扭转振荡式黏度计的调校维护及故障处理

Calibration and Maintenance of TOV Viscometer

在聚酯切片连续生产过程中,黏度控制地好坏直接影响成品质量,一旦发生黏度超标,产品质量就会降等,造成严重的经济损失。根据扭转振荡式(TOV)黏度计原理,掌握正确调校、维护经验数据和方法,以实现快速判断和处理TOV黏度计故障,确保特性黏度控制稳定的目的。

In the process of continuous production of polyester chips, the viscosity control has a direct impact on the quality of finished products. If the viscosity exceeds standards, the product quality will be degraded, resulting in serious economic loss. This paper introduces the experience data and methods in correct adjustment and maintenance of viscometer based on the principle of viscometer, so as to to achieve rapid judgment and treatment of viscometer failure, and ensure the stability of the intrinsic viscosity control.
