| 摘 要： | 采用等通道转角挤出（ECAE）方法对高密度聚乙烯（HDPE）进行自增强挤出，研究挤出工艺条件与材料结构、性能之间的关系．利用广角X射线衍射（WAXD）、差示扫描量热分析（DSC）等手段对材料结构进行表征，结果表明：经过等通道转角挤出后，HDPE的结晶度提高、晶粒细化，抗拉强度提高了23％．

| Abstract: | In the paper,it was studied thatthe relationship between processing conditions,structures and the properties of high-density polyethylene(HDPE)treated by the new processing method of equal channel angular extrusion(ECAE).Wide-angular X ray diffraction(WAXD)and differential scanning calorimetry(DSC) were used to investigatethe structure changing.Significant changesof crystalline are taken place.The crystalline degree is increased and crystalline grain is decreased.Thetensile strength ofhigh-density polyethylene is increased up to 23%. |
