Description

Technical Field

[0001] The present invention relates to the technical field of carbon fiber, and specifically to a sizing mechanism for carbon fiber. Background Art

[0002] Carbon fiber refers to a fiber in which the carbon element in the chemical composition of the fiber accounts for more than 90% of the total mass. Due to the nature of carbon itself, the production and manufacturing conditions of carbon fiber are very harsh. Generally, the production process of carbon fiber mainly includes the preparation of raw silk, the oxidation of raw silk, the carbonization or further graphitization of pre-oxidized fiber, and the post-treatment of carbon fiber. In the above-mentioned entire production and processing process of carbon fiber, the last step of the post-treatment of carbon fiber is often overlooked because its impact on the quality of carbon fiber itself is relatively small and the difficulty is relatively low compared with the previous processes, resulting in relatively backward post-treatment technology and equipment for carbon fiber. The post-treatment of carbon fiber mainly includes two aspects, one is the surface treatment process of carbon fiber, and the other is the sizing process. The main purpose of the sizing process is to prevent carbon fiber from fuzzing and damage and increase its service life. The sizing process is to immerse the carbon fiber after surface treatment into a protective sizing solution so that a protective layer is coated on the surface of the carbon fiber, thereby achieving the purpose of preventing carbon fiber from fuzzing and damage and relatively increasing the service life of carbon fiber.

[0003] In the existing carbon fiber sizing mechanism, the solvent in the sizing solution is easy to precipitate and not easy to size, reducing the sizing effect of carbon fiber and having poor practicability.
