aluminum silicate fiberAs a high temperature insulation material and refractory material has a long history, just started by a company in the United States, with natural kaolin as raw material, using resistance furnace melt injection technology, in 1943 began small-scale production. Since then, aluminum silicate fiber has been put into industrial production and developed rapidly.

In recent years, aluminum silicate fiber, as a kind of thermal insulation material, has been widely used in the preparation of new thermal insulation layer of thin layer composite materials, especially in aerospace and other thermal insulation components that require light weight and large space. This material is an ideal heat protection material and has been effectively used. The ensuing energy crisis has led to the rapid development of aluminum silicate fiber in the world, so it has received more and more attention.

Nowadays, more and more countries are engaged in the research and development of aluminum silicate fiber. Among them, the United States, Russia, Britain, Japan, etc. are in a leading position in this field, especially the United States. Due to its early research and advanced technology in this field, it has developed many varieties and is widely used in aerospace and other fields. For example, a company in the United States specializes in manufacturing high-purity aluminum silicate fiber paper, which does not require a binder. This kindaluminum silicate fiberPaper is mainly developed to meet the insulation requirements of spacecraft, end cover ablation protective layer, ignition device lining, oxygen generator and so on. Other aluminum silicate fiber composite products have been widely used in the thermal insulation layer of rocket engine parts, the ablation protective layer of the wing leading edge and end cover of military and high-purpose aircraft, the thermal insulation layer of exhaust duct, the fire protection layer of instruments and equipment, the thermal insulation layer of launcher, the thermal insulation layer of engine and personnel compartment, etc.

In recent years, foreign countries have increased the application of various ceramic fiber products in the steel and industrial furnace industries. Through practice, it is found that using ceramic fiber as furnace lining can save a lot of energy, and the energy saving range can reach 20% ~ 40%. At the same time, due to the light weight of ceramic fibers, the weight of industrial furnaces and steel structures can be reduced by about90%and70%. Later, due to the country's vigorous advocacy of energy conservation and emission reduction, aluminum silicate fiber and its products have been further developed. There are many kinds of aluminum silicate fiber products, such as aluminum silicate fiber board, aluminum silicate fiber felt, aluminum silicate fiber components, aluminum silicate fiber composite products are widely used in refractory insulation industry.

at present,aluminum silicate fiberIt has become a new type of thin-layer composite fiber insulation material. In addition, aluminum silicate fiber lining is widely used. According to the prediction of domestic experts, expanding the application field of aluminum silicate fiber lining to high temperature furnace lining can reduce the energy consumption of high temperature industrial furnace by more than 40%. Due to the successful development of polycrystalline fibers such as polycrystalline mullite fibers, the use temperature of aluminum silicate fiber products is increasing. Now, the use of ceramic fiber lining temperature can reach1600Degree. In addition, if a layer of high temperature resistant coating is continuously coated on the ceramic fiber furnace lining, its application range can be further expanded, the service life can be extended, and the use temperature can be increased1800Degree.
