摘要

塑料制品作为一种全球范围内广泛使用的商品

几乎已经渗透到了人类生活中的各个方面。同时

快速累积的废旧塑料对陆地和海洋环境产生了一系列的负面影响。值得注意的是

废旧塑料具有资源和废物双重属性。废旧塑料的回收品质和数量的提高

对于资源的高效利用、可持续发展和环境保护具有重大意义。本文介绍了废旧塑料常用的分选方法

综述了近年来国内外废旧塑料化学改性和物理改性的研究进展

并分析了废旧塑料改性再生所面临的问题。

Abstract

Plastic products have become the major commodities on a global scale and have infiltrated almost every aspect of human life. Meanwhile

the rapidly accumulated waste plastics have caused a series of negative impacts on the terrestrial and ocean environment. Noticeably

waste plastic has the dual characteristics of resources and waste. The improvement of recycling quality and quantity of waste plastics is of great significance to the efficient utilization of resources

sustainable development and environmental protection. Besides

the Herein

the sorting methods commonly used for waste plastics were introduced

the research progress of chemical (such as chain extension

grafting and crosslinking reaction) and physical modification (such as of waste plastics were reviewed

and the problems of the reuse of waste plastics were also analyzed.
