摘要
综述了近年来食品用塑料制品中掺杂回收塑料鉴别技术的研究现状和最新进展,涉及到的塑料主要包括聚乙烯(PE)、聚丙烯(PP)、聚酯(PET)、聚苯乙烯(PS)和聚氯乙烯(PVC),并重点讨论了红外光谱法、热分析法、分子量及其分布分析法、力学性能分析法等鉴别技术在该领域的应用状况。同时对国内在该领域的发展趋势进行了分析和展望。
The current research progress and latest advances in identification techniques of food-related plastic products doped with recycled plastics were reviewed, which include PE, PP, PET, PS and PVC; and the application of several identification techniques such as FT-IR, thermal analysis, analysis of molecular weight and its distribution and analysis of mechanical properties in this field were discussed. Meanwhile, the prospective development in China was also anticipated and analyzed.
