Ceramic fiber is a kind of fibrous lightweight refractory material, which has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical vibration resistance, so it is widely used in machinery, metallurgy, chemical industry, petroleum, ceramics, Glass, electronics and other industries have been widely used. In recent years, due to the continuous rise of global energy prices, energy saving has become China's national strategy. In this context, ceramic fibers, which can save 10-30% energy compared with traditional refractory materials such as insulating bricks and castables, have received more energy in China. More and wider applications, the development prospects are very promising.
Ceramic fiber is made by double-sided needle punching process. It is a spinning blanket, and the other is a spinning blanket.
1. The diameter of the fiber filament: the spinning fiber is thicker, the spinning fiber is generally 3.0-5.0 microns, and the spinning fiber is generally 2.0-3.0 microns;
2. The length of the fiber filament: the spinning fiber is longer, the spinning fiber is generally 150-250mm, and the spinning fiber is generally 100-200mm;
3. Thermal conductivity: Spinning blankets are better than spinning blankets because of their finer fibers;
4. Tensile and flexural strength: the spinning blanket is better than the spinning blanket due to the thicker fibers;
5. The application of making ceramic fiber blocks: the spinning blanket is better than the spinning blanket because the fibers are thicker and longer. It can be folded very tightly and not easily damaged, and the quality of the block will directly affect the quality of the furnace lining;
6. Vertical layering application of large blankets such as waste heat boilers: The spinning blanket has better tensile strength and durability due to the thick and long fibers, so the spinning blanket is better than the spinning blanket.
