Definition and application analysis of aluminium oxide industry
aluminium oxide abrasive cloth,aluminia flap disc,aluminium oxide flap wheel
Aluminium oxide, the common name is also called corundum, corundum with high quality bauxite as raw material, anthracite coal, iron, longitude above high temperature smelting in electric arc furnace, the mill grinding plastic, magnetic separation to iron, screen is divided into a variety of particle size, dense texture, high hardness, particle formed globular, consolidation is very suitable for making ceramic, resin abrasive and grinding, polishing, sandblasting, precision casting, etc., can also be used for manufacturing advanced refractories.
The main component of brown corundum is alumina, and the grade is determined by the aluminum content. The lower the aluminum content, the lower the hardness. Aluminium oxide is widely favored by the international jet industry for its superior performance and economical price. At present, it is widely used in sandblasting, derusting, optics, electronics, building materials, mechanical processing, instruments, instruments, printing, grinding, stone, rubber, hydraulic jet and cutting industries.
