摘要
介绍了提高聚酯切片干燥效果的几点措施。通过对BM干燥除湿系统的改进,由原来氯化锂转轮除湿,改为分子筛除湿,并对分子筛的再生温度及再生时间、预结晶的加热温度、主干燥的加热温度等工艺参数进行探讨,确定了聚酯切片干燥的最佳工艺参数。
Some measures for improving dryness of the polyester chip are introduced. Through improvement of BM dry system, molecur sieve type moisture is substituted for Licl type moisture. The craft parameters of mole cular sieve such as heating temperature working time, heating temperature of crystal, heating temperature of drying etc are also discussed. The best drying craft parameter of the polyester chip is confirmed.
