In order to avoid the risk of reduced efficiency of the mask during storage and use, electrostatic adsorption cannot be used to capture particles, and particles can only be intercepted through pure physical interception. If you want to rely on pure physical interception to achieve high-efficiency filtration, the fiber The size must reach the nanometer level, and ptfe reusable mask filters can meet the above requirements.
my country’s medical masks need to follow the standard regulations of medical surgical masks YY0469-2011 (Technical Requirements for Medical Surgical Masks). Its important technical indicators include requirements for filtration efficiency, bacterial filtration rate and respiratory resistance.
The bacterial filtration efficiency refers to the filtration efficiency of Staphylococcus aureus aerosols under specified conditions being no less than 95%, which is the original source of the N95 concept.
The ptfe reusable mask filter membrane has good antibacterial and water-repellent properties. Its characteristic is that the human body’s sweat can be emitted outwards, but outside water, bacteria and viruses cannot enter.
There are about 1 billion pores per square centimeter, with a porosity of more than 90%. The pore diameter is about 0.2 μm, which is one ten thousandth of the diameter of a water droplet, but is about 700 times larger than the size of water vapor molecules. Liquid water cannot enter Comes, sweat can pass through, thus achieving excellent waterproof and moisture permeability.
Suzhou New Material Technology Co., Ltd. is a fluorine material film manufacturer that integrates the R&D, production and sales of PTFE air filtration membranes, PTFE bubble point membranes, PTFE reusable mask filters, Teflon films and coated filter materials.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
