JM Mullite Insulation Brick for Sale
Description
Mullite insulation brick is a kind of lightweight refractory insulation brick. JM mullite brick is made of high quality high alumina bauxite clinker as the main raw material, adding appropriate amount of clay, auxiliary materials and water to make plasticized mud or slurry, and then made by a special process. Mullite insulation bricks are characterized by light weight, excellent thermal insulation performance, good refractory performance, corrosion resistance, high temperature stability, environmental protection and so on.
Features
Excellent thermal insulation properties
Mullite insulation bricks have a very low thermal conductivity, which can effectively isolate high-temperature heat sources and protect the surrounding environment from high temperatures.
Good corrosion resistance
JM mullite insulation brick has good resistance to acid and alkali corrosion, can be used for a long time in acid and alkali corrosive environment without damage.
High temperature stability
Mullite insulating brick has excellent high-temperature stability, can withstand thermal stress at high temperatures, long-term use without deformation, no cracking.
Good mechanical strength
JM mullite insulated brick has good mechanical strength, can withstand high temperature, high pressure and other harsh environments of mechanical stress.
Good wear resistance
JM mullite thermal insulation brick has good wear resistance, can be used in high temperature, high pressure and other harsh environments for a long time without wear and tear.
Light weight
Mullite heat preservation bricks have low density, usually in the range of 0.6-1.2g/cm³, which is much lighter in weight and easy to handle and install.
Environmentally friendly, non-toxic and harmless
JM mullite insulation bricks are made of high-purity mullite and special glass phases, which do not contain harmful substances and meet the requirements of environmental protection, and are harmless to human beings and the environment.
