Product introduction of mullite insulation brick JM28
As an excellent refractory raw material, mullite insulating brick is a mineral formed from high-temperature aluminosilicate with relatively few such minerals. Mulite can prepare various types of heat insulation bricks, which have good heat insulation effect and have been successfully applied in many industries.
Features of mullite insulation brick JM28
The advantages of mullite insulation bricks are high purity, less impurities, high temperature resistance, direct contact with flame, resistance to various atmospheric corrosion, low thermal conductivity, low hot melting, high strength, excellent thermal shock resistance, high dimensional accuracy, and free cutting. It acts on the high-temperature furnace to directly contact the flame, with good heat preservation effect, high pressure resistance, low thermal conductivity, etc.
