Uses of brown corundum

Brown corundum is also known as emery, the main chemical composition of brown corundum is AL2O3, its content is 95.00%-97.00%, the particle shape is uniform, into angular crystal, with sharp edges, high grinding force, so what are the uses and characteristics of brown corundum? Uses of brown corundum:

1, free grinding - abrasion-grade abrasives, used for picture tube, optical glass, free grinding monocrystalline silicon, lens, watch glass, crystal glass, jade and other fields, is commonly used in China high-grade abrasives.

2, with the appropriate color, hardness, toughness, suitable particle cross section of the abrasive type and edge retention, applied to resin abrasive.

3, coated abrasives - abrasive materials are the raw materials of sandpaper manufacturers, gauze, etc.

4, functional fillers - mainly used for automotive brakes, special tires, special construction products and other collars can be used as building highway pavement. Dock parking industrial floor sports field and other wear resistant materials.

5, sandblasting - medium hardness abrasive, high packing density, no free silicon oxide, significant, good toughness, is the ideal "environmental protection" sandblasting material, widely used in aluminum, copper profile glass, washed denim precision mold and so on;
