Application of PVDF solar backsheet membrane: PVDF membrane is a substitute for "tedlar" and is used in the production line of solar backsheet composite materials. It can also be used in seawater desalination, sewage treatment, lithium battery separator composite, and outdoor building membrane engineering.
Detailed description of PVDF solar backsheet film production line: PVDF film, scientific name polyvinylidene fluoride. Our GWS75 production line can be used to produce thicknesses of 25-30 μ m, 1250mm wide PVDF cast film with a production line speed of 20m/min and a yield of up to 120KG/H; The GWS90 production line can be used to produce thicknesses of 25-30 μ m, 1250mm wide PVDF solar backsheet film, with a production line speed of 30m/min and a yield 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 around 350KG/H.
The common characteristics of PVF film and PVDF film are that both are copolymers containing fluorine or fluorocarbon, which have greater chemical bonding strength and structural stability than any other polymer. Therefore, they will not react with pollutants in the atmosphere, and even highly corrosive solvents will not cause damage to them. Therefore, the protected metal plate surface is not easy to rust, and the decorative surface is not easy to fade or become brittle; It will not undergo structural changes due to the intensification of ultraviolet radiation, and sun exposure will not accelerate its aging process; It will not undergo changes in organizational structure due to repeated temperature fluctuations in the working environment. The allowable temperature variation in the working environment is 180 ℃ (-70~+110 ℃), which can adapt to almost all outdoor environments on Earth. Suzhou Jinweier Machinery Co., Ltd. has already achieved mass production of PVDF solar backsheet production lines for multiple domestic companies. The film thickness is uniform, the thickness accuracy is high, and the product has been fully validated by the market. Welcome to visit and inspect!
PVDF film (polyvinylidene fluoride film) is a film made by extrusion 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.
Main uses of PVDF film production line:
1. PVDF solar backsheet film production line:
Thin films are used as solar backsheet films to protect solar cells, mainly for anti-aging and wear-resistant functions;
2. PVDF outdoor decorative film production line:
Thin films are used for the protection of glass, exterior walls, doors and windows, outdoor billboards, etc. in outdoor buildings, mainly for their anti-aging and wear-resistant functions;
3. PVDF battery separator production line:
Thin films are used as separators in fuel cells and lithium-ion polymer batteries;
4. PVDF filtration membrane production line:
Thin film filtration membranes are used for water purification treatment 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;
5. PVDF piezoelectric film production line:
PVDF piezoelectric film has the advantages of wide frequency response, large dynamic range, high sensitivity to electromechanical conversion, high mechanical strength, and easy matching of acoustic impedance.
