Refrigeration Diagnosis of Large-diameter Conduct Pipe for Medium by WAIM

水辅助注塑大直径介质导管制品的冷却分析

First , WAIM model was introduced , and then the elements and their relationship of web accessibility were analyzed .

首先，对WAIM模型进行了介绍，并结合我国国情对网站无障碍建设相关联的各要素及其相互关系进行了分析。

On the other hand , WAIM involves processing parameters in terms of melt temperature , water temperature , water inlet pressure , etc. which directly influence rheological properties of polymer , material distribution and molding quality .

而且涉及到诸如熔体温度、注水温度、注水速率等工艺参数，都直接影响着聚合物熔体的流变性能、材料分布和制品质量。

Therefore it ’ s necessary to conduct research on water penetration mechanism and influence of processing parameters on molding quality , which provides helpful guidance for the production.According to process characteristics , simulation for filling process of WAIM is implemented based on Hele-Shaw flow model with general Newtonian fluid equations involved .

因此有必要针对水辅助注射成型穿透机理与工艺参数对成型质量的影响规律展开研究，从而更好地指导生产实践。本文根据水辅助注射成型的工艺特点，基于Hele-Shaw流动模型采用广义牛顿流体本构方程，对水辅助注射成型的充填过程进行数值模拟研究。
