SEPARATING METHOD FOR LAMINATED GLASS CONSTITUTING MEMBER

摘要

PROBLEM TO BE SOLVED: To separate a laminated glass constituting member by heat treating a laminated glass formed of at least one inorganic glass plate and one plastic layer bonded with the glass under gas atmosphere. SOLUTION: For the purpose of recovering at least a part of a laminated glass nondestructively, the laminated glass is heated to 300 deg.C final temperature at the maximum heating rate 50 deg.C/minute in the heating stage. Then, in the holding stage, the laminated glass is held at the final temperature until a plastic layer is thermally decomposed and/or evaporated.
