摘要:聚烯烃是聚乙烯(PE)、聚丙烯(PP)等由碳氢化合物组成的聚合物的统称.随着上世纪50年代石油化工行业的蓬勃兴起和发展,聚烯烃管道材料因其耐腐蚀性、摩擦系数小、重量轻、易运输和安装,以及长达50甚至100年的使用寿命,已被广泛用于国内外的市政基础设施建设.然而,相比较传统的水泥、金属等管道,人们对聚烯烃管材的正确选择和使用了解较少,因此本文概述了聚烯烃管道材料的发展思路和历史,介绍了其在市政管道系统的最新应用,并提出了可持续发展的一些建议.%Polyolefin, including polyethylene and polypropylene, is polymer consisting of carbon and hydrogen. As the development of petrochemical industry after 1950's, polyolepn pipes have widely been used for infrastructural projects and municipal constructions. Their advantages are corrosion free, low friction coefficient, light, easy transportation and installation, particularly for more than 50 year lifetime. However, compared with traditional material, such as concrete, metal etc. , there is less understanding for polyolefin pipeline material selection and application. Therefore the recent development and application of polyolefin pipes were described, and suggestions for their sustainable development were given in this article.
