Solar EVA and Cell Encapsulation Film
Green energy is the most talked-about topic at the moment. Undoubtedly, solar energy becomes a superb one of these. Global solar technology products has developed by over than 45% each year before decade. The development and investment of solar technology of China exceeded the global 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 shall take place as the composite structure will be heating system and pressing. The cured protection 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 employment of twin screw extruder makes EVA resin and lots of additives in-line compounding possible. This significant improvement is because our profound understanding of twin screw extruder and wealthy methods. This innovation is more than technical advantages, but reducing working costs substantially.
The wonderful mixing aftereffect of twin screw extruder is playing a respected role in EVA film production, because it involves a lot of additives, and it needs good compounding. Unique screw elements and screw profile are designed according to the physical and chemical nature of EVA resin. It keeps each component blending while avoiding pre-crosslinking homogeneously. It is a basis of high productivity as well.
Special cooling channel of calenders keeps the temperature of calendar surface homogeneous. 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 continuous quantity and stable pressure. The close-loop will keep the system stable running intelligently.
Higher Efficiency, Lower Shrinkage
That is one of the givens which guarantee the low shrinkage and high light transmittance.
Full automated in-line thickness tester log and survey the thickness with time. The full automated constant tension winding system is designed refer to the mechanised nature of EVA film. Less margin waste materials, Higher rate of completed products stem from continuous optimizing of each device during long-term practice of production. These optimizations substantially help reducing operating cost.
Intelligent Control System
From relay to industry computer, we've more options available. The logic setting between each useful modules makes exact 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 final 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 assurance the shrinkage less than 3%, and the collection velocity reach at 5m/min.
