artificial stone. Of course, they are also suitable for renovation of stone on the ground, but in the process of grinding. It is necessary to add an appropriate amount of water for cooling. The main usage precautions can be divided into the following points:

First, it is often used to polish the inner arc, corner and outer arc of various special-shaped stone such as granite, concrete floor and marble;

Second, the sharpness of the diamond polishing pad is better, and the grinding speed is also fast, not only the luminosity is high and the glazing is fast;

Third, the degree of wear resistance is very high, and the service life is much longer, which is the comprehensive use performance and cost performance;

Fourth, if you are using a portable water polishing machine, remember that the entire speed of the motor can not be ≤ 4500 rpm;

Fifth, it is best to use different colors of stone. When choosing soft-grinding pieces, you must choose the color and stone close to each other;

Sixth, when we use soft grinding tablets, the correct way is to directly attach the surface with velvet to the joint, not only convenient but also very fast.
