Difference between refractory brick and insulation brick

Effect of heat insulation brick is used to heat preservation, reduce heat loss, refractory brick is mainly used to withstand flame burn. Insulating brick is generally not direct contact with the flame, and refractory brick general direct contact with the flame.

The main difference between the following points:

• Insulation performance

Thermal conductivity of thermal insulation brick in general 0.2-0.4 (average temperature 350 ± 25 ℃) w/m.k, and refractory brick of heat conduction coefficient in 1 (the average temperature 350 ± 25 ℃) than w/m.k, which can obtain insulating brick insulation performance than the refractory brick insulation performance is much better.

• Refractoriness

Insulating brick refractoriness generally below 1400 degrees, and refractory refractory degree is above 1400 degrees.

• Density

Insulating brick is generally a lightweight thermal insulation material, density in 0.8-1.0g/cm3 and refractory brick of basic density is above 2.0g/cm3.

To make a long story short insulating brick is generally emphasized the insulation performance of it, does not pay attention to its refractoriness fire brick, and on the contrary. Different locations will use different materials, in the purchase of materials at the same time, to choose their own use.
