The production line can be customized according to customer requirements. The film product is a new type of thermosetting hot-melt film, which is not sticky at room temperature and is easy to operate.
Solar panel packaging film extrusion line uses EVA or POE as raw material. The converting process includes material handling, heating, extrusion, calendering, cooling, and winding. The production line can be specially made according to customer requirements. The film product is a new type of thermosetting hot-melt film, which is not sticky at room temperature and is easy to operate. After heating and lamination, it is fully set and bonded. It can firmly bond silicon wafers, glass, and backplane multi-layer materials into one. Excellent resistance to heat and humidity, anti-ultraviolet performance, fully meet the requirements of long-term use of solar modules outdoors.
The EVA film production line for photovoltaic cell packaging developed by GWELL is an energy-saving, efficient, innovative and cost-effective extrusion production line. It is currently the most professional EVA film control production equipment for photovoltaic cells in China. For EVA photovoltaic adhesive film, the thermal shrinkage rate is generally required to be below 5%, in order to meet the requirements of battery packaging.
In the traditional EVA photovoltaic film extrusion production equipment, due to the limited shrinkage requirements, the production speed is almost entirely dependent on the extrusion speed when the melt flows out of the die, which leads to the inability to increase the production speed. The newly launched low-shrinkage EVA photovoltaic film high-speed extrusion technology has made a major breakthrough in this area. Through the professionally developed stress relief device, the residual stress generated during the stretching of the film and the production process can be effectively eliminated online, so as to better solve the problem of thermal shrinkage of the EVA film.
EVA film has the advantages of environmental protection, long-term UV resistance, no yellowing, high light transmittance, strong adhesion, aging resistance, and low heat shrinkage. This product is mainly used for the packaging of solar cell modules. After lamination and curing, bonding and sealing are performed. It has the functions of high light transmittance of battery components, prevention of water vapor penetration, high and low-temperature resistance, and anti-ultraviolet rays, etc., to ensure stable and efficient use of battery components. , is a novel and reliable packaging material.
POE polyolefin elastomer has the general characteristics of thermoplastic elastomers but also has excellent toughness and good processing performance. The product features are as follows:
The encapsulation film for double-glass modules mainly includes EVA film and POE film. The photovoltaic film is mainly used in the encapsulation of photovoltaic modules and is the key material of photovoltaic modules. Adhesive film bonds photovoltaic cells with photovoltaic glass and the back sheet protect the cells and package them into photovoltaic modules capable of outputting direct current. If the film has problems such as a drop in light transmittance during use, the module will not be able to generate electricity normally and will be scrapped. Therefore, photovoltaic modules have higher requirements on light transmittance, weather resistance, bonding strength, aging resistance, and other properties of the adhesive film used for packaging.
The photovoltaic adhesive film is the core material of photovoltaic modules, including EVA adhesive film, POE adhesive film, etc. Among them, EVA is the most important packaging material. Although the cost of adhesive film only accounts for about 4% of the module cost, it is a key factor in determining the quality and life of photovoltaic module products.
