摘要: 介绍了使用聚合物动态塑化单螺杆挤出机对聚氯乙烯(PVC)/术粉复合材料进行加工时,螺杆轴向振动对其挤出片材的拉伸性能的影响。将在振动频率为5-25Hz,振幅为40~200μm下挤出的PVC/木粉复合材料的拉伸性能和稳态状况下挤出的复合材料拉伸性能进行对比,从中找出最佳的振动参数范围。结果表明,振动频率为20 Hz,振幅为120μm时,复合材料的整体拉伸性能最佳,其拉伸强度、拉伸弹性模量、断裂伸长率和稳态相比都有较大的提高。

Abstract: The paper introduced the influence of screw axial vibration on extrusion properties of poly (vinyl chloride)(PVC) /wood-flour composite, when it was processed by singlc screw dynamic extrusion.The tensile properties of PVC/wood-flour composite resulted by different screw vibration parameters (amplitude and frequency) were compared with those in static extrusion. It showed that the best vibration parameters were 20 Hz vibration frequency and 120μm amplitude.
