Patent number: 5851065Abstract: A process and an apparatus for recycling resin scrap including a thermosetting resin paint film and a thermoplastic resin substrate as its major components, wherein the resin scrap is supplied into a passage of a cylinder, melted, and delivered by screw arrays from an upstream side to a downstream side of the passage of the cylinder, and hydrolyzed by a hydrolyzing agent while forming a highly packed region with a resistor. The resistor restricts the resin scrap to flow from the upstream side to the downstream side in a short period of time, and forms the highly packed region where a contact efficiency is enhanced between the resin scrap and the hydrolyzing agent.Type: GrantFiled: April 16, 1996Date of Patent: December 22, 1998Assignees: Toyota Jidosha Kabushiki Kaisha, The Japan Steel Works, Ltd., Kabushiki Kaisha Toyota Chuo KenkyushoInventors: Sadao Ikeda, Makoto Kito, Yoshio Taguchi, Atsushi Tanaka, Shigeki Inoue, Naoyuki Murata, Shinichi Ninomiya, Yoshitaka Kimura
