Audited Supplier Mullite Insulating brick is also known as light mullite brick or mullite thermal insulation brick, mullite thermal insulation brick is made of high quality bauxite clinker as the main raw material, plus an appropriate amount of clay, ingredients and water mixed to make plastic mud or mud, extrusion molding after high temperature fired high-quality thermal insulation brick.
Mullite insulation brick is mullite (3Al2O3·2SiO2) as the main crystalline phase of high alumina refractory, the general alumina content between 40% and 75%, mineral composition in addition to mullite, which contains low alumina also contains a small amount of glass phase and cristobalite, containing high alumina also contains a small amount of corundum.

Product characteristics:
1)due to the low thermal conductivity characteristics of mullite insulation brick, light mullite brick has a good thermal insulation effect;
2)Mullite insulation brick has the characteristics of low hot melt and low thermal conductivity, can store little heat energy, so the energy saving effect is very obvious in intermittent operation;
3) low impurity content has a very low iron box oxide content such as alkali metal, so the fire resistance is high, and the high aluminum content makes it maintain good performance in the reduction atmosphere;
4)Mullite insulation brick high temperature compressive strength, to ensure the strength and stability of masonry.
5) the appearance of mullite insulation brick size is accurate, can speed up the masonry speed, reduce the use of refractory mud, ensure the strength and stability of the masonry, thus extending the life of the lining;
6) mullite light bricks are easy to process, can be processed into special shapes according to the needs of customers and drawings provided by customers, thereby reducing the number of bricks and joints.
Company main products and profiles:
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
