Mullite Poly Light Insulation Brick JM30 used in Tunnel Kiln

Mullite poly-lightweight insulation brick JM30 is an insulation material made of mullite as the main raw material and made through high-temperature sintering. This material has the characteristics of lightweight, low thermal conductivity, and high-temperature resistance. It is often used as the insulation layer of high-temperature industrial furnaces such as tunnel kilns.

In tunnel kilns, JM30 insulation bricks may be used in the following locations:

Insulation layer for furnace top and furnace wall: In the furnace roof and furnace wall parts of the tunnel kiln, JM30 insulation bricks can be used as insulation materials to help reduce heat loss and improve energy utilization efficiency.

Insulation layer inside the kiln tunnel: To reduce heat loss inside the tunnel kiln, JM30 insulation bricks can also be used as the insulation layer in the kiln tunnel to help maintain high-temperature combustion conditions.

Insulation of other high-temperature areas: There may be other high-temperature areas in the tunnel kiln, such as drying areas, preheating areas, etc., and JM30 insulation bricks may also be used as insulation materials in these areas.

It should be noted that JM30 insulation brick is a lightweight insulation material. Its main feature is excellent insulation performance, but it is relatively weak in fire resistance. Therefore, in specific applications, it is necessary to evaluate whether the tunnel kiln is suitable for use according to the process conditions, design requirements, and standards, and to ensure that it can work stably in high-temperature environments.

In the design of the insulation layer of a tunnel kiln, insulation materials of different types, densities, and thicknesses are often selected according to the operating temperatures and requirements of different areas to achieve the ideal insulation effect.
