Product introduction of JM26 insulation brick
JM26 Mullite brick is light weight and has good insulation effect. It is high quality and high purity refractory powder. According to the required proportion of products, organic composite filler is added, formed by vacuum extrusion and sintered at high temperature.
Features of JM26 insulating bricks:
The high temperature resistance of mullite insulating bricks can reach above 1790 ℃. The load softening starting temperature is 1600-1700 ℃, the normal temperature compressive strength 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. And it can greatly reduce the weight of the high temperature furnace body, transform the structure, save materials, save energy, and improve the production efficiency.
