Kungani isitifiketi se-ffp2 kunzima kangaka ukusithola|KENJOY

Ngaphezu kwezindleko eziphakeme zokuhlola, izindawo zokuhlola eYurophu, isikhathi eside senqubo nezinye izici, izindinganiso eziqinile zokuhlola zivimbele abakhiqizi abaningi bamaski.OkulandelayoI-FFP2 imaski ukuhlolwa kokusebenza kahle kokuhlunga kanye nokuhlolwa kokumelana nokuphefumula njengezibonelo zokukhombisa izinga eliphezulu lokuhlola.

Ukucaciswa okujwayelekile kwama-FFP2 okuphefumula okuvikela

Womabili amamaski okuvikela aseYurophu naseMelika aqokwe ukuthi ahlolwe amathuluzi aseMelika we-TSI-8130Automated Filter Testers.Isigaba esijwayelekile saseMelika sisebenzisa indlela ye-NaCl, isigaba R sisebenzisa indlela ye-DOP, kanti izinga laseYurophu lisebenzisa indlela ye-DOP.Ukuhlola kwaseYurophu kusebenzisa uwoyela we-DOP ukukhiqiza uthuli.Ububanzi bezinhlayiya zikawoyela we-DOP ngu-0.33 μ m, ububanzi obuphakathi bokubala ngu-0.20 μ m, futhi ukusebenza kahle kokuhlunga kuyadingeka ukuthi kungabi ngaphansi kwama-94%.Ngakolunye uhlangothi, umphumela wokuhlunga uhlobene nosayizi wezinhlayiyana, ngaphezu kwalokho, kuphinde kuthinteke ukuthi izinhlayiya ziqukethe amafutha noma cha.

Ngaphezu kwalokho, amazinga okuhlola umoya we-EU we-FFP2 respirators nawo aqinile kakhulu.Ukuhlolwa kokumelana nokuphefumula kusebenzisa izinga lokugeleza kwe-95L/min futhi ukuhlolwa kokumelana nokuphelelwa yisikhathi kusebenzisa izinga lokugeleza lika-160L/min.Ukuhlunga okuqinile okunjalo namazinga okumelana nokuphefumula kwenza abakhiqizi abaningi bahlehle ngokuqondile.

Izinto ezintsha ezisezingeni eliphezulu ze-nano

Amazinga okuhlola aqinile okusebenza kahle kokuhlunga kanye nokumelana nokuphefumula kwenza imaski ye-FFP2 ibe nezidingo eziphakeme zezinto zokuhlunga.Ukusebenza kahle kokuhlunga kuhlolwe yi-DEKRA ukuze kudlule ama-96%.Ivikela impilo yabantu ngokuhlunga futhi ivimbele ukungena kwezinto eziyingozi njengezinhlayiya zothuli, amagciwane, amagciwane kanye nezinhlayiya ezinamafutha emoyeni.I-surface morphology ye-nano-material entsha iyisakhiwo se-spider-web-microporous, into eguquguqukayo futhi enwebekayo ye-microporous ene-porosity ephezulu, ukusabalalisa okufanayo kosayizi we-pore, ukungena komoya kanye nokungena kwamanzi.Ngesikhathi esifanayo, ibuye ibe nomsebenzi wokuphefumula ukuze kuqinisekiswe induduzo yokugqoka.Impahla iyimpahla esebenza kakhulu enokumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala, ukuqina okukhulu namandla, nokuvumelana okuhle kwe-biocompatibility.I-fiber kanye nosayizi we-pore we-nano-material kusezingeni le-nanometer, futhi ingavimba ngokuqondile amabhaktheriya, amagciwane kanye nothuli ngokusebenzisa isenzo sokuvimbela ngokomzimba.

Yingakho isitifiketi se-ffp2 kunzima kakhulu ukusithola.Uma ufuna ukwazi okwengeziwe ngamamaski e-ffp2, sicela ukhululeke ukusithinta.
