After the outbreak of the new coronavirus, masks have become a necessary anti-epidemic material for people.
So, what kind of mask is enough to protect against viruses, and how do masks protect us from viruses? This requires a key material, which is PTFE single-component clothing film.
Droplet transmission is a type of airborne transmission. It means that droplets containing a large number of pathogens are discharged into the environment through the mouth and nose when the patient exhales, talks, sneezes, and coughs. Generally, large droplets will spread rapidly due to gravity. Droplets fall to the ground, and some small droplets will stay in the air for a short time, causing susceptible people to become infected after inhaling them. Droplet transmission is also the main transmission route of the new coronavirus.
The filtration efficiency of ptfe single-component clothing membrane for bacteria and PM2.5 particles in the air can reach more than 95%, reaching the filtration standard of KN95 masks.
The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing.
In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception), so the interception rate will not be attenuated due to moisture in the exhaled breath.
The ptfe single-component clothing membrane produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely small objects with a diameter of 0.1um-0.3um For particles, the filtration level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
