<p><P>PROBLEM TO BE SOLVED: To solve the following problem in a demolition method of a conventional display panel device: in a decomposition process, a display panel is broken due to differences in thermal expansion coefficient of the display panel and heat sinks, which results in a low-yield recycle process. <P>SOLUTION: The demolition method of a display panel device, provided with a display panel, a metal plate with a plurality of slits, a face having a plurality of slits of the metal plate stuck to the display panel with a first adhesive layer, and an adhesive sheet stuck with a second adhesive layer, comprises: a step of injecting a separating medium consisting of thermal expansion particles and a remover in the slits of the heat sinks; a step of impregnating peeling liquid contained in the remover into the second adhesive layer, and preheating for volatilize a solvent contained in the remover; and a step of properly heating for expansion of the thermal expansion particles. Accordingly, the plasma display panel and the heat sinks can be easily separated, resulting in efficient recycling. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
