Abstract

Microporous PE separators have gained large popularity in the lead acid battery industry, particularly in SLI (starting, lighting and ignition) automotive applications. The "PE" (polyethylene) in a battery separator is actually UHMW-PE (ultra high molecular weight polyethylene). UHMW-PE has a molecular weight more than ten times that of conventional HDPE (high density polyethylene). This paper gives an overview of the UHMW-PE's contributions to the PE battery separator process, assembly, and performance, in comparison to other conventional separators, such as PVC (polyvinyl chloride), cellulose, and glass fiber.

超高分子量聚乙烯在微孔聚乙烯分离器中的作用
微孔PE分离器在铅酸电池行业,特别是在SLI(启动,照明和点火)汽车应用中获得了很大的普及。电池隔膜中的“PE”(聚乙烯)实际上是UHMW-PE(超高分子量聚乙烯)。超高分子量聚乙烯的分子量是传统HDPE(高密度聚乙烯)的十倍以上。本文概述了UHMW-PE对PE电池隔膜工艺、组装和性能的贡献,并与其他传统隔膜(如PVC(聚氯乙烯)、纤维素和玻璃纤维)进行了比较。
