PET熔体品质黏度的影响因素及控制

Influence factors and control of PET melt quality viscosity

从生产实际出发,对PET黏度的影响因素如反应温度、真空度、停留时间、搅拌转速、浆料密度变化、催化剂进行了简要分析,介绍了控制PET黏度稳定的关键措施。

Starting from the actual production, the influence factors on PET viscosity such as reaction temperature, vacuum degree, residence time, agitation speed, slurry density change and catalyst was analyzed briefly. The key measures to control PET viscosity were introduced.
