Diatomite Brick

We are engaged in manufacturing and exporting excellent quality Diatomite Brick to our valuable clients. Made with porous diatomite insulation products. The main raw material for the production of porous natural diatomaceous earth, then add a small amount of a combination of clay and combustible materials. The bulk density of diatomaceous earth brick 0.7g / cm3, the compressive strength at room temperature for 1 ~ 2MPa, the thermal conductivity is 400 a , 0.13 ~ 0.20W / (m A. K), the apparent porosity of greater than 70%, the thermal expansion coefficient (1280 a when) is 0.9 A 10-6 a -1, refractoriness greater than 1250 a . Mainly used in industrial furnaces and other thermal equipment, thermal pipe insulation materials, generally withstand hot surface temperature of about 1000 a .
