In the thermal insulation of industrial furnaces, aluminum silicate fiber paper can effectively reduce heat loss in the following ways:

I. Low thermal conductivity

Aluminum silicate fiber paper has a very low thermal conductivity, usually between 0.03 and 0.17 W/m k. This low thermal conductivity makes it possible to effectively prevent heat from transferring from high temperature area to low temperature area, thus significantly reducing heat loss and improving energy utilization efficiency.

II. High-temperature thermal insulation performance

Aluminum silicate fiber paper can withstand high temperature up to 1300℃ and maintain stable heat insulation performance at high temperature. This high-temperature stability enables it to be used in the high-temperature environment of industrial furnaces for a long time without being deformed or damaged by high temperature.

III. Porous fiber structure

There are a lot of tiny pores in the fiber structure of aluminum silicate fiber paper, which can effectively block the heat transfer. This porous structure not only reduces the heat conduction path, but also reduces the heat capacity of the material, making the industrial furnace more energy-saving in the process of heating and cooling.

IV. Reducing the thickness of the furnace wall

Using aluminum silicate fiber paper as heat insulation material can significantly reduce the thickness of furnace wall. The thinner furnace wall not only reduces the heat transfer path, but also reduces the heat storage loss of the furnace body, further improving the heat insulation effect.

V. Sealing performance

Aluminum silicate fiber paper also has good sealing performance, which can be used to seal the expansion joint of furnace door and furnace body. By effectively preventing the leakage of high temperature gas, the heat loss is further reduced, and at the same time, the furnace structure is protected from high temperature erosion.

VI. Construction and installation convenience

Aluminum silicate fiber paper has good flexibility and machinability, and can be easily cut, folded and installed. This construction convenience enables the thermal insulation layer to closely adhere to the surface of the furnace body, ensuring the integrity and effectiveness of the thermal insulation layer.

VII. Significant energy-saving effect

Using aluminum silicate fiber paper as heat insulation material can significantly reduce the heat loss and energy consumption of industrial furnaces. For example, in some industrial furnaces, after using aluminum silicate fiber paper, the power saving can reach 38-40% and the power saving can reach 23-33%.

VIII. Chemical stability

Aluminum silicate fiber paper has excellent chemical stability and can maintain stable performance in harsh chemical environment. This enables it to be used for a long time in high-temperature equipment in chemical and metallurgical industries without being damaged by chemical corrosion.

Through the above methods, aluminum silicate fiber paper can effectively reduce heat loss, improve energy utilization efficiency and prolong the service life of equipment in industrial furnace insulation.
