Ithetha ntoni ikhowudi kwisigqubuthelo semaski se-ffp2|KENJOY

ffp2 iimaskibanamandla okucoca aphezulu, kungekuphela nje ukuthintela iibhaktheriya ukuba zisasazeke kubantu abakufutshane nakwiindawo ezingqongileyo, kodwa nokuthintela umntu onxibileyo ukuba angosulelwa ngabantu okanye indawo engqongileyo.Nangona kunjalo, kubalulekile ukuba iimaski ze-ffp2 ziqinisekiswe.

ikhowudi kwi ffp2 imaski

Iimaski eziqhelekileyo ze-FFP2 zithengiswa kwimarike, kunye ne-logo ye-'CE' kwiphakheji kunye nekhowudi enamanani amane ukuchonga amaziko aqinisekisa ukuba imveliso ihambelana nemigangatho yaseYurophu.Umthamo wokuhluza imaski eqhelekileyo ye-ffp1 (hayi imaski yotyando) ngama-72%.Umthamo wokucoca imaski ye-memffp2 yi-95%, okuthetha ukuba inokucoca amasuntswana amancinci kunye namathontsi ajikeleza emoyeni.Uphando olutsha lubonisa ukuba ukunxiba iimaski ze-ffp2 ngokuchanekileyo kunokunciphisa umngcipheko wosulelo lwebhaktheriya ukuya kwi-0.1 yeepesenti.

Kukho iintlobo ezininzi zeemaski ze-ffp2 onokukhetha kuzo: kunye okanye ngaphandle kweevalve, eyokuqala ikhusela umntu onxibe imaski, ngelixa le yokugqibela ikhusela umntu oyinxibileyo kunye nabanye.Okulahlwayo kunye nokuphinda kusetyenziswe, ukulahla kunokubonwa ngee-initials ze-NR, ngelixa ii-initials eziphindaphindiweyo ziyi-R. I-ffp2 esetyenziswa ngokuphindaphindiweyo kuphela iimaski ezinokuvalwa kwaye zisetyenziswe kwakhona.

Indlela ye-FFp2 yokutshabalalisa iintsholongwane

Ukubulala iintsholongwane kwiimaski ze-ffp2 ezisetyenziswa amaxesha amaninzi: ukucoca umenzi kunye nemiyalelo yokubulala iintsholongwane kufuneka isetyenziswe ngaphambi kokonakalisa amandla okucoca imaski.Enyanisweni, ezi ngcebiso zinokwahluka ngokuxhomekeke kwindawo esetyenziswayo, ukuxinwa kwezinto ezingcolileyo, ukufuma okusingqongileyo kunye nokukhusela amandla emveliso.Umzekelo, iimaski ze-ffp2 ezinxitywa ngaphandle kufuneka zisetyenziswe ixesha elide kwaye rhoqo kuneemaski ezisetyenziswa kumaziko ezonyango.

Olunye uphando lubonise ukuba phantsi kwemeko ye-vacuum enzulu kunye ne-hydrogen peroxide enomphunga (VHP), umthamo wokuhluza usenokugcinwa kwi-95% emva kwamaxesha angama-25 obushushu obuphantsi bokubulala iintsholongwane.Nangona kunjalo, eyona nkqubo yobuchwephesha yokuvala inzala ifumaneka kuphela kwizibhedlele nakwiilabhoratri zeekhemikhali, ezinokunceda ngokufanelekileyo ukusombulula ingxaki yokunqongophala kwezinto kwizifo ezizayo.

Oku kungasentla sisingeniso sokuba inani elikwimaski lithetha ntoni.Ukuba ufuna ukwazi ngakumbi malunga neemaski zeffp2, nceda uzive ukhululekile ukuqhagamshelana nathi.
