The method for being usually used in removing solar cell backboard at present mainly has direct removing method, alcohol wipe method and heating
Removing method.It is very time-consuming using method is directly torn off, and it is bonded again after reprocessing, it is inadequate with EVA peel strength, therefore also gradually not
It uses again.It is fast and high-efficient that alcohol wipe method has the advantages that speed, however is bonded again after reprocessing, still with EVA peel strength
So it is less than 10N/cm, it is unsatisfactory.Heating removing method is the common repair method of current most module factories, is bonded again after reprocessing,
It can achieve 40N/cm or more with the peel strength of EVA, be comparatively ideal scheme.
In general, heating removing method is (120 DEG C × 10 points) backboard or glass to be heated with heating table top, or use heat
Air pressure gun (300~400 DEG C) blow-through backboard or glass remove solar cell backboard after EVA softening again.In actual treatment, often
Often discovery is because fitting is too close, after removing solar cell backboard, in there are the residual of solar cell backboard on EVA
Glue, or even too big because sticking together power, causes greatly to damage at the problems such as causing area battery piece to rupture during removing
