Malingana ndi mawonekedwe, masks akhoza kugawidwa mumtundu wathyathyathya, mtundu wopindika ndi mtundu wa chikho.Chophimba kumaso chathyathyathya ndi chosavuta kunyamula, koma kumangika kwake ndikochepa.Chigoba chopindika ndichosavuta kunyamula.Malo opumira ooneka ngati chikho ndi aakulu, koma si abwino kunyamula.
Ikhoza kugawidwa m'magulu atatu malinga ndi njira yovala.Mtundu wovala mutu ndi woyenera kwa ogwira ntchito pamisonkhano omwe amavala kwa nthawi yayitali, zomwe zimakhala zovuta.Kuvala makutu ndikosavuta kuvala ndikuvula pafupipafupi.Mtundu wovala khosi umagwiritsa ntchito mbedza za S ndi zolumikizira zofewa.Lamba wolumikizira khutu amasinthidwa kukhala mtundu wa lamba wa pakhosi, womwe ndi woyenera kuvala kwa nthawi yayitali, ndipo ndi wosavuta kwa ogwira ntchito pamisonkhano yovala zipewa zotetezera kapena zovala zoteteza.
Ku China, malinga ndi gulu la zida zomwe zimagwiritsidwa ntchito, zitha kugawidwa m'magulu asanu:
1. Masks a Gauze: Masks a Gauze amagwiritsidwabe ntchito m'magawo ena, koma zofunikira za GB19084-2003 ndizochepa.Simatsatira muyezo wa GB2626-2019 ndipo imatha kuteteza ku fumbi lalikulu la tinthu.
2. Masks osalukidwa: Zovala zodzitchinjiriza zotayidwa ndi zotchingira zosalukidwa, zomwe zimasefedwa ndi kusefedwa kwakuthupi kophatikizidwa ndi ma electrostatic adsorption.
3. Chigoba cha nsalu: Chigoba cha nsalu chimakhala ndi mphamvu yotentha popanda kusefa tinthu tating'onoting'ono (PM) ndi tinthu ting'onoting'ono.
4. Paper chigoba: ndi oyenera chakudya, kukongola ndi mafakitale ena.Ili ndi mawonekedwe a mpweya wabwino, wosavuta komanso wosavuta kugwiritsa ntchito.Pepala lomwe limagwiritsidwa ntchito likugwirizana ndi muyezo wa GB / t22927-2008.
5. Masks opangidwa ndi zinthu zina, monga zida zatsopano zoteteza zachilengedwe.
