SOLAR EVA FILM

(High Transmission+UV Resistance Encapsulation)

Laminating Steps

Laminating: laminate the glass, EVA film, connected silicon cells, EVA film, TPT backsheet foil in sequence.

Vacuum pumping: Place above laminated pieces into the lower room of the double-vacuum press.  Then the upper room and the lower room are vacuumed synchronously about 6min.

Heating: the upper room and the lower room are kept vacuum, meanwhile heat the laminated pieces.

Press: Laminated pieces are heated under 135°C-140°C conditions, the upper room cancel vacuum and get back to atmospheric pressure.  At that time the lower room is still kept vacuum, that is to say, the upper room press on the laminated pieces of the lower room.

Curing: Isothermal curing under the curing temperature.

Cooling and framing: After isothermal curing, cancel the vacuum of the lower room, open the top of the press, and take out the laminated modules.  Then cut off the extra EVA of composite lamination edge.  Moreover seal frame and equip the termainal box, assemble PV modules at last.
