近年来,聚合物材料的回收利用受到关注。对于热塑性材料,只要将材料加热和熔融就可以实现回收利用;对于热固型材料如橡胶,可供选择的回收利用方法就受到较大限制。但从经济和环境方面考虑,橡胶应该被回收利用。对通用单螺杆挤出方法作为连续橡胶回收工艺使天然橡胶屑粒返原进行了研究。研究发现,挤出机温度所起的作用似乎比螺杆速度重要得多。 In recent years, the recycling of polymer materials has drawn attention. For thermoplastics, they can be reused as long as they are heated and melted, and for thermoset materials such as rubbers, alternative methods of recycling are more limited. However, from the economic and environmental considerations, rubber should be recycled. The common single-screw extrusion method as a continuous rubber recovery process of natural rubber crumbs back to the original were studied. The study found that extruder temperature seems to play a much more important role than screw speed.
