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 To achieve high filtration through pure physical interception, the size of the fiber needs to reach the nanometer level. kn95 mask filter membrane can meet the above requirements.
The production of PTFE mask membrane requires the selection of non-woven fabrics with reliable quality and strict control of the total number of bacterial colonies. Chemical bonding methods should be avoided during the compounding process, and at the same time, the evaluation of the chemical substances used should be strengthened. Mask manufacturers that use PTFE mask membranes must strengthen the management of incoming material inspection, online inspection, product factory inspection and other links, and resolutely eliminate unqualified raw materials and products. The performance indicators of masks produced with PTFE mask membranes should meet the requirements of relevant national standards, among which the filtration efficiency for salt media should not be less than 90%.
kn95 mask filter membraneSmall pore size (0.05~0.45μm), even distribution, large porosity, while maintaining air circulation . Through physical screening, viruses and small bacteria are blocked on the surface of the mask, and with the help of the strong self-lubricating characteristics of polytetrafluoroethylene material, every time you exhale, the particles attached to the surface of the mask will be pushed back. Return to the environment, repeat this process, and truly achieve the protective effect without relying on electrostatic adsorption.
The kn95 mask filter membrane produced has strong hydrophobicity, chemical resistance, hydrophobicity and low wind resistance, and It can achieve high dust removal efficiency. For some extremely fine particles with a diameter of 0.1um-0.3um, the filtration level can reach H13-U16. In addition, the biaxially stretched film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company and complies with current environmental protection standards.
