高密度聚乙烯膜料熔体质量流动速率测试程序优化

Optimization of test program for melt mass flow rate of high density polyethylene film

为解决生产的高性能膜料在熔体质量流动速率测试过程中精密度差的问题,通过多组试验,得出更适合这种材料的测试方法,提高了测试数据准确度,能够更加合理的表征材料性能。

In order to solve the problem of poor precision in the process of testing the melt mass flow rate of high performance membrane materials,a test method more suitable for this material was obtained through several groups of tests,which improved the accuracy of the test data and could more reasonably characterize the material properties.
