聚合物黏度压力敏感性测试方法的研究

Research Overview of Test Methods for Pressure Sensitivity of Polymer Melt Viscosity

综述了出口增压法、双柱塞法、拖曳流法3种方法在研究聚合物黏度压力敏感性方面的应用,分别介绍了3种方法的基本原理、测试装置的基本结构及研究成果,列举了3种方法的具体应用;提出了一种测试压力敏感性的新方法。

The article reviewed the applications of export pressurization method, double piston method and drag flow method for the study of pressure sensitivity of polymer melt and also introduced the basic principles and structures of experimental setup as well as the research results obtained from these three methods. Moreover, the specific applications of three methods were enumerated, and a new method for the test of pressure sensitivity was also proposed.
