超高分子量聚乙烯的成型工艺及改性研究进展

Ultrahigh Molecular Weight Polyethylene Modeling Process and Modification

本文介绍了超高分子量聚乙烯材料的基本性能,并由其性能决定的成型工艺,由于超高分子量聚乙烯熔体粘度极高,加工比较困难,限制了其的应用;通过综述近年来的超高分子量聚乙烯的改性研究进展,认为只有进行有力的改性研究,才可以将超高分子量聚乙烯的优异性能得到更为广泛研究和应用。

This paper presents the outstanding performances of ultrahigh molecular weight polyethylenen （ UH- MWPE） and all kinds of its modeling processes. Because of the extremely high viscosity of the UHMWPE and the difficuky in its processing, the application field of the material is unavoidably restricted. The recent modification on UHMWPE have been reviewed, analysis result shows that with the development of the methods of molding and processing, UHMWPE will be used in more and more new fields.
