Commonly known as the granite granite, mainly composed of quartz, mica, Mohs hardness value is about 6.5, to hard, long-term use and prone to natural weathering and abrasion, its performance characteristics off the mica. The stone surface pitting a small amount of indentation when pitting the growing granite surface brightness decline, lose their luster, when the hand-to-concavity, using the renovation to restore the stone luster.Granite, hard texture, so the surface is damaged, simply use the conservation of the chemical class of agents, abrasives and other conservation is difficult to achieve the desired result, the use of stone renovation agent by physical grinding methods, the effect is better than the simple chemical products refurbished grinding .
Granite renovation of the necessary equipment, accessories and supplies: stone refurbished agent, a full set of granite refurbished piece, 17-inch red pad, suction machines, signs, watering can, photometer, glass blowing to wash, wipe water and buckets.
Working procedures and construction methods:
1 posted notices at the job site, in order to prevent mud dirt splashed on the walls, the ground around the wall at the bottom of plastic transparent film and paste it. Adding water in the stone renovation tank, connect the power supply, various models of metal shut up disc, granite refurbished disc and adjust the equipment and the level of the ground, ready to work.Such as the ground is the old wax from the wax.
Metal shut up disc to use foul language, are in turn the album needle plate. Each grinding area of 1 square meter, repeatedly sliding the stone notches grinding to smooth the grinding water is moderate to prohibit dry grinding, suction machine sucking, net absorption of the ground.
3 shut up with the change the small mouth of the metal disc sequentially grinding genuine notches, to eliminate the rough grinding marks. Repeated grinding, scraping, sucking up the ground.
In order to use 50 #, 200 #, 400 #, 800 # granite refurbished discs, continue grinding.
5 1500 # 3000 # polished wafer surface polishing the stone surface wash and dry.
