摘要
针对废旧聚酯化学法回收主要经过醇解和再缩聚过程,采取在PET缩聚过程中加入着色剂的方法,通过测定每组产品切片的特性黏度、端羧基值、吸光度等指标,研究着色剂对PET再缩聚的影响。
Recycling of the waste PET used chemical method by alcoholysis and re-polycondensation process. In this paper,the colorant was added into the PET re-polycondensation process. The effects of colorants on PET re-polycondensation process were studied through testing the chip intrinsic viscosity,carboxyl end group value,absorbance of each sample.
