Carbon fiber production process capable of simultaneously performing washing and sizing treatment

Abstract

The invention discloses a carbon fiber production process capable of simultaneously carrying out washing and sizing treatment, and particularly relates to the technical field of carbon fiber production. The carbon fiber production process specifically comprises the following steps of S1, yarn withdrawing, yarn collecting and drying treatment, S2, pre-oxidation carbonization treatment, and then machining surface treatment, and S3, washing, drying, sizing, re-drying treatment and yarn collecting. The invention relates to the technical field of carbon fiber production. According to the carbon fiber production process capable of simultaneously carrying out washing and sizing treatment, washing and sizing treatment procedures can be combined for simultaneous treatment, the purpose of conveniently and efficiently carrying out washing and sizing treatment on carbon fibers is well achieved, the production efficiency is greatly improved, the workload of production personnel is relieved, the site space is saved, a large number of rollers do not need to be adopted to widen the line width, the cost is low, the side-by-side design is well adopted to save more space, the water washing cost is reduced through the water washing pool bottom winding design, and therefore use by people is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of carbon fiber production, in particular to a carbon fiber production process capable of simultaneous water washing and sizing treatment. Background technique [0002] Carbon fiber refers to high-strength and high-modulus fibers with a carbon content of more than 90%. Excellent material, with high temperature resistance, anti-friction, electrical conductivity, thermal conductivity and corrosion resistance. High strength and modulus, the carbon fiber production process includes: unwinding, thread collection, primary drying, primary pre-oxidation, secondary pre-oxidation, three pre-oxidation, low-temperature carbonization, high-temperature carbonization, primary surface treatment, secondary surface treatment, Water washing, secondary drying, sizing, tertiary drying and wire collection, among which water washing and sizing are important post-treatment processes for prefabricated carbon fiber filaments, and bo...

AI Technical Summary

Problems solved by technology

[0011] Aiming at the deficiencies of the prior art, the present invention provides a carbon fiber production process capable of washing and sizing at the same time, which solves the problem that the existing carbon fiber production equipment cannot realize the combination of washing and sizing processes for simultaneous treatment, and the cleaning effect is still not good. The impurity with strong adhesion on the surface of carbon fiber cannot be fully cleaned, and the failure rate of sizing is high, so it cannot be realized. The design of ordinary dipping and vertical line taking is adopted to make the slurry on the fiber uniform in value on the surface of the fiber. Flow to ensure uniform sizing
