Sponge sand is also called sponge polishing sand, CNC post grain polishing sand, CNC polishing sand, foam polishing sand, etc. The surface is sand and the inside is sponge, so it has super flexibility.
Features: Sponge sand combines the excellent characteristics of water resistance, acid and alkali resistance, and has the characteristics of wet and dry use. It can achieve the ideal effect regardless of the hand grinder. It is suitable for the grinding of any irregular geometric curved surface. Its density and flexibility, high toughness, good self-sharpness, low sand consumption and can be recycled, good abrasive finish; and stable chemical composition, wear resistance, acid and alkali resistance. The abrasive shell-shaped fracture has sharp edges and corners, which can form new edges and edges during continuous crushing and classification, making its grinding ability better than other abrasives. In particular, it has the advantages of high hardness, large specific gravity, stable chemical properties and its unique self-sharpness. Sponge polishing sand has become the first choice for effectively solving the abrasives used in the grain polishing process after CNC processing. Ideal material for grinding and polishing. Under the premise of maintaining the functions of traditional water sandpaper, all the shortcomings of water sandpaper are overcome, the lotus strength of the abrasive object is greatly reduced, the grinding efficiency is doubled, and the same consumption cost is longer than the water sandpaper bottom, and the service life is longer. . Because of its own water storage function, it can reduce the amount of flushing and drainage work, and it is comfortable to hold, and it is very convenient to use. It can also be used dry and grind various types of metal and wood products. It is used for household manufacturing, automobile repair, and metal rust removal. It can do more with less in the injection molding industry. It can handle slip marks and burrs on the surface of injection molded products, and can also be polished.
Main application: Sponge sand is mainly used to effectively solve the effects of CNC machining, stainless steel surface decontamination, welding slag and matt effect, iron workpiece derusting, decontamination, descaling, increase coating and coating adhesion, Aluminium workpiece descaling, surface strengthening, light decoration, copper workpiece descaling matte effect, glass products crystal frosted, engraved patterns, plastic products (hardwood products) matte effect, CNC processing after grain, smart phone, Processing of special metals and materials such as computers and increasing the effect brightness.
Scope of application: Sponge sand is very suitable for CNC processing, metal surface rust removal and plastic surface treatment. It is very well used in the polishing surface of digital electronics, smart phones, LCD computers and other products and automotive repair paint.
Common abrasives for sponge sand are: brown corundum, white corundum, silicon carbide, zirconium corundum, alumina, ceramic corundum.
