Ceramic fiber blankets are respirable, and they are harmful to the environment and the human body. Some foreign companies have strengthened restrictions on the use of amorphous ceramic fibers.
At present, a kind of bio-soluble amorphous ceramic fiber appears in the market of heat-resistant refractory materials. This super fiber (siO2-CaO-MgO series ceramic fiber) is a pollution-free and environmentally friendly material.
The future production trend of ceramic fiber blankets is to develop in the direction of pollution-free, refinement and multifunctionality. High-temperature glues especially use new processes and new materials to prepare high-value-added, high-tech functional fine ceramic fibers. The probability will become larger and larger, which is of great significance for optimizing thermal insulation refractories.
