Features of EVA POE Photovoltaic Solar Film Extrusion Line
China Jwell eva film extrusion line adopts single screw extrusion for EVA and single screw extrusion for POE. The screw and barrel constant temperature circulating water cooling system solves the technical problems of EVA/POE plasticization and non-crosslinking.
The roller body adopts double-sided embossing, which solves the technical difficulty of film sticking to the roller.
The cooling part adopts cooling roller and stress-relieving cooling bed, so that the film runs smoothly, the molding is sufficient, and the shrinkage rate is guaranteed to be less than 3%.
The whole line of EVA film extrusion line adopts PLC automatic control to realize man-machine interface operation.
As an EVA film extrusion line manufacturer, Jwell is equipped with an online quality monitoring system to ensure product qualification rate.
Patented design micro tension winder, the line speed of the whole machine can reach 18m/min.
Application of EVA POE Photovoltaic Solar Film Extrusion Line
EVA film is a thin film product which is made of EVA as the main raw material, added with various modifying additives, fully mixed, heated by the production and processing equipment, cast and extruded. The cured EVA can withstand atmospheric changes and has elasticity. After bonding with the glass, it can improve the transmittance of the glass, play a role in enhancing the transmittance and gain the output of the solar cell module. Therefore, it is an ideal packaging material for solar cell modules and glass.
