The main function of insulation bricks is to keep warm and reduce heat loss. Thermal insulation bricks generally do not directly touch the flame, while refractory bricks generally directly touch the flame. Refractory bricks are mainly used to withstand the burning of flames.
The main differences between insulation bricks and refractory bricks are as follows:
1. Insulation performance
The thermal conductivity of insulation bricks is generally 0.2-0.4 (average temperature 350±25℃) w/mk, while the thermal conductivity of refractory bricks is above 1.0 (average temperature 350±25℃) w/mk. The thermal insulation performance of insulation brick is much better than that of refractory bricks.
The refractoriness of insulation bricks is generally below 1400 degrees, and the refractoriness of refractory bricks is above 1400 degrees.
Insulation bricks are generally light-weight insulation materials with a density of 0.8-1.0g/cm3 and the density of refractory bricks is basically above 2.0g/cm3.
