Iimaski ze-N95ziqinisekiswa yi-arhente ye-NIOSH e-United States, kwaye ziimaski ezinokhuseleko olungenawo ioli olungekho ngaphantsi kwe-95%.Iimaski ze-KN95zihambelana nomgangatho kazwelonke waseTshayina "i-GB2626-2006-Isixhobo soKhuseleko sokuphefumula-Self-priming Filtering Anti-particulate Respirator", kunye ne-oily Imaski ene-particle yokukhusela ukusebenza kakuhle engekho ngaphantsi kwe-95%.

Iimaski ze-kn95 Umthengisi okumgangatho ophezulu

Ngokumalunga nokuhlelwa kwemveliso kunye nokusebenza kakuhle kokucoca, amanqanaba okukhusela e-N95 kunye ne-KN95 alingana.I-N okanye i-KN ithetha ukuba isetyenziselwa ukukhusela amasuntswana angenawo i-oyile (njengeentsholongwane, iibhaktheriya, uthuli, njl.), kunye ne-95 ithetha ukuba ukusebenza kakuhle kokucoca imaski ≥95% phantsi kweemeko zokuvavanya ezichazwe kumgangatho.Ke ngoko, ukunxiba iimaski ze-N95 okanye i-KN95 ngokuchanekileyo kunokunciphisa ukuvezwa kwe-pathogenic microorganisms emoyeni kwaye kuthintele ngokufanelekileyo iintsholongwane ukuba zingangeni emzimbeni womntu zisuka kwindlela yokuphefumla.

Iintsingiselo zeemaski ze-N95 kunye ne-KN95 ziyafana.I-N95 ngumgangatho wangaphandle, ngakumbi umgangatho waseMelika, kwaye i-KN95 ngumgangatho wasekhaya.Phakathi kwabo, i-N ithetha ukuba ayichasananga neoli, oko kukuthi, ayinayo impembelelo eninzi kwizinto ezinamafutha;I-95 ithetha impembelelo yokuthintela kwezinye iibhaktheriya, iintsholongwane kunye nezinye ii-microorganisms kunye namasuntswana, anokufikelela ngaphezu kwe-95%.
Ke ngoko, zombini ezi maski zifanelekile ukuba zisetyenziswe ngabasebenzi bezonyango kwisebe lezifo ezosulelayo, ngakumbi ubhubhani wangoku, kufuneka zinxitywe.Iimaski zonyango eziqhelekileyo zifanelekile kuphela kumasebe aqhelekileyo kunye nabemi.
Ezi ngcebiso zingentla zenzelwe ireferensi kuphela, kwaye uviwo olukhethekileyo kunye nonyango kufuneka kuboniswane nogqirha oqeqeshiweyo.

IiMaski ze-KN95 ezilahlwayo-Ngokuchasene ne-PM2.5 (umvelisi wemaski we-KN95 e-China, umthengisi weemaski we-KN95 e-China)

Iimaski ze-KN95 ziimaski ezisebenza ngokusulungekileyo ngaphezulu okanye zilingana ne-95% yento ethile kwilizwe lethu, kwaye iimaski ze-N95 ziimaski ezinomsebenzi wokuhluza ngaphezulu okanye olingana ne-95% yento ethile e-United States.Ezi zimbini zingamagama ekhowudi ahlukeneyo, kodwa eyona mpembelelo iyafana.Kwakhona, qiniseka ukuba uhlamba izandla zakho ngaphambi kokuba unxibe imaski.Emva kokususa imaski, kunqanda ukubamba umphandle wemaski.

Iimaski ze-N95 kunye ne-KN95 ngumahluko kuphela kwimodeli kunye negama, kwaye eyona siphumo siyafana.Inqanaba le-N95 ngumgangatho waseMelika, kwaye inqanaba le-KN95 ngumgangatho waseTshayina.Iimfuno zobugcisa kunye neendlela zovavanyo zala manqanaba mabini ziyafana, kodwa ziphantsi kwemigangatho yamazwe ahlukeneyo.

Imaski engu-N95 yenye yeendidi ezilithoba zeemaski eziye zaqinisekiswa liZiko leSizwe loKhuseleko kunye neMpilo eMsebenzini.I-N ithetha i-oily particles, ngokukodwa ibhekisela ekusebenzeni kakuhle kokucoca kwe-95% phantsi kweemeko zokuvavanya ezichazwe ngumgangatho we-NIOSH.Ngethuba nje imveliso idibana nomgangatho we-N95 kwaye idlula ukuphononongwa kwe-NIOSH, ingabizwa ngokuba yi-mask ye-n95, esemgangathweni e-United States., olona lwazi luphezulu ehlabathini.
Iimaski ze-KN95 ziimaski ezinobuchule bokucoca into ethile kwilizwe lam, kwaye ukusebenza kakuhle kokucoca kungaphezulu okanye kuyalingana nama-95%.Isitshixo sokunxiba imaski kukuqina kobuso, ke kuya kufuneka ufunde imiyalelo ngononophelo phambi kokuba uyinxibe, kwaye uhlambe izandla zakho phambi kokuba uyinxibe ukunqanda ukubamba ngaphakathi kwimaski ngezandla zakho.
