Zhou Tao, general manager of China Nanocomposite Zirconia Ceramic Mobile Phone Backplane Manufacturer NTTZ Ceramic Materials Technology Company, gave a lecture on "Inorganic / Organic Molecular Assembly Materials (Hejing China) Application Exploration in 5G Mobile Phone Backplane. This marks that NTTZ's carefully-developed nano-polycrystalline cell phone backplane, which lasted two years and cost tens of millions of yuan, is about to enter the market.
Nano-crystalline porcelain is essentially a nano-scale inorganic ceramic molecular unit and organic polymer monomers and prepolymers aggregated into a multi-layered, multi-component, multi-level interface of three-dimensional structure of functional materials, like a shell in nature , Coral, pearls, teeth and bones, after processing and polishing, they are as warm as jade, and some trace metal ions are colorful. It has created a new category of mobile phone backplane material selection. From the perspective of performance indicators, the mobile phone backplane made of nanocrystalline porcelain has the characteristics of high aesthetics, good wear resistance, strong heat dissipation, and excellent anti-drop performance. It also has good 5G signal permeability. From the perspective of mass production feasibility indicators, nano-crystalline ceramic raw materials have a high technological content. When used to make mobile phone backplanes, a special injection molding process and molecular assembly post-processing technology are used to produce high efficiency and high yield, which is effective Reduced production costs. The most subversive is that Nano-Porcelain can directly make a 3D mobile phone backplane with a concentrated frame and cover, which saves the configuration of the metal frame for low-end models, greatly improving the profitability of mobile phone brand manufacturers space.
Zhou Tao, general manager of NTTZ, emphasized that nano-ceramics is not a standard formula of specific material varieties, but a new material category that uses a molecular assembly process to combine inorganic nano-ceramics and organic polymer components. The specific formula and production process of the raw materials can be set according to the individual needs of the application side of the mobile phone backplane. Starting from nano-ceramics, 5G mobile phone backplane materials will enter the custom era.
Shen Xiaoyang, technical director of NTTZ, said that prior to the advent of nanocrystalline ceramics, existing mobile phone backplane materials such as metal, glass, plastic, etc., are all general-purpose materials. The idea of selecting mobile phone backplane materials is based on the market of mobile phone models Positioning (high, middle and low end), taking into account the needs of mobile phone technical solutions, select the appropriate variety from the existing materials to configure. After the advent of Nano-Porcelain, the original market structure will be broken. A new industrial ecological chain based on the custom technology of Nano-Porcelain and Tongwan new material mobile phone backplane materials will grow rapidly. And expand.
In February 2020, with the global outbreak of Coronavirus (covid-19), the NTTZ nano-ceramics R & D team and the expert team of Nanjing Medical University, after more than a month of rigorous and meticulous feasibility investigations, established a cooperative R & D antibacterial version of nano-ceramics The research goal of crystal new materials.
As the most important personal information processing platform in daily life, mobile phones have become a breeding base for a large number of bacteria on their outer surfaces, mainly including E. coli, Staphylococcus epidermidis, Staphylococcus aureus, and Bacillus. When making phone calls, pathogenic bacteria will contact the face and other parts of the body and cause infection. Therefore, the selection and determination of suitable bacterial inhibitors to minimize the activity of common pathogens and viruses on the outer surface of mobile phones is an important point in the research and development process of bacteriostatic nano-crystalline ceramic materials.
At present, the main idea is that metal ions are incorporated into nanocrystalline ceramic materials, and the bacteriostatic effect is achieved by slowly releasing metal ions. At present, the silver ion antibacterial technology is the safest, the highest sterilization rate, and the most environmentally friendly technology against harmful bacteria. Its principle is to use the ultra-reducing power of nano silver ions to strongly attract the sulfhydryl groups on bacterial proteases to prevent cell metabolism. Interfere with the synthesis of microbial DNA, causing it to lose its ability to divide and reproduce and die. In addition to studying the inhibitory effect on bacteria, shortening the survival time of viruses on the surface of mobile phones is another goal of our research. Studies have shown that the survival time of influenza A H1N1 flu virus on the surface of objects of different materials is quite different. It lasts 48 hours on wooden surfaces to maintain the ability to infect, and the survival time on stainless steel and plastic surfaces is generally about 24 hours. Nano-silicon ceramics containing silver ions can further reduce the survival time of viruses on the surface of mobile phones and reduce the possibility of infection to humans.
Zhou Tao, general manager of NTTZ, revealed that the current research and development of the project is progressing well, and it is expected that the antibacterial version of nano-crystalline ceramic materials will be launched in about two months.
