The difference between insulation brick and 내화 벽돌

1. Insulation performance

The thermal conductivity coefficient of thermal insulation brick is generally 0.2-0.4 (average temperature 350±25℃) w/mk, but the thermal conductivity coefficient of refractory brick is above 1.0 (average temperature 350±25℃) w/mk, and the thermal insulation performance of thermal insulation brick is better than that of refractory The thermal insulation properties of bricks are much better.

2. 내화성

The fire resistance of thermal insulation bricks is generally below 1400 degrees, while the fire resistance of refractory bricks is above 1400 degrees.

3. Density.

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.
