棕刚玉微粉Brown Fused Alumina Microgrits
 
棕刚玉微粉以优质铝矾土为主要原料，在电弧炉中经过2200℃以上高温中冶炼提纯、还原、结晶、分选、破碎、磁选、筛分等加工手段精制而成，微粉经过水洗、风分，具有粒度标准、砂质干净，磨削力强、韧性好，强度大，抗冲击、耐高温、抗氧化、耐腐蚀等特性，主要用于制作砂纸、纱布、磨块、小磨头、抛光蜡、油石、百洁布、磨轮等产品。
Brown fused alumina microgrits is melted and refined in the electric arc furnace through more than 2,200 ℃ high temperature with high-quality bauxite as the main raw material comes with purification, reduction, crystallization, sorting, crushing, magnetic separation, screening and other processing means. Microgrits, which has been washed and air blasted, owns the characteristics of particle size standards, sand clean, strong grinding force, good toughness, strength, impact resistance, high temperature, antioxidant, corrosion resistance and others. It is mainly used in the production of sandpaper, gauze, grinding block, small bistrique, polishing wax, whetstone, cleaning cloth, grinding wheel and other products.
