Abstract

The effect of high shear rate on the mechanical properties of polyethylene (PE), poly(ethylene terephthalate) (PET), polystyrene (PS) and polypropylene (PP) waste blend was investigated. The process was carried out at a temperature of 120°C using a counter-rotating twin-screw extruder. A constant screw speed of 250 rpm and a constant weight ratio of the PE/ PET/PS/PP components of 1:1:1:1 were used. The preliminary research showed that the high shear rate had no effect on the impact strength. However, the significant improvement in the flexural properties was observed as compared to those obtained at a lower screw speed of 80--120 rpm.

高剪切速率对聚乙烯、聚对苯二甲酸乙二醇酯、聚苯乙烯和聚丙烯废料共混物力学性能的影响

研究了高剪切速率对聚乙烯(PE)、聚对苯二甲酸乙酯(PET)、聚苯乙烯(PS)和聚丙烯(PP)废旧共混料力学性能的影响。该工艺在120°C的温度下使用反向旋转双螺杆挤出机进行。螺杆恒转速为250 rpm, PE/ PET/PS/PP组分的重量比为1:1:1:1。初步研究表明，高剪切速率对冲击强度没有影响。然而，与较低螺杆转速(80- 120 rpm)相比，观察到弯曲性能的显著改善。
