軽量化はムライトレンガの効果に影響しますか?

Mullite insulation brick is one the lightweight insulation bricks, which is made of high-alumina bauxite clinker as the main material and a small amount of clay. The refractoriness of mullite bricks is also very high, it can withstand the high temperature of 1800 摂氏, and its pressure resistance is also very high.

Application of mullite brick

ガラス産業

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

鉄鋼業

The iron and steel industry is also one of the important consumption fields of mullite brick. In high-temperature equipment such as blast furnaces, コンバーター, and electric arc furnaces, mullite lightweight bricks are widely used in refractory linings to resist the erosion of high-temperature molten metal and chemical gases.

Does the light weight of mullite brick affect the insulation function?

The mullite brick is light in weight, but it will not affect the insulation function. The low density leads to the lightweight, but it does not affect its heat insulation function.

Advantages of lightweight mullite bricks

Lightweight mullite bricks are light in weight and light in load; they have low thermal conductivity, low heat fusion, and low impurity content. There are tiny air holes distributed inside, which can ensure that the furnace wall loses less heat, and the cost of fuel will be reduced accordingly.

Are mullite insulation bricks afraid of water?

Mullite lightweight brick itself is not afraid of water, can be used in humid environments, and also has a certain waterproof performance. しかし, if the installation interface of the insulation brick is not properly handled, it will cause water to leak and penetrate the insulation layer, thereby affecting the insulation effect. したがって, in the process of thermal insulation engineering design and construction, it is necessary to strictly follow the requirements of the specification, especially to seal the interface. 同時に, for mullite lightweight bricks that have been in a humid environment for a long time, if they are used for a long time, aging or deformation may also occur, and they need to be replaced in time.
