What is the production process of solar eva film?

Guangzhou Zanchen New Material Technology Co., Ltd.

1, Raw material preparation: Firstly, prepare EVA resin, cross-linking agent, silane coupling agent and other necessary modifiers. These materials will be mixed according to a specific ratio to ensure that the film has the required properties.

2, Melt extrusion: The well-mixed raw materials are extruded through the extruder head in the molten state to form the film of the required thickness.

3, Cooling and shaping: The extruded molten film is cooled by cooling rollers to fix its shape and size.

4、Cutting and Packaging: The cooled film is cut according to the specified width and length, and then packaged for subsequent encapsulation of photovoltaic modules.

5, Quality inspection: throughout the production process, there will be strict quality control measures to ensure that each batch of adhesive film meets the standards.

In addition, in order to improve production efficiency and product quality, the production process will also use continuous extrusion technology and precision coating technology and other advanced production processes.

At the same time, it also focuses on the treatment and recycling of waste materials and wastewater, in order to reduce energy consumption and resource consumption, and realise green production.

In summary, the production of solar eva film is a delicate and environmentally friendly process, which ensures the long-term stability and reliability of PV modules.

what are the main components of solar eva film?

1, EVA resin: this is the base material of solar eva film, with good transparency and adhesion.

2, Cross-linking agent: used to improve the mechanical strength and aging resistance of the film.

3, Silane coupling agent: to enhance the adhesion between the film and the glass and backsheet.

4, Other modifiers: added as needed to improve specific properties, such as UV resistance, weather resistance, etc..

In addition, apart from the above components, there are a number of other auxiliary components, the specific proportion and type of these components depend on the intended application and performance requirements of the adhesive film. During the production process, these raw materials are stirred in a mixer and left to stand for a certain period of time, and then placed in an adhesive film production line to be cast and extruded into a molten film.

Taken together, the components of solar eva film are complex and specialised, and they work together to ensure the performance and longevity of the PV module.

how does solar eva filM improve the power generation efficiency of the cell?

1, High transmittance: solar eva film has high transparency, can maximise the sunlight through the film to reach the battery cell, so that more light energy is absorbed by the battery cell, thus improving the photoelectric conversion efficiency.

2, UV and weather resistance: sealing film needs to have good UV and weather resistance to prevent yellowing or degradation of performance due to prolonged exposure to the outdoors, these characteristics help to maintain long-term power generation efficiency.

3, Good adhesion: sealing film and photovoltaic glass and backsheet good adhesion to ensure the structural stability of the module, reducing the delamination or water vapour infiltration caused by battery corrosion, these factors have a direct impact on the power generation efficiency and service life of the photovoltaic module.

In summary, solar eva film plays a crucial role in the protection and power generation efficiency of PV modules through its physical and chemical properties. Although it accounts for a small percentage of the cost of a PV module, it has a significant impact on the performance and lifetime of the module.
