MulliteInsulationBrickSuppliers
Mullite insulation bricks use super mullite (3Al2O3鈥?SiO2) as the main crystal
phase, and the Al2O3 content is 42%-72%. The operating temperature can reach
1250鈩?1600鈩? Mullite insulation bricks are widely used in hot surface refractory
lining or thermal insulation layer of various thermal equipment due to its light
weight and excellent thermal insulation performance. Performance Characters of
Mullite Insulation Bricks 1. Low thermal conductivity, and good thermal
insulation effect. 2. Low heat melting, good energy saving effect. 3. Low
impurity content, high fire resistance; the high aluminum content makes it keep
good performance in reducing atmosphere. 4. High thermal compressive strength.
5. Accurate appearance dimension. Application of Mullite Insulation Bricks
Mullite insulation bricks are widely used in different types of high temperature
furnaces or kilns. For example, it is widely used for hot-blast furnace,
regenerative chamber of glass melting furnace, ceramic kiln, blind angle furnace
lining of petroleum cracking system, shuttle kiln, roller kiln and petrochemical
burning pits and so on. Mullite Insulation Bricks:JM23JM26JM28JM30
