The marble is good, how to polish the marble
Fine grinding: use 3000# diamond resin grinding grinding, soft water spraying A2 by ion exchange, grinding the total 20% grinding time, grinding after lifting high gloss surface, improve the density of Dali stone, as a polishing agent (NO2+Q5 mirror repair agent) to lay a solid foundation, enhanced the adhesion of polishing material.
Fine grinding: use 800#, 1000#, 2000# diamond resin soft grinding, fine grinding accounted for the overall research 35% time, fine grinding to 800# after the beginning of light, fine grinding to 2000# degrees up to 50 degrees after ze.
Coarse grinding: use 50#, 150#, 300#, 500# diamond hard resin grinding block (coarse grinding grinding grinding do not use soft water, prone to wave, affecting the flatness) to coarse grinding of older water but remember not too much, each end mill to thoroughly check water, leaving deep abrasive cutting whether the 50# mill scratch off, and so on, the machine go well shaped grinding, coarse grinding, grinding time is the total 45%, to ensure the completion of the project quality acceptance of the Guan Jian link.
In the first polishing before doing waterproof, the purpose is to make Dali stone water less as far as possible, so as to reduce the Dali stone water law, water again after 300#, at that time because the grinding will cause the waterproof effect is reduced or disappeared, the conditions allow the best 800# and then do a waterproof.First with a high content of sealing curing agent (such as super hard inorganic coating, the content of more than 40% silicone resin sealant) for the pre-treatment, so that the Dali stone to fill in the loose while hardening the material.
