Description
PP solar photovoltaic backsheet production line components
- Extrusion part: ultra-high torque reducer with Siemens motor, special mixing, and high plasticizing screw.
- Mold part: Fully automatic sheet mold can be adjusted quickly, efficiently, and conveniently without stopping the machine.
- Three-roll part: Japan Yaskawa servo control alloy steel thin-walled roll group cooling efficiency is greatly improved.
- Rewinding part: the patented micro-tension rewinding end face is neatly and automatically cut off.
Production line introduction
- PP solar photovoltaic backsheet production line: The thin film is used for solar backsheet film to protect the battery sheet, mainly for anti-aging and wear-resistant functions.
- PVDF outdoor decorative film production line: the film is used for the protection of glass, exterior walls, doors, windows, outdoor billboards, etc. of outdoor buildings, mainly for aging resistance and wears resistance.
- PP battery diaphragm production line: the film is used for diaphragm applications in fuel cells and lithium-ion polymer batteries.
- PVDF membrane filtration production line: Membrane filtration membranes are used for water purification and are divided into ultrafiltration membranes and microfiltration membranes. They are mainly used for sewage treatment, seawater desalination, and removal of impurities such as macromolecules, bacteria, sediment, and salt.
- PVDF piezoelectric film production line: PVDF piezoelectric film has the advantages of wide frequency response, large dynamic range, high electromechanical conversion sensitivity, high mechanical performance strength, and easy matching of acoustic impedance.
The PP five-layer co-extruded solar cell back sheet can reduce production costs while ensuring good product performance, simplify the preparation process, enhance adhesion before each layer, and prevent delamination or falling off, ensuring the long-term durability of the solar cell back sheet weather resistance. The material has better electrical insulation performance, strengthens the protection of the backsheet to the cells, and ensures the service life of the cells. PP solar photovoltaic backsheet production line adopts multi-layer co-extrusion, automatic metering system, PLC control of the whole machine, realizes man-machine interface operation, and remote inspection service.
PP solar photovoltaic backsheet production line features the “one-key acceleration” function, which allows the equipment to achieve low-speed adjustment and high-speed production, greatly reducing the waste of raw materials caused by the adjustment process. With an intelligent advanced control system, network transmission speed is fast, so that the information transmission error is greatly reduced, and the speed, pressure, and material conveying of the equipment are more stable Through centralized control, it is possible to browse all information of the equipment on one screen, such as current, pressure, speed, temperature, vacuum pressure, etc., making the operation easier; the HMI human-machine interface, centralized control system, realizes one-screen browsing of the whole machine parameters, such as Temperature, pressure, speed, current, etc., easy to operate. The digital network transmission enables the equipment to quickly locate and perform remote maintenance and error analysis when a fault occurs, greatly reducing debugging and production downtime.
