EVA film is a kind of high viscosity film material made of polymer resin (ethylene-vinyl acetate copolymer) as the main raw material, adding special additives and processing by special equipment. With the continuous research and development of EVA film, EVA film continues to mature, and domestic EVA film has become an export from import
Many people think that EVA film can only be used in interior decoration, but since 2007, Shandong Fangding Safety Glass Technology Co., Ltd(The predecessor of Fangding Technology Co., Ltd.). has successfully applied for CCC certification, which shows that EVA film meets the national requirements for outdoor engineering glass in terms of strength, transparency or adhesion. Since then, it has broken the argument that PVB is the only dry consumable used in outdoor engineering in China.
EVA film in outdoor engineering applications:
★ In March 2009, the country began to formulate, in March 2010, the official release of the national laminated glass standard stipulates that PVB film must be used for automobile glass. And building laminated glass, such as balcony guardrail, lighting roof, business Windows, glass curtain wall, PVB and EVA film can be used.
EVA light resistance, hydrophobicity, weather resistance, corrosion resistance, anti-noise effect is better than PVB, plus easy storage, simple processing technology, convenient operation, and low cost, many companies are more inclined to EVA.
Everyone in the industry knows that when the autoclave is curved laminated glass, it is necessary to use silicone bags for pre-vacuuming, and some companies in order to save costs, pre-vacuuming with disposable plastic bags, and then into the autoclave, which is very complicated and the cost is high.
But the EVA lamination furnace solves this problem: the curved laminated glass can be placed in the furnace for pre-pressure, and then into the autoclave. Now, with the development of technology, Fangding Technology Co., Ltd. has developed a curved laminated glass equipment that can be molded once, which greatly saves time and cost.
Application of EVA film on decorative glass:
Art glass such as wire, fabric, photo paper, and single layer reinforcement must be made with EVA film, especially the new art glass with real objects in the middle, such as real flowers and reed grass. Now the kind of high-grade art glass is mainly exported.
Application of EVA film on new energy glass:
The application of EVA film in new energy is mainly reflected in solar photovoltaic panels, conductive glass, dimming glass and so on. The production of solar photovoltaic panels is made of silicon wafer and circuit board with EVA film composite, usually made of laminating machine; Conventional conductive glass can be made conductive by plating a conductive film (ITO film) on the surface of ordinary glass. Now the conductive glass is a laminated glass made of EVA film and conductive film, and some of the glass is also sandwiched with LED, which is more beautiful and generous.
Switchable glass is a new type of special photoelectric glass product which intercalates the liquid crystal film and EVA film into the middle of two layers of glass, and then forms the intercalation structure after a certain temperature and pressure. Now the new energy glass made of EVA film has been widely used in both business and public places and family homes.
EVA film's contribution to industrial glass:
The current refrigerator door glass and washing machine panel are basically tempered glass and special materials about 3.2mm with EVA film are squeezed together at high temperature, which is both beautiful and safe.
In order to meet the needs of more customers, the research and development of EVA film is also increasing, I believe that in the near future, EVA film will also have new breakthroughs in automotive, aviation, and Marine glass.
