【摘要】 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。更多还原

【Abstract】 The HDPE and PP recycled from plastic lids were separated with sink-float separation method by use of self-designed separator.The effects of content of HDPE and PP in mixture,the size of recycled plastic and separation liquid density on the separation effect were studied.The results show that: the purity of HDPE and PP is up to 97% after been separated.更多还原
