氧化鋁粉特點
1、高填充性；其粒子球形率高、粒度分布寬，可對硅橡膠、塑料進(jìn)行高密度填充，可得到粘度低、流動性較好的混合物。
2、高熱傳導(dǎo)率；因其可高密度填充，與結(jié)晶硅微粉相比，可得到熱傳導(dǎo)率高、散熱性好的混合物。
3、低磨損性；因其外觀為球形，對混煉機、成型機及模具等設(shè)備的磨損大大降低，可延長設(shè)備的使用壽命。
1, high filling; Its high rate of spherical particles, the particle size distribution b, can undertake high density filling of silicone rubber, plastic, low viscosity, liquidity available good mixture.
2, high thermal conductivity; Because of its high density populated, compared with crystalline silicon powder, high thermal conductivity, heat dissipation good mixture can be obtained.
3, low wear and tear "; Because of its appearance is spherical, the mixing machine, molding machine and mold equipment wear and tear is greatly reduced, can prolong the service life of equipment.
