Introduction of Industry Furnace Lining Clay Insulation Brick
Insulation bricks are made of bauxite, mullite, kaolin and other raw materials, which are screened and evenly mixed with binders, and then fired at high temperature after pressing.
There are many types of lightweight insulation bricks, including fire clay insulation bricks, mullite insulation bricks, alumina hollow ball bricks, silicon insulation bricks, etc.
The insulation brick has the properties of high porosity, low thermal conductivity, light weight, thermal insulation, and Good thermal shock resistance. Mainly used in industrial equipment lining, insulation layer, kiln door backing, roof and other parts.
Features of Rongsheng Clay Insulation Fire Brick:
High Refractoriness. Can't contact with the flame directly.
High Porosity
Low Thermal Conductivity
Low Bulk Density
Good Thermal Shock Stability
Excellent Heat Insulating Effect And Energy -efficient
Corrosion And Erosion Resistance
Long Service Life
