| 摘 要： | 从理论上分析了衣架式挤出模的两个流动模型,即熔体在扇形区内等压线平行于模唇(PIPDO)模型和任一流动路径上熔体的压力损失均相等(PLFPE)模型,并证明了这两个流动模型的等效关系。考虑到"蛤壳现象"对挤出模流动均匀性的影响,提出了挤出模简化设计的容许条件。 |

| Abstract: | It analyzed two flow models of coathanger type extrusion die from the viewpoint of rheologic theory , that is, the position of the isobars parallels to the die orifice(PIPDO), and the pressure loss on all flow path is equal (PLFPE). The equivalency of these two flow models is proved theoretically. It put forward to the condition accepted for simplified design of extrusion die considering the influencing effects of "clamshell phenomenon" on the flow uniformity of die. |
