Imaski engu-N95zigunyazwe isikhungo se-NIOSH e-United States, futhi zingamaski ezinokuvikela okungeyona ingxenye ye-oyili okungeyona ingxenye ye-oyili engekho ngaphansi kwama-95%.KN95 imaskizihambisana nezinga lesizwe laseShayina elithi "GB2626-2006-Isisetshenziswa Sokuvikela Esiphefumulayo-Self-priming Filtering Anti-particulate Respirator", kanye nemaski engeyona amafutha Enokuvikela kwezinhlayiyana okungengaphansi kwama-95%.

I-kn95 imaski Umthengisi wekhwalithi ephezulu

Mayelana nokuhlukaniswa komkhiqizo nokusebenza kahle kokuhlunga, amazinga okuvikela e-N95 ne-KN95 ayalingana.I-N noma i-KN isho ukuthi isetshenziselwa ukuvikela izinhlayiya ezingewona amafutha (njengamagciwane, amagciwane, uthuli, njll.), futhi u-95 usho ukuthi ukusebenza kahle kokuhlunga kwemaski kungu-≥95% ngaphansi kwezimo zokuhlola ezishiwo ezingeni.Ngakho-ke, ukugqoka imaski ye-N95 noma ye-KN95 ngendlela efanele kunganciphisa ukuchayeka kuma-microorganisms we-pathogenic emoyeni futhi kuvimbele ngempumelelo amagciwane ukuthi angangeni emzimbeni womuntu esuka emgudwini wokuphefumula.

Izincazelo zamamaski e-N95 kanye ne-KN95 ziyefana.I-N95 iyindinganiso yangaphandle, ikakhulukazi indinganiso yaseMelika, futhi i-KN95 iyindinganiso yasekhaya.Phakathi kwazo, i-N isho ukuthi ayimelani namafutha, okusho ukuthi, ayinawo umphumela omkhulu kwezinye izinto ezinamafutha;95 isho umphumela wokuvimba kwamanye amagciwane, amagciwane kanye namanye amagciwane kanye nezinhlayiyana, ezingafinyelela ngaphezu kwama-95%.
Ngakho-ke, zombili lezi zimaski zilungele ukusetshenziswa ngabasebenzi bezokwelapha emnyangweni wezifo ezithathelwanayo, ikakhulukazi ubhubhane olukhona manje, kufanele zigqokwe.Amamaski ezokwelapha ajwayelekile afanele iminyango evamile kanye nezakhamuzi kuphela.
Iziphakamiso ezingenhla zingezereferensi kuphela, futhi ukuhlolwa okuqondile nokwelashwa kufanele kuboniswane nodokotela ochwepheshe.

Amamaski e-KN95 AlahlwayoNgokumelene ne-PM2.5 (umkhiqizi wemaski we-KN95 e-China, umthengisi wamaski we-KN95 e-China)

Omaskandi be-KN95 bangamamaski abanekhono lokuhlunga elingaphezu noma elilingana nama-95% odaba oluthile ezweni lethu, kanti imaski engu-N95 imaski esebenza kahle yokuhlunga enkulu noma elingana nama-95% wento ethile e-United States.Okubili kungamagama amakhodi ahlukene, kodwa umphumela wangempela uyafana.Futhi, qiniseka ukuthi ugeza izandla zakho ngaphambi kokugqoka imaski.Ngemva kokukhipha imaski, gwema ukuthinta ingaphandle lemaski.

Amamaski e-N95 kanye ne-KN95 kuphela umehluko kumodeli negama, futhi umphumela wangempela uyafana ngempela.Izinga le-N95 liyizinga laseMelika, kanti izinga le-KN95 liyizinga laseShayina.Izidingo zobuchwepheshe nezindlela zokuhlola zalawa mazinga amabili ziyafana, kodwa zingezamazinga amazwe ahlukene.

Imaski i-N95 ingenye yezinhlobo eziyisishiyagalolunye zamamaski ezinhlayiyana ezigunyazwe yiNational Institute for Occupational Safety and Health.I-N isho izinhlayiya ezingewona amafutha, ikakhulukazi ibhekisela ekusebenzeni kahle kokuhlunga okungu-95% ngaphansi kwezimo zokuhlola ezicaciswe yizinga le-NIOSH.Inqobo nje uma umkhiqizo uhlangabezana nezinga le-N95 futhi udlula ukubuyekezwa kwe-NIOSH, ungabizwa ngokuthi imaski ye-n95, okuyindinganiso e-United States., ukuqashelwa okuphezulu kakhulu emhlabeni.
Amamaski e-KN95 angamamaski anokuhlunga kahle kwento ethile ezweni lami, futhi ukusebenza kahle kokuhlunga kukhulu noma kulingana nama-95%.Isihluthulelo sokugqoka imaski ukucinana kobuso, ngakho kufanele ufunde imiyalelo ngokucophelela ngaphambi kokusigqoka, futhi ugeze izandla zakho ngaphambi kokusigqoka ukuze ugweme ukuthinta ingaphakathi lemaski ngezandla zakho.
