        VDI Glass was established in March, 2016. The company has been committed to the large-scale production of smart glass. It took the company five years and over 200 million yuans to build a pilot line in the city of Hefei, capable of manufacturing large-size electrochromic glass. VDI adopts the latest sputtering coating process and the inorganic color-changing materials. The resulting products have been proven in the US market, with high reliability, a wide light-and-heat regulation range, and excellent energy savings.

        In order to meet huge demand in China’s domestic market, VDI Glass started to build a mass-production line in Bengbu in early 2021, which went to production in May, 2022. This plant manufactures electrochromic glass for the building applications. Its annual output is 40,000 square meters and maximum glass size is 3.0 x 1.2 meters. Since then, the company has successfully completed a dozen of construction projects. VDI Glass has now become the second supplier, after Saint-Gobain’s Sage Glass, to sell electrochromic glass for construction in China.

        Inorganic electrochromic technology, also known as all-solid-state technology, uses the electrochemical phenomenon that tungsten oxide changes color when it encounters lithium ions. The facade glass developed from this technology has a wide tuning range for the visible and infrared spectrum of solar radiation, and can save up to 30% of energy. Inorganic electrochromic technology started early. After 30 years of industrialization and spending billions of dollars, it now becomes a mature smart glass product worldwide, with a dominating market share in the smart facade applications.

        VDI smart glass is consist of three panes of glass: an outer pane of tempered glass, an electrochromic sheet, and an inner pane of tempered glass. The electrochromic sheet is glued to the inner surface of the outer pane. The outer and inner panes of glass are then sealed together to form a hollow structure with argon gas backfill. VDI's electrochromic sheet adopts inorganic dry-processing technology, having a multi-layer structure: glass substrate, transparent electrode, tungsten oxide layer, ion conduction layer, ion storage layer, and transparent electrode. When a DC voltage of about 1volt is applied between the two transparent electrodes, the lithium ions in the ion storage layer are drawn out, pass through the ion conductor layer, and enter the tungsten oxide layer, resulting coloration. When a reverse voltage is applied, the lithium ions in the tungsten oxide layer are drawn out and then enter the storage layer, and the entire device returns to its original state of transparency.

  金秋时节,秋高气爽,新葡的京集团3512vip官网于2022年9月20日在蚌埠市召开了威迪首届(1450mm*3300mm)无机电致变色玻璃(EC)产品宣导会,此次会议吸引了全国二十余家知名设计院设计师代表、各地代理商及投资者参会。

  与会期间来宾们参观了威迪无机电致变色玻璃自动化生产线,严谨洁净的生产流程,让嘉宾们直观感受到了威迪在行业内的高新技术的领先地位,也看到了威迪智能玻璃产品在未来巨大发展空间。

  来宾们还实地考察体验了公司的电致变色玻璃阳光房和产品体验室。产品体验室展示了同等环境下EC玻璃与Low-E玻璃的遮阳及隔热效果对比。实时温度显示,EC玻璃相比Low-E玻璃环境温度最高温差可达到20摄氏度以上。阳光房展示了EC玻璃在玻璃建筑中的广泛应用场景,令建筑设计师有了更多自由发挥创新设计思路。来宾们对威迪产品的节能舒适性予以极大的称赞和认可。


   产品宣导会上董事长兼总裁裴世铀博士给各位嘉宾对威迪智能玻璃进行了详细的产品宣讲,EC玻璃可通过3伏直流电实现由明到暗不同等级的采光隔热需求,可达到最佳舒适感。裴博士还分享了国外成功案例,凸显出EC玻璃在绿色建筑领域广阔的发展前景,非常符合国家双碳战略国策。


  次日,各位嘉宾受邀来到在建中的合肥市科技馆,对EC玻璃的实地项目应用进行了现场考察并给与了高度评价。并有嘉宾当场请来了未来项目的业主方现场做了考察观摩,并得到了认可。

  电致变色玻璃在建筑中的应用有着非常广阔的前景,具有智能调光,智慧节能,主动可控等特性,符合当前节能减排、低碳经济的发展需求。通过此次宣导会让大家更加真实、详细地体验威迪无机大尺寸电致变色玻璃(EC)产品特性和未来市场的巨大潜力!
