Ubhubhani omtsha we-coronavirus awuyi kuyeka, umkhuhlane omkhulu kunye nezinye iintsholongwane zobhubhane zivela, ezifuna ukuba senze ukhuseleko lobuqu olugqibeleleyo kwaye senze uxanduva olufanelekileyo kuluntu.Emva koko ekukhethweni kwezinto zokukhusela zomntu, kufuneka sibe yinto yokuqala yokukhetha iimaski, kwaye kukho iintlobo ezininzi zeemaski.Sazi njani malungaIimaski zeFFP2,iimaski ezilahlwayo, iimaski ezikhuselayo, iimaski zotyando, njl.Iimaski zonyango zesiko laseTshayina, iimaski zokhuselo lwezonyango zesiko, iifektri ze-ffp2 zemaski zabelana nawe ngolu lwazi lusisiseko.
UnokuZifuna ezi phambi kweodolo yakho
Ulwazi olusisiseko
Imaski yezonyango yenziwe ngumzimba wemaski kunye nebhanti loxinzelelo.Umzimba wemaski wohlulwe ngokwemigangatho yangaphakathi, ephakathi nangaphandle.Uluhlu lwangaphakathi luyimpahla ehambelana nolusu, umgca ophakathi ngumaleko wokucoca wedwa, kwaye umaleko wangaphandle ngumaleko okhethekileyo we-antibacterial.Le maski yonyango esebenza ngokufanelekileyo ine-hydrophobicity eyomeleleyo kunye nokungena komoya, kwaye inefuthe elibalulekileyo lokuhluza kwii-aerosols ezincinci ezithwala intsholongwane okanye amasuntswana othuli oluyingozi, kodwa ayinakuhluza ngokufanelekileyo i-PM10 kunye ne-PM2.5.Isiphumo sokuhluza ngokubanzi silungile, kwaye izinto ezisetyenzisiweyo azinatyhefu kwaye azinabungozi.Ukhululekile ukunxiba.
Uphawu
1. Ikhaphukhaphu, ikhululekile, ingenavumba, ingenayo i-fiber yeglasi, ingenalo i-skin, ingenamanzi.
2. Ikliphu yebhulorho yempumlo ethambileyo kwaye ekhululekile
3. Ukumelana nokuphefumla kufuneka kube kuncinci, kwaye kucocekile ukunxiba.I-aerosol, uthuli, ukutshisa, amathontsi enkungu, irhasi enetyhefu kunye nomphunga oyityhefu zibhengezwa sisihluzo ukuze zithintelwe ukuba zingaphefumlelwanga.
Ezinye iimpawu:
1. Ukusebenza kakuhle kokucoca: Ngaphantsi kweemeko ezichaziweyo, imveliso yokukhusela iya kucoca i-particulate matter emoyeni;
2. Ukusebenza kwe-Flame retardant: imveliso ekhuselayo ikhusela ukuvutha, ukuvutha kunye ne-flame retardant;
3. Ukubulala iintsholongwane: sebenzisa iindlela zomzimba okanye zekhemikhali ukubulala okanye ukususa iintsholongwane ze-pathogenic kwi-transmission medium ukuze zingabi yingozi;
4. Ukuvala inzala: bulala zonke iimicroorganisms kwindawo yosasazo ngeendlela zenyama okanye zekhemikhali ukuze zingabi ntsholongwane;
5. Inokufikelela kwisiphumo sothuli.
Ukuhlelwa
Kukho iintlobo ezininzi zeemaski zonyango.Iimaski eziqhelekileyo zonyango ziimaski ezingalukwanga ezilahlwayo, iimaski zegauze, kunye neemaski ezikhethekileyo zokulwa nentsholongwane.
1. Iimaski ezilahliweyo ezingalukwanga, ezineengqimba ezingaphezu kwezintathu, zinokuhlukanisa ibhaktheriya kunye nothuli, kwaye zilahlwa, zikhuselekile kwaye zithembekile, ngaphandle komngcipheko wosulelo lwesibini.
2. Iimaski zegauze lolona hlobo lusetyenziswa kakhulu lweemaski.Iimaski zeGauze zisetyenziswa ngokubanzi kwicandelo lokhathalelo lwezonyango kunye nophando lwesayensi.
3. Iimaski ze-Anti-virus zenziwa ikakhulu ngezinto ezikhethekileyo ezinoluhlu lokucoca phakathi.Ngokubanzi, umaleko wokucoca wenziwe ngekhabhoni esebenzayo okanye ilaphu elinyibilikayo.Inefuthe lokuvala inzala kunye nokuvala inzala.
2. Ngokweempawu zokusebenza kunye nobungakanani besicelo, iimaski zonyango zinokwahlulwa zibe: iimaski zokhuselo lwezonyango, iimaski zoqhaqho lwezonyango, kunye neemaski zonyango ngokubanzi.
1. Iimaski zokhuselo lwezonyango
Ngokuhambelana ne-GB19083-2003 "IiMfuno zobuGcisa kwiiMaski zoKhuseleko lwezoNyango", izikhombisi ezibalulekileyo zobugcisa ziquka ukusebenza kakuhle kokucoca i-particle non-oil kunye nokuchasana nokuhamba komoya:
(1) Ukusebenza kakuhle kokucoca: Ngaphantsi kwemeko yokuhamba komoya (85±2) L/min, ukusebenza kakuhle kokucoca i-aerosol ye-sodium chloride ene-aerodynamic median diameter (0.24±0.06) μm ayikho ngaphantsi kwe-95%, ehambelana nayo. N95 (okanye FFP2) nangaphezulu.
(2) Ukuxhatshazwa kwe-inhalation: Ngaphantsi kweemeko zokuhamba ngasentla, ukuchasana kwe-inhalation akudluli i-343.2Pa (35mmH2O).
2. Iimaski zotyando lwezonyango
Ngokuhambelana ne-YY 0469-2004 "IiMfuno zobuGcisa kwiiMaski zoNyango lwezoNyango", izikhombisi ezibalulekileyo zobugcisa ziquka ukusebenza kakuhle kokucoca, ukucocwa kwebhaktheriya kunye nokuchasana nokuphefumla:
(1) Ukusebenza kakuhle kokucoca: phantsi kwemeko yokuhamba komoya (30 ± 2) L / min, ukusebenza kakuhle kwe-filtration ye-sodium chloride aerosol ene-aerodynamic median diameter (0.24± 0.06) μm ayikho ngaphantsi kwe-30%;
(2) Ukusebenza kakuhle kwe-bacterial filtration: phantsi kweemeko ezichaziweyo, ukusebenza kakuhle kokucoca kwe-Staphylococcus aureus aerosols kunye ne-avareji ye-particle ububanzi (3± 0.3) μm ayikho ngaphantsi kwe-95%;
(3) Ukuchasana nokuphefumula: Ngaphantsi kwemeko yokusebenza kakuhle kokucoca kunye nesantya sokuhamba, ukuchasana kokuphefumula akudluli i-49Pa, kwaye ukuchasana kokuphefumula akudluli i-29.4Pa.
3. Iimaski zonyango eziqhelekileyo
Ngokuhambelana nemigangatho yemveliso ebhalisiweyo ebhalisiweyo (YZB), ngokubanzi ukunqongophala kweemfuno zobuchule bokuhluza amasuntswana kunye neebhaktheriya, okanye iimfuno zokusefa okusebenzayo kwamasuntswana kunye neebhaktheriya ziphantsi kuneemaski zoqhaqho lwezonyango kunye neemaski zokhuselo lwezonyango.
