摘要
通过在聚丙烯(PP)体系中添加不同比例的回收料,采用多种分析方法,对聚丙烯新料及新料与回收料的混合料进行表征鉴定。结果表明,摩尔质量的变化、氧化诱导期、熔融结晶性能、熔体质量流动速率可以定性鉴别PP中是否添加了回收料。
By adding different proportions of recycled material in polypropylene （PP） system,the new and mixes of the new and recycled PP materials using different methods were characterized.The results showed that the changes of molecular weight,oxidation induction period,melt crystallization properties and melt flow rate can qualitatively identify whether there was recycled material in PP.
