Do you know how to polish marble ? Marble grinding block polishing is a necessary process flow for the stone crystal face processing or stone processing. The main principle is the use of pressed abrasive blocks synthesized from inorganic acids, metal oxides, etc., in combination with the mechanical disc pressure, high-speed grinding force, and frictional heat energy. The grinding block polishing process before the marble treatment crystal surface treatment is the physical and chemical cooperation process between the stone surface layer and the chemical substance. If you are not very familiar with how to polish marble, you may wish to follow me to learn about it!
How to polish marble
Marble polishing is the last process of stone care crystal processing or the last process of stone processing. It is one of the most important technological processes of stone care today. It is different from the marble washing and waxing polishing of the traditional company's business scope.
The advantages of marble polishing:
1. The polished stone surface shines brightly and is highly layered.
2, lower costs, time, labor.
3, to prevent the infiltration of the material into the inner layer of stone, enhance the wear resistance of the stone, non-slip and other effects, use the least cost to achieve the maximum maintenance effect.
4. There will be no scratches on the stone surface caused by the use of steel wool.
5, will not make the stone surface discoloration or leave yellow embroidered rust.
Marble polishing process
Marble International collectively known as marble, with its natural and ancient texture, bright color and bright, is widely used in the interior walls of the building, due to the relatively loose marble material, texture, relatively soft water absorption is relatively high. There are many joints, so the process of transportation, installation and use of the process is prone to various pollution and warpage, easy to lose light and other phenomena, affecting the decorative effect, so the care of marble is also a required course in the nursing industry. To compare and analyze the condition of marble finishes, the methods of care can be divided into:
1: Refurbished grinding treatment. 2: Local drop handling. 3: Cleaning protection treatment. 4: Crystal polishing treatment. 5: seamlessly fill the processing.
Refurbishing grinding, crystal polishing processing construction process:
First, waterproof before refurbishing, the purpose is to make the stone as little as possible to absorb water, so as to reduce the stone water absorption law, and then do waterproof after 300#, then the abrasion effect will be reduced or disappear because of cutting, conditions permitting In the case of the best 800 # after a waterproof.
Stones that are relatively loose, such as white sand beige, sandstone, tropical rain forest, wood grain, etc., must be pre-treated with a high content of a sealing hardener (such as a superhard inorganic coating and a silicone resin sealant with a content of more than 40%). Makes the stone harden while filling the material.
1, coarse grinding: the use of 50 #, 150 #, 300 #, 500 # diamond hard resin grinding block (coarse grinding do not use soft water grinding for grinding, prone to waves, affect the flatness) coarse grinding water supply slightly larger But remember that not too much, each mill grinding to thoroughly absorb the water, check whether the deep scribe of the cut-off abrasive is worn with a 50# grinding wheel, and so on, the machine goes to the word grinding, coarse grinding accounts for the overall grinding 45% of the time is the key to ensuring the acceptance of the project completion quality.
2, fine grinding: the use of 800 #, 1000 #, 2000 # diamond resin soft water, fine grinding accounted for 35% of the overall grinding time, fine grinding to 800 # after the emergence of primary light, fine grinding to 2000 # after the gloss Up to 50 degrees.
3, fine grinding: use 3000# diamond resin soft water mill spray A2 grinding, ion exchange, fine grinding accounted for 20% of the overall grinding time, after polishing, gloss is increased very high, the surface density of marble stone is increased, The polishing agent (NO2+Q5 mirror repair agent) lays a solid foundation and enhances the adhesion of the polishing material.
4, polishing: the use of power above 2HP, speed 175 ---210 rev / min, weight 45-70 kg crystal face machine, animal hair content 70% of the animal hair pad, 3M pad, nano mat, with marble mirror complex Yan cream NO2, 2X mirror lock bright knife into the milk Q5 for polishing, polished marble surface gloss can reach at least 90-100 degrees.
