Ceramic granulation grain 99 % alumina purity surface polishing porcelain material
Product name : Alumina granulation powder
Specification : HY-ZLF-99
Introduction of alumina granulation powder :
Alumina granulation powder usually adopts spray granulation process, that is, the slurry with dispersant and binder is dispersed into droplets by atomizer, and the microsphere solid particles are obtained by direct contact between hot air and droplets. These spherical particles can greatly improve the fluidity of the powder and increase the filling density of the mold, thereby improving the sintering performance of the device, which is of great significance for alumina granulation powder. Granulation is the practice of assembling a pile of small powders into large particles. At present, this technology has been widely used in medicine, food, building materials, chemical industry, metallurgy and other industries.
Characteristics of alumina granulation powder :
Widely used, small shrinkage, suitable for large suitable for large blanks, porcelain delicate, high density, pressed body does not crack.
The powder does not stick to the mold, the ceramic parts have no pores, and the powder has good consistency.
Application of alumina granulation powder :
Alumina ceramics, textile ceramics, electronic ceramics, structural ceramics, high-grade seals ; electronic substrate, bracket, plunger, cylinder liner, wear-resistant plate, seal, refractory, acid and alkali resistance, high insulation, bulletproof sheet.
The purpose of alumina granulation powder :
1 Change the shape : improve the fluidity of the powder, or reduce the adhesion, or easy to take, or improve the dispersion.
2 Reduce specific surface area : reduce moisture or solubility, or increase preservation.
3 Increase the bulk density : reduce dust, or convenient transportation, or reduce transportation costs.
4 Change the particle size distribution : narrow the particle size distribution, or broaden the particle size distribution, or reduce the small particle size of the powder.
5 convenient pressure synthesis type.
