Nano fiber mask will be mass produced: it can be recycled for 10 days, with the protection rate of 99.99%

The nano fiber mask will be mass produced: it can be recycled for 10 days, and the protection rate is 99.99%. An epidemic situation makes the mask a necessary anti epidemic material for all people. Recently, a new type of nano fiber mask developed by Hefei Branch of Chongqing Green Intelligent Technology Research Institute of Chinese Academy of Sciences can be recycled for 20 days without pollution, with a protection rate of 99.99%.

On March 3, the reporter saw that this new type of nano fiber mask is similar to the cotton mask on the market in appearance, but the filter layer of the mask adopts the high technology of "nano fiber membrane".

According to Ren Yiwei, President of Hefei Branch of Chongqing Green Intelligent Technology Research Institute, Chinese Academy of Sciences, the filtration mechanism of nanofiber membrane is different from that of traditional melt blown cloth materials. "Traditional disposable medical masks and N95 masks mainly rely on the" electrostatic adsorption "of melt blown non-woven fabrics as the main filtering means. After contacting with water and other substances, they will gradually lose static electricity, resulting in a significant decline in filtering effect.". The nanofibers mainly rely on physical interception, and the filtration stability is higher. "

Compared with the ordinary mask, the new nano fiber mask is soft and has strong air permeability. "Due to the use of nano materials with similar size to viruses, it can effectively intercept viruses, bacteria, aerosols and other substances. At the same time, it can be reused by hot water immersion cleaning or alcohol disinfection. " Ren said that a mask can be worn for about 10 to 20 days without pollution.

"At present, Anhui Province is short of non-woven mask raw material suppliers. In order to realize the industrialization of technology, we have reached a strategic cooperation with a mask manufacturer in Hefei. It is expected that by the end of March, it will be put into the market, with a daily output of about 100000 masks." Ren said they also plan to establish a nanofiber production and processing base in Hefei to apply the technology to new energy and other fields.
