聚合物流体拉伸流变测量技术的进展

摘要

Four measuring techniques of extensional rheological parameters for polymer fluids that are mostly used in recent years, which include Meissner-type rheometer(RME), modified rotational rheometer(MRR), filament stretching rheometer(FSR), and Sentmanat extensional rhcometer (SER)are introduced. Their structure principles, development trends and problems within applications are analyzed and summarized.%介绍了近年来应用较广的4种聚合物流体拉伸流变测量技术:Meissner拉伸流变技术(RME)、改进旋转流变技术(MRR)、纤维撕扯流变技术(FSR)、Sentmanat 拉伸流变技术(SER),分析和总结了它们的结构原理、发展趋势和应用中存在的问题.
