Product Description:
Brown fused alumina is made from bauxite coke by high temperature smelting in electric arc furnace. After raw material sorting, electrolytic smelting, crushing, ferromagnetic separation, screening, physical and chemical inspection, finished product packaging, warehousing and other production processes. It has the characteristics of high hardness, good crystallization, good linear fluidity, less adhesion in use, non-explosion, non-cracking and non-pulverization in use. The abrasives made by him show dark blue after calcination, no network cracks and no rust spots
Application:
1. Used for refractory materials, castable refractory bricks, etc.
2.sand blasting - BFA as abrasive,hardness is moderate, high bulk density, no free silica, large specific gravity, good toughness, is an ideal "environmental" type sand blasting material, widely used in aluminum profiles, copper profile glass, washed denim Precision molds and other fields
3. grinding grade abrasive-applied to picture tube, optical glass, monocrystalline silicon. Lens. watch glass.crystal glass.jade. etc.,
4, resin grinding -with suitable color.hardness. Toughness. particle cross-section type and edge retention.it is applied to resin abrasives with ideal effect;
5, coated abrasives - sandpaper.gauze
6, functional fillers- mainly used in automotive brakes. special tires. special construction products.etc.
