In this paper, the extrusionswell phenomena and mechanism for polymer melts from short dies are discussed.
讨论了聚合物熔体经短口型挤出时的胀大现象及机理。

The factors that affected extrusionswell of thermoplastic starch were optimized by response surface based on the single factor experiment.
在单因素试验的基础上,利用响应面分析法对影响热塑性淀粉挤出膨胀率的因素进行优化。

The result shows that the extensional flowing of the melt occurs in convergent die resulting in intense entrance elastic effect and distinct extrusionswell.
