聚酯切片软化初峰温度与干燥时间和温度的关系

RELATIONSHIP BETWEEN SOFTING POINT OF PET CHIP AND THME OR TEMPRATIURE USE TO DRY THE CHIP

通过测试在不同干燥温度和时间下聚酯切片软化初峰温度的变化，初步探讨了半消光切片软化初峰温度与干燥时间和干燥温度的关系，同时为干燥装置提供了适宜的操作条件。

By measring the chang of the softing point under the different temperature and for drying, thearticle make preliminary study on relationship between softing point of Semi-dull PET chip and thetemperature or time used to dry the chip. The study can provide the information to set operation conditionof drying unit.
