循环再利用聚酯的再生工艺、行业应用与鉴别特征
Recycling processes,industrial applications,and identification characteristics of recycled polyester
摘要
Abstract
This paper reviewed recycling methods for polyethylene terephthalate(PET)waste,covering both physical and chemical regeneration processes.The applications of recycled PET(rPET)in sectors such as textiles and food pack-aging were summarized,emphasizing its versatility across industries and significant market potential.The review also de-lineated structural and performance differences between PET and rPET,and elaborates on identification methods that le-verage these distinctions through advanced chemometric techniques and machine learning models,as investigated in do-mestic and international research.Finally,future studies should prioritize cost reduction in chemical regeneration process-es,development of higher-value-added rPET products,and the establishment of rapid,reliable identification protocols to enhance quality control and sustainability efforts.关键词
