PVB EVA POE CAST FILM EXTRUSION LINE
PVB EVA POE CAST FILM EXTRUSION LINE
PVB/SGP/EVA film is a thermo-plastic film made of PVB/SGP resin and plasticizer. It is widely used for interlayer of construction glass, automobile, solar photovoltaic glass, bullet-proof glass, sound proof glass, etc. Features high safety, sound proof, ultravio let-proof, and can be colorful or super transparent, and used for construction wall glass for more than 70 years. Also it is of Optical application value, and solar photovoltaic as well.
There are two types of production method: by roller forming and water cooling forming, the thickness of final product will be 0.38-1.52mm, width will be 500-3400mm, transparent, color strip and full color film are optional.

EVA solar film extrusion line:
Automatic gravimetric feeding system makes sure variety of solid, liquid additives and raw materials high-precision feeding.
Low-temperature extrusion systems to ensure adequate mixing in the premise of plastination to prevent crosslinking additives.Special design of Casting part give the perfect solution to roller adhibition and water spalling.
Special online tempering device to get rid of inner stress. Tension control system ensure the flexible sheets conveying placidly during cooling , pulling andwinding process.
The on-line thickness measuring and defect inspecting system can provide real-time feedback of the production quality of EVA solar film.
EVA/POE solar Film Extrusion Line advantage editing
High transparency and high adhesion can be applied to various interfaces, including glass, metal and plastics such as PET.
Good durability can resist high temperature, moisture, uv and so on.
Easy storage. When stored at room temperature, EVA’s adhesion is not affected by humidity and water absorbent film.
Compared with PVB, it has stronger sound insulation effect, especially high frequency sound effect.
Low melting point, easy flow, applicable to all kinds of glass laminating processes, such as embossed glass, tempered glass, bent glass, etc.
Product performance editing
EVA film is used as laminated glass, which fully complies with the national standard of laminated glass, gb9962-99. Take 0.38mm thick transparent film as an example, and the performance indicators are as follows:
Project indicators project indicators
Tensile strength (MPa) = 17 visible light transmittance (%) = 87 fracture elongation (%) = 650 fog rate (%) 0.6
The bonding strength (kg/cm) is greater than or equal to 2 irradiation resistant qualified water absorption rate (%) is less than or equal to 0.15
Qualified heat resistance, qualified moisture resistance, qualified shock resistance, qualified pellet bag impact performance, qualified uv cutoff rate of 98.5%
Production equipment editor
Will make good glass vacuum bag vacuum, vacuum 700 MMHG or higher (0.092 Mpa), the temperature is 100-110 ℃ (glass surface temperature), heat preservation for 10 minutes, cooling below 60 ℃, discharge vacuum.
Because of the material characteristics of EVA, there are very high requirements when EVA is processed and shaped. According to its strict requirements on solar cell life and anti-aging, many domestic manufacturers have made great progress in formula after repeated tests.
And most of the domestic EVA film has reached the international advanced level (all indicators meet the requirements, some indicators exceed foreign products).
Due to the stringent requirements of the photovoltaic industry, the requirements for EVA production equipment are also very high.
The stability of the equipment, and the control of the shrinkage rate, as little as possible to affect the loss of formula components. The domestic manufacturer that makes film equipment has a lot of, but more or less cannot achieve the requirement.
Storage condition editing
When storage don’t take out, put them in the original packaging a cool ventilated place, and temperature not to exceed 30 ℃, humidity is below 80%.
Product specification editor
Thickness: 0.25mm, 0.38mm width: 2.1m 6. Various colors (transparent, opaque and color) are available.
Nowadays, EVA is more used in the field of solar pv, as the encapsulated film of photovoltaic modules.
