In the field of high-temperature industry, high silicon fiber felt is widely used. In the process of ceramic firing, it is necessary to heat the ceramic body to a high temperature for sintering. High silicon fiber felt can be used as an insulation material for the kiln to reduce heat loss and improve the thermal efficiency of the kiln. At the same time, it can also serve as a supporting material for ceramic bodies to prevent deformation at high temperatures. In the glass manufacturing industry, high silicon fiber felt can be used for insulation of glass furnaces, reducing energy consumption and improving the quality of glass.

In the chemical industry, high silicon fiber felt can be used as insulation and anti-corrosion materials for equipment such as reaction vessels and pipelines. In the field of petrochemicals, many chemical reactions need to be carried out under high temperature and high pressure conditions. High silicon fiber felt can effectively protect equipment and prevent damage due to high temperature and chemical corrosion. In addition, it can also be used for the treatment of chemical waste gas as a filtering material to remove harmful substances from the waste gas.

In the electronics and power industries, the high insulation and low thermal conductivity of high silicon fiber felt make it an ideal insulation and thermal insulation material. It can be used for insulation of equipment such as transformers and motors, improving the safety and reliability of the equipment. Meanwhile, in the manufacturing process of electronic chips, high silicon fiber felt can be used as a heat dissipation material to help the chips dissipate heat in a timely manner and ensure their normal operation.

The role of high silicon fiber felt in the field of environmental protection

High silicon fiber felt also plays an important role in the field of environmental protection. In terms of air pollution control, it can be used as an efficient filtering material for the purification and treatment of industrial waste gas. For example, in the exhaust emissions of enterprises such as steel plants and cement plants, there is a large amount of dust and harmful gases. High silicon fiber felt can effectively filter these pollutants and reduce pollution to the atmospheric environment.

In terms of sewage treatment, high silicon fiber felt can be used as an adsorbent material to remove heavy metal ions and organic pollutants from sewage. It has a large specific surface area and good adsorption performance, which can quickly and effectively adsorb harmful substances in sewage. In addition, high silicon fiber felt can also be used for soil remediation, improving soil quality by adsorbing and fixing pollutants in the soil.
