用自行设计的分离器,以浮沉法分离了回收塑料瓶盖中的高密度聚乙烯(HDPE)和聚丙烯(PP)。研究了混合塑料中HDPE和PP的含量、回收塑料尺寸以及分离液密度等因素对分离效果的影响。结果表明:分离后得到的产物中HDPE和PP的纯度可达到97%以上。
Using a self-designed separator, high density polyethylene (HDPE) and polypropylene (PP) in the recycled plastic closures were separated by floatation. The effects of HDPE and PP content in mixed plastics, the size of recycled plastic and the density of separating liquid on the separation efficiency were studied. The results show that the purity of HDPE and PP in the product obtained after separation can reach more than 97%.
