Study on the Improvement of Surface Morphology of PAN-based Pre-oxidized Fibers
In view of the hot melt merging phenomenon between tow and monofilament and the problem of im-purity particles on the fiber surface in the production process of hot air circulating pre-oxidation furnace,direction-al transformation was carried out.The results show that the installation of air distribution device in the furnace cavi-ty of the pre-oxidation furnace can improve the uniformity of air volume and effectively solve the phenomenon of thermal melting and merging between the tow and the monofilament.In this way,the uniformity of the degree of pre-oxidation and the consistency of the properties of the carbon fiber are improved,so that the mechanical proper-ties of the final carbon fiber can be significantly improved.
