Ceramic fiber is known for its stability at high temperature .It is available in several forms for your refractory needs , like ceramic fiber blanket , cermaic fiber board, ceramic fiber module or special shapes .Characterisitics include lightweight , low thermal conductivity and heat storage as well as corrosion resistant .this product family provides proven and effective solutions to a variety of heat processing applications



    Ceramic fiber is widely used in various types of thermal insulation of high temperature insulation materials, because of its bulk density is much lower than other refractory materials, and thus a small heat storage, insulation effect is obvious, as the lining material can greatly reduce the thermal furnace Energy loss, in the energy-saving aspects for the thermal furnace has brought a revolution. On the other hand, its application techniques and methods also bring about a change in the masonry of the thermal kiln.



    Use the status quo

    Ceramic fiber first appeared in 1941, the United States Babu Weier Cox company with natural kaolin, by the arc furnace melt into the fiber. In the late 1940s, the two companies produced aluminum silicate fiber and used it for the first time in the aviation industry. In the 1960s, the United States developed a variety of ceramic fiber products and used in industrial furnace lining. In the 1970s, ceramic fiber began to be used in our country, and its application technology was rapidly promoted in the 1980s. However, the main use temperature range is below 1000 ℃, and the application technology is relatively simple and backward.



    After the 1990s, with the promotion of zirconium fiber and polycrystalline alumina fiber application, the use of temperature increased to 1000 ℃ ~ 1400 ℃, but due to product quality defects and application technology backward, application areas and application methods are subject to Limited. Such as: polycrystalline alumina fiber can not be made into fiber blanket, the product specifications to single cotton, fiber blocks, although the use of home appliances insulation temperature has increased, but the intensity is poor, limiting the use of the scope, but also shorten the service life The



    Zirconium fiber is produced by the melting method of a wide range of uses, low cost of aluminum silicate fiber can be used as a large number of masonry a variety of thermal furnace full-fiber furnace lining, the current domestic product quality in this area And application development is still relatively backward, and now there are chrome-containing fibers abroad, the use of higher temperature than the zirconium fiber.

Type and use

    Ceramic fiber varieties are: ordinary aluminum silicate fiber, aluminum silicate aluminum fiber, aluminum silicate fiber, polycrystalline alumina fiber and polycrystalline mullite fiber. In recent years, foreign countries have successfully developed some new varieties of ceramic fiber, such as: ceramic fiber. Ceramic fiber products are mainly: ceramic fiber cotton, ceramic fiber felt, ceramic fiber blanket, ceramic fiber module, ceramic fiber paper, ceramic fiber cloth, ceramic fiber belt, ceramic fiber rope and so on.

    Ceramic fiber blanket (fiber module): the use of self-melting, even the melting of the production process made of long silk spinning, the double-sided acupuncture fibers made of intertwined, can be directly as a hot flame, set fire Heat, insulation in one, in the neutral, oxidizing and partial reductive atmosphere in the long-term use, can still maintain a good strength, toughness. The fibrous module made of this fiber blanket does not contain bonding agent, good thermal stability, widely used in petrochemical, metallurgical, power and other heat insulation field.

    Ceramic fiber board: ceramic fiber and binder, additives, through the pulp, molding, curing, drying and other processes made. Ceramic fiber board is flexible, easy to cut, high strength, is a low thermal conductivity, low heat storage of new energy-saving environmental protection products, widely used in a variety of heating equipment, the top of the wall, the top part of the backing, is a heavy refractory.

    Ceramic fiber cloth, with: mainly used in fire doors, industrial furnace insulation, high temperature pipes and containers of insulation.

    Ceramic fiber rope: mainly used in a variety of industrial furnace expansion joints, high temperature pipe winding insulation, steel structure, such as the junction of insulation.
