It has a protective effect. Shandong Shengquan masks write protective masks because they have protective effects. Shengquan Group is based on biomass graphene for internal heating. The unique antibacterial advantage of fiber, the newly developed double-effect antibacterial protective mask has now become a sharp weapon to resist the epidemic. Compared with foreign N95 protective mask, the mask adopts four-layer protective structure, and the original antibacterial layer of biomass graphene non-woven fabric can provide the wearer with double protection of filtration and bacteriostasis. Under the action of graphene internal heating material, the new protective mask has perfect inhibitory effect on several common strains, which can bring better antibacterial protection to users.
