Kuphatikiza pa chindapusa choyesa, malo oyesera ku Europe, nthawi yayitali ndi zinthu zina, miyezo yolimba yoyesa yalepheretsa opanga mask ambiri.ZotsatiraziFFP2 mask kuyezetsa bwino kwa kusefera ndi kuyesa kukana kupuma monga zitsanzo zowonetsera muyeso wapamwamba woyeserera.

Kufotokozera muyeso wa FFP2 zopumira zoteteza

Masks onse aku Europe ndi America oteteza amasankhidwa kuti ayesedwe ndi zida za American TSI-8130Automated Filter Testers.Gulu la American standard class N limagwiritsa ntchito njira ya NaCl, kalasi R imagwiritsa ntchito njira ya DOP, ndipo European standard imagwiritsa ntchito njira ya DOP.Kuyesa kwa ku Europe kumagwiritsa ntchito mafuta a DOP kupanga fumbi.Kukula kwa tinthu tating'ono ta mafuta a DOP ndi 0.33 μ m, kuwerengera pafupifupi mainchesi ndi 0.20 μ m, ndipo kusefera moyenera kuyenera kukhala kosachepera 94%.Kumbali imodzi, zotsatira zosefera zimagwirizana ndi kukula kwa tinthu, kuwonjezera apo, zimakhudzidwanso ngati tinthu tating'onoting'ono tili ndi mafuta kapena ayi.

Kuphatikiza apo, miyezo yoyezetsa mpweya ya EU ya FFP2 respirators ilinso yolimba kwambiri.Kuyesedwa kolimbikitsana kolimbikitsa kumagwiritsa ntchito kuthamanga kwa 95L / min ndipo kuyesa kwa kupuma kumagwiritsa ntchito kuthamanga kwa 160L / min.Kusefera kolimba kotereku komanso kukana kupuma kumapangitsa opanga ambiri kubwerera pansi mwachindunji.

Zatsopano zapamwamba za nano-zida

Miyezo yolimba yoyesa kusefera bwino komanso kukana kupuma kumapangitsa masks a FFP2 kukhala ndi zofunika kwambiri pazosefera.Kuchita bwino kwa kusefera kwayesedwa ndi DEKRA kupitilira 96%.Imateteza thanzi la anthu posefa ndi kutsekereza kulowetsedwa kwa zinthu zovulaza monga fumbi, mabakiteriya, ma virus ndi tinthu tamafuta mumpweya.Pamwamba kapangidwe ka nano-zinthu zatsopano ndi kangaude-ukonde ngati microporous dongosolo, amene ndi kusintha ndi zotanuka microporous zakuthupi ndi mkulu porosity, yunifolomu pore kugawa kukula, permeability mpweya ndi permeability madzi.Panthawi imodzimodziyo, imakhalanso ndi ntchito yopuma kuti iwonetsetse chitonthozo cha kuvala.Zinthuzi ndizomwe zimagwira ntchito kwambiri komanso kukana kutentha kwambiri, kukana kwa dzimbiri, kulimba kwambiri komanso mphamvu, komanso kuyanjana kwabwino kwachilengedwe.The CHIKWANGWANI ndi pore kukula kwa nano-zinthu zili mu nanometer mlingo, ndipo akhoza mwachindunji kuletsa mabakiteriya, mavairasi ndi fumbi mwa zochita zotchinga thupi.

Ichi ndichifukwa chake satifiketi ya ffp2 ndiyovuta kupeza.Ngati mukufuna kudziwa zambiri za masks a ffp2, chonde omasuka kulankhula nafe.
