Alumina powder using industrial alumina, aluminum hydroxide plus additive technology, low temperature phase inversion after calcining, again USES the advanced grinding technology and process, the activity of producing alumina powder, its characteristic is active, fine granularity.Particularly applicable to finalize the design product and refractory castable, plastic, repair materials, gunning materials, daub materials such as monolithic refractories, to improve the refractory material of high temperature strength, improve the erosion resistance of has a strong role. Alumina powder is made of white corundum industrial raw material, the arc after cooling in integrated by more than 2000 degrees high temperature melting, after smashing plastic, magnetic separation to iron, screen is divided into a variety of particle size, dense texture, high hardness, granular form sharp corners, consolidation is suitable for making ceramic, resin abrasive and grinding, polishing, sandblasting, precision casting, etc., can also be used for manufacturing advanced refractories.Product size according to the international standard and national standard production, granularity processing according to user requirement.Gm grain sizes of the F4 ~ F220, its chemical composition depending on the size of the particle size.Outstanding characteristic is little impact resistance, crystal size in the mill processing, particles are spherical particles, the surface dry clean, easy to bond.
Alumina powder white loose powder, high whiteness, low bulk density, stable at room temperature, thermal decomposition generate alumina dehydration.This product is different from other flame retardant material, it does not produce toxic and corrosive gas pyrolysis, and pyrolytic heat absorption and release water vapor, can make the products flame retardant self-extinguishing, thus in advanced composite materials such as plastic, rubber, this product is added to the not only make products with flame retardant smoke abatement effect, and leakage resistance, arc resistance, abrasion resistance performance enhancements. 1, aluminum oxide polishing powder through high temperature calcined alpha Al2O3 powders, also contain dispersant, suspending agent, lubricant, emulsifier and other auxiliary ingredients, widely used in the thermal conductivity, polishing, electroplating, catalyst, etc. 2, alumina powder is particularly suited to finalize the design product and refractory castable, plastic, repair, gunning materials, daub material, binder, monolithic refractories, such as high purity refractory fiber to improve the refractory material of high temperature strength, improve the erosion resistance of has a strong role. 3, alumina powder is true than major, high hardness, good abrasion resistance, impact resistance and other characteristics, preparation for machine, optical processing, tableware industry, jewelry processing, auto parts repair maintenance, optical lenses, machines, electrical accessories, and so on need polishing surface treatment industry. 4, alumina powder for making teeth glinting cement, ceramics, special ceramics, electronic ceramics, packing, mordant, metal aluminum paint, etc.Can be added to the various water-based resin, oil resin, epoxy resin, acrylic resin, polyurethane resin, plastic, rubber, the adding amount of 3% to 3%, can obviously increase the material hardness, hardness can be up to 6 to 8 h is even higher.
