The main component of the ptfe reusable mask filter membrane is ptfe, which is a new type of polymer material with strong filtration efficiency and can effectively block fine particles such as viruses and bacteria.
The charge loaded on the PP melt-blown non-woven fabric does not exist permanently, but will slowly weaken until it disappears, resulting in a significant decrease in filtration efficiency. This results in the timeliness of masks using PP melt-blown non-woven fabric. , cannot be stored for a long time, and the charge disappears quickly during use, such as in a humid environment or when exposed to organic solvents. Therefore, the efficiency of masks made of PP non-woven fabrics drops significantly during storage and use. risks of.
PTFE reusable mask filter membrane is mainly due to its use of materials with smaller fiber diameter compared with traditional masks.
Generally speaking, the fiber diameter of the ordinary non-woven material used in our traditional masks is more than 1000 nanometers, while the fiber diameter of the PTFE membrane is between 100 and 200 nanometers, which is much smaller than the above diameter. Therefore, it can very effectively block PM2.5 in the air, as well as some viruses, bacteria and particles that are invisible to the human eye.
The ptfe reusable mask filter membrane 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 of ptfe membranes Quality; using production and testing instruments imported from the United States to test the quality of PTFE film, it has also passed international SGS testing and certification, as well as ISI testing and certification.
