<p>PURPOSE:To simplify a manufacturing process for releasing a vinyl chloride resin and a metal and to reuse both of them as raw materials by applying processing to the vinyl chloride resin and the metal to classify both of them. CONSTITUTION:A molding material formed by bonding a vinyl chloride resin 3 and a metal 1 by an adhesive 2 is immersed in a penetrating liquid 5. Thereafter, the molding material is taken out of the penetrating liquid to be classified into the vinyl chloride resin 3 and the metal 1. Herein, as the penetrating liquid, for example, trichloroethylene, trichloroethane, perchloroethylene and a penetrating liquid dissolving an adhesive are used.</p> |
