毛细管流变仪测定PE100管材料黏度的两种方式

Two methods for determination of viscosity of PE 100 piping material by capillary rheometer

独山子石化公司生产PE100管材料期间,根据表观黏度值进行第一反应器和第二反应器生产比率的控制,调节管材料分子量大小及分布。测试表观黏度时所需要的试验压力可以通过口模入口处的压力传感器和柱塞上端的力值传感器这两种方式测量,本文讨论这两种测量方式的差异以及影响因素。

PetroChina Dushanzi Petrochemical Company uses apparent viscosity value to control the production ratio between the 1st reactor and 2nd reactor so as to regulate molecular size and distribution of piping material in production of PE100 piping material.The required test pressure for the determination of apparent viscosity can be measured by the pressure transmitter at the inlet of die or the force transducer at the top of the plunger.This paper deals with the difference and influence factors between them.
