Fire resistance protection is crucial in industrial production. High silicon fiber felt, as a new type of refractory material, is gradually becoming an excellent partner for industrial fire-resistant protection. Next, let's delve into the relevant characteristics and applications of high silicon fiber felt.

Basic Overview of High Silicon Fiber Felt

High silicon fiber felt is made from high-purity silica as raw material through special production processes. It has a continuous fiber structure and presents a white felt like appearance. This fiber felt has a soft and elastic texture, is easy to process and cut, and can be made into various shapes and sizes according to different industrial needs.

From a chemical composition perspective, the content of silicon dioxide in high silicon fiber felt is usually over 96%, which gives it many excellent properties. Compared with traditional refractory materials, high silicon fiber felt has lower density and lighter weight, which has significant advantages in some industrial applications that require weight.

Fire resistance performance of high silicon fiber felt

The most prominent feature of high silicon fiber felt is its excellent fire resistance performance. It can withstand high temperatures of up to 1000 ℃ or even higher without melting or burning. In high temperature environments, high silicon fiber felt can maintain stable physical and chemical properties, effectively preventing heat transfer and providing good insulation.

For example, in the steel smelting industry, high-quality refractory materials are required for protection around high-temperature furnaces. High silicon fiber felt is widely used in the walls, roofs, and other parts of furnaces. Once there was a steel plant that used high silicon fiber felt to provide fire-resistant protection for the furnace, which not only reduced heat loss and improved energy efficiency, but also extended the service life of the furnace and reduced production costs.

In addition, high silicon fiber felt also has good thermal shock resistance. In the case of rapid temperature changes, it will not crack or peel off, and can always maintain its integrity and stability. This makes it perform well in some industrial processes that require frequent heating and cooling.

Chemical stability of high silicon fiber felt

High silicon fiber felt has good chemical stability and can resist the erosion of various chemical substances. It has strong resistance to corrosive substances such as acid and alkali, and can maintain its performance unchanged for a long time in some chemical production environments.

In the reaction vessels of chemical enterprises, various acid-base reactions are often involved. High silicon fiber felt can be used as insulation and protective materials for reaction vessels, effectively preventing corrosion of equipment by acidic and alkaline substances. A chemical company has significantly extended the service life of its reaction vessel by using high silicon fiber felt for protection, reducing equipment maintenance and replacement costs.

At the same time, high silicon fiber felt also has good antioxidant properties. In high temperature and aerobic environments, it does not undergo oxidation reactions and can maintain its original properties and structure. This has made it widely used in some high-temperature oxidation environments.

Application fields of high silicon fiber felt

The application fields of high silicon fiber felt are very extensive. In the metallurgical industry, in addition to the steel smelting mentioned earlier, it also has important applications in non-ferrous metal smelting. For example, in the process of aluminum smelting, high silicon fiber felt can be used for insulation and protection of electrolytic cells, improving electrolysis efficiency and reducing energy consumption.

In the ceramic industry, high silicon fiber felt can be used as the lining material for kilns. It can effectively reduce the heat loss of the kiln, improve the thermal efficiency of the kiln, and thus reduce the cost of ceramic firing. Meanwhile, due to its excellent thermal insulation performance, it can also make the temperature inside the kiln more uniform and improve the quality of ceramic products.

In the aerospace field, high silicon fiber felt is used for thermal insulation and protection of spacecraft due to its light weight and good fire resistance. For example, when a spacecraft returns to the atmosphere, it will generate intense friction with the air, resulting in extremely high temperatures. High silicon fiber felt can be used as a thermal insulation material for spacecraft shells, protecting the safety of equipment and personnel inside the spacecraft.

In the power industry, high silicon fiber felt can be used for insulation and insulation of equipment such as transformers and motors. It can effectively prevent damage to equipment caused by heat, improve the stability and reliability of equipment operation.

Development prospects of high silicon fiber felt

With the continuous development of industry, the requirements for fire-resistant protective materials are also increasing. High silicon fiber felt, as an excellent refractory material, has broad development prospects.

On the one hand, with the continuous advancement of technology, the production process of high silicon fiber felt will be continuously improved and perfected, and its performance will be further enhanced. For example, by optimizing the raw material formula and production process, the fire resistance temperature and thermal insulation performance of high silicon fiber felt can be improved, enabling it to meet more demanding industrial environmental requirements.

On the other hand, with the increasing awareness of environmental protection, higher requirements have been put forward for the environmental performance of refractory materials. High silicon fiber felt has the advantages of being non-toxic, odorless, and pollution-free, and meets environmental protection requirements. In the future, it will be promoted and applied in more fields.

In addition, with the continuous improvement of industrial automation, higher requirements have been put forward for the installation and use of fire-resistant protective materials. High silicon fiber felt has a soft texture, is easy to process and install, and can meet the needs of industrial automation production. This will also provide more opportunities for its development.
