1*40HQ conatiner of Insulation Ceramic Fiber Blanket &Insulating mullite bricks &Insulating castables are packed for delivering to our customer in Peru.

Insulating mullite brick is mainly a high alumina refractory material with the main crystal phase of mullite (3Al2O3·2SiO2), and the alumina content is generally between 65% and 75%. It is made of high bauxite clinker with a small amount of clay. According to the density of different classification, is divided into light mullite insulation brick and heavy mullite insulation brick, according to the use of different temperature, is divided into 1350 mullite brick, 1450 mullite insulation brick, 1550 mullite brick, 1550 mullite brick, etc., more than 1550 mullite brick is generally used as a fire cellar bricks, because of the high temperature of heat resistance.

Characteristics of insulating mullite brick:
1, low thermal conductivity, with good heat insulation effect;
2, Low hot melt, due to low thermal conductivity, mullite series light insulation bricks store little heat energy, energy saving effect is obvious in intermittent operation;
3, low impurity content has a very low content of oxides such as iron box alkali metal, therefore, high refractory; The high aluminum content makes it maintain good performance in reducing atmosphere.
4, hot state high compressive strength;
5, the appearance of the size is accurate, speed up the masonry, reduce the use of refractory mud, to ensure the strength and stability of the masonry, so as to extend the life of the lining;
6, can be processed into a special shape, to reduce the number of bricks and joints.
Usage: mullite insulation brick can be directly used in high temperature kiln lining, has been widely used in shuttle kiln, roller kiln, glass and petrochemical kiln lining.
