Method of Study on Extensional Viscosity of Polymer Melts

聚合物熔体延伸粘度的研究方法

The extensional viscosity when polymer solution passing the size-varing pores is considered into Darcy viscosity, rebuilding the effective viscosity model in the Darcy Law.

把聚合物溶液通过拉伸&收缩的孔道时所表现的拉伸粘度，考虑到达西粘度中，重新建立了达西公式中的有效粘度模型。

The relations between extensional viscosity and Hencky strain, strain rate and temperature are observed.

从熔体拉伸时瞬时拉伸粘度与应变、应变率的关系以及温度的影响，观察聚合物熔体拉伸变化规律。

For PPU1780F1, the extensional viscosity is higher and the elasticity is lower, so it is suitable for spunbonded nonwovens.

PPU1780F1拉伸粘度高、弹性小，适用于纺丝成网非织造布专用聚合物。

The results show that the extensional viscosity of polymer melts changes with Hencky strain and strain rate.

实验结果表明：聚合物熔体拉伸粘度随应变、应变率而改变。
