Descripción de Producto

Special Mullite Light Weight Refractory Brick
The Description:

Mullite poly 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.

Mullite light insulation brick is a kind of refractory insulation material widely used in the emerging industrial kiln and high temperature equipment. With the increasing demand for energy conservation in the world, the development of light insulation materials has developed rapidly. Lightweight mullite brick is one of the ideal thermal insulation refractory materials at home and abroad, with good chemical stability, high temperature resistance, high dimensional accuracy, uniform structure, beautiful appearance, low thermal conductivity. Now widely used in hot blast furnace, glass crucible, metal furnace, ceramic tunnel kiln, roller kiln, electric porcelain shuttle kiln, etc., has broad market prospects.

Mullite brick product advantages
1, mullite brick due to its low thermal conductivity, so it has a good thermal insulation effect, in the construction process can make the thickness of the furnace wall thinner;
2, the impurities content of mullite bricks is low, especially the content of oxides such as iron and alkali metals is very low, so the refractorability of mullite bricks is high, and the high aluminum content makes it maintain good performance in the reduction atmosphere;
3, Mullite insulation brick high temperature compressive strength, maximize the strength and stability of masonry.
4, the appearance of mullite insulation brick size is the highest, can speed up the masonry speed, reduce the use of refractory mud, maximize the strength and stability of the masonry, thus extending the life of the lining;
5, mullite light brick is easy to process, can be processed into a special shape according to the needs of customers, thereby reducing the number of bricks and joints.
