由于塑料下水管道有许多优点:耐酸、耐碱、、耐腐蚀,管壁光滑,流动阻力小;重量轻,减轻工人劳动强度;光洁美观,省去铸铁管道油漆工序、缩短工期,安装操作方便,有利于文明施工。因此,我国从六十年代起,在长春、四平等地建筑工程公司已在民用、住宅下水道中逐步试用了塑料下水道,从而打破了近百年来一直采用铸铁管及配件的局面。目前,北京、山东、江苏、上海、浙江等省市分别生产塑料下水管和管件,并在当地民用建筑中逐步推广应用。特别是今年五月四日至五月九日,国家科委化学建材专业组在上海召开了民用建筑用塑料 As plastic sewer pipes have many advantages: acid, alkali, corrosion resistance, smooth wall, small flow resistance; light weight, reduce labor intensity of workers; clean and beautiful, eliminating the need for cast iron pipe painting process, shorten the construction period, easy installation and operation, It is conducive to civilized construction. Therefore, since the 1960s, in China, Changchun and Siping Construction Engineering Company have gradually tested plastic sewers in residential and residential sewers, thus breaking the situation in which cast iron pipes and fittings have been used for nearly 100 years. At present, Beijing, Shandong, Jiangsu, Shanghai, Zhejiang and other provinces and cities produce plastic water pipes and fittings, and they are gradually applied in local civil buildings. In particular, from May 4th to May 9th this year, the State Science and Technology Commission Chemical Building Materials Professional Group held a plastic for civil building in Shanghai.
