机械挤出法在废橡胶还原再生中的研究进展

Research Progress of Mechanical Extrusion in Waste Rubber Reclaiming

介绍废橡胶脱硫工艺的发展和废橡胶物理还原再生方法,梳理机械挤出法在废橡胶还原再生中的应用,包括螺杆机械挤出法(单螺杆机械挤出法和双螺杆机械挤出法)、无螺杆(拉伸流变)机械挤出法、磨盘机械挤出法(立式磨盘机械挤出法和卧式磨盘机械挤出法)和组合机械挤出法,指出机械挤出法是废橡胶综合利用行业的发展方向。

The development of waste rubber desulfurization process was presented,the physical reduction and regeneration method of waste rubber were analyzed,and the application of mechanical extrusion method in the waste rubber reclaiming was discussed.The mechanical extrusion method included screw extrusion using either single screw or twin screw extruder,screwless extrusion using extensional rheology system,grinding disc method using vertical disc or horizontal disc,and combination of the above mentioned methods.Mechanical extrusion reclaiming was the future direction of waste rubber utilization.
