▎ 摘 要
NOVELTY - Graphene melt-blown filter film, comprises a first melt-blown layer (1) and a graphene melt-blown layer (2) arranged from top to bottom. The graphene melt-blown layer is composed of a mixture of spray-melt polypropylene and spray-melt graphene. The graphene melt-blown layer is a uniform hexagonal network layer. The graphene melt-blown layer is densely provided with filter holes with a diameter of less than 0.5 nm. The graphene melt-blown layer is composed of a mixture of melt-blown polypropylene and hydroxylated graphene. USE - Used as graphene melt-blown filter film. ADVANTAGE - The graphene melt-blown filter film has a simple structure, good filtering effect, and has a breaking effect on the protein of the virus, physically piercing effect, killing virus, the volume is 30-200 nm of virus can be completely blocked, the virus has 100% of blocking effect, eliminating infection bacteria, and the virus safety is more refined, more stable, the filtering effect completely satisfies the actual use requirement. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the graphene melt-blown filter film with a second melt-blown layer. First melt-blown layer (1) Graphene melt-blown layer (2) Second melt-blown layer (3)
