Historical Development and Prospect of Ceramic Fiber Insulation

Ceramic Fiber Insulation materials are widely used in thermal insulation and high-temperature resistant materials of various thermal kilns. Because their bulk density is much lower than other refractory materials, the heat storage is very small and the heat insulation effect is obvious. As a furnace lining material, it can greatly reduce the energy loss of thermal kilns and bring a revolution to thermal kilns in terms of energy saving. Next, let us understand the historical development and prospects of Ceramic Fiber Insulation. Here are some answers.

History development.

Ceramic fibers appeared in 1941. The American Babu and Wilcox companies used natural kaolin and melted and blew them into fibers in an electric arc furnace. In the late 1940s, two companies in the United States produced aluminum silicate series fibers and applied them to the aerospace industry for the first time. In the 1960s, a variety of ceramic fiber products were developed in the United States and used in industrial furnace wall linings. In the 1970s, ceramic fiber began to be produced and used in my country, and its application technology was rapidly promoted in the 1980s, but the main applicable temperature range was below 1000℃, and the application technology was relatively immature. After entering the 1990s, with the popularization and application of chain fibers and polycrystalline alumina fibers, the use temperature of ceramic fiber insulation materials increased to 1000 ℃ ~ 1400 ℃. However, due to product quality defects and backward application technology, the application fields and application methods are limited. Although the use temperature of ceramic fiber insulation has been increased, the strength is very poor, which limits the scope of use and shortens the service life. Zirconium-containing fiber is a kind of aluminum silicate fiber with a wide range of uses and low cost produced by the melting method. It can be widely used as a hot-face full-fiber lining for building various thermal kilns. At present, the quality of domestic products in this regard and application development has yet to be further developed.

Prospect.

Although Ceramic Fiber Insulation materials play an important role in thermal insulation and fire resistance in high-temperature industrial fields. At present, a kind of bio-soluble amorphous ceramic fiber has appeared in the thermal insulation refractory material market. This super fiber is a non-polluting and environment-friendly material. The future production trend of Ceramic Fiber Insulation products is to develop in the direction of pollution-free refinement and multi-functionality. In particular, the use of new processes and new raw materials to prepare functional fine ceramic fibers with high added value and high-tech content will increase the production probability, which will be of great significance for optimizing thermal insulation and refractory materials.
