At the 22nd China International High-tech Achievement Fair held recently, Fangda Carbon's new product graphene composite functional non-woven fabric was acclaimed and won the "Excellent Product Award" in one fell swoop.

Fangda Carbon introduced 4 graphene preparation and application technology patents from Lanzhou University, and built a graphene pilot line and graphene polypropylene composite masterbatch production line. The preparation process of Fangda Carbon-graphene composite functional non-woven fabrics and current Industrial devices are seamlessly connected. During the production process, the monoatomic layer graphene is uniformly dispersed, highly compatible and organically fused in the polymer matrix. The test results of authoritative inspection and testing institutions show that: the graphene composite functional non-woven fabric and its masks have an antibacterial rate of Staphylococcus aureus greater than 99%, an inhibition rate of E. coli 99%, and an inhibition rate of Candida albicans greater than 99% , Has a good antibacterial effect. Compared with conventional non-woven fabrics, graphene composite functional non-woven fabrics and their mask products will not produce microbial secondary pollution after storage, transportation and frequent wearing.

It is reported that the product has good UV radiation resistance, and the UV protection coefficient value is greater than 100. It is an excellent UV-resistant non-woven fabric material. The tensile strength of the 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 PFE of 100% for bacterial filtration, a PFE for solid particulate filtration of more than 96%, and a resistance of less than 31Pa. After the graphene modified antibacterial mask is worn, the veneer part produces less water vapor, and the facial comfort is high. The wearing time can be extended to 4 to 6 times that of ordinary masks, and no oral odor will remain on the mask during the second wear. Fangda Carbon Graphene composite functional non-woven fabrics and graphene modified antibacterial masks are expected to play a protective role in the fight against epidemics, daily protection, medical health, and health care.
