Description of Ceramic Fiber Cotton
Ceramic fiber cotton is made of high-purity alumina-silicon dioxide components through twisting or blowing processes. These fibers can be further modified by grinding. Special lubricants can be added when necessary. Most of the loose ceramic fibers are used as the main raw material for the production of vacuum-formed products such as blankets, boards, and paper. The fibers are also widely used in the chemical industry and have a variety of uses.

Advantages of Ceramic Fiber Wool
Good resistance to high temperatures
Ceramic fiber wool is a high-temperature refractory material that can maintain the structural integrity and stability of the material in a high-temperature environment. It can withstand temperatures of up to 1400 ℃ or more and cope with extreme high-temperature conditions.
Good thermal insulation
Ceramic fiber wool has very low thermal conductivity, which can effectively isolate the temperature difference inside and outside of high-temperature equipment. Under high temperature conditions, it can effectively reduce heat transfer, ensuring the stability and safety of the equipment.
Good chemical stability
Ceramic fiber wool is able to resist corrosion under the influence of acid, alkali, water and other chemicals, has good chemical stability. Due to this, ceramic wool can be used in various aggressive environments, it is not easy to damage.
Lightness and softness
Ceramic fiber wool is light, soft and easy to process and install. This allows it to be used flexibly in some complex equipment designs to achieve optimal thermal insulation.
Application of ceramic fiber wool
Metallurgical industry
Ceramic fiber wool can be used for insulation of thermal furnaces, graphite furnaces, metal smelting furnaces and other high temperature equipment.
Chemical industry
Ceramic fiber wool can be used as insulation material for reactors, dryers, furnaces and other high-temperature installations in chemical industry.
Mechanical engineering
Ceramic fiber wool can be used as thermal insulation for engines, gas turbines and other high temperature components in mechanical engineering.
Electricity
Ceramic fiber wool can be used for thermal insulation of high-temperature devices such as pipelines, cables, furnaces, generators, etc. in the power industry.
Raw materials for ceramic fiber end products
In addition, ceramic fiber wool can also be used as a raw material for various ceramic fiber final products. The final products can be produced by molding, pressing, twisting, knitting and other processing methods of ceramic fiber wool.
