Description

technical field [0001] The invention relates to the field of new material production equipment, in particular to a carbonization device for producing carbon fibers. Background technique [0002] Carbon fiber is a new type of high-strength, high-modulus fiber material with a carbon content of more than 95%. And the obtained microcrystalline graphite material. Carbon fiber is soft on the outside and rigid on the inside, lighter than metal aluminum, but stronger than high-speed iron, and has corrosion resistance characteristics. It is an important material for lighting in national defense, military and civilian use. It not only has the inherent properties of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fibers. [0003] In the production process of carbon fiber, PAN precursor is mainly used as the main material, and it is obtained through some processing procedures such as pre-oxidation, carbonization, ...

Problems solved by technology

The whole carbonization process can be divided into two stages: low-temperature carbonization and high-temperature carbonization. The temperature of the former is generally 300-1000 degrees Celsius, and the latter is 1100-1600 degrees Celsius. It is easily oxidized by oxygen in the external air, which affects the production quality of carbon fiber. Not only that, during the carbonization process, due to various reactions, ammonia, water vapor, carbon monoxide, carbon dioxide, hydrogen cyanide and part of nitrogen are released. Impurities are easy to form tar and adhere to the surface of the fiber, affecting the cleaning and production and processing of carbon fiber, thus reducing the practicability of the existing carbon fiber oxidation device
