Short Description:
With the development of the global green energy, the photovoltaic economy is gradually highlighted. In order to meet the market demand, LEADER newly developed the EVA POE EPE (EVA+POE+EVA) solar film photovoltaic film solar cell encapsulation film extrusion lines, warmly welcomed by domestic and foreign customers. The market growth of EVA POE solar film extrusion lines is mainly affected by the growth of photovoltaic installed capacity in China and the world. With the continuous decline of photovoltaic energy cost, photovoltaic power generation will accelerate to replace other traditional fossil energy power generation methods under the background of carbon neutralization.
MAIN FEATURES AND ADVANTAGES OF THE EXTRUSION LINE
1) The extrusion line can produce both EVA films, POE films and also EVA+POE+EVA 3 layers co-extrusion films.
2) High capacity and speed: if produce EVA film, line speed can be up to 15-18m/min. If POE film, line speed can be 10-13m/min. If EPE film, speed can be 12-15m/min normally.
3) Five roller calendars calendaring tech can guarantee the film calibrating very well.
4) Adopt automatic T die and online thickness scanner to form a closed loop PID control.
5) Adopt tension-free or micro-tension edges cutting and slitting.
6) Cooling parts can ensure shrinkage rate less than 3%.
