Diatomite Firebrick

An insulating product made of porous diatomite.The main raw material is naturally produced porous diatomite, and then add a small amount of binding clay and combustible.The volume density of diatomite brick is 0.7g/cm3, the compressive strength at room temperature is 1 ~ 2MPa, the thermal conductivity at 400ºC is 0.13 ~ 0.20w /(m·K), the apparent porosity is greater than 70%, the thermal expansion coefficient (1280ºC) is 0.9×10-6ºC-1, and the fire resistance is greater than 1250ºC.Mainly used for industrial kilns and other thermal equipment, thermal insulation materials, the general temperature of the heating surface is about 1000ºC.Mainly used for industrial kilns and other thermal equipment, thermal insulation materials, the general temperature of the heating surface is about 1000ºC.
