摘要

高分子材料在管材生产领域逐渐代替金属等成为最重要的原材料，仅通过改变高分子化学结构，添加玻璃纤维、碳纤维等材料共混的方式来提高管材性能已经不能满足要求。本研究以杂萘联苯聚芳醚树脂(PPESK)为研究对象，对挤出机常用的机头进行了修改，加入类似吹膜原理的环向增强装置来提升管材强度。利用Ansys-Polyflow软件对设计机头的环向扩张效果进行模拟和分析，在扩张角度为30°时，具有合适的环向扩张速度分量为3.51 cm/s，此时熔体仍能保持很好的流动速度，没有产生明显的涡流和滞留。环向扩张速度可以使熔体内的分子链偏离原来的流动方向形成沿轴向的取向分布，增大管材环向抗压能力。

Abstract

Polymer materials have gradually replaced metals as the most important raw materials in the pipe production industry

leading to increasingly stringent requirements for pipe quality. However

improving pipe performance solely by modifying the chemical structure of polymers or incorporating fillers such as glass fiber and carbon fiber can no longer fully meet these demands. Taking poly(phthalazinone ether sulfone ketone) (PPESK) as an example

this study modifies a conventional extruder head by incorporating an annular expansion strengthening device

analogous to the principle of film blowing

to enhance pipe strength. The annular expansion effect of the designed extruder head is simulated and analyzed using Ansys-Polyflow. At an expansion angle of 30°

a suitable annular expansion velocity component of 3.51 cm/s is obtained

under which the melt maintains favorable flow characteristics without significant vortex or stagnation. The velocity component in the annular expansion direction causes the molecular chains within the melt to deviate from their original flow direction and form an orientation along the axial direction

thereby improving the circumferential stress resistance of the pipe.
