The difference between refractory bricks and insulation bricks

refractory bricks and insulation bricks are two different materials. What are the specific differences between insulation bricks and refractory bricks? The following will introduce the difference between refractory bricks and insulation bricks.

1. The difference between refractory bricks and insulation bricks raw materials

Refractory bricks are usually made of high temperature resistant materials, such as clay, high alumina, silicate, etc. These materials have the characteristics of high temperature resistance and chemical corrosion resistance, and are suitable for buildings and equipment in high temperature environments.

Insulation bricks are usually made of materials such as lightweight aggregate, cement and foaming agent, so they have lower density and better thermal insulation performance.

In the production process, the raw materials of thermal insulation bricks need to be mixed, stirred with water, foamed in the mold, and finally formed by curing; while refractory bricks usually need to go through multiple processes such as molding, drying, and sintering.

2. The difference between refractory bricks and insulation bricks

Refractory bricks are mainly used to build equipment and structures that can withstand high temperature and chemical corrosion, such as furnaces, kilns, etc.; while thermal insulation bricks are mainly used for thermal insulation, and are used in cold storage, firewalls, exterior walls of houses, etc.

3. The difference between the thermal conductivity of refractory bricks and insulation bricks

Insulation bricks have good thermal insulation performance, and the thermal conductivity is small, usually 0.2-0.5W/(m·K); while the thermal conductivity of refractory bricks is relatively large, usually 1.0-1.5W/(m·K).

4. The difference between refractory bricks and insulation bricks

Refractory bricks are usually made of high temperature resistant materials such as clay, high alumina or silicate, while thermal insulation bricks are mainly composed of lightweight aggregates, cement and other materials.

5. The difference between the density of refractory bricks and insulation bricks

Due to the different materials, refractory bricks are usually heavier and denser than insulating bricks.

To sum up, there are obvious differences between refractory bricks and insulation bricks in terms of material, main function, density and thermal conductivity.
