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 mask filter material can meet the above requirements.
The melt-blown material is heated, melted and extruded, and then ejected through hot air through the pores of the nozzle. Under the traction and stretching of the hot air, micron or even sub-micron level fibers are formed. The accumulation of fibers can form a filter membrane. The melt-blown filter membrane generally used for flat masks is 25g of melt-blown material.
Before the melt-blown material undergoes electrostatic electret treatment, the filtration efficiency of the melt-blown material is relatively low, about 30%-40% of the aerosol filtration performance.
The core filter material of ptfe mask filter material can filter and intercept dust and aerosol particles that are larger than its fiber pore size, thereby avoiding pathogenic microorganisms (such as viruses and bacteria), or other particles that attach to dust and aerosol particles. Harmful factors come into contact with the human body and enter the respiratory tract, greatly reducing the risk of people being infected or harmed.
The PTFE mask filter materials 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 membrane; using American Imported production and testing instruments are used to test the quality of PTFE film, and have also passed international SGS testing and certification, as well as ISI testing and certification.
