主要侧重于从元素组成角度对聚氯乙烯产品特性作了研究与讨论。介绍了聚氯乙烯产品含氯高的组成特点具有重要工业意义之常识;分析了聚氯乙烯是廉价塑料品种之原因;解释了聚氯乙烯是难燃塑料品种之原因;探求了聚氯乙烯是具有抗生物降解和防虫蚀之原因;也介绍了聚氯乙烯含氯高所产生的其它影响和不同于一般聚烯烃的不良特性。
It mainly focuses on the research and discussion on the characteristics of PVC products from the perspective of elemental composition. The common features of the compositional characteristics of high chlorine content in PVC products are introduced. The reasons why PVC is a low-cost plastic variety are analyzed. The reason why PVC is a kind of flame retardant plastic is explained. Has anti-biodegradable and anti-erosion causes; also introduced other high chloride-containing PVC produced by the impact and different from the general characteristics of polyolefin poor.
