Iimaski zethu zokukhusela ze-FFP2, ngokusekwe kuvavanyo lweengxelo zovavanyo kunye nengxelo yophicotho-zincwadi lwangaphakathi kulawulo lomgangatho ngokwe-EN149 + A1: 2009 kunye nolawulo lwezixhobo ezikhuselayo (i-EU) 2016/425, ifumene isatifikethi se-CE se-European Union. Inqanaba lokhuselo yi-FFP2.
ffp2 isigqumathelo sezonyango Unogada womlomo we-FFP2 wenziwe ngoboya begusha obuphezulu. Umaleko wokuqala lilaphu elingenalukhuni elinolusu. Uluhlu lwesibini lwenziwe ngomqhaphu womoya oshushu ukuvimba amasuntswana amahle. Uluhlu lwesithathu lilaphu elinyibilikisiweyo lokucoca ulwelo. Uluhlu lwesine lilaphu elilungele ulusu elingenalukhuni. Uyilo lweemaski ezi-5 zomaleko we-ffp2 lubonelela ngokhuseleko ngakumbi kunye nokusebenza okuphezulu kokucoca kuneemaski ezisemgangathweni ezilahlwayo ezi-3.
I-ffp2 emnyama yoyilo olumnandi lwe-3D inokufezekisa ubuso obulungele wena kwaye isikhusele ngcono. Imaski yethu yotyando ye-ffp2 inamalungu ama-2 elaphu elingenalukhuni elithambileyo, nelithambileyo kwaye elinokuphefumla, alicaphukisi ulusu kwaye linokunxitywa ixesha elide ngaphandle kokuphazamiseka. Kukho ukuphefumla ngokwaneleyo ukuphefumla ngokukhuselekileyo ngesigqubuthelo sethuli.
Umbala we-ffp2 wemaski unokuhlengahlengiswa ngokobume bakho bobuso ukufezekisa okona kulungileyo. Izikhonkwane zeendlebe ezinwebekayo zinobude obufanelekileyo, zithambile kwaye ziyolula ukunciphisa uxinzelelo ezindlebeni, zilungele amadoda nabasetyhini kwaye zinokunxitywa iiyure ezininzi ngaphandle kokucaphukisa iindlebe.
I-ffp2 imask en149 isebenzisa imilo ye-3D eyilelwe ngokwemilo yobuso bomntu ukuqinisekisa ukuqina, ukunyusa umthamo wokuphefumla, ukuphucula kakhulu ukuphefumla kunye nokwenza ukunxiba kunye nomphunga ukhululeke ngakumbi. I-ffp2 yamasuntswana okucoca imaski yobuso eqinisekisa uxinizelelo, inyusa umthamo wokuphefumla wemveliso, iphucula kakhulu ukuphefumla kwaye yenza ukunxiba nokukhupha umoya kube lula ngakumbi.

Umbuzo: ngubani oqinisekisile oku njenge-ffp2?
Impendulo: Ewe ezi ziqinisekisiwe lilungu leQela leMigangatho yaseBritane (BSI) eNetherlands.
Umbuzo: Le maski ayinaso isongezo esijikeleze impumlo ukwenza itywina elingcono (l3m does) - ngoba?
Impendulo: Inocingo kwimaski enceda ukuyicofa kufutshane nempumlo.
Umbuzo: Ngaba ziyinyani?
Impendulo: Ezi ziimaski ezikumgangatho ophezulu, ezifanayo kuyilo lwe-3M 9320, endikhe ndayisebenzisa ngaphambili. Ezi zinokuphefumla kakuhle.
Umbuzo: Ngaba ezi iimaski zinokuphinda zisetyenziswe? Zihlala ixesha elingakanani?
Impendulo: Ikhowudi 'NR' emva kwekhowudi yokuqinisekiswa kwe-FFP2 ithetha ukuba 'ayinakuSebenza kwakhona'. Oku kuthetha ukuba kufuneka zingasetyenziswa ngaphezulu kweeyure eziyi-8. Oku kunokuba ziiyure ezisi-8 ezingapheliyo okanye iiseshoni zeyure eziyi-8 x 1 umzekelo. Ngokucacileyo, kokukhona usebenzisa amaxesha amaninzi, kokukhona kukho ithuba lokungcoliseka ngaphakathi.
Umbuzo: ngaba ezi zinto zisongelwe emfanekisweni - zicaba?
Impendulo: Ewe ziyagoba tyaba.
