Title:
熱可塑性樹脂成形品廃材の再資源化方法
Document Type and Number:
Japanese Patent JP5056056
Kind Code:
B2
Abstract:
A method for recycling comprises a pulverization step (S1) of pulverizing thermoplastic resin molded articles, each having a different softening point in a resin substrate and having a metal part and a coating film, a metal-material selection-removal step ( S3 ) of selecting and removing a metal material from pulverized pieces, a pulverized resin-material selection step ( S5 ) of selecting a target pulverized resin material for recycling by allowing the pulverized pieces from which the pulverized metal material has been removed to drop and by ejecting gas toward either one of the target pulverized resin material and a non-target pulverized resin material for changing a drop direction thereof, and a coating-film peeling step ( S7 ) of peeling the coating film from the resin substrate by applying a shearing force to the target pulverized resin material under the softening point of the resin substrate of the target pulverized resin material for recycling.
