Application of PVDF solar backplane membrane: PVDF membrane is a substitute for "Tedlar", which is used in the production line of solar backplane composite materials. It can also be used in seawater desalination, sewage treatment, lithium battery diaphragm composite and outdoor building membrane engineering.

Detailed description of PVDF solar backplane film production line: PVDF film, scientific name polyvinylidene fluoride. Our gws75 production line can be used to produce 25-30 μ PVDF casting film with thickness of M and width of 1250mm, the production line speed is 20m/min, and the output can reach 120kg / h; Gws90 production line can be used to produce 25-30 μ M thick, 1250mm wide PVDF solar backplane film, the production line speed is 30m/min, and the output can reach 180kg / h; Gws120 production line can be used to produce 1-10mm thick and 1250mm wide PVDF silicon wafer pickling thick plates, with an output of about 350kg / h.

Common characteristics of PVF film and PVDF film: both are copolymers containing fluorine or fluorocarbon, which have greater chemical binding force and structural stability than any other polymer. Therefore, it will not react with pollution factors in the atmosphere, and even solvents with strong corrosion ability will not cause damage to it, so the surface of the protected metal plate is not easy to rust, and the decorative surface is not easy to fade or embrittle; It will not be stimulated by ultraviolet rays to produce changes in tissue structure, and the sun will not accelerate its "aging"; It will not change the organizational structure due to the repeated cyclic changes of the working environment temperature. The allowable temperature change value of the working environment is 180 ℃ (-70 ~ + 110 ℃), which can adapt to the outdoor environment in almost all regions of the earth: Suzhou jinweier Machinery Co., Ltd. has achieved mass production of PVDF film for PVDF solar backplane production lines manufactured for many domestic companies. The film thickness is uniform and the thickness accuracy is high. The product has been fully verified by the market. PVDF membrane is used to replace DuPont Tedlar (PVF) membrane in China, and its performance is almost the same. Welcome to visit!

PVDF film (polyvinylidene fluoride film) is a film made by salivation stretching. PVDF material has many advantages, such as high wear resistance, high corrosion resistance, high aging resistance, good heat stability, flame retardancy (low smoke), UV and nuclear radiation resistance, impact resistance, strong weather resistance, high mechanical strength and toughness, and mold resistance.

Main uses of PVDF film production line:

1. PVDF solar backplane film production line:

The film is used for solar backplane film to protect the battery, which is mainly anti-aging and wear-resistant;

2. PVDF outdoor decorative film production line:

The film is used for the protection of glass, exterior walls, doors and windows, outdoor billboards, etc. of outdoor buildings, mainly for aging resistance and wear resistance;

3. PVDF battery diaphragm production line:

Thin films are used for diaphragm applications in fuel cells and lithium ion polymer batteries;

4. PVDF filter membrane production line:

Membrane filtration membrane is used for water purification, which is divided into ultrafiltration membrane and microfiltration membrane. It is mainly used for sewage treatment, seawater desalination, and the removal of macromolecules, bacteria, sediment, salt and other impurities;

5. PVDF piezoelectric film production line:

PVDF piezoelectric film has the advantages of wide frequency response, large dynamic range, high sensitivity of electromechanical conversion, high mechanical strength, and easy matching of acoustic impedance.
