Using special high elastic sponge as the substrate, it has high hardness, fast rebound and high density sponge. The sponge block is coated with lv alumina emery on all sides, so that the sponge grinding block not only has a super grinding effect, but also has elasticity and does not hurt hands. , easy to hold and can be used both wet and dry;
In addition to maintaining the grinding and polishing function of traditional water-resistant sandpaper, the sponge sand block also overcomes all the shortcomings of water-based sandpaper, which greatly reduces the labor intensity when grinding products, improves the grinding efficiency several times, and consumes the same cost. low and long service life.
The special water storage effect of the sponge can reduce the workload of flushing and chip removal, and it is comfortable to hold and very convenient to use; it can also be used dry to grind various metal surfaces, curved surfaces of wood products, grooves and other difficult-to-reach parts .
It is widely used in furniture manufacturing, auto repair, musical instrument paint, and metal rust removal. It is more ideal for grinding and polishing in the injection molding industry. It can deal with slip marks and burrs on the surface of injection molded products, and can also be polished. At the same time, it is handy to grind any arc for different products, so there is no need to worry that some curved surfaces cannot be polished.
