PET液相增黏釜清洗系统

The cleaning system of PET liquid-phase tackifying kettle

对PET液相增黏釜清洗系统进行介绍,分析了乙二醇蒸气清洗液效果不佳的原因。介绍了用三甘醇清洗PET液相增黏釜应用工艺路线、操作方法等。采取三甘醇和乙二醇组合的方式清洗液相增黏釜,废丝率大幅降低,产品品质也有较大的提升,提高了增黏釜的有效使用率,更大程度地完善了PET液相增黏技术。

The cleaning system of PET liquid-phase tackifying kettle was introduced. The reasons for the poor clean- ing effect of EG steam were analysed. The process route and operation methods of the application of TEG cleaning to PET ligid-phase tackifying kettle were introduced. By using the EG and TEG compound mode to clean the liquid- phase taekifying kettle, the waste rate can be reduced significantly, the product quality can be greatly improved, the effective utilization of the tackifying kettle was increased, the liquid-phase tackifying techifying technology was im- proved in a greater extent.
