Recently, the Chinese Academy of Sciences Chongqing successfully developed the first nano-fiber membrane anti-haze masks, using the core technology is electrospinning nano-fiber membrane, marking the final realization of China's industrialization of nanofiber equipment, and for the first time applied to the development of haze masks. Nanofiber membrane technology in China successfully industrialized in the future will be widely used in haze masks, air purification filters, haze windows and other air purification.
New technology breakthrough! The first nano-fiber membrane haze masks developed successfully
After nearly eight years of tough challenges, the Chinese Academy of Sciences Chongqing Institute of Green Smart Technology recently announced that its research team successfully developed the first nanofiber membrane environmental protection haze masks, and to achieve industrial applications.
The main person in charge of scientific research, Chinese Academy of Sciences Chongqing Institute of Green Intelligent Technology researcher Ren Wei introduction, before that, only the Czech environmental technology companies to achieve nanofiber membrane industrialization. However, the company sells only nanofiber equipment and does not sell related products, and mainly cooperates with the United States in the field of automobile filter.
Ren Yiwei said that after nearly eight years of trial and several failed scientific research teams, China has finally realized the industrialization of nanofiber equipment. For the first time, it has been applied to the research and development of haze masks and has obtained at least six technical patents. "This is extremely exciting in the field of nanofiber technology innovation in our country," Ren said.
According to reports, the full name of the mask, "Zhong Kelai new nano-fiber membrane efficient anti-haze masks," the core technology used by the Chinese Academy of Sciences, Chongqing Institute of Green Smart Technology and Industrial Research Institute jointly developed electrostatic spinning nanofibrous membrane. The technology with high filtration accuracy, fiber diameter can be controlled within the range of 50nm-5um, 0.99um particulate matter filtration efficiency of 99.99%, on bacteria, viruses can achieve 100% interception.
"The unique high efficiency electrospun nanofiber membrane technology used in masks, with high filtration efficiency characteristics, high efficiency filter PM2.5 and its carrying a variety of harmful microorganisms, heavy metals, dust, pollen, influenza virus, automobile exhaust fumes On the human body violations, the effective rate of ≥ 95%. "Ren Yiwei introduction, this anti-haze masks unique cold expiratory valve, the timely discharge of hot air moisture, reduce eye fog.
Ren Yiwei pointed out that the haze masks on the domestic market now use physical interception plus electrostatic adsorption technology, but the electrostatic adsorption material adsorption a certain amount, the filtration accuracy will be greatly reduced. China's research team developed a haze masks rely on nano-fiber membrane to achieve purely physical interception. In addition, because the nano-fiber is very thin, the mask's air permeability is greatly enhanced, the wearer does not appear hot and suffocating phenomenon.
All along, the nanofiber technology in the field of clothing, batteries rapidly charging the area, the artificial skin has a more extensive field of medical applications. Today, nanofiber membrane technology in China successfully industrialized in the future will be widely used in haze masks, air purification filters, anti-haze windows and other air purification.
Ren Yiwei revealed, then, nanofiber membrane environmental haze masks will be through the mask vending machines, appeared in the airport, high-speed rail, high-end supermarkets and other areas, the public can purchase their own, the market price of 16 yuan a. It is reported that research teams are planning to build the first industrial base of nanofibers.
