硬聚氯乙烯塑料简称PVC,具有优良的耐腐蚀性能,一定的机械强度,良好的焊接成型性能,便于加工和维修,因而广泛地应用于化工、石油、冶金、医药、染料等工业部门。早在1939年,德国由于缺乏耐蚀金属而使用硬聚氯乙烯塑料制作耐酸设备,英美等国也早已将硬聚氯乙烯塑料制作塔、贮槽、反应器等。1960年以后,我国也开始在化工生产中应用。硬聚氯乙烯塑料贮槽的形式和容积有以下几类:大型立式贮槽(300米~3)和球形贮槽(75米~3)仅个别单位使用;20米~3以下的立式贮槽和20～50米~3的卧式贮槽
It is widely used in chemical, petroleum, metallurgy, medicine, dye and other industrial sectors because of its excellent corrosion resistance, certain mechanical strength, good welding and forming properties, and easy processing and maintenance. As early as 1939, Germany used hard polyvinyl chloride (PVC) plastic to make acid-proof equipment due to the lack of corrosion-resistant metal. Britain, the United States and other countries also long ago made rigid PVC plastic towers, storage tanks and reactors. After 1960, our country also started to apply in chemical production. The form and volume of hard polyvinyl chloride plastic storage tank are as follows: Large vertical storage tank (300-3) and spherical storage tank (75-3) are used only for individual units; vertical Storage tank and 20 ~ 50 m ~ 3 horizontal tank
