Silicon carbide, dense planting sand, E-type paper or F-type paper, the sand surface is coated with zinc stearate super coating, which has anti-static and anti-blocking effects, and is suitable for wide abrasive belts. Mainly used in: furniture, woodware, handicrafts, musical instruments, floors, resin products and other paint surface treatment. Grit: 100#-600#Brown fused alumina, F-type paper, sparse planting sand, anti-static function, stable tensile coefficient, good abrasion resistance, suitable for various wide or narrow abrasive belts. Mainly used in: furniture, woodware, handicrafts, musical instruments, flooring, leather, resin products and other paint surface treatment. Grit: 60#-400#Silicon carbide is an inorganic substance with a chemical formula of SiC. It is made by high temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (salt is needed to produce green silicon carbide) through a resistance furnace. There are two basic varieties of silicon carbide, black silicon carbide and green silicon carbide, both of which belong to α-SiC. Brown fused alumina is an artificial corundum produced by melting and reducing three raw materials: bauxite, carbon material and iron filings in an electric arc furnace. The main chemical component is AL2O3, the content of which is 95.00%-97.00%, and a small amount of Fe, Si, Ti, etc. Silicon carbide, C-type paper or D-type paper, densely planted sand, the sand surface is coated with zinc stearate super coating, which has anti-static and anti-blocking effects. It is suitable for wide or narrow abrasive belts below 700mm. Mainly used in: furniture, woodware, handicrafts, musical instruments, resin products and other paint surface treatment. Grit: 150#-1000#
