Tabular alumina板状刚玉0.5-1mm
【发表人:王青】【来源:Tabular alumina板状刚玉0.5-1mm】【发布时间:2019/4/19】

板状刚玉具有良好的加热体积温度性和良好的抗热震能力。其晶体呈平板状交错排列,增加了颗粒的机械强度;晶内和晶间以分布均匀的闭气孔为主,体积密度高,显气孔和吸水率低,减少了再制品的用液量;具有高耐火度、良好的热震稳定性、低热收缩率和良好的热负荷强度等优越的物理性能。同时,高纯度避免了杂质对系统的污染,是制作高级耐火材料、陶瓷材料和绝缘材料的理想原料。

 

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.

     

板状刚玉是一种理想的耐火材料,既可以作为骨料应用于各种铝质耐火材料中,也可以添加到其他铝质不定型耐火材料中。

Tabular alumina is an ideal refractory material, either can be used in various refractory alumina, or can be add in other unshaped refractories
