摘要
针对废旧塑料在回收利用过程中存在的分类识别与回收两大关键技术难题,综述了废旧塑料识别分选方法与回收技术,重点介绍了光谱鉴别法在废旧塑料鉴别上的应用,近红外光谱(NIR)技术和激光诱导击穿光谱(LIBS)技术将成为未来废旧塑料鉴别回收的重点发展方向。
In view of the two key technical problems in the process of waste plastics recycling,the identification and separation methods and recycling technology of waste plastics were summarized,and the application of spectral identification in the identification of waste plastics was emphatically introduced.Near infrared spectroscopy(NIR)and laser-induced breakdown spectroscopy(LIBS)would become the key development direction of identification and recovery of waste plastics in the future.
