Solar Cell and EVA Encapsulation Film

Green energy is the most talked-about topic at the moment. Undoubtedly, solar energy becomes a superb one of them. Global solar energy products has developed by over than 45% annually in the past decade. The development and investment of solar technology of China exceeded the world average.

Solar module is laminated by steel glass--EVA film--semiconductor wafer--EVA film- backsheet as it shown in figure "Schematic of Solar Cell Encapsulation". Cross-linking and curing will need place as the composite framework will be heating system and pressing. The cured safety layers can prevent solar modules from harsh environment damage while keeping high light transmittance.

Twin screw extrusion system

Twin screw extruder direct extrusion technology is one the most crucial characteristics of this line. The successful work of twin screw extruder makes EVA resin and lots of additives in-line compounding a reality. This meaningful improvement is a total result of our profound understanding of twin screw extruder and wealthy practices. This creativity is more than technical advantages, but reducing operating costs substantially.

The excellent mixing effect of twin screw extruder is playing a leading role in EVA film production, because it involves a lot of additives, and it requires good compounding. Unique screw elements and screw profile are designed based on the physical and chemical nature of EVA resin. It keeps each component combining homogeneously while avoiding pre-crosslinking. It really is a basis of high productivity as well.

Special cooling channel of calenders keeps the temperature of calendar surface consistent. Peculiar silicon coated calendar can remove the stress of EVA film effectively so that lower the shrinkage rate significantly.

German-made gear pump ensures melt getting into T-die with constant quantity and stable pressure. The close-loop will keep the system stable operating intelligently.

Higher Efficiency, Lower Shrinkage

This is one of the givens which guarantee the low shrinkage and high light transmittance.

Full automated in-line thickness tester log and record the thickness in time. The full automated constant stress winding system is designed make reference to the mechanical nature of EVA film. Less margin waste, Higher rate of completed products stem from constant optimizing of each device during long-term practice of creation. These optimizations substantially help reducing operating cost.

Intelligent Control System

From relay to industry computer, we have more options available. The logic establishing between each practical modules makes exact control simple. Safer production is a complete consequence of considered mechanised and electrical security. The complete sync and synergetic control of each unit guaranteed the high quality last product relaxed.

Excellent Quality of EVA Film

The pursuit of each detail leads to a world class EVA solar cell encapsulation film. We can promise the shrinkage less than 3%, and the collection speed reach at 5m/min.
