For different manufacturers, the production of EVA parameters are also each are not identical, hot and humid, ultraviolet aging resistance, light transmittance, material uniformity, stability and consistency and so on also have bigger difference.Now on sale in the market of EVA film solar energy equipment, its fundamental use temperature at 80 ℃, can ensure that is stable under 120 ℃, but when the temperature rises to 150 ℃ or higher, the EVA solar film equipment performance will drop rapidly.
What are the main EVA film solar energy equipment, features?
From the outside, we mainly from the respect such as thickness, width, shape, soft hard to judge the quality of the EVA film solar energy equipment.
A, thickness: EVA solar film equipment normal production thickness of 0.5 MM, of course, can also customize according to their own requirements, most of the thickness in 0.3 1.0 MM.
Second, width: EVA solar film equipment product width can also root tree needs to be cut, the most wide of up to 995 mm, so the scope of its application is more extensive.
Appearance:, due to the different manufacturers in the production of EVA film solar energy equipment chosen pattern also each are not identical, common patterns are opened, embossing, suede, etc.Among them, the embossed surface when laminated into a vacuum, and at the time of the laminated installation tooling and suede for workers to check.Each pattern of film, has its unique characteristics.
Four, soft hard: for those soft EVA solar film equipment its melting point is relatively lower, and the more hard film its melting point is relatively higher.We use in different occasions, can undertake choosing according to the actual needs.
From the inside, we mainly through crosslinking agent, the VA content, parameters such as melt index to judge the quality of the EVA film solar energy equipment.
Added a, crosslinking agent, crosslinking agent, crosslinking degree is high, but easy ageing, easy yellowing, and adding too little can also lead to this situation.If you want to choose a good EVA solar film equipment products, formula is the key, the second is the process flow, process equipment, production environment and other factors.
VA content: when a certain molecular weight, the higher the VA content, flexibility, impact resistance, flexibility of EVA, stress cracking resistance, weatherability, caking property, compatibility, thermal sealing, weldability, radiation crosslinking, transparency, shine and density will increase, and the strength, hardness, melting point, chemical resistance, flex stress, thermal denaturation, isolation, such as reduced accordingly.We can according to the actual need of technical parameters, adjust the UA content in real time.
Three, melt index: when the VA content must be in harmony refers to the higher the liquidity of the melt body increases, and the viscosity of the melt body stress cracking resistance, tensile strength, toughness, etc will be reduced.
For any of the EVA film solar energy equipment manufacturers, only a perfectly EVA solar film equipment production line to ensure the quality of the products.In the best of our knowledge of EVA film solar energy equipment, there are many types are.For a manufacturer, we only in the case of basic equipment, can provide the most considerate service for many customers.EVA solar film equipment the establishment of the production line is the core of a factory operation, in mass production, improve process was the key to improve the production efficiency.
