Product introduction of JM26 insulation insulation brick
JM26 mullite insulation brick can withstand the high temperature above 1790 ℃. The starting temperature of filler softening is 1600-1700 ℃, the normal temperature withstand voltage is 70-260MPa, the thermal shock resistance is good, the strength is high, the high temperature creep rate is low, the expansion coefficient is low, the thermal coefficient is small, and the acid slag corrosion resistance is good.
Features of JM26 insulation insulation brick
- Mullite insulating brick is heat-resistant and pressure resistant
- Low thermal conductivity, good thermal insulation effect
- The mullite insulating brick has poor heat fusibility. Due to low thermal conductivity, mullite series lightweight insulating bricks have small heat storage capacity and obvious energy-saving effect during intermittent operation
Applications of JM26 insulation 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.
