Comparison of lightweight insulating fire bricks and heavy bricks

1. Thermal insulation performance: The thermal conductivity of lightweight bricks is generally 0.2-0.4, while the thermal conductivity of heavy bricks is above 1.0. It can be concluded that the thermal insulation performance of lightweight bricks is much better than that of heavy bricks.

2. Refractoriness: The refractoriness of lightweight bricks is generally below 1400 degrees, while the refractoriness of heavy bricks is above 1400 degrees.

3. Density: Lightweight bricks are generally lightweight insulation materials, the density is generally 0.8-1.0g/cm3 and the density of heavy bricks is basically above 2.0g/cm3.

Heavy bricks are very different from light bricks, and their use environment, scope and function are different. Different materials will be used in different locations. When purchasing materials, we must decide which refractory material is suitable for our own use according to our actual situation.
