Polyester produced by chemical fiber enterprises, here it is
Thread Content
Hello, experts. It is understood that almost all polyester production lines pay close attention to the esterification rate, which is generally determined through laboratory analysis; however, this method has the drawback of a time lag. If it’s possible to conduct online detection of the esterification rate, do you think it would be useful as a guide for production?
It’s meaningless. The esterification rate is related to several production parameters such as vacuum level and viscosity; it is sufficient to monitor these parameters during production. Laboratory test data is a post-hoc method for analyzing quality and correcting processes.

Hello, the detailed information has been sent to your email; please check it
The production process is stable, and it is generally easy to control
Buy a densitometer; it measures the esterification rate without causing pain, and takes into account differences in density
Online density monitoring should be feasible
It’s meaningless. Generally, the feed pipeline for ester II is equipped with a flow meter, and density can also be measured; the esterification rate can be determined based on this density. The analyzed data is for reference only
