How to Distinguish Between Insulation Brick and Firebrick?

June 18, 2018
There are obvious differences between insulation brick and fire brick. In short, the following five points:
1、Insulation.
The thermal conductivity of thermal insulation brick is usually 0.2-0.4 (average temperature 350±25 ℃) w / m·k, while the firebrick thermal conductivity of 1.0 (average temperature 350±25 ℃) w / m·k above.
2、Refractoriness
The fire resistance of insulation brick is usually below 1400 degrees, and The fire resistance of firebrick is above 1400 degrees.
3、Density
Insulation brick is usually lightweight insulation materials, the density is usually 0.8-1.0 g/cm3 and the density of firebrick is all above 2.0 g/cm3.
4、Use
Insulation brick is mainly used for thermal insulation and reducing the loss of heat, and firebrick mainly burning the flame.
5、Flame
Insulation brick generally does not come into direct contact with the flame, while the brick usually comes into direct contact with the flame.
In summary, Insulation brick is a kind of new building energy-saving thermal insulation material mainly made of inorganic composite materials,and firebrick has high mechanical strength, long service life and good chemical stability. When build the wall, the excellent Insulation effect into the wall. The use of the environment, scope and role is not the same, and different locations will use different material. It is recommended to customers according to their own actual situation, to determine the appropriate refractory.
