<p><P>PROBLEM TO BE SOLVED: To provide a method for efficiently separating laminated glass into an interlayer and glass constituting the laminated glass, e.g. for recovering the glass part of the laminated glass and to provide a separation apparatus for applying the method. <P>SOLUTION: The method for separating laminated glass composed of glass plates 2 and 3 and an interlayer 1 in between into glass pieces 11 and the interlayer 1 comprises the followings: a first step for crushing a laminated glass 4 into cullet-like glass pieces 10; a second step for lowering the adhesive force of the interlayer 1 still adhering to the cullet-like glass pieces 10; a third step wherein the laminated glass 4 is inserted between two screens facing each other, i.e. a lower-glass-plate separation screen 21 capable of vibrating almost horizontally and an upper-glass-plate separation screen 22 freely oscillating almost horizontally, so that the glass plates 2 and 3 are in contact with the screens 21 and 22, respectively; and a fourth step wherein the lower-glass-plate separation screen 21 is vibrated, thus subjecting the interlayer 1 with the cullet-like glass pieces 10 adhering thereto and the upper-glass-plate separation screen 22 to self-excited vibration. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
