       在通用树脂生产中,以PVC树脂耗乙烯量低,生产成本也低。国内生产每吨PVC需耗乙烯0.5314吨,而每吨聚乙烯平均耗乙烯1.042吨,国内每吨PVC树脂的乙烯耗量比聚乙烯少消耗约50%。而生产PVC用的原料氯气,是平衡生产烧碱产生氯气的重要途径,烧碱是国民经济必不可少的十分重要原料。另外,从塑料制品角度看,PVC与各种助剂相容性好,在生产管材中可加入大量低廉的填料,使生产成本大大降低。
 
In general resin production, PVC resin has the lowest ethylene consumption and the lowest production cost. The domestic production of PVC per ton of ethylene is 0.5314 tons, while the average ethylene consumption per ton of polyethylene is 1.042 tons. The consumption of ethylene per ton of PVC resin per ton is less than 50% less than that of polyethylene. The production of chlorine used in PVC is an important way to balance the production of caustic soda to produce chlorine. Caustic soda is a very important raw material for the national economy. In addition, from the perspective of plastic products, PVC has good compatibility with various auxiliaries, and a large number of cheap fillers can be added to the production pipes, which greatly reduces the production cost.
     
       PVC管材与金属管材相比,生产每立方米PVC和生产每立方米钢及铝计算,钢的能耗为316KJ/m3,铝的能耗是619KJ/m3,PVC的能耗为70KJ/m3,即钢的能耗是PVC的4.5倍,铝的能耗是PVC的8.8倍。而生产PVC管的加工能耗也仅为同口径金属管材的三分之一。同时由于PVC管壁光滑,不结腐蚀瘤,输水效率高,用于输液可节电20%左右。
 
Compared with metal pipe, PVC pipe and metal pipe, production per cubic meter of PVC and production per cubic meter of steel and aluminum calculation, the energy consumption of steel is 316KJ/m3, the energy consumption of aluminum is 619KJ/m3, the energy consumption of PVC is 70KJ/m3, that is, the energy consumption of steel is 4.5 times of PVC, and the energy consumption of aluminum is 8.8 times that of PVC. The energy consumption of producing PVC pipe is only 1/3 of the same caliber metal pipe. At the same time, because the PVC tube wall is smooth, does not corrode the tumor, the water delivery efficiency is high, for the infusion can save electricity about 20%.
 
PVC管材有很好的力学性能,且具备极好的耐腐蚀性,使用过程中重量轻,安装方便,不需维护,而使用钢铁作公用工程的下水管道,在使用过程中由于易腐蚀,必须经常涂敷涂料,维护费用高。一般建筑及公用工程用金属管道20年左右就需更换,而作用加工良好的PVC管道,使用寿命长达50年等。因此,PVC管材是一种生产成本低、强度高,耐腐蚀的良好塑料制品。
 
PVC pipe has good mechanical properties, and has excellent corrosion resistance. It has light weight, easy installation and no maintenance in the process of use. In the process of using steel as a utility pipeline, the coating must be often coated and the maintenance cost is high because of easy corrosion. For general construction and utility engineering, metal pipes need to be replaced in about 20 years, and the well functioning PVC pipes will last for 50 years. Therefore, PVC pipe is a good plastic product with low production cost, high strength and corrosion resistance.
 
一般来讲,在排污、废水和通风管道方面,PVC管道比使用铸铁管节约安装和劳务费用约16-37%;作导线管比使用金属导线套管节约费用30-33%;而作用氯化聚氯乙烯(PVC)管在冷热水方面,比使用相同尺寸的铜管节约费用为23-44%。因此,由于PVC管材的优势,各国均在积极发展和推广PVC管材
 
Generally speaking, in the aspects of sewage, waste water and ventilation pipe, the PVC pipeline saves about 16-37% of installation and labor cost than using cast iron pipe; it saves 30-33% for the use of metal wire bushing for traverse tube; and the effect of chlorinated polyvinyl chloride (PVC) tube in cold and hot water is 23-44% compared to the cost of copper tube with the same size as using the same size. Therefore, due to the advantages of PVC pipes, all countries are actively developing and promoting PVC pipes.
