[0004] Polycarbonate plastics are mostly disposable. Millions of tons of white garbage are scattered in nature after being discarded. They can neither rot and transform nor degrade and disappear by themselves. The waste of precious non-renewable resources, how to effectively recycle waste polycarbonate plastics has attracted the attention of researchers from all over the world.

The invention discloses a cleaning method of plastic particle raw materials. The cleaning method comprises the following steps: PC raw materials are dipped through alkali liquid in a first alkali pot; the PC raw materials are dipped in acid liquid in an acid pot; the PC raw materials, dipped in the acid liquid, are dipped through alkali liquid in a second alkali pot; the PC raw materials, treated through the alkali liquid in the second alkali pot, are purified in a first salt water pool; and the PC raw materials, purified through first salt water, are purified in a second salt water pool. The cleaning method can recover and clean a lot of waste plastics, is ordered in connection of all parts, saves both time and labor, and is high in working efficiency, low in equipment cost and simple in preparation method; and materials obtained by a waste plastic recovery device can be directly used for granulation production.
Description
technical field [0001] The invention relates to a recovery treatment method, more precisely a method for cleaning plastic granule raw materials. Background technique [0002] Polycarbonate is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. At present, only aromatic polycarbonate has been industrialized. Due to the special structure of polycarbonate, it has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. [0003] Polycarbonate plastics are widely used in clothing industry, building materials, agriculture, machinery industry, etc. Recycled granules are a kind of plastic granules, which can be used to make various plastic bag...
