SOLUTION FOR SEPARATION OF INTERLAYER FILM AND INTERLAYER FILM SEPARATION METHOD

摘要

Disclosed are a solution for use in the separation of an interlayer film and a method for separation of an interlayer film, which can separate an interlayer film from a glass pane within a short time and can collect the separated interlayer film in a recyclable form. A solution (21) for separation of an interlayer film has an etching effect against glass. The solution (21) is charged into a vessel (22), and the temperature of the solution (21) is adjusted to 30 to 60ºC. A laminated glass pane (10) whose glass panes (11, 12) are fractured is charged into a barrel (23) through a lid (23a), and 50 to 60 metal pieces (25) are also charged into the barrel (23) through the lid (23a) so that the laminated glass pane can be separated into the glass panes (11, 12) and the interlayer film (23) readily. The barrel (23) containing the laminated glass pane (10) and the metal pieces (25) is rotated at a predetermined rotational speed.
