Will light weight affect the effect of mullite brick?

Mullite Insulation Brick – This is one of the lightweight insulating bricks, which is made from high alumina bauxite clinker as the base material and a small amount of clay. The fire resistance of mullite brick is also very high, it can withstand high temperatures 1800 degrees Celsius, and its pressure resistance is also very high.

Glass industry

The consumption of mullite lightweight bricks in the glass industry is relatively high. It is often used as a refractory lining for glass furnaces., to resist thermal shock and chemical attack in high temperature glass melting areas.

Ferrous metallurgy

Ferrous metallurgy is also one of the important consumption areas of mullite bricks. In high temperature equipment, such as blast furnaces, converters and electric arc furnaces, муллитовые легкие кирпичи широко используются в огнеупорных футеровках для защиты от эрозии высокотемпературным расплавленным металлом и химическими газами.

Does the low weight of mullite brick affect the thermal insulation properties?

Mullite brick is lightweight, but this will not affect the thermal insulation functions. Low density results in lightness, but this does not affect its thermal insulation functions.

Advantages of lightweight mullite bricks

Lightweight mullite bricks are light in weight and load; they have low thermal conductivity, low melting and low impurity content. There are tiny air holes inside, which can guarantee, that the furnace wall loses less heat, and fuel costs are correspondingly reduced.

Are mullite insulation bricks afraid of water??

Lightweight mullite brick itself is not afraid of water, can be used in damp environments, and also has certain waterproof characteristics. However, if the installation surface of the insulating brick is incorrectly treated, this will cause water to leak and penetrate the insulation layer, what will affect the insulation effect. Therefore, in the process of design and construction of engineering thermal insulation systems, it is necessary to strictly follow the requirements of the specification, especially when sealing a joint. At the same time, for mullite light bricks, who have been in a humid environment for a long time, long-term use may also cause aging or deformation, and they need to be replaced promptly.
