不同催化剂生产的聚丙烯力学性能比较

Compare of Mechanical Performance of Polypropylenes Produced by Different Catalysts

对分别使用841催化剂和TK催化剂生产的均聚丙烯(PP2401)和共聚丙烯(PP1330)两类聚丙烯四种材料进行拉伸试验、弯曲试验和冲击试验等三种测试,从测试结果比较四种材料间的力学性能差异,为国内聚丙烯生产厂家根据力学性能的不同要求选择不同催化剂进行生产提供一定的参考依据,并为国产催化剂的改良提供一定的信息.

In this paper, we perform experiments upon polypropylenes(PP2401) and co-polypropylenes (PP1330) that produced by 841-catalyst and TK-catalyst. The experiments are tension test, impact test and bending test. This paper compares the mechanical performance of different polypropylenes using the results of the experiments.
