| 中文摘要 |
| 日常用的饮料瓶是聚酯(PET)和高密度聚乙烯(HDPE)为原料而制成的,因而聚酯(PET)废塑料瓶是数量较多和回收价值高的一种塑料。本研究首先对聚酯(PET)废塑料瓶进行破碎,然后采用气流分选,清洗净化和水浮选组合工艺进行PET和HDPE及塑纸的分离回收。PET和HDPE的回收率分别为97%和95%,同时通过清洗净化可使回收的PET纯度达96%以上,该PET是一种用途广的优良塑料原料。 |
| 英文摘要 |
| The recycles of PET and high density polyethylene (HDPE)from the used plastic drinking bottles made of them were carried out by using a process eomprising steps of:smashing the used bottles into pieces,air seperation,cleaning,and floating.With this process, PET, HDPE and other plastic wastes were effectively seperated and recovered at a rate of 97% for PET and a rate of 95% for HDPE.The recovered PET had a purity of above 95% and could be recycled as a raw material of plastics having a high quality. |
