PTFE reusable mask filter membrane is a new type of high-tech material. Compared with some common ordinary double-layer structure filter materials, it has lower resistance and higher filtration efficiency, and can be used in later processing and use. The risk of over-injury is smaller and has more prominent advantages.
The core filter material of the protective mask can filter and intercept dust and aerosol particles that are larger than its fiber pore size, thereby preventing pathogenic microorganisms (such as viruses and bacteria) or other harmful factors from adhering to the dust and aerosol particles. , comes into contact with the human body and enters the respiratory tract, greatly reducing the risk of people being infected or harmed.
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.
The ptfe reusable mask filter membranes produced by the manufacturer are all imported raw materials, with a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring the production quality of ptfe membranes ;Using production and testing instruments imported from the United States to test the quality of PTFE film, and passing international SGS testing and certification, as well as ISI testing and certification.
