Product introduction of JM30 insulation brick
The high temperature resistance of JM30 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.
Features of JM30 insulation brick
- Mullite insulating brick has high hot state compressive strength
- Low thermal conductivity, good thermal insulation effect
- Accurate appearance and size, accelerating masonry speed, reducing the use of refractory mud, ensuring the strength and stability of masonry, thus extending the service life of lining
Applications of JM30 insulation brick
JM30 insulation bricks are widely used in residue gasification furnace, secondary reformer of synthetic ammonia, carbon black reaction furnace, refractory kiln and other equipment. The overall dimensions, physical and chemical indexes and service life of the products meet the requirements of customers.
