Description

technical field [0001] The invention relates to a multi-spinning carbon fiber precursor winding device, which belongs to the technical field of carbon fiber processing equipment. Background technique [0002] Carbon fiber is an inorganic polymer fiber with a carbon content of more than 90%. In addition to the high temperature resistance, friction resistance, corrosion resistance, and electrical and thermal conductivity of general carbon materials, it also has softness, machinability, light weight, and high specific strength. characteristics, thus being widely used in many fields such as military, textile, sports equipment, chemical industry, medical equipment and mechanical processing. [0003] The preparation process of polyacrylonitrile carbon fiber includes raw material polymerization, turning spinning, washing, drying and densification, pre-oxidation, carbonization, sizing and drying, etc. After the carbon fiber precursors have been washed, dried and densified, they nee...

Problems solved by technology

However, on the one hand, the method of reducing static electricity cannot completely avoid the generation of static electricity, and static electricity may still be generated during the winding process; on the other hand, adding metal oxides to the fiber will have a certain impact on the properties of the carbon fiber itself, and even Limiting the use of carbon fiber

At the same time, the use of metal guide rollers or general-purpose insulating ceramics has an unsatisfactory effect of eliminating static electricity, and cannot solve the problem of high hairy rate of fiber precursors
