Hollow ball brick and corundum not come to alumina the distinction of stone brick

Hollow ball brick and corundum not come to alumina stone brick is high temperature fireproof material, with Yu Naigao lukewarm, anticorrosive industrial equipment liner and heat insolation. They pledge in sex of material composition, physics and apply a respect to exist a few important distinction:
Material composition: Alumina is hollow ball brick: Main by alumina (Al2O3) for bases, still contain other additive normally, in order to raise its high temperature resistant with corrosion resistance can. Corundum not comes stone brick: Corundum (Al2O3) with Molaishi (Mullite, namely 3Al2O3 · 2SiO2) it is its bases. These two kinds of material are synthesized in brick, make its have good high temperature stability and corrosion resistance.
Content reason is simple: Alumina is hollow ball brick: Have inferior density normally, high temperature coefficient of thermal conductivity is inferior, because this is in the application of heat insolation of a few requirements very useful. Their intensity may be relatively inferior. Corundum not comes stone brick: Have higher density and property of high temperature heat conduction, because this is in,bigger thermal shock bears in environment of a few high temperature. They have higher strength normally.
Use a field: Alumina is hollow ball brick: Commonly used apply at a few light qualitative adiabatic heat insolation, it is for example in the liner of industrial heat heat or thermal insulation. Corundum not comes stone brick: Commonly used at needing to bear higher temperature is mixed the application of more serious corrosion environment, wait like kiln of vitreous kiln, steely smelting furnace, cement.
Corrosion resistance: Alumina is hollow ball brick: Opposite Yu Gangyu not comes stone brick, its corrosion resistance can be poorer, fit clean high temperature environment more normally. Corundum not comes stone brick: Have better corrosion resistance, can use in a few acidity or alkalescent environment.


The place on put together is narrated, hollow ball brick returns choice alumina is corundum Mo Laishi brick depends on your specific application demand. If need more adiabatic function and inferior density, alumina is hollow ball brick may be better choice. But in higher temperature, more serious corrosion environment, the brick may suit corundum Mo Laishi more. Before the choice, the proposal seeks advice from flourish Cheng Naicai or be able to bear or endure professionally material engineer, designing institute, accord with the requirement of specific project in order to ensure.
