Graphene Mask KN95

Graphene, as the king of new materials in the 21st century, the thickness of monolayer graphene is only 0.35 nm, it is the thinnest two-dimensional material in the world, with rich and peculiar physical and chemical properties, such as outstanding thermal conductivity and mechanical properties, extraordinary electron transfer properties, and certain antibacterial activity, which can be used in electronics, information, energy, physics, biomedicine and material science and other fields.
The specific surface area of graphene is large, and the electrostatic adsorption capacity of melt blown cloth produced by mixed polypropylene is super. When the air passes through normally, almost all the dust and toxic droplets will be absorbed by static electricity. Under the action of natural breathing, three-dimensional graphene is more like a natural "nano knife", which can destroy the cell wall of bacteria and play a good role in sterilization and detoxification.

The Graphene products of the company is Graphene Melt Blown Cloth, 3S graphene non-woven fabric, graphene protection masks has the characteristics such as high efficient filtering, long time bacteriostasis, comfortable to use.

Highlights：

1.Compare to the conventional mask which can only use for 4 hours, LIUSHI graphene mask can be used for 200 Hours.

2.Particle filter rate is over 99%, higher than the industry standard

3.Excellent air permeability, extremely low breath resistance, will not forming fog on the glass if you wear it, no peculiar smell for long time wearing, rich negative oxygen ion, anti-bacteria, comfortable wearing.

4.As the size of bacteria is in between 50-80nm, so it can not penetrate the graphene layer with 30-40nm aperture, in the meantime, graphene is proven to has strong sterilization effect. Double layer graphene melt blown clothes provide stronger protection.
