Imaski yendwangu.. ukusebenza kwayo kanye nempilo yeshalofu

Ucwaningo lwaseMelika luqinisekisile ukuthi imaski yendwangu engasetshenziswa kabusha ihlala isebenza kahle ngemuva kokuwashwa futhi yomiswa unyaka wonke ekuhlungeni izinhlayiya ezihamba ngomoya, okuhlanganisa nezinhlayiya zegciwane. Ucwaningo lwenziwa eNyuvesi yaseColorado Boulder futhi lwanyatheliswa kumagazini i-Aerosol kanye ne-Air Quality Research, lapho ucwaningo lwaqinisekisa ukuthi ukubeka imaski kakotini phezu kwemaski yokuhlinzwa, ngoba ihambisana ngokuphelele nobuso, inikeza isivikelo esikhulu kunalokho. eyenziwe ngendwangu kuphela.

Kulolu cwaningo, ngokombiko we-The Health Site, ososayensi abazange bahlole imaskhi kubantu bangempela, kunalokho, basebenzisa le ndlela elandelayo:

*Dala izikwele ezimbalwa zikakotini onezingqimba ezimbili.

*Iwashwa futhi yomiswa izikhathi ezingaphezu kwezingama-52, okuyinani lokugezwa kwamasonto onke ngonyaka.

*Ibhokisi likakotini lihlolwe phakathi kwemijikelezo eyi-7 yokuhlanza.

*Ukuze kuhlolwe, ukotini unamathiselwe ekugcineni kwefaneli yensimbi.

Ngale funnel, abacwaningi bakwazi ukulawula ukugeleza okuqhubekayo komoya kanye nezinhlayiya ezihamba emoyeni, futhi ukulingisa umphumela wokuphefumula kumaski, abacwaningi badala izimo ezingokoqobo zokuphila kwangempela, namazinga aphezulu omswakama kanye namazinga okushisa.

Ngemva kokugeza nokumiswa ngokuphindaphindiwe, nakuba imicu yesikwele sikakotini yaqala ukuwohloka, ayizange ishintshe ikhono lokuhlunga lemaski.

Okuwukuphela komphumela ongemuhle kwaba ukwenyuka okuncane kokumelana nokuhogela, okusho ukuthi imaski ibe nzima ukuphefumula ngemva kokugeza nokomisa izikhathi ezimbalwa.

Kubikwa ukuthi selokhu kwaqala ubhubhane lweCoronavirus, izinkulungwane zamathani emfucuza yezokwelapha kukhiqizwa emhlabeni wonke nsuku zonke, iningi lawo lihlanganisa imaski elahlwayo.

Ngokusho kombhali wocwaningo: "Ngesikhathi kuqala lolu bhubhane, sasizihlupha ngempela ngokuphuma sishaywe umoya noma siye edolobheni, futhi sibone zonke lezi zimaski ezilahlwayo zingcolisa imvelo."

Iyiphi imaski engcono kakhulu ngesikhathi sobhubhane?

Ngaphandle kokuphinda zisetshenziswe imaski kakotini, lolu cwaningo luphinde lwakhombisa ukusebenza kahle kwazo, nokuthi imaski yokuhlinza, kanye nemaski kakotini afakwa kumaski kakotini, angcono kunemaski kakotini.

Ngokwalolu cwaningo, imaski kakotini yahlunga cishe u-23% wezinhlayiyana ezincane kakhulu, ama-microns angu-0.3, lapho leli gciwane lingadlulisela khona.

Ukusebenza kwemaski okuhlinza bekungcono kakhulu ngoba bahlunga phakathi kuka-42-88% wezinhlayiya ezincane, kanti ukusebenza kahle kwamaski kakotini kumaski okuhlinzwa bekucishe kube ngama-40%, kanti imaski ye-KN95 kanye ne-N95 yibo abenza kahle kakhulu njengoba behlunga ama-83-99. % wezinhlayiya ezincane.

Ubhekana kanjani nomuntu ongakunaki ngobuhlakani?
