What are the production processes of marble?



Marble International, collectively known as Marble, is widely used in architectural interior walls due to its natural and quaint texture and bright color. Because the marble material is relatively loose, the texture is relatively soft and the water absorption rate is relatively high. There are many joint lines, so various pollution and warping deformation, easy loss of light and other phenomena occur during processing, transportation, installation and use, which affects the decorative effect. Therefore, the care of marble is also a compulsory course for 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 processing. 3: Cleaning protection treatment. 4: Crystal polishing treatment. 5: Seamless filling processing, etc.

Construction process of marble grinding and crystal polishing:

First of all, before the refurbishment and polishing, the purpose is to make the stone as little as possible to absorb water, so as to reduce the water absorption rate of the stone. After 300#, it is waterproof. At that time, the effect of waterproofing will be reduced or disappeared due to the grinding. In case of the best 800#, do another waterproofing.

In the case of relatively loose stone, such as white sand beige, sandstone, tropical rain forest, wood grain, etc., first use high-content sealing curing agent (such as super-hard inorganic coating, 40% silicone resin sealant) for pre-treatment. The stone is hardened while filling the loose material.

1. Rough grinding: use 50#, 150#, 300#, 500# diamond resin hard grinding block (rough grinding, do not use soft water grinding disc for grinding, easy to appear wave, affect flatness) coarse grinding water supply slightly larger But remember not too much, each piece of grinding should be thoroughly absorbed after grinding, check whether the deep scribe left by the cutting abrasive is worn off with 50# grinding, and so on, the machine is grinding, the coarse grinding accounts for the overall grinding. 45% of the time is the key link to ensure the quality of project completion.

2, fine grinding: use 800 #, 1000 #, 2000 # diamond resin soft water grinding tablets, fine grinding accounted for 35% of the overall time, fine grinding to 800 # after the emergence of the first light, fine grinding to 2000 # after the gloss Up to 50 degrees.

3, fine grinding: using 3000# diamond resin soft water grinding sheet spray A2 grinding, ion exchange, fine grinding accounted for 20% of the overall grinding time, the gloss after polishing is very high, the surface density of marble stone is improved, The polishing agent (NO2+Q5 Mirror Repair) lays a solid foundation and enhances the adhesion of the polishing material.

4, polishing: use power 2HP or more, speed 175-210 rev / min, weight 45-70 kg crystal machine, animal hair content 70% animal hair pad, 3M pad, nano pad, with marble mirror complex cream NO2 2X mirror lock bright knife into the milk Q5 for polishing, after polishing, the surface gloss of the marble can reach at least 90-100 degrees.

5, encounter more difficult to make translucent stone, such as jazz white, resin artificial stone, if the above method is still not enough to light, then spray A2 with 3000# to dry, then repeat with nano pad With the marble mirror complex cream NO2, 2X mirror lock bright knife into the milk Q5 for polishing, nano-inorganic polymer copolymer to form a crystalline layer, glassy, water bright effect will certainly come out. With high hardness, wear resistance, transparency, resistance to water, dirt, slip, etc.
