Graphene non-woven masks are coming

"The wearing time of graphene functional non-woven masks can be extended to 4 times to 6 times that of ordinary masks and still have efficacy. No oral odor will remain on the masks when worn for the second time." Recently, the 22nd session of the Shenzhen Convention and Exhibition Center At the China International High-tech Achievements Fair, Fangda Carbon New Material Technology Co., Ltd. successfully developed new products such as graphene composite functional non-woven fabrics, graphene modified antibacterial masks and water-based graphene electric heating films, which appeared in the Gansu Pavilion. And won the "Excellent Product Award".

It is understood that graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It is considered a revolutionary material in the future. Research and application development are increasingly favored by countries all over the world.

In recent years, under the joint promotion of the Gansu Provincial Department of Commerce, the Department of Science and Technology, and the Development and Reform Commission, Fangda Carbon has introduced 4 graphene preparation and application technology patents from Lanzhou University, and has built a graphene pilot line and graphene polypropylene composite Masterbatch production line. This year, complete the construction of high conductivity graphene test line, graphene conductive ink production line and graphene electric heating film production line.

"The test results of authoritative inspection and testing institutions show that the graphene composite functional non-woven fabric and the mask made of Staphylococcus aureus have a bacteriostatic rate greater than 99%, an E. coli bacteriostatic rate of 99%, and a Candida albicans bacteriostatic rate greater than 99%, has a good antibacterial effect." Zhang Guilan, deputy director of Fangda Carbon Technology R&D Department, said that compared with conventional non-woven fabrics, graphene composite functional non-woven fabrics and their mask products are not stored, transported and worn frequently. Will produce microbial secondary pollution. At the same time, it also has very good anti-ultraviolet radiation performance. The UPF (ultraviolet protection factor) value is greater than 100. It is an excellent anti-ultraviolet non-woven fabric material, and the tensile strength of graphene composite functional non-woven fabric is twice that of conventional products. .

Fangda Carbon's graphene modified antibacterial mask has been tested to achieve a BFE (Basic Screening Engine) of 100% for bacterial filtration, and a PFE for solid particulate filtration of more than 96%. "The graphene modified antibacterial mask has the above-mentioned effects, and the veneer part of the mask produces less water vapor and high facial comfort after wearing." Bai Yongxiao, director of the China Graphene Industry Technology Innovation Strategic Alliance and professor of the School of Physics and Technology of Lanzhou University Said that Fangda's carbon-graphene composite functional non-woven fabric preparation process is seamlessly connected with existing industrial equipment. This scientific research result will play an important role in medical protection, health and daily life.
