METHOD FOR PYROLYZING PLASTIC

摘要

PURPOSE:To remove a plastic coated on a metallic body by preventing the metallic body from being deformed and heating the metallic body. CONSTITUTION:Materials 13 coated with a plastic such as a vehicular steering wheel in which a metallic body is coated with a plastic through a polyurethane or an adhesive containing the polyurethane are housed in a pyrolytic furnace 1 and irradiated with microwaves from a microwave oscillator 3, and heated. Thereby, the plastic and adhesive are pyrolyzed and removed. This method can be carried out in an apparatus and the use of an organic solvent is not required. The throughput is simultaneously increased to facilitate the operating procedures.
