What's the difference between refractory bricks and insulating bricks?
Insulation brick mainly is used to heat, reduce heat loss, refractory brick is mainly used to withstand flame burn. Bricks usually do not contact fire directly, while refractory bricks usually contact the flame directly.
In the preferred insulation performance, the thermal conductivity of insulating brick insulation brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better. In the degree of refractoriness, the refractoriness of insulating bricks is generally below 1400 degrees, while the refractoriness of refractory bricks is above 1400 degrees. In density, insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
As far as we are concerned about the characteristics of refractory bricks and thermal insulation bricks, refractory bricks are sure to be aimed at fire resistance, while insulating bricks are more focused on thermal insulation. And more specifically, let's take a look at the following parameters.
