polycrystalline fiberIs a polycrystalline alumina fiber. The content of Al2O3 in the fiber is between 72% and 75%, and the content of Al2O3 is above 80%, which is called polycrystalline alumina fiber.

The main crystal phase of polycrystalline fiber is a single mullite phase, in the polycrystalline nano alumina fiber through the use of high temperature, thermal stability development is better, is the use of more than 1400 working temperature products.

polycrystalline fiberpmf) is a relatively new ultra-light high-temperature refractory fiber at home and abroad. This is an all-al2o3-sio2 ceramic fiber. The use temperature is 1500-1700, higher than 200-400 glass fiber. Polycrystalline mullite fiber production enterprise technology development Zhejiang a company in March 1983 completed the Zhejiang Provincial Science and Technology Commission issued a "crystalline fiber through research" major impact research projects, is the first domestic institutions to obtain the technical evaluation. After years of efforts, with excellent production experience and reliable quality assurance, to provide technical advice, installation and construction of a series of after-sales service measures.

Polycrystalline fiber market listing, for the vast majority of design research staff can design new equipment, develop new products and new technology development provides a material basis; even for industrial and mining enterprises with thermal equipment to provide the transformation of old equipment, increase production, energy conservation, improve the environment, the progress of the ideal means.

polycrystalline fiberWhat is the scope of services?

Polycrystalline mullite fiber products can be used for long-term development of silicon carbide electric furnace, silicon molybdenum electric furnace, various Chinese steel heating furnaces, mechanical forging furnaces and other high-temperature thermal equipment below 1600, which can greatly improve the thermal efficiency of teaching equipment, greatly save resources and energy, improve the learning efficiency of management work, and improve the quality of their products and services.

Various high temperature industrial furnaces can be used as thermal insulation materials. Ceramic kiln system machinery for metallurgical heating furnace; heat treatment furnace and other national industrial production furnace open lining; high temperature and fire flame; kiln door, kiln car, expansion joint and other insulation structure materials; glass kiln insulation.

Polycrystalline mullite fiber is widely used in metallurgy, machinery, ceramics, electronics, petrochemical, aerospace and other thermal industry furnace and other thermal equipment lining and insulation. It can achieve the purpose of saving energy and increasing production, reducing the temperature difference in the furnace, improving the service quality of its own products, reducing the consumption of spare parts, prolonging the life of the furnace, and improving the management of the working and living environment. According to the scope of service, it can be divided into the following parts:

polycrystalline mullite fiber cotton

Polycrystalline mullite fiber single plate

polycrystalline mullite fiberboard

Polycrystalline mullite fiber molding products

Polycrystalline mullite fiber felt

Polycrystalline mullite fiber blanket

Polycrystalline mullite fiber module

Polycrystalline fiber is a fiber composed of high melting point metal oxide microcrystalline group. The main differences between polycrystalline fiber and ordinary refractory fiber (glass fiber, smooth surface fiber, aluminum silicate fiber, high aluminum fiber) are as follows:

Polycrystalline fiber alumina content (%) is greater than 72, the group is not fixed, stability (life) in the supply has become a material, is a more stable crystal structure, high temperature use after the same, long life. General fire resistance (life): the use of unstable state, the use of short cycle, the group structure for the glass state.
