EFFECT OF OILING CONTROL ON PRODUCTION COST AND QUALITY OF CARBON FIBRE PRECURSOR

Yu Bo, Qiao Ruibo

ABSTRACT:In the production of carbon fibre industry, oiling of carbon fibre precursor can impart fibre smoothness, antistatic property, and bundling property, and also allows the precursors to have sufficient high temperature resistance, fibre splitting, and melting resistance; therefore, the oiling control has a crucial effect on the production cost and quality of carbon fibre precursors. This paper discusses the oiling methods of carbon fibre precursors by using the oil roller and circulation pump of oil groove, besides, the defects of these two methods in practice were also analysed. Thus, the oiling methods above were further improved and changed to be the oiling tank for oil groove. Finally, it is concluded that the excellent oil control method, combined with good finish oil proportioning and experienced operator control, can depress the adverse effects of oil on carbon fibre precursors, solve the oil defects, and reliably improve the performance of carbon fibre precursors; the reliable oil control enables the oil to achieve an ideal oiling effect, ensuring the stability, continuity and homogeneity of various indicators in the production of carbon fibre precursors.
