What material is the N95 mask made of? _ Polypropylene Professional

Original title: What materials are N95 mask made of? As of today, the domestic epidemic has come to an urgent moment, in order to tional or random fibers. Specific to the mask, its raw materials are all Polypropylene (PP). Medical masks are generally multi-layer structure, generally referred to as SMS structure. See Figure 1 and Figure 2 for schematic diagrams. Expand the full text The layers of masks we often talk about are not stipulated in the national standard GB/T 32610 for masks. If it is a medical mask, it should be at least three layers,Antivirus Disposable Mask with CE Certificate, that is, SMS (two layers of S and one layer of M). At present, the highest number of layers in China is five, that is,Medical Full Body Coverall, SMMMS (two layers of S and three (Meltblown). The fiber diameter of the meltblown layer is relatively thin, about 2 microns (μm), so it is only one tenth of the diameter of the spunbond layer, KN95 Face Mask with Five Layers ,KN95 Mask for Epidemic Prevention and Control, which plays a vital role in preventing bacteria and blood penetration. If the S spunbond layer is too much, the mask will be harder, and if the melt-blown layer M is too much, it will be more difficult to breathe. Therefore, the isolation effect of the mask can be judged from the difficulty of breathing. The more difficult it is to breathe, the better the isolation ee of Medical Protective Mask From the above explanation, N95 is actually a five-layer mask made of polypropylenawn degradation polypropylene: Z-1400, Z1500, imported metallocene polypropylene such as Basel HP461Y, MF650Y. S layer: spunbond layer Material requirements: high strength Recommended material: polypropylene with melt index of 25 ~ 60,Medical Quickly Delivery Antivirus Coverall, such as Exxon-Mobile 2040 and Shanghai Secco 2040, is a good spunbond material. For example, the performance index of S2040 is as follows: Return to Sohu to see more Responsible Editor:. zjyuan-group.com
