METHOD OF SEPARATING MIXED PLASTIC |
摘要 |
<p>A problem of the invention is to provide a method which targets on polyethylene terephthalate-made bottle scraps composed mainly of polyethylene and/or polypropylene, polystyrene and a polyester and which is able to treat continuously a large amount of the polyester component with a high purity and sort and recover it in a high recovery. The problem of the invention can be solved by a separation method of waste plastics, which is characterized by forming previously a crushed plastic into a water slurry, feeding the water slurry in a fixed rate range such that a swirling flow is generated within a cylindrical tank and that water rises in a fixed rate range and recovering a polyester with a high specific gravity as a precipitated component within the cylindrical tank and a plastic with a low specific gravity as an overflow component from the top of the cylindrical tank, respectively.</p> |
