Among numerous refractory materials, high silicon fiber felt is like a shining star, attracting much attention. What are the characteristics that make it the preferred refractory material? Next, let's unveil the mysterious veil of high silicon fiber felt together.

Basic characteristics of high silicon fiber felt

High silicon fiber felt is a fiber felt material made from high-purity silicon dioxide through special processes. It has the characteristics of soft texture and light weight, which makes it very convenient to install and use. Compared with traditional refractory bricks and other materials, high silicon fiber felt can be cut and bent as needed, and can adapt to various complex shapes and structures.

From the appearance, the high silicon fiber felt presents a white and delicate color, with a uniform and smooth surface. Its fiber structure is dense and interwoven to form a stable network structure. This structure not only endows high silicon fiber felt with good flexibility, but also gives it excellent thermal insulation performance.

For example, in some small experimental furnaces, using high silicon fiber felt as the lining material can easily conform to the shape of the furnace wall, and due to its light weight, it will not add too much burden to the furnace body.

Excellent fire resistance performance

One of the most prominent characteristics of high silicon fiber felt is its excellent fire resistance. It can withstand high temperatures without melting or burning, and maintain stable performance even in high-temperature environments. Generally speaking, the operating temperature of high silicon fiber felt can reach over 1000 ℃, and some high-quality products can even withstand high temperatures of up to 1200 ℃.

This is due to its unique chemical composition and microstructure. High purity silicon dioxide has a high melting point, which makes high silicon fiber felt have good thermal stability at high temperatures. At the same time, its fiber structure can effectively prevent heat transfer and serve as insulation.

In the steel smelting industry, high-temperature furnaces are the core equipment for production. High silicon fiber felt is widely used in the lining of furnaces, which can effectively resist high temperature erosion, protect the furnace structure, and extend the service life of the furnace. For example, in a large steel plant, after using high silicon fiber felt as the furnace lining, the maintenance cycle of the furnace was significantly extended, greatly improving production efficiency and reducing production costs.

Good chemical stability

In addition to fire resistance, high silicon fiber felt also has good chemical stability. It can resist the erosion of various chemical substances, including corrosive substances such as acids and alkalis. In some chemical production processes, a large amount of corrosive gases and liquids are generated. Ordinary refractory materials are easily corroded and damaged, while high silicon fiber felt can maintain stability in such harsh environments.

This is because the silicon dioxide in high silicon fiber felt has strong chemical inertness and is not easily reacted with other substances. Meanwhile, its dense fiber structure can also prevent the infiltration of chemicals.

In the reaction vessel of a certain chemical enterprise, traditional refractory materials are quickly corroded due to the production of acidic gases and liquids, resulting in frequent maintenance of the reaction vessel. Later, high silicon fiber felt was used as the lining material, and after long-term use, the high silicon fiber felt remained intact, effectively protecting the reactor and reducing maintenance costs and downtime.

Efficient thermal insulation effect

The thermal insulation effect of high silicon fiber felt is also one of the important reasons why it has become the preferred refractory material. Its fiber structure contains a large amount of air, which forms tiny insulation units that can effectively prevent heat transfer. Compared with other refractory materials, high silicon fiber felt has a lower thermal conductivity, which can better maintain the temperature inside the furnace and reduce heat loss.

In industrial kilns, using high silicon fiber felt as insulation material can significantly reduce the energy consumption of the kiln. For example, in ceramic firing kilns, using high silicon fiber felt for insulation treatment reduces the energy consumption of the kiln by about 20%, while also improving the firing quality of ceramics.

In addition, the insulation effect of high silicon fiber felt is also reflected in its ability to quickly heat up and maintain a stable temperature. In some equipment that requires rapid heating, such as heat treatment furnaces, high silicon fiber felt can help the equipment quickly reach the required temperature and improve production efficiency.

Widely applicable fields

Due to its excellent properties, high silicon fiber felt has been widely used in many fields. In the industrial field, in addition to the steel smelting, chemical, ceramic and other industries mentioned earlier, it is also widely used in glass manufacturing, electronics, machinery and other industries. In the glass manufacturing process, high silicon fiber felt is used for insulation of glass kilns, which can improve the quality and production efficiency of glass. In the electronics industry, high silicon fiber felt is used in high-temperature testing equipment for electronic components to ensure the stability of the testing environment.

In the field of architecture, high silicon fiber felt also has certain applications. It can serve as a fireproof and thermal insulation material for buildings, improving their fire safety performance. For example, in the firewalls of some large commercial buildings, filling high silicon fiber felt can effectively prevent the spread of fire and buy time for personnel evacuation and fire rescue.

In the aerospace field, high silicon fiber felt is used for thermal insulation and protection of spacecraft due to its lightweight and high temperature resistance characteristics. It can withstand the heat generated by high-temperature friction when the spacecraft enters the atmosphere, protecting the safety of equipment and personnel inside the spacecraft.

In summary, high silicon fiber felt is undoubtedly the preferred refractory material due to its basic characteristics, excellent fire resistance, good chemical stability, efficient thermal insulation effect, and wide application fields. With the continuous development of technology, the performance of high silicon fiber felt will continue to improve, and its application prospects will also be broader.
