Ceramic fiber products have the characteristics of high temperature resistance, small volume density, good insulation, good chemical stability, good thermal shock resistance, good resistance to wind erosion, easy construction and rapid construction, which are the most potential energy saving and environment-friendly insulation materials in the world. In fact, the most important characteristics of ceramic fiber are high strength, high modulus, low thermal conductivity and very good heat resistance. It can be used continuously at high temperature, and it can be used in some occasions to be even up to 1800%. The particularity of ceramic fibers is closely related to fiber composition and processing technology.
The manufacturing method of 2. ceramic fiber
Ceramic fiber substrate is thermally fused to form semi-finished ceramic products, and then processed into a uniform and fine a aluminum base fiber after 1300 degrees of heat treatment. It has been reported that the method of producing aluminum based ceramic fiber by Sumitomo chemical company has been reported in the market by using a chelated aluminum zirconium base material and polycrystalline aluminum / zirconium fiber. The method is to produce PAO by dissolving the aluminized platform with water, and mixing the silicon containing compound with PAO. The obtained compound is spinning under the condition of 28% and about 35% humidity. This fiber.
Finally, after calcination to obtain a fine basic fiber ceramic fiber. The continuous ceramic fiber based on silicon carbon was studied by Carbon company in Japan in 1981. The name of the product is Nicalon. There are also some other ceramic fiber manufacturing methods, such as Nicalon carbon silicon fiber high temperature manufacturing method, the carbon fiber company"s ceramic fiber manufacturing method and so on. One of the technological routes is to dissolve the superfine ceramic powder in the mixture of water and polyvinyl alcohol, and then press into the fine spinneret to produce the billet, and then the high temperature roasting, that is, the ceramic fiber is made.
