衣架型模头内流道参数的确定和优化

Determination and Optimization of Flow Channel Parameters of Coathanger Type Die

根据聚合物加工流变学理论 ,采用衣架型单流道模头计算公式确定了模头的流道参数并加以优化 ,然后设计出适用于HDPE平膜的衣架型宽幅模模头尺寸。

Based on rheological theory of polymer processing, the parameters of flow channel are determined and optimized using calculation equation of single flow channel of coathanger type die. Then coathanger type wide-web film die is designed for HDPE flat film extrusion.
