Given the tiny size of the new coronavirus, ordinary masks cannot achieve long-term effective isolation and protection. Due to its high filtration efficiency, the polytetrafluoroethylene mask membrane has been called the current high-efficiency medical protective mask.
Masks should be changed every 4 hours for medical staff. Ordinary people do not need to replace the mask every 4 hours if the mask is not dirty or deformed. It can be determined according to the actual use of the mask. For example, if the mask is obviously dirty and deformed, someone sneezed on you at close range, or the inside of the mask is wet, you should replace it in time.
The filtration efficiency of polytetrafluoroethylene mask membrane for bacteria and PM2.5 particles in the air can reach more than 95%. The extremely high porosity and ultra-thin thickness of <5μm make it better breathable. Sexy, small breathing resistance, comfortable to wear. In addition, the filter membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception. The interception rate will not be attenuated due to moisture in the exhaled breath. The temperature resistance range is -195℃~250℃, and the long-term use temperature is -100℃~250℃.
The polytetrafluoroethylene mask membranes produced by the manufacturer use imported raw materials, have a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring that the ptfe membrane Production quality; using production 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.
