Izifihla-buso ngokuvamile zingahlukaniswa zibe izigaba ezimbili: izifihla-buso zokuzivikela nezifihlabuso ezivamile.
Amamaski asetshenziselwa kakhulu ukuvikela umkhuhlane, Futhi izifihla-buso zokuzivikela zisetshenziselwa ikakhulukazi ukuvikela impilo yansuku zonke nokusebenza ezinhlobonhlobo zezinhlayiyana.Ngokwento evikelwe Amamaski okuzivikela angahlukaniswa abe imaski yokuzivikela yansuku zonke, imaski yezokwelapha, imaski yezimboni. , kanye nezifihla-buso
Izifihla-buso, izifihla-buso zemayini yamalahle nokunye.
Imaski yokuzivikela yansuku zonke, eyaziwa nangokuthi imaski yomphakathi, ibhekisela kulabo abasetshenziswa ekuphileni kwansuku zonke .Isisetshenziswa sokuzivikela esigqokwa izakhamuzi zaseShayina ukuze sihlunge izinhlayiya emoyeni ongcolile. Kubasebenzi abavela kuzo zonke izizinda .Ngezidingo zezisebenzi zokusebenzisa imaski, ekhaya nakwamanye amazwe baye bahlakulela izindinganiso ezithile eziyisibopho zamamaski okuzivikela, izinhlayiya. Kokubili ukuvikela ngokomzimba kanye nokumelana nokuphefumula kuyisivivinyo esibalulekile salezi zimaski ezikhethekile. Izazi ekhaya nasemazweni angaphandle zenze izifundo eziningi mayelana nokuvikelwa kwengxenye yazo zonke izinhlobo zamamaski, okuhlanganisa nocwaningo ngomthelela wesivinini sokugeleza komoya ekusebenzeni kahle kokuhlunga kanye nocwaningo ngomthelela wezinga lokuphefumula ekusebenzeni kahle kokuhlunga, kanye nocwaningo. ekusebenzeni kahle kokuhlunga kwamamaski e-N95 ngaphansi kokujikeleza kanye nesivinini sokugeleza okuqhubekayo Kuleli phepha, izinga lokuvuza kanye nomthelela wokuhlunga kwemaski omlilo kwacwaningwa, futhi kwacwaningwa imaski yezokwelapha kanye nemaski e-N95.
Ucwaningo lokuqhathanisa lokusebenza kahle kokuhlunga kanye nokuthuthukiswa kochungechunge lwemishini yokuhlola ehlobene.Phakathi kwazo, ku-particle.Ukuvikelwa kuhloswe kakhulu ekusebenzeni kahle kokuhlunga kanye nokufaneleka kwezinto zokuhlunga kwacwaningwa.
Izakhiwo zokuvikela zemikhiqizo yemaski zikhuthaze ukuthuthuka okushesha nokusebenza kahle kwemboni yemaski.Kodwa-ke, esikhathini esedlule, bekukhona kuphela izindinganiso zemaski yezokwelapha kanye nezindinganiso zemaski zokuvikela zezimboni eChina, okubangele ukuphazamiseka kwemakethe yemaski yomphakathi kanye nekhwalithi engalingani. Abantu bebengazi ukuthi yiluphi uhlobo lwemaski olubafanele uma bethenga imaski.
Ngomhla lu-1 kuNovemba 2016, i-GB/T 32610-2016, indinganiso yokuqala kazwelonke yase-China yamamaski okuvikela umphakathi, Izicaciso Zobuchwepheshe zamamaski okuvikela nsuku zonke, yasetshenziswa ngokusemthethweni.
Izinga lisebenza ekungcolisweni komoya empilweni yansuku zonke. Amamaski okuzivikela agqokwa umphakathi jikelele ukuze ahlunge izinhlayiya azikwazi ukusetshenziswa kwezinye izindandatho ezine-hypoxic.Umhloli Wokumelana Nokuphefumulaesetshenziswa endaweni, ukusebenza ngaphansi kwamanzi, ukuphunyuka kanye nokulwa nomlilo kanye nezinye izimboni ezikhethekile. Kuphinde kushiwo ngokucacile ukuthi izinga alisebenzi ezindabeni zokuvikela ukuphefumula kwezinsana nezingane. Umphakathi jikelele kufanele ukhethe i-civil respirator ngokwemigomo emithathu yokuvikela ukuphefumula, ukuphepha kanye nenduduzo yokuphefumula. Ngokwalolu cwaningo, ucwaningo lwamanje mayelana nokuvikelwa nokuphepha komamaski seluphelele uma kuqhathaniswa, futhi ngenxa yokuduma kwezifihla-buso, abantu banaka kakhulu ukunethezeka kokuphefumula kwamaski.
Ucwaningo lwenduduzo yokuphefumula lugxile ekugqokeni imaskhi yobuso lapho ucwaningo lokumelana nokuphefumula, ngokwezinga likazwelonke ezweni lethu njengamanje kuboniswa ukuthi umkhawulo wokumelana nokuphefumula omile kuphela, lo mkhawulo kanye nokuthuthukiswa kwemboni yemaski, kancane kancane unciphisa, imaski yesikhathi esizayo. imboni izobheka ukuphepha okuphezulu, ukuvikelwa okuphezulu, ukumelana nokuphefumula okuphansi ekuqondeni kwentuthuko.
