Introduction of alumina powder

Alumina powder is to produce the basic materials of heat-resisting, wear-resisting, corrosion products, such as high alumina refractories, high-strength ceramics, automobile spark plugs, advanced grinding material, etc. Alumina with powder, particle size uniform, easy to spread, and has high purity, high melting point, good thermal stability, smaller than major, reduction, high hardness, good electrical insulation, acid and alkali corrosion resistance and other characteristics, widely used in setting, monolithic refractories and refractory castable binder, high purity refractory fiber, special ceramics, electronic ceramics, etc.

Shizuishan Jin Lin corundum refractories co., LTD., the production of alumina powder is 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 characteristics

1, crystal particles on the phase stability, high hardness, small and uniform distribution;

2, strong grinding force, fast polishing, photometric lights, mirror effect is good;

3, high grinding efficiency, good polishing effect, high surface finish, strong cutting force, fast out of the light, can throw evenly and bright ze.

 

Alumina powder use

Aluminum oxide polishing powder through high temperature calcined alpha Al2O3 powder, have other dispersing agent, suspending agent, lubricant, emulsifier and other auxiliary ingredients, widely used in the thermal conductivity, polishing, electroplating, catalyst, etc.

1, 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.

2, 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.

3, 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.
