Solar EVA and Cell Encapsulation Film

Green energy is the most talked-about topic at present. Undoubtedly, solar technology becomes an outstanding one of them. Global solar technology products is rolling out by over than 45% yearly before decade. The development and investment of solar energy 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 while the composite framework will be heating system and pressing. The cured security layers can prevent solar modules from severe 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 employment of twin screw extruder makes EVA resin and a true number of additives in-line compounding a reality. This meaningful improvement is because our deep knowledge of twin screw extruder and wealthy procedures. This innovation is more than specialized advantages, but reducing operating costs substantially.

The wonderful mixing aftereffect of twin screw extruder is playing a leading role in EVA film production, because it involves a great number 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 mixing while avoiding pre-crosslinking homogeneously. It really is a basis of high productivity as well.

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

German-made equipment pump ensures melt entering into T-die with continuous quantity and stable pressure. The close-loop will keep the operational system stable running intelligently.

Higher Efficiency, Lower Shrinkage

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

Full automatic in-line thickness tester log and statement the thickness with time. The full automatic constant pressure winding system is designed refer to the mechanical character of EVA film. Less margin waste materials, Higher rate of finished products stem from constant optimizing of every device during long-term practice of production. These optimizations help reducing operating cost significantly.

Intelligent Control System

From relay to industry computer, we have more options available. The logic setting between each useful modules makes precise control simple. Safer creation is a complete result of considered mechanical and electric protection. The complete sync and synergetic control of each unit guaranteed the high quality last product at ease.

Excellent Quality of EVA Film

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