产品特性:
板状刚玉具有良好的加热体积温度和良好的隔热性能。 晶体以扁平的形状存在,增加了颗粒的机械强度。 晶体和晶体的内部主要分布在均匀闭合的孔中。 重新产生液体消耗;高燃料耐药性,良好的热冲击稳定性,低热收缩速度和良好的热负荷强度。 同时,较高的纯度避免了杂质进入系统。 这是制造防火,陶瓷材料和绝缘材料的理想原材料。
Production feature:
Tabular alumina has good heat resistance and good bulk temperature thermal shock capabilities. The crystal staggered plate shape, to increasing the mechanical strength of the particles; interior structure full of closed pores, high bulk density, low apparent porosity and water absorption, to reducing the amount of fluid re-use productions; With good physical properties like: high refractoriness, excellent thermal shock resistance, low shrinkage and good thermal load strength etc. Meanwhile, high-purity avoiding damage to machines. Hiaxu/Sicheng is your best choose as refractory material/ceramic material and insulating materials.
