METHOD FOR RECOVERING POLYCARBONATE RESIN FROM DISCARDED OPTICAL DISC AND/OR RECOVERED OPTICAL DISC, FLAME-RETARDANT POLYCARBONATE RESIN COMPOSITION, INJECTION MOLDED BODY, AND MOLDED ARTICLE FOR OPTICAL USE |
摘要 |
<p>Provided is a method for recovering a polycarbonate resin from a discarded optical disk and/or a recovered optical disk, which has a polycarbonate resin substrate. The following process steps (I) and (II) are applied to a chemically treated product, which is obtained by crushing a discarded optical disk and/or a recovered optical disk, and chemically treating the resulting crushed product. Process step (I) : a step containing (a) removing a magnetic metal foreign matter with a magnet, and (b) identifying a colored foreign matter with an optical camera, and removing the colored foreign matter. Process step (II): a step containing detecting the presence of a metal foreign matter with a metal foreign matter detector, and removing a resin containing the metal foreign matter.</p> |
