Glass fiber cloth refractory fiber

Refractory fiber can also be called ceramic fiber and aluminum silicate fiber. Ceramic fiber is the main representative of refractory fiber in a broad sense. It is a general term for refractory fibers such as alumina, silica, aluminum silicate and zirconia. It also includes carbon fiber, nitride fiber, boride fiber and non-oxide fiber. In a narrow sense, only aluminum silicate melted or sol-fibrillated fibers are called ceramic fibers, which are different from other fibers. In the narrow sense, the ceramic fresh fiber is to take out the melt formed by Al, O, Si0, in the state of thin stream, and then make it fibrillated by blowing and spinning. This method is called the melt fibrosis method. Glass fiber, rock wool, slag wool, etc. are basically the same as their production methods, but their performance is different due to the composition of raw materials. The biggest difference in performance is the use of warm friction. For refractory fibers, the long-term use temperature is 1000"1250C and the melting temperature is above 1780C. The continuous use temperature of rock wool and slag wool is 600"700, and the continuous use temperature of glass wool (alkali-free glass wool) is less than 380C , Fibrous filaments will shrink and shatter sharply beyond their service temperature. For this reason, these materials cannot be used as worki
