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.

Polishing pads can be divided into abrasive polishing pads and non-abrasive polishing pads, depending on whether they contain abrasives; Depending on the material, they can be divided into polyurethane polishing pads, nonwoven polishing pads and composite polishing pads. according to different surface structures, they can be roughly divided into flat, grid and spiral.

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.

To take advantage of the grinding and polishing properties of the high speed polishing machine, for a new floor with good flatness, first use a grinding machine with a grinding wheel with a grain size of 300-500 for fine grinding, apply a sealing hardener, and use 1 after that the hardener is completely absorbed. Diamond polishing pads equipped with high speed polishing machine can polish the concrete floor without exposing the aggregate, and the surface is polished with a sealing hardener.
