PE隔板的抗氧化性能及其机理的研究

Investigation on antioxidation and oxidation mechanism of PE-separators

介绍了超高分子量聚乙烯隔板应用及抗氧化问题,从原材料和氧化机理的角度对PE隔板的抗氧化性能进行了讨论。同时针对抗氧化性能的提高,通过实验检测、论述了抗氧化剂类型和油含量对隔板抗氧化性能的影响。通过扫描电镜,分析了隔板在电池中氧化的原因并对隔板将来的改进方向提出了建议。

This paper introduces the antioxidation of PE-separators,discusses it in the view of raw materials and the oxidation mechanism,and describes the effect of various kinds of antioxidants and oil content on the oxidation resistance of PE-separators.The reason for the oxidation of PE-separators has been analysed by the result of SEM testing and the approach to improvement of the separators has been proposed.
