Ceramic fiber is made by double-sided needle punching process. It is widely used in both high temperature and low temperature environment. According to different production processes on the market, we generally divide ceramic fiber blankets into two categories, one is Spinning silk blanket, one kind is spinning blanket.
1. The diameter of the fiber yarn: the spun silk fiber is thicker, the spun silk fiber is generally 3.0-5.0µm, and the spinneret fiber is generally 2.0-3.0µm;
2. The length of the fiber yarn: the spinning fiber is longer, the spinning fiber is generally 150-250mm, and the spinning fiber is generally 100-200mm;
3. Thermal conductivity: Spinning blanket is better than spinning blanket due to the thinner fiber;
4. Tensile and flexural strength: Spinning blankets are better than spinning blankets due to thicker fibers;
5. Application of making ceramic fiber blocks: spun silk blankets are better than spin blankets because of the thicker and longer fibers. In the folding process of the block making, the blown fiber blankets are easy to break and tear, while spun silk fiber blankets It can be folded very tightly and not easily damaged. The quality of the block will directly affect the quality of the furnace lining;
6. Vertical layer application of large blankets such as waste heat boilers: because the fiber filaments are thick and long, the thrown silk carpet has better tensile strength and is more durable, so the thrown silk carpet is better than the spinneret blanket;
