Imaski yelaphu .. ukusebenza kwayo kunye nobomi beshelufu

Uphononongo lwaseMelika luqinisekisile ukuba iimaski zelaphu eziphinda zisetyenziswe zihlala zisebenza emva kokuba zihlanjiwe kwaye zomiswa unyaka wonke ekuhluzeni amasuntswana asemoyeni, kubandakanya namasuntswana entsholongwane. Uphononongo luqhutywe kwiYunivesithi yase "Colorado Boulder" kwaye lupapashwe kwiphephancwadi i-Aerosol kunye noPhando loMgangatho woMoya, apho uphando luqinisekisile ukuba ukubeka i-cotton mask phezu kwe-mask yokuhlinzwa, kuba ihambelana ngokugqibeleleyo nobuso, inika ukhuseleko olukhulu kunoko. yenziwe ngelaphu kuphela.

Kolu phononongo, ngokwengxelo yeNdawo yezeMpilo, izazinzulu azikhange zivavanye imaski kubantu bokwenyani, endaweni yoko, zasebenzisa le ndlela ilandelayo:

*Yenza izikwere ezininzi zomqhaphu owalekwe kabini.

*Yayihlanjwa yomiswa ngaphezulu nangaphezulu kwamaxesha angama-52, eli nani lokuhlanjwa kweveki ngonyaka.

*Ibhokisi yomqhaphu ivavanywa phakathi kwemijikelo esixhenxe yokucoca.

*Kuvavanyo, umqhaphu uncanyathiselwe kwelinye icala lefuneli yentsimbi.

Ngokusebenzisa le funnel, abaphandi bakwazi ukulawula ukuhamba rhoqo komoya kunye neengqungquthela zomoya, kunye nokulinganisa umphumo wokuphefumla kwimaski, abaphandi badala iimeko ezingokoqobo zobomi bokwenene, kunye namanqanaba aphezulu omswakama kunye namaqondo okushisa.

Emva kokuhlamba ngokuphindaphindiweyo kunye nokomisa, nangona i-cotton fibers square fibers yaqala ukuphuka, ayizange itshintshe amandla okucoca imaski.

Ekuphela kwesiphumo esibi yayikukunyuka okuncinci kokumelana nokuphefumla, okuthetha ukuba imaski yaba nzima ukuphefumla emva kokuhlamba kunye nokomisa amatyeli aliqela.

Kuxelwe ukuba ukusukela oko kwaqala ubhubhani wentsholongwane kaCorona, amawaka eetoni zenkunkuma yezamayeza iveliswa kwihlabathi liphela mihla le, uninzi lwayo lubandakanya iimaski ezilahlwayo.

Ngokutsho kombhali wophononongo: "Ekuqaleni kobhubhane, besizikhathaza ngokuphuma sikhe sihambe sikhe sihambe siye edolophini, sibone zonke ezi maski zilahlwayo zingcolisa indalo."

Yeyiphi eyona imaski ilungileyo ngexesha lobhubhane?

Ngaphandle kokusetyenziswa kwakhona kweemaski zomqhaphu, uphononongo lukwabonise ukusebenza kwazo, kwaye iimaski zotyando, kunye neemaski zomqhaphu ezifakelwe phezu kweemaski zomqhaphu, zingcono kuneemaski zomqhaphu.

Ngokophononongo, iimaski zomqhaphu zihluzwe malunga neepesenti ezingama-23 zobukhulu besuntswana elincinci, ii-microns eziyi-0.3, apho intsholongwane inokuhambisa khona.

Ukusebenza kweemaski zotyando bekungcono kakhulu kuba bezihluza phakathi kwe-42-88% yamasuntswana amancinci, ngelixa ukusebenza kakuhle kweemaski zomqhaphu ngaphezulu kweemaski zotyando bekumalunga nama-40%, kwaye iimaski ze-KN95 kunye ne-N95 yayizezona zibalaseleyo njengoko zihluza i-83-99. I-% yamasuntswana acolekileyo.

Uqhubana njani nomntu ongakuhoyiyo ngobukrelekrele?
