聚乙烯

The flow properties of the polypropylene and polyethylene were studied using Archimedes spiral and square spiral melt fluidity test molds, which had the same shape of cross section but different cavity profiles, and then relationship between melt flow ratio and cavity profile was analyzed.

摘 要：对聚丙烯和聚乙烯 2种塑料在阿基米德螺旋线与方形螺旋线流动性测试模具中的流动性能进行研究，分析塑料流动比与型腔轮廓特征的关系；引入修正系数β，对流动比校核公式进行修正。
