QZTC Nanotechnology has focused on one thing for more than ten years, which is to do nano-silver. "
"At present, QZTC nano-silver film still performs stably under the test of 1 mm bending radius."
On May 17, Mr. Chen Xinxiong, Director of Application Engineering of QZTC, delivered a speech entitled "Application and Advantages of Nano-silver Wires on Folding Screens" at the "5G Folding Pathways" Forum held in Dongguan and revealed that QZTC Nano-silver The film can withstand bending more than 400,000 times.
Since Rouyu Technology, Samsung, and Huawei successively released folding screen phones, flexible screen phones have brought revolutionary business opportunities to nanosilver, and nanosilver conductive films have been regarded as the best solution for flexible screens.
"Mobile phones need bending resistance. Nano-silver is suitable for flexible and flexible touch displays." Chen Xinxiong said that QZTC's nano-silver film has excellent stretching ability and can control less than 7% of tensile force. Under the change of stretch, there is no change in the sheet resistance, and the metal grid will fail even if only 2% tensile force is applied.
In addition, after testing, QZTC nano-silver film can keep functioning normally for 1000 hours even at a high temperature of 85 ° or a low temperature of -40 °. "We simulate the conditions of sunlight and sunset, and paste the nano-silver film on the window, and the experiment can keep the function normal for more than two years."
It is understood that nano-silver wire has many advantages such as excellent electrical conductivity, high penetration, excellent stretchability, excellent bending, and no visible lines to the naked eye. Among them, due to the excellent flexibility, the nano-silver film can be evenly coated on the surface of any uneven or stepped film substrate.
"QZTC is the first company in the world to do nano-silver." Chen Xinxiong introduced that as early as 2002, Tiancai Innovation had a nano-silver patent.
Since its official establishment in 2004, QZTC is currently the company with the most nano-silver wire patents in the world, and has obtained 188 patents at home and abroad, covering the process of nano-silver wires, ink synthesis, films, and touch devices. Occupying more than 70% of global nano-silver wire patents, it is also the first company in the world to mass-produce nano-silver wires and successfully commercialize them.
In the years of development of QZTC' innovation, its products are not only applied to mobile phones, but also used in sensors, OLED lighting, medical products, solar cells and other industries.
It is worth mentioning that QZTC's production base in Xiamen was officially put into production recently. The monthly production capacity can reach about 7000 liters of nano silver ink, which can provide more than 700,000 square meters of nano silver transparent conductive film coating area. 35 million smart phones, or over 230,000 touch screens, will become the world's largest nanosilver production base.
