摘要
利用ANSYS软件包分析了聚乙烯在“一字”型排列三螺杆挤出机常规螺纹元件中的流动情况,讨论了整个流道的速度分布、压力分布、粘度分布,并和双螺杆挤出机常规螺纹元件的挤出特性进行了比较。结果表明,三螺杆挤出机的物料输运能力、分散性混合能力以及分布性混合能力都好于双螺杆挤出机。
The flow of polyethylene in tri-screw extruder of“一”type is analyzed by ANSYS. The pressure, velocity and Viscosity distribution is discussed, and the extrusion characteristics of twin screw and tri-screw extruders are compared. The results show that tri-screw extruder has good material transportation, dispersive mixed ability and distributive mixed ability, comparing with those of twin screw extruder.
