What are the functions of polycrystalline mullite fibers?

I. The role of polycrystalline mullite fiber

1. High temperature stability

One of the remarkable properties of polycrystalline mullite fibers is their high-temperature stability. This material is able to maintain the stability of physical and chemical properties in high temperature environments of more than 1500 ° C, making it an ideal heat insulation and thermal insulation materials for high temperature industrial processes.

2. Thermal shock resistance

In environments where temperatures change rapidly, the thermal shock resistance of the material is a key factor in ensuring the stable operation of the equipment. Polycrystalline mullite fiber can withstand rapid temperature changes without rupture, thanks to its excellent thermal stability and microstructure flexibility.

3. Lightweight and efficient heat insulation

Polycrystalline mullite fibers have a low thermal conductivity, which makes them very efficient in terms of thermal insulation. At the same time, due to its fibrous structure, the material has a lower density than conventional refractory materials, which reduces the weight of the structure and improves energy efficiency.

4. Good chemical stability

In addition to its high-temperature properties, polycrystalline mullite fibers are chemically stable and resistant to a wide range of chemicals, including acids and alkalis. This characteristic makes it widely used in the chemical industry in the field of heat insulation, thermal insulation and corrosion prevention.

5. Easy to process and install

Polycrystalline mullite fiber can be made into products of different shapes and sizes, such as blankets, boards, paper, etc., which makes it possible to be cut and installed according to the specific needs of the application, providing great flexibility and convenience.

Second, the application areas of polycrystalline mullite fiber

1、Metallurgical industry: used as heat insulation and lining material for furnace body to improve thermal efficiency.

2、Aerospace: used for thermal insulation protection of high temperature components and systems.

3、Ceramics and glass manufacturing: to provide thermal insulation and temperature equalization of the furnace.

4、Chemical industry: used as thermal insulation for reactors and pipelines while preventing chemical corrosion.

5、Electric power industry: used for thermal insulation of flue and other components in thermal power plants.
