摘　　要：PET生产线扩容改造后,对工艺控制过程中产品端羧基值发生波动时的工艺指标变化进行了分析,提出判断方法,建立非稳定状态下的对策,实现了产品端羧基值的稳定控制。After polyester production line capacity increasing modification, the process indexes change when product carboxyl end group value fluctuation during process control was analysed. The judgment methods were put forward. The countermeasures under unsteady conditions were established. Steady control of product carboxyl end group value was realized.
