Brief introduction of lightweight fire clay insulation bricks
Lightweight fire clay brick is a kind of thermal insulation material, which refers to the thermal insulation brick with high porosity, low volume density and low thermal conductivity. Lightweight insulation bricks are characterized by their porous structure (porosity is generally 40 ~ 85%) and high heat insulation.
Features of lightweight fire clay insulation brick
Low heat capacity.
Low shrinkage rate.
High insulation.
High fire resistance.
Low volume density.
Low thermal conductivity.
High strength, corrosion resistance.
