Ingabe ukhona umehluko phakathi kwemaski e-N95 kanye nemaski e-KN95?

Lo mdwebo oqondakala kalula uchaza umehluko phakathi kwemaski e-N95 ne-KN95.Amamaski e-N95 angamazinga e-mask aseMelika;I-KN95 izindinganiso zamaski zaseShayina.Nakuba kunomehluko omningi phakathi kwalezi zifihla-buso ezimbili, lezi zifihlabuso ezimbili ziyefana emisebenzini abantu abaningi abayikhathalelayo.

Umkhiqizi wemaski i-3M uthe, "Kunesizathu sokukholelwa ukuthi" i-KN95 yaseChina "ilingana" ne-United States' N95.Izindinganiso zemaski eYurophu (FFP2), Australia (P2), South Korea (KMOEL) naseJapan (DS) nazo zifana kakhulu.

Yini i-N95 ne-KN95 abafana ngayo

Womabili amamaski angathwebula u-95% wezinhlayiya.Kule nkomba, imaski ye-N95 ne-KN95 iyafana.

Ngoba ezinye izindinganiso zokuhlola zithi imaski ye-N95 ne-KN95 ingahlunga u-95% wezinhlayiya zama-microns angu-0.3 noma ngaphezulu, abantu abaningi bazothi bangahlunga kuphela u-95% wezinhlayiya zama-microns angu-0.3 noma ngaphezulu.Babecabanga ukuthi imaski ayikwazi ukuhlunga izinhlayiya ezincane kuno-0.3 microns.Isibonelo, lesi yisithombe seSouth China Morning Post.Baze bathi "imaski ye-N95 ingavimbela abagqokile ukuthi bangaholeli izinhlayiya ezinkulu kuno-0.3 microns ububanzi."

Kodwa-ke, imaski ingabamba izinhlayiya ezincane kunalokho abantu abaningi abakucabangayo.Ngokusho kwedatha ye-empirical, kungabonakala ukuthi imaski empeleni iphumelela kakhulu ekuhlungeni izinhlayiya ezincane.

Umehluko phakathi kwemaski e-N95 ne-KN95

Womabili la mazinga adinga ukuthi imaski ihlolelwe ukuhlungwa lapho ithwebula izinhlayiya zikasawoti (NaCl), zombili ngenani elingu-85 litres ngomzuzu.Nokho, kukhona umehluko phakathi kwe-N95 ne-KN95, lapha ukuze ugcizelele.

Lo mehluko awumkhulu, futhi awukho umehluko omkhulu kubantu abavame ukusebenzisa imaski.Nokho, kukhona umehluko omkhulu:

1. Uma umkhiqizi efuna ukuthola izinga le-KN95, kuyadingeka ukwenza ukuhlolwa kokuvala imaski kumuntu wangempela, futhi izinga lokuvuza (iphesenti lezinhlayiya ezivuzayo ohlangothini lwemaski) lidinga ukuba ≤8%.Amamaski ajwayelekile we-N95 awadingi ukuhlolwa kwezimpawu.(Khumbula: Lokhu kuyimfuneko kuzwelonke ezimpahleni. Izinkampani eziningi zezimboni nezibhedlela zizodinga ukuthi abasebenzi bazo benze ukuhlolwa kwezimpawu.)

2. Omaski be-N95 banezidingo zokwehla komfutho ophezulu uma uhogela.Lokhu kusho ukuthi badinga ukuphefumula okwengeziwe.

3. Amamaski e-N95 nawo anezidingo eziqinile kancane zokwehla kwengcindezi phakathi nokukhipha umoya, okufanele kusize ukuthuthukisa ukuphefumula kwemaski.

Isifinyezo: Umehluko phakathi kwemaski e-N95 ne-KN95

Indaba efingqiwe: Yize imaski ye-KN95 kuphela edinga ukuphumelela ukuhlolwa kwezimpawu, womabili imaski angama-N95 kanye namamaski e-KN95 avunyelwe ukuhlunga ama-95% ezinhlayiya.Ngaphezu kwalokho, imaski ye-N95 inezidingo eziqinile zokuphefumula.
