利用在线粘度监测提高聚合反应的工艺水平

IMPROVING THE PROCESSING LEVEL OF POLYMERIZATION WITH IN-LINE VISCOSITY MONITORING

介绍最近美国某聚酰胺生产厂在在线粘度计监测下,提高聚合反应工艺水平的方法。实际应用表明,在线粘度计的应用可以提高产品产量、质量和工艺效益,减少废品。该项技术可以推广应用于聚酯、醇酸树脂、丙烯酸树脂、聚氨酯、聚烯烃和聚苯乙烯等产品的生产。

A method improving the polymerization efficiency with in-line viscosity monitoring used by an American polyamide producer is introduced. With the new method, operators saw a continuous plotted curve that tracked viscosity over time. Viscosity is an accepted indicator of molecular weight. The key to this system is that there is no guesswork about the endpoint.
