Mullite Insulating Refractory Brick JM23 JM26 JM28
The Description:
Mullite thermal insulation refractory brick refers to mullite as the main raw material, through grinding, mixing, forming, drying, sintering and other processes made with excellent thermal insulation, refractory properties of the brick. Mullite is a natural mineral with a magnesia-aluminosilicate structure, and its main chemical components are SiO2, Al2O3 and MgO.

Product feature:
1. Excellent thermal insulation performance: Mullite insulated firebrick has a very low thermal conductivity, which can effectively reduce the transfer of heat energy, so as to achieve excellent thermal insulation effect.
2. Stability at high temperatures: Mullite insulated firebricks show high erosion resistance and chemical stability at high temperatures, and are not easy to deformation and fall off.
3. Good mechanical strength: Mullite insulated firebrick has good mechanical strength and pressure resistance, and can withstand a certain load without breaking.
4. Easy processing and installation: Mullite insulated firebrick has good plasticity and machinability, can be cut, drilling and other processing according to needs, and installation is relatively easy.
