Nsalu yosungunuka, yomwe imadziwika kuti "mtima" wa chigoba, ndi gawo losefera pakati pa chigoba, lomwe lingathe kusefa mabakiteriya ndikuletsa kufalikira kwa majeremusi. Monga "pakati" pa zigoba, "nsalu yosungunuka" yopangidwa ndi S2040 singagwiritsidwe ntchito kupanga zigoba, zomwe zimakhudza kwambiri momwe zinthu zilili popewa mliri.
Chinthu choyesera nsalu ya Meltblown
Nsalu yosungunuka kuti ipange lipoti la mayeso nthawi zambiri imachita mayeso okana, mayeso ogwiritsira ntchito kusefa, kuzindikira tizilombo toyambitsa matenda ndi zina zotero, nsalu yosungunuka bwino kwambiri kuti ione ngati zizindikirozi zili bwino.
Kugawa masks azachipatala
Chigoba choteteza kuchipatala Gawo 1 >;FFP2>KF94>Giredi A >KN95Zophimba nkhope >KN90/B /C /D chigoba>;Zophimba nkhope za opaleshoni>Zophimba nkhope zachipatala zotayidwa.
Gawo lofunika kwambiri la chigoba cholimbana ndi kachilombo ndi zinthu zosefera. Mphamvu yosefera ya zinthu zosefera pa tinthu timeneti imaphatikizapo kukhazikika kwa mphamvu yokoka, kutsekereza, kugundana kwa inertial, kufalikira, kulowetsedwa kwa electrostatic, ndi zina zotero. Pogwiritsa ntchito njira zosiyanasiyana zosefera, pali phindu locheperako la kusefera kwa tinthu timeneti tomwe tili ndi kukula kwa tinthu ta aerodynamic kwa 0.3 m, komwe kumadziwikanso kuti kukula kwa tinthu tating'onoting'ono kwambiri (MPPS).
