PVDF solar panel film production line

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

Detailed description of PVDF solar panel film production line: PVDF film, scientific name polyvinylidene fluoride. Our GWS75 production line can be used to produce 25-30 μ PVDF cast film with a thickness of m and a width of 1250mm, with a production line speed of 20m/min and a production capacity of up to 120KG/H; The GWS90 production line can be used to produce 25-30 μ PVDF solar panel film with a thickness of m and a width of 1250mm, with a production line speed of 30m/min and a production capacity of up to 180KG/H; The GWS120 production line can be used to produce PVDF silicon wafer acid washed thick plates with a thickness of 1-10mm and a width of 1250mm, with a production capacity of about 350KG/H.

The 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, they will not react with atmospheric pollution factors, and even solvents with strong corrosion ability will not cause damage to them. Therefore, 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 undergo changes in its tissue structure due to the intensification of ultraviolet radiation, and sunlight will not accelerate its aging; It will not undergo changes in organizational structure due to repeated cyclic temperature changes in the working environment. The allowable temperature change in the working environment is 180 ℃ (-70~+110 ℃), which can almost adapt to outdoor environments in all regions of the earth. Suzhou Jinwei Machinery Co., Ltd. has already achieved mass production of PVDF film for PVDF solar backboard production lines manufactured by multiple domestic companies. The film thickness is uniform, the thickness accuracy is high, and the product has been fully verified by the market. PVDF membrane is used domestically to replace DuPont Tedlar (PVF) membrane, and its performance is almost the same. Welcome to visit and inspect!

PVDF film (polyvinylidene fluoride film) is a thin film produced by salivation stretching processing. PVDF materials have many advantages, such as high abrasion resistance, high corrosion resistance, high aging resistance, good heat stability, flame retardancy (low smoke), ultraviolet and nuclear radiation resistance, impact resistance, strong weather resistance, high mechanical strength and toughness, and mold resistance.

The main uses of PVDF film production lines are:

1. PVDF solar panel film production line: The film is used for solar panel film to protect the battery cells, mainly with anti-aging and wear-resistant functions;

2. PVDF outdoor decorative film production line: The film is used for the protection of glass, exterior walls, doors and windows, outdoor billboards, etc. in outdoor buildings, mainly with anti-aging and wear-resistant functions;

3. PVDF battery separator production line: thin films are used for separator applications in fuel cells and lithium-ion polymer batteries;

4. PVDF filtration membrane production line: Membrane filtration membrane is used for water purification treatment, divided into ultrafiltration membrane and microfiltration membrane. It is mainly used for sewage treatment, seawater desalination, and removal of impurities such as macromolecules, bacteria, sediment, and salt;

5. PVDF Piezoelectric Thin Film Production Line: PVDF piezoelectric thin films have advantages such as wide frequency response, large dynamic range, high sensitivity to electromechanical conversion, high mechanical strength, and easy matching of acoustic impedance.