5, encountered more difficult to do translucent stone, such as jazz white, resin artificial stone, if the above method is still not enough water, then spray again A2 with 3000# to dry, and then repeat the use of nano-mat , With marble mirror complex Yan Yan cream NO2, 2X mirror lock bright knife into the milk Q5 for polishing, nano-inorganic polymer copolymer to form a crystalline layer, was glassy, ​​shiny effect will be able to come out. Has a high hardness, wear resistance, transparency, anti-water, anti-pollution, anti-slip and so on.
The difference between marble polishing and waxing
Essential difference
1. Marble grinding block polishing is a necessary process flow for stone crystal face processing or stone processing. Its main principle is the use of pressed abrasive blocks synthesized from inorganic acids, metal oxides, etc., in combination with the pressure of mechanical grinding discs, high-speed grinding forces, and frictional thermal energy, and the effect of water on the relatively smooth marble surface for physical and chemical cooperation. As a result, a new bright crystal layer is formed. This crystal layer has a super bright, clear luminosity with a luminosity of 90-100 degrees. This crystal layer is a modified crystal layer of the stone surface (1-2 mm thick).
2. Marble cleaning is a prelude to marble waxing and polishing. Marble cleaning, waxing and polishing belong to the popular marble cleaning and maintenance protection measures in the early 1980s and 1990s. Today, they have lost the significance of market and existence. Its essence is a thin coating of a polymer of acrylic resin and emulsion covered on the surface of a new stone (polished plate), which is commonly known as water wax or floor wax. After a high-speed, low-pressure polishing machine with a fiber mat rubbing on the surface of the stone to make the resin coating a brighter process. Due to the product's renewal, special light waxes, paraffin polishes, etc. appeared later. This coating is similar to oil varnish on wood floors.
3. The polishing process of the grinding block before the marble treatment crystal surface treatment is the physical and chemical cooperation process between the stone surface layer and the chemical substance. The stone surface and the bottom layer are completely integrated into one whole, and there is no escape layer.
4. Marble Wax Polishing The wax layer above is attached to the stone surface, a layer of resin film, and there is no compound reaction with the stone itself. The wax layer can be gently scooped with a blade to cut the wax film off the stone surface.
Difference in appearance
1. The grinding and polishing of the marble block is the prelude to the stone treatment crystal surface treatment. After the stone care polishing, the luminosity is high and the clarity is high. The wear resistance, the step resistance, and the scratching are not easy. It is the true embodiment and value extension of the stone use function.
2. The luminosity of the stone after waxing and polishing is low, the luminosity is not clear, and it is very vague, it is not wearable, it is not water resistant, it is easy to scratch, and the oxidation turns yellow to reduce the essential image of the stone.
Difference between extension and operation
1. The continuous care of the crystal layer and crystal layer after the polishing stone block is polished (commonly known as crystal face care), the pores are not completely closed, the stone can still be breathable inside and out, and the stone is not easily affected. At the same time have a certain degree of waterproof, anti-fouling effect.
2. After the marble is waxed and polished, the pores of the stone are completely closed, and the stone cannot be breathed inside or out, so the stone is easy to produce lesions.
3. The continuous care of the crystal layer and crystal layer after the polishing of the stone grinding block is easy to operate, no cleaning agent is required to clean the ground, and the grinding block can be directly combined with water polishing and chemical dry grinding. Can always be polished and care, can be partially operated. There is no new contrast in the color of the stone surface.
4. After marble polishing, after a period of time, it is necessary to remove the old wax layer and use wax water. At the same time, large-area operation and construction are required, and no partial construction is allowed. After the partial construction, there is a color difference on the surface.
Practical significance
1. After the marble is polished by the polishing block, the luminosity can reach 90-100 degrees, which restores the luminosity of the stone factory and realizes the reproduction of the stone value. Crystal surface treatment can save time, labor, cost, and wear resistance. After waxing and polishing the marble, the surface brightness of the marble is reduced, the blur is not clear, and the functional value of the stone is reduced, which is not ornamental.
2. The difference between the above nature and appearance can be found: marble waxing and polishing must be eliminated and faded out of the market. Due to the advanced technological principles and methods of marble grinding and polishing crystal face care, it can make marble more ornamental and prolong its service life.
