【Abstract】 Identification and sorting of waste plastics is a very necessary part for a plastics recycling system. Among a number of the techniques for identification of plastics, the nearinfrared method is of advanced and interesting nature. This paper,apart from describing the principles,advantages and limitations,summarizes the technological flow chart,operational parameters and characteristics of several plastics identification systems which have been industrialized abroad (mainly in Europe).更多还原
