超高分子量聚乙烯纤维的生产技术和市场分析

介绍了超高分子量聚乙烯(UHMWPE)纤维的主要生产方法,对干法纺丝和湿法纺丝工艺路线进行了比较;分析了国内外UHMWPE纤维的生产现状、市场需求及预测;从工艺路线、生产规模及产品质量方面比较了国内外UHMWPE纤维产品之间的差距;指出干法纺丝工艺路线是今后UHMWPE纤维的主要生产技术,我国应加大干法纺丝工艺的研发力度,尤其是十氢萘的回收技术,提高单机产量,实现规模化生产。

Production technology and market analysis of ultrahigh-molecular weight polyethylene fiber

The dominant production technologies for ultrahigh-molecular weight polyethylene(UHMWPE) fiber were introduced.The dry spinning process and wet spinning process were compared.The production status,market demand and forecast of UHMWPE fiber were analyzed in China and abroad.The gap between China and international UHMWPE fibers was analyzed from the aspects of process technologies,production scale and product quality.It was pointed out that dry spinning process should be the dominant production technology for UHMWPE fiber in the future,and China should enhance the research of dry spinning process,particularly decalin recovery technology,increase the single line output and realize the scale production.
