Mullite Insulating Refractory Brick JM23 JM26 JM28 High Working Temperature Wall Insulation Types
Mullite Insulating Refractory Brick JM23 JM26 JM28
Mullite Insulating Refractory Brick JM23 JM26 JM28 made by CH refractories is JM series according to international
standard.
Because JM23 JM26 JM28 insulation brick with smaller bulk density
whose strength is not as strong as heavy weight fire bricks, when
delivering, CH Refractories will package mullite insulating brick
with special packages to protect mullite bricks from damage.
Mullite insulating brick is a new type of lightweight mullite
bricks with 50-80% Al2O3, mullite (3Al2O32SiO2) as main crystalline
phase and binder phase. JM23 JM26 JM28 insulation brick is widely
used for working face inner lining that contact flame directly
because high temperature stability and high strength, low thermal
expansivity and good thermal shock resistance. Mullite insulating
brick became one of the research focuses recent years. Mullite
insulating brick adopts high-purity raw materials and unique
production process to minimize the influence of impurities and
structural defects on the performance of the product. Mullite
insulating brick adapts to various furnace types and different
construction environment well. Mullite insulating brick is high
level insulation products for kiln and furnace, which can be used
for higher temperature insulating layer than common insulating
bricks.
In order to make sure safely deliverying of insulation brick, CH Refractories pay a great attention on the package, we put several pieces mullite insulation into a paper carton and then put on the pallet, make sure there is no any damage to the bricks when shipping in the contaiers.
