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.
