Brief introduction of JM26 insulation brick
As an excellent refractory raw material, JM26 mullite insulating brick is a mineral formed from high-temperature aluminosilicate with relatively few such minerals. Mullite can prepare various types of heat insulation bricks, which have good heat insulation effect and have been successfully applied in many industries.
Features of JM26 insulation brick
- High strength
- High temperature resistance
- Low thermal conductivity
- High thermal shock resistance
Applications of JM26 insulation brick
JM26 mullite insulating bricks are mainly used for hot blast furnace roof, blast furnace chips, furnace seat, glass furnace storage room, ceramic sintering furnace, etc.
