With the outbreak of the epidemic, masks have become an urgently needed product, and mask models have become the most discussed topic. In the past, N95 was discussed, but with people’s deeper understanding of masks, now ffp3 mask filter material has become a hot topic at the moment. one.
For the testing of FFP2 category masks, whether it is European standards or American standards, the American TSI-8130 Automated Filter Testers instrument is designated for testing.
The American standard N type uses the NaCl method, the R type uses the DOP method, and the European standard uses the DOP method.
DOP method uses DOP oil to generate dust. The diameter of DOP oil particles is an aggregated average particle diameter of 0.33 μm and a counting average diameter of 0.20 μm.
The ffp3 mask filter material is mainly due to its use of materials with smaller fiber diameters 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.
ffp3 mask filter material manufacturer specializes in the production of polytetrafluoroethylene microporous membranes. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe membrane; The materials of the products produced are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
