Discussed thoroughly the extrusion swell phenomenon and mechanism of polymer melts in conical die with different entrance angles and different ratios of length to diameter.
深入讨论了聚合物熔体在不同长径比、不同角度圆锥口模的挤出胀大现象及机理。
The velocity field and shear rate distribution are reduced and uniform along with the proper increase of slip length. The die swell and the interface deflexion phenomenon will be reduced effectively.
适当增加流道的长度，可以减小胶料出口处的速度场、剪切速率场的集中程度并使之趋于均匀，能够有效降低挤出胀大和模外熔体偏转流动现象。
