DISINTEGRATION METHOD OF RESIN MOLDED PART

摘要

PROBLEM TO BE SOLVED: To provide a method capable of disintegrating a resin part of a resin molded part and easily separating the resin part from a metallic part. SOLUTION: The part molded from a resin is disintegrated after being pretreated with a water absorbing process for absorbing water into the part by subjecting the part to the external pressure of 0.1 MPa and heating at a temp. equal to or above the glass transition point of the resin and with an environmental changing process for changing at least either of the external pressure and the temp. of the part in the water absorbing process in this order.
