Marble international collectively known as marble stone, with its natural and simple texture, bright color, is widely used in building interior walls, because the marble material is relatively loose, soft texture water absorption is relatively high. There are more joint lines, so in the process of processing, transportation, installation and use, it is easy to appear a variety of pollution and warping deformation, 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 finishing, the method 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.
Let's talk about the construction process of refurbished grinding treatment and crystallization polishing treatment first:
First of all, do waterproof before the renovation and grinding, the purpose is to make the stone as little water absorption as possible, so as to reduce the stone water absorption law, and then do waterproof after 300#, because the grinding will cause the waterproof effect to be reduced or disappeared, it is best to do waterproof again after 800# if the conditions allow.
Encounter relatively loose stone, such as white sand beige, sandstone, tropical rain forest, wood grain stone, etc., to first use a high content of sealing curing agent (such as superhard inorganic paint, content of more than 40% silicone sealant) for pre-treatment, so that the stone in the filling loose at the same time also hardened the material.
1, rough grinding: Use 50#, 150#, 300#, 500# steel resin hard grinding block (rough grinding do not use soft water grinding, easy to appear waves, affect the flatness) rough grinding to the water slightly larger but remember not too much, after each grinding to thoroughly absorb water, check whether the deep cut abrasive path is worn off with 50# grinding, and so on, Machine toe grinding, rough grinding accounted for 45% of the overall grinding time, is to ensure the completion of the project quality acceptance of the key link.
2, fine grinding: The use of 800#, 1000#, 2000# steel resin soft grinding, fine grinding accounted for 35% of the overall grinding time, fine grinding to 800# after the initial light appeared, fine grinding to 2000# after the gloss of up to 50 degrees.
3, fine grinding: The use of 3000# steel resin soft water grinding plate to spray A2 grinding, ion exchange, fine grinding accounted for 20% of the overall grinding time, after grinding the gloss is very high, the surface density of the marble stone is improved, to lay a solid foundation for the polishing agent (NO2+Q5 mirror repair agent) to enhance the adhesion of the polishing material.
4, polishing: The use of power above 2HP, speed 175-- 210 RPM, weight 45-70 kg crystal face machine, animal hair content of 70% of the animal hair mat, 3M mat, nano mat, with marble mirror cream NO2, 2X mirror lock knife into milk Q5 polishing, polishing marble surface gloss can reach at least 90-100 degrees above.
5, encountered more difficult to make transparent stone, such as jazz white, resin artificial stone, if the above method is still not bright enough, then spray A2 again with 3000# grinding to dry, and then repeat with nano pad, with marble mirror cream NO2, 2X mirror lock knife into milk Q5 polishing and grinding, Nano inorganic polymer copolymer formed crystalline layer, glassy, water bright effect will be able to come out. It has high hardness, wear resistance, transparency, water resistance, anti-fouling, anti-slip and other functions
