| 摘 要： | 利用差示扫描量热法(DSC)对水辅助注塑尼龙6(PA6)制品靠近注水喷嘴(P1)位置和远离注水喷嘴(P2)位置的表层、中芯层和水道层的结晶行为进行了研究,并初步探讨了高压水对PA6制品结晶行为的影响。结果表明:对于P1和P2位置,表层与水道层的结晶度均低于中芯层的结晶度;P1位置表层与水道层结晶度均低于P2位置同层的结晶度;P1位置中芯层结晶度高于P2位置中芯层的结晶度;高压水的冷却作用会降低水道层熔体的结晶度并促使水道层形成较小的晶体。 |

| Abstract: | The crystallization at the near gate end(position P1) and far gate end(position P2) of nylon 6(PA6) part moulded by water-assisted injection moulding(WAIM) was characterized by DSC.The effect of high pressure water on the crystallization behavior of WAIM part was also discussed.The results show that the crystallinity of the skin layer and water channel layer at both positions is lower than that of the core layer;the crystallinity of the skin layer and water channel layer at position P1 is lower than that of... |
