Clay insulation bricks are mainly used as the insulation layer in various kilns that do not directly come into contact with flames, with the working environment temperature ranging from 800℃ to 1200℃. Clay insulation bricks generally do not come into direct contact with flames and are used in the insulation layer of kilns. The main function of clay insulation bricks is to achieve effective insulation and reduce the heat transfer between the kiln and the outside air.

Advantages of clay insulation bricks

Low thermal conductivity

The thermal conductivity of clay insulation bricks is relatively low, typically ranging from 0.23 to 0.65 W/(m-K). This means that in the same thickness, clay insulation bricks can offer better insulation performance and reduce heat transfer. 

Low heat capacity

The heat capacity of clay insulation bricks is generally 0.8 - 1.2 kilojoules/(kilogram K). This advantage means that when the clay insulation bricks are washed, the energy required to absorb or release heat is very little, thus enabling them to quickly adapt to temperature changes. 

Environmental protection

Clay insulation bricks are made from natural clay and do not contain harmful substances. They do not produce harmful gases or pose any threat to human health, and are beneficial to the environment. 

Stable performance

Clay insulation bricks have excellent durability and stability. Due to the inherent stability of the material, their performance will not deteriorate even after long-term use under high temperatures.

Application of Clay Insulation Bricks

Metallurgical Industry

Clay insulation bricks can be used as the insulation layer in high-temperature kilns, melting furnaces, heating furnaces, etc. Clay insulation bricks have a low thermal conductivity and can withstand high temperatures, making them an ideal choice. 

Petroleum industry

Clay insulation bricks can be used as insulation layers for reactors, distillation towers and other equipment. Clay heat insulation bricks can effectively reduce heat conduction and have excellent heat insulation properties. 

Electric power industry

Clay lightweight bricks are mainly used in boilers and chimneys of power plants. Clay insulation bricks are key equipment in the power generation process that generates high temperatures, and they can improve the energy efficiency of boilers. 

Glass industry

Clay insulation bricks are usually used as the inner lining and insulation layer of glass kilns. Clay insulation bricks can withstand high temperatures and have good insulation properties, which helps to improve the energy efficiency and production efficiency of glass kilns.
