Ceramic fiber is a fibrous lightweight refractory material with advantages such as high temperature resistance, light weight, low thermal conductivity, good thermal stability, low specific heat, and resistance to mechanical vibration. Therefore, it has been widely used in industries such as machinery, ceramics, glass, metallurgy, chemical, petroleum, and electronics. Due to the continuous rise in global energy prices in recent years, energy conservation has become a national strategy. Against this backdrop, ceramic fibers, which can save up to 10-30% energy compared to traditional refractory materials such as insulation bricks and castables, have been widely used in China, and their development prospects are very promising.
Ordinary ceramic fiber is also called Aluminium silicate fiber. Because one of its main components is aluminum oxide, which is the main component of porcelain, it is called ceramic fiber. Adding zirconia or chromium oxide can further increase the usage temperature of ceramic fibers.
Ceramic fiber products refer to industrial products made from ceramic fibers as raw materials, which have advantages such as good thermal stability, low thermal conductivity, light weight, high temperature resistance, low specific heat, and resistance to mechanical vibration. They are used in various high-temperature, high-pressure, and easily worn environments.
Ceramic fiber products are an excellent refractory material. It has the advantages of light weight, high temperature resistance, small heat capacity, good insulation performance, good high-temperature insulation performance, and non-toxicity.
The production process of ceramic fibers with a classification temperature of 1425 ℃ (including zirconium fibers) and below can only be divided into two types: silk spinning blankets and blowing blankets.
Main purpose:
1. Sealing of furnace doors and curtain curtains for various insulated industrial kilns.
2. Protective clothing, gloves, headsets, helmets, boots, etc. in high-temperature environments.
3. High temperature insulation and insulation of petrochemical equipment, containers, and pipelines.
4. High temperature flue, lining of air ducts, expansion joints.
5. The insulation cover of the car engine, the wrapping of the exhaust pipe of the heavy oil engine, and the composite brake friction pad of high-speed racing cars.
6. Thermal insulation, insulation materials, and brake friction pads used in the aerospace and aviation industries.
7. High temperature electrical insulation.
8. Fireproof joint products such as fire doors, fire curtains, fire blankets, spark pads, and thermal insulation covers.
9. Sealing fillers and gaskets for pumps, compressors, and valves that transport high-temperature liquids and gases.
10. Insulation and wrapping of cryogenic equipment, containers, and pipelines.
11. Thermal insulation and fireproof partitions for important places such as archives, vaults, and safes in high-end office buildings, as well as automatic fire curtains for fire protection
