The polishing pad can effectively and evenly transport the polishing fluid to different areas of the polishing pad, and at the same time, the chemical reaction after polishing can be carried out completely.

The polishing pad is made by mixing nano-scale silica particles with a high-efficiency binder, and then uniformly coating the surface of the polyester film, and then drying and curing reaction.

The polishing pad is a kind of elastic, loose and porous material, which is a common polyurethane material. The polishing pad and the polishing liquid work in synergy and cooperate with each other to complete the polishing work.

The diamond polishing pad is suitable for portable electric or pneumatic grinding machines, and then the joint is connected, the power is 750-1500 W and the speed 2000-10000 revolutions. When working, apply a certain pressure on the machine while running the water 4-5 times on the surface of the stone to be sanded, and then the finer grinding plate No. 1 can be replaced.
