Corrosion resistance of disposable cloth mask filter membrane
Generally speaking, during the process of garbage incineration, some elements in the garbage will react with oxygen to form oxides and a small amount of hydrides, forming highly corrosive smoke. However, general filter materials are not very corrosion-resistant. , so people usually choose the material of disposable cloth mask filter membrane.
The raw materials of masks are all polypropylene (PP for short), and their fabrics are generally multi-layer structures, generally referred to as SMS structures. When used as anti-droplet masks, the surface material should be ensured to have high hydrophobicity. Ensure that water droplets and the bacteria and viruses in them are trapped outside.
The disposable cloth mask filter membrane is made of polytetrafluoroethylene. It is expanded and stretched to form a microporous film. This film is coated on various fabrics and substrates using a special process. Becoming a new type of filter material, the membrane has small pore size (0.05~0.45μm), uniform distribution, and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve the purpose of purification and ventilation.
No aging, no splitting, no discoloration, and strong weather resistance after long-term use.
The disposable cloth mask filter membrane produced by the manufacturer uses imported raw materials, has a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of the PTFE membrane; Production and testing instruments imported from the United States are used to test the quality of the PTFE film, and it has passed international SGS testing and certification, as well as ISI testing and certification.
