高粘聚酯切片特性粘数测试方法的优化

摘要

针对高粘PET样品的特性,通过试验对比,对聚酯特性粘数分析测试方法中规定的样品粉碎时间及称样量进行了优化,得到了适用于高粘PET样品特性粘数测试的最佳测试条件。%In this paper,the sample′s smash time and quantity were optimized in the the method of PET intrinsic viscosity,the best test conditions of the test method of intrinsic viscosity suitable for the chips using for PET Strap were obtained.
