Industrial furnace used refractory diatomite brick

You may submit your questions by filling the form.

Diatomite brick is an insulating product made of porous diatomaceous earth. The main raw material for the natural production of porous diatomaceous earth, and then add a small amount of clay and combustible materials. The bulk density of diatomite brick is 0.7g / cm3, the compressive strength is 1 ~ 2MPa at room temperature, 0.13 ~ 0.20W / (mK) at 400 ℃, the apparent porosity is more than 70%, the coefficient of thermal expansion ( 1280 ℃) is 0.9 × 10-6 ℃ -1, the refractoriness is greater than 1250 ℃. Mainly used for industrial furnaces and other thermal equipment, heat pipe insulation materials, generally bear the hot surface temperature is about 1000 ℃ or so.
