Ngaba kukho umahluko phakathi kweemaski ze-N95 kunye neemaski ze-KN95?

Lo mzobo kulula ukuwuqonda ucacisa umahluko phakathi kwe-N95 kunye ne-KN95 imaski.Iimaski ze-N95 ziyimigangatho yemaski yaseMelika;I-KN95 yimigangatho yemaski yaseTshayina.Nangona kukho iiyantlukwano ezininzi phakathi kwezi zigqubuthelo zobuso, ezi zigqubuthelo zobuso ziyafana kwimisebenzi ekhathalelwe ngabantu abaninzi.

Umenzi wemaski u-3M uthe, "Kukho isizathu sokukholelwa ukuba" i-KN95 yaseTshayina "ilingana" ne-United States' N95.Imigangatho yemaski eYurophu (FFP2), i-Australia (P2), iSouth Korea (KMOEL) kunye neJapan (DS) nayo ifana kakhulu.

Yintoni i-N95 kunye ne-KN95 ezifanayo

Zombini iimaski zinokubamba i-95% yamasuntswana.Kwesi salathisi, iimaski ze-N95 kunye ne-KN95 ziyafana.

Kuba eminye imigangatho yovavanyo ithi iimaski ze-N95 kunye ne-KN95 zinokuhluza iipesenti ezingama-95 zamasuntswana e-0.3 microns okanye ngaphezulu, abantu abaninzi baya kuthi banokuhluza kuphela i-95% yamasuntswana e-0.3 microns okanye ngaphezulu.Bacinga ukuba iimaski azikwazi ukuhluza amasuntswana amancinci kune-0.3 microns.Umzekelo, lo ngumfanekiso weSouth China Morning Post.Bade bathi "iimaski ze-N95 zinokuthintela abanxibi ukuba bangaphefumli amasuntswana amakhulu kune-0.3 microns ububanzi."

Nangona kunjalo, iimaski zinokubamba amasuntswana amancinci kunokuba abantu abaninzi becinga.Ngokwedatha yobungqina, kunokubonwa ukuba iimaski zisebenza kakhulu ekuhluzeni amasuntswana amancinci.

Umahluko phakathi kwe-N95 kunye ne-KN95 imaski

Yomibini le migangatho ifuna ukuba imaski ivavanyelwe ukuhluzwa xa ibamba iincinci zetyuwa (NaCl), zombini kwizinga le-85 ilitha ngomzuzu.Nangona kunjalo, kukho umahluko phakathi kwe-N95 kunye ne-KN95, apha ukugxininisa.

Lo mahluko awukho mkhulu, kwaye akukho mahluko ungako kubantu abasebenzisa iimaski ngokubanzi.Nangona kunjalo, kukho umahluko obalulekileyo:

1. Ukuba umenzi ufuna ukufumana umgangatho we-KN95, kuyimfuneko ukwenza uvavanyo lokutywinwa kwe-mask kumntu wangempela, kwaye izinga lokuvuza (ipesenti yeengqungquthela ezivuzayo ukusuka kwicala lemaski) kufuneka ibe ≤8%.Iimaski eziqhelekileyo ze-N95 azifuni uvavanyo lwetywina.(Khumbula: Le yimfuneko yelizwe jikelele kwiimveliso. Iinkampani ezininzi zemizi-mveliso kunye nezibhedlele ziya kufuna ukuba abasebenzi bazo benze uvavanyo lokutywinwa.)

2. Iimaski ze-N95 zineemfuno ezisezantsi zoxinzelelo oluphezulu ngexesha lokuphefumla.Oku kuthetha ukuba kufuneka baphefumle ngakumbi.

3. Iimaski ze-N95 nazo zineemfuno ezingqongqo kancinci zokwehla koxinzelelo ngexesha lokuphefumla, ekufuneka incede ukuphucula ukuphefumla kwemaski.

Isishwankathelo: Umahluko phakathi kwe-N95 kunye ne-KN95 imaski

Isishwankathelo: Nangona iimaski ze-KN95 kuphela kufuneka ziphumelele uvavanyo lwetywina, zombini iimaski eziyi-N95 kunye neemaski ze-KN95 zivunyiwe ukuba zihluze iipesenti ezingama-95 zamasuntswana.Ukongeza, iimaski ze-N95 zineemfuno ezomeleleyo zokuphefumla.
