Production description: high precision feeding and high quality

EVA/POE Solar film extrusion line

Automatic gravimetric feeding system ensures high precision feeding of various solid and liquid additives and raw materials.Low- temperature extrusion system is plasticized under the premise of sufficient stirring to prevent additives from crosslinking. Special design of Casting part give the perfect solution to roller sticking, stripping.Special online tempering device to get rid of inner stress. Tension control system ensure the flexible sheets conveying placidly during cooling , pulling and winding process.The system can feedback the production quality of EVA/POE solar film in real time.

Four advantages of  EVA/POE Solar Film

1. Ultra-high light transmittance with excellent photoelectric conversion efficiency

The light transmittance is over 92%, which maximizes the penetration of sunlight through the film to photovoltaic cells, effectively improving the photoelectric conversion efficiency of modules and ensuring the power generation revenue of photovoltaic power stations.

2. Excellent adhesive sealing performance and weather resistance

It features strong adhesion to photovoltaic glass, backsheets and solar cells, with no air bubbles or delamination after forming. It is resistant to high and low temperatures (-40℃~150℃), ultraviolet rays, wind and rain aging, and has an outdoor service life of more than 25 years, meeting the long-term application requirements of photovoltaic modules.

3. Outstanding aging resistance and PID resistance

The photovoltaic film based on POE has excellent volume resistivity and damp-heat resistance, which can effectively inhibit the Potential Induced Degradation (PID) of photovoltaic modules. Modified EVA film can also achieve high PID resistance, greatly reducing the power attenuation rate of modules.

4. Superior flexibility and chemical corrosion resistance

The film has good toughness, is not easy to crack or damage during processing and forming, and is suitable for the lamination process of photovoltaic modules. Meanwhile, it is resistant to acid, alkali and water vapor erosion, adaptable to the complex outdoor working conditions of photovoltaic power stations, and avoids internal corrosion failure of modules.

Technical advantages of Jwell EVA/POE Solar Film Extrusion Line 

1. Intelligent Feeding & Formulation Control System

Automatic weighing metering device: The precision reaches ±0.1%, which can accurately proportion multiple components such as EVA/POE raw materials, cross-linking agents and tackifiers simultaneously.

2. Low-temperature Extrusion & Anti-crosslinking Technology (Core Innovation)

Customized screw design: Single screw is applied for EVA, and large-diameter single screw or twin screw is adopted for POE, tailored to the material characteristics.

3. Casting Forming & Surface Treatment Technology

Special T-die: Extended die lip design improves the orientation consistency of finished products, reduces die swell, and increases the adjustment response sensitivity by 50%.
