Insulation bricks are mainly used to retain heat and reduce heat loss. For example, mullite bricks; while refractory bricks are mainly used to withstand the flame. Insulation bricks are generally not directly in contact with the flame, while refractory bricks are generally directly in contact with the flame. Such as high aluminum bricks; the main difference between the following points:
1, thermal insulation performance
Thermal conductivity of insulation bricks is generally 0.2-0.4 (average temperature 350 ± 25 ℃) w/m.k, while the thermal conductivity of refractory bricks in 1.0 (average temperature 350 ± 25 ℃) w/m.k above, which can be concluded that the thermal insulation of insulation bricks than the refractory bricks insulation performance is much better.
2, refractoriness
The refractoriness of thermal insulation bricks is generally below 1400 tons, while the refractoriness of refractory bricks is above 1400 degrees.
3、Density
Insulation bricks are generally lightweight insulation materials, density is generally 0.8-1.0g/cm3 and refractory bricks are basically in the density of 2.0g/cm3 or more.
