Product Description
Alumina powder
Alumina powder is the use of first grade industrial alumina, aluminum hydroxide plus additive
technology, low temperature phase calcination, and then the use of advanced grinding technology and technology, the production of white activated alumina powder,which is characterized by uniform particle size, easy to disperse, stable chemical properties, moderate shrinkage performance at high temperature, with good sintering performance, high conversion rate, low sodium content. It is especially suitable for shaped products and amorphous refractory materials such as refractory castable, plastic, repair material, spray filler, and coating material, which has a strong effect on improving the high temperature strength of refractory materials and improving the corrosion resistance of materials.
Alumina powder Fetures：
high filling： The particle sphericity is high, the particle size distribution is wide, and the rubber and plastic can be filled with high density, and the mixture with low viscosity and good fluidity can be obtained. If added to a variety of acrylic resin,polyurethane resin, epoxy resin, melamine resin, silicone acrylic emulsion and other resins in the water-based liquid, theaddition amount of 5% to 10%, can improve the hardness of the resin, hardness up to 6-8H.
high thermal conductivity：It can be filled with high density, and can obtain a mixture with high thermal conductivity and good heat dissipation compared with crystalline silicon powder.
low wear：Its appearance is spherical, the wear of mixing machine, forming machine and mold equipment is greatly reduced, and the service life of the equipment can be extended.
