the irradiation assembly irradiates the double-glass laminated piece to enable the packaging adhesive film in the double-glass laminated piece to lose viscosity;
separating the two glass layers and the packaging adhesive film layer in the double-glass laminated piece;
and stripping and recycling the crystalline silicon remained on the packaging adhesive film layer.
5. The dual glass laminate recycling method according to claim 4, wherein separating the two glass layers and the encapsulating film layer in the dual glass laminate comprises the steps of:
separating the tack-free encapsulating film from one of the two glass layers in the dual glass laminate;
cleaning the crystalline silicon remained on the packaging adhesive film and collecting the crystalline silicon for recycling;
The tack free encapsulating film is peeled from the other of the two glass layers in the dual glass laminate and stored in a roll.
