Crystal fiber manufacturersCompared with non-oxide fibers such as carbon fiber and silicon carbide fiber, polycrystalline mullite fiber not only has high strength, high modulus and high temperature resistance, but also has good high temperature oxidation resistance, corrosion resistance and electrical conductivity. Polycrystalline mullite fiber can be combined with resin, metal or ceramic to prepare high-performance composite materials, which are widely used in aviation, aerospace, military and high-tech fields.

　　Crystal fiber manufacturersSaid that the production process of polycrystalline mullite fiber is simple and does not require high production equipment and conditions. Compared with carbon fiber, the cost of this product is much lower, which makes a large number of applications of alumina fiber possible. At present, many companies have produced various types of high-performance alumina fibers.

Polycrystalline mullite fiber is mainly used for high temperature thermal materials (short fiber) and reinforced composite refractory (long fiber), can be woven into non-woven fabrics, braided belts, ropes and other shapes of fiber products.

With the further development of energy-saving technology, more and more attention has been paid to the investment of energy-saving measures. The material of masonry kiln is one of the important factors of energy saving and consumption reduction, which affects the heat consumption rate and service life of the kiln. Polycrystalline mullite fiber is a new type of ultra-light heat-resistant material in the world. It is composed of mullite microcrystals, which combines the characteristics of crystal materials and fiber materials, and has good thermal stability. The long-term use temperature can reach 1500, the melting point can reach 1840, the thermal conductivity is 1/6 of the traditional refractory brick, and the bulk density is only 1/25 of the traditional refractory brick. It can be widely used in industrial furnace lining heating.

In recent years, with the continuous improvement of the prosperity of the high-temperature refractory fiber industry, some "three noes" manufacturers or companies with no production capacity, no quality assurance and no after-sales service have begun to appear in the market. Some heat treatment users do not know enough about polycrystalline mullite fibers and their application risks and safety. Through the network publicity and other means, to low-cost way to induce heat treatment users, the low temperature resistant products as high temperature resistant products.

Crystal fiber manufacturers said that the production process control requirements of polycrystalline mullite fiber are relatively high, including precise control of process data such as gel and sol, fiber forming, hot air temperature, material pressure, rotation, drying, medium temperature heat treatment, high temperature heat treatment temperature and time, otherwise the fiber lining will shrink, pulverize, crack and peel off, causing fire.

　Crystal fiber manufacturersRemind everyone that polycrystalline mullite fiber is a white fiber-like lightweight refractory material. If it is not a professional visual, it is difficult to distinguish its material and temperature resistance. Some "three no" manufacturers or companies violate the principle of good faith management and use fake and shoddy materials. The actual temperature and use effect can not meet the requirements.
