Introduction of diatom brick

Diatom brick is a kind of heat insulation product made of porous diatomite. The main raw material is natural porous diatomffite, adding a small amount of bonded clay and combustible matter. The volume density of diatomite refractory brick for 0.7g/cm3 at room temperature, the compressive strength is 1 ~ 2MPa, The thermal conductivity is 0.13 ~ 0.20W/ (M. K) at 400 c, The coefficient of thermal expansion (1280 degrees) 0.9 * 10-6 -1 C. Diatom brick is mainly used in industrial kilns and other thermal equipment, heat pipe insulation materials, generally withstand the hot surface temperature is about 1000 degrees celsius.
