Types and properties of ceramic fibers.

The varieties of ceramic fiber mainly include ordinary aluminum silicate fiber, high aluminum silicate fiber, aluminum silicate fiber containing zirconium, polycrystalline alumina fiber and polycrystalline mullite fiber. In recent years, foreign countries have successfully developed (or are developing) some new ceramic fiber varieties, such as magnesium olivine fiber, ceramic fiber (SiO Cao MgO system and Al, o-cao, etc.), ceramic fiber cotton, felt, blanket, module, paper, cloth, belt, rope, etc

Ceramic fiber blanket (fiber module) is mostly made of long fiber by self melting, continuous melting and continuous throwing production process. The fiber is interwoven by double-sided needling. It can be directly used as the hot surface of flame, integrating fire resistance, heat insulation and heat preservation. It can be used in neutral, oxidizing and partial reducing atmosphere for a long time. It can still maintain good strength and toughness. The fiber module made of this fiber blanket does not contain binder and has good thermal stability. It is widely used in petrochemical, metallurgical, electric power and other heat preservation and heat resistance fields.

Ceramic fiber board is made of ceramic fibers, adhesives and additives through pulping, forming, curing, drying and other processes. Ceramic fiber board is flexible, easy to cut, and has high strength. It is a new energy-saving and environmental protection product with low thermal conductivity and low heat storage. It is widely used in various heating equipment, wall, roof and other parts of the backing. It is a heavy refractory material, ceramic fiber cloth. It is mainly used in fire doors and industrial kiln insulation, Thermal insulation of high-temperature pipes and vessels, ceramic fiber ropes are mainly used for expansion joints of various industrial kilns, winding and thermal insulation of high-temperature pipes, thermal insulation of steel structure joints, etc.
