About marble polishing
The marble we now see is very smooth and very beautiful. In fact, although the material is natural for marble, it has been processed through many processes to form its current appearance.
In the marble furniture production process, marble polishing is the former process flow of stone care crystal surface treatment, and it is the most important process flow in stone care.
What about marble polishing ? How is its price? Is polishing and waxing the same? Let's briefly introduce Xiao Qi.
Nowadays many companies are engaged in polishing work, and there are also many machines specializing in polishing. Polishing is a necessary process for marble processing. The price of marble polishing is also one of the focuses of people's attention. For marble processing, there are mainly the following steps. After these steps, marble will have a better luster.
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.
Every time the area of ​​the crystal surface sprayer is 2m2, it needs to be polished step by step. It can't stop. Whenever the crystal surface agent is ground by the ground wiping machine, the stone should be shut down immediately after the glass shines, otherwise, the brightness will be excessive. Thermal damage caused by friction becomes counterproductive, especially with white stone. The price of marble crystal surface treatment is that the price of each place is different, about 200-300 yuan, and each area will be a bit different.
1, the essential difference
a. Marble grinding block polishing is a necessary process flow for the 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 conjunction with the mechanical grinding discs' pressure, high-speed grinding force, frictional heat energy, and the effect of water on the relatively smooth marble surface for physical and chemical cooperation. , thus forming a new bright crystal layer. This crystal layer has super bright, clear luminosity. Brightness up to 90-100 degrees. This crystal layer is a modified crystal layer of the stone surface (1-2 mm thick).
b. 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 the market and existence. Its essence is a thin coating of acrylic resin and emulsion polymer covered on the surface of a new stone (polish) plate, which is what we often call 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.
c. The grinding block polishing process before the marble treatment crystal face processing 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.
d. 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.
2, the difference between appearances
The grinding and polishing of the marble block is the prelude to the crystal face care stone care. After the polishing, the luminosity is high, the clarity is high, and the abrasion resistance, the step resistance, and the scratching are not easy. It is the true embodiment and value extension of the stone use function.
The brightness of polished stone 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 it turns yellow to make the nature of the stone lower.
3, the difference between extension and operation
After the polishing of the crystal layer and the crystal layer of the stone grinding block, the pores are not completely closed after the continuous care (commonly known as crystal face care), and the stone can still breathe inside and out, and the stone is not easy to be damaged. At the same time have a certain degree of waterproof, anti-fouling effect. After waxing and polishing the marble, the pores of the stone are completely closed, and the stone cannot breathe inside and out, so the stone is easy to produce lesions.
The continuous care of the crystal layer and the crystal layer after the polishing of the stone 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.
After waxing and polishing marble, 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.
Marble grinding block polishing is a necessary process flow for the stone crystal face processing or stone processing. Physical and chemical cooperation is carried out to form a new bright crystal layer, and the wax layer on the marble waxing surface is attached to the surface of the stone, a layer of resin film, and there is no compound reaction with the stone itself. So the price of marble polishing is higher than the cost of waxing. And polishing can be kept longer.
In fact, for this marble material, to use and make furniture, polishing is a necessary step. No matter how the marble polishing price is, it must be polished to a brightness of 90-100 degrees. This kind of marble is more durable. . Polishing is more advantageous than waxing, so polishing is now becoming a trend and mainstream for marble processing.
It is because of the steps such as marble polishing that make our marble furniture beautiful. It can be said that this is a very important step.
