Description

technical field [0001] The invention relates to a carbon fiber production method, which belongs to the technical field of carbon fiber production. Background technique [0002] Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%. Its high temperature resistance ranks first among all chemical fibers. The production process of carbon fiber includes unwinding, thread collection, drying, oxidation, low-temperature carbonization, high-temperature carbonization, surface treatment, and water washing. , sizing and collecting steps. [0003] During the sizing process, the slurry needs to be evenly attached to the surface of the carbon fiber, and the traditional impregnation method usually takes a long time to impregnate completely, which is a waste of time; usually, the carbon fiber needs to be dried after sizing, and the traditional process Among them, sizing and drying need to be carried out in two devices, which is a waste of time; usuall...

[0003] During the sizing process, the slurry needs to be evenly attached to the surface of the carbon fiber, and the traditional impregnation method usually takes a long time to impregnate completely, which is a waste of time; usually, the carbon fiber needs to be dried after sizing, and the traditional process Among them, sizing and drying need to be carried out in two devices, which is a waste of time; usually, when the electric push rod is connected to other parts, it is usually connected in a fixed way. When the parts connected to the electric push rod need to be When rotating, a rotating structure has to be added on the surface of the parts, which will lead to more part structures and more troublesome maintenance in the later stage; moreover, the traditional limiting plate does not have the function of reducing friction. When friction occurs, it will have a certain impact on the equipment to a certain extent
