Uneven EVA photovoltaic lamination temperature
Problembeschreibung
Different areas of the same module have different curing degrees.
Ursachenanalyse
Uneven heating plate temperature causes local premature curing or insufficient curing; temperature differences between the four corners and the center of the module are common.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Lösung
①Pad high-temperature cloth to make the module heated evenly (large temperature difference less than 4°C); ②overhaul the heating plate temperature distribution; ③optimize the lamination curve; ④regularly test the heating plate.
Wichtigste Erkenntnis
Lamination temperature uniformity directly affects module consistency; high-temperature cloth is a simple and effective temperature equalization means.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
