Can you really tell the difference between different types of medical masks?

Ngaba ngokwenene unomahluko phakathi kweentlobo ezahlukeneyo zeemaski zonyango?Ngaba uyazi ngenene ngazo zonke ezi maski, njengeemaski eziqhelekileyo zonyango, iimaski zoqhaqho lwezonyango, iimaski zokhuseleko lwezonyango, iimaski ezi-N95, iimaski ze-KN95 ...?Ukuba uziva ubhidekile, eli nqaku liza kukusa kwezi maski zahlukeneyo.

Iintlobo zeemaski zonyango

Iimaski zonyango zenziwe ngamalaphu amathathu.Umaleko wangaphakathi ngokuqhelekileyo awulukwanga okanye awulukiweyo ucoceko oluqhelekileyo;umaleko ophakathi ngokuqhelekileyo ngumaleko wesihluzo esizimeleyo esenziwe nge-ultra-fine polypropylene fiber meltblown material;umaleko wangaphandle ngokuqhelekileyo ngumaleko okhethekileyo ochasene neentsholongwane owenziwe ngezinto ezingalukwanga okanye ezibhityileyo zepolypropylene ezinyibilikayo.

Isishwankathelo, kukho iintlobo ezintathu zeemaski zonyango:

1.Imaski yezonyango rhoqo

Iimaski eziqhelekileyo zonyango, ezaziwa ngokuba ziimaski ezilahlwayo zonyango, zisetyenziselwa ukuvala umlomo kunye nokutshiza kweempumlo ngelona nqanaba lisezantsi lokhuseleko.Ifanelekile kwimisebenzi yokunakekelwa kwezempilo jikelele, njengokucoceka kunye nokucoca, ukukhupha i-liquid, ukucocwa kwelinen, njl., okanye umqobo okanye ukukhuselwa kwamaqhekeza, i-pollen, njl. Ngaphandle kwe-microorganisms ye-pathogenic.

2.Medical Utyando imaski

Imaski yotyando lwezonyango ilungele ukhuseleko olusisiseko lwabasebenzi bezonyango okanye abanxulumeneyo kunye nokumisa ukusasazeka kwegazi, ulwelo lomzimba kunye nokutshiza ngexesha lotyando olothusayo olunomgangatho ophakathi wokhuseleko kunye nokhuseleko lokuphefumla.

3.Imaski ekhuselayo yonyango

Imaski yokhuselo lwezonyango isetyenziselwa ukhuseleko lwabasebenzi bezonyango kunye nabasebenzi abanxulumeneyo ngokuchasene nosulelo lokuphefumla ngomoya kwaye luhlobo olungenamoya, oluzifunxayo kunye nokucoca isixhobo sokhuselo lwezonyango esinomgangatho ophezulu wokhuselo olufaneleke ngakumbi ukunxitywa xa unxibelelana nezigulana ezineentsholongwane zentliziyo. Usulelo lokuphefumla oluphuma emoyeni okanye oluvale amathontsi ngexesha lemisebenzi yonyango.Ihluza amasuntswana omoya kwaye ivalele amathontsi, igazi, ulwelo lomzimba kunye ne-microdroplets yemfihlo njengemveliso elahlayo.

Ukuhlelwa kwemigangatho esebenzayo

1. Umgangatho osebenzayo wokukhethwa kweemaski ezilahlwayo zonyango ngu-YY/T0969-2013Iimaski zonyango ezisetyenziswa kanye.Iimaski zonyango ubukhulu becala ziyilwe kwaye zenziwe ngamashishini, angenakuqinisekisa ngokubanzi ukuhluzwa kwe-microorganisms ze-pathogenic kunye nothuli, kwaye isiphumo soqobo sokukhusela ayanelisi kakhulu.

2. Umgangatho osebenzayo wokukhethwa kweemaski ezilahlwayo zonyango ngu-YY0469-2011iimaski zotyando lwezonyango.Iimaski zotyando zonyango zisebenza ngokusulungekileyo okungaphezulu kwe-95% yeebhaktheriya kwaye ngaphezulu kwe-30% yamasuntswana angeyooli, kwaye uninzi lwazo luxande kuyilo kwaye alulungelelanisi ngokuqinileyo ebusweni njengemaski zokhuseleko lwezonyango.Iimaski eziqhelekileyo zoqhaqho lwezonyango ziimaski zemitya, imaski ye-ear loop, njl.

Umgangatho osebenzayo wokukhethwa kweemaski zokhuselo lwezonyango yi-GB19803-2010iimfuno zobugcisa kwiimaski zokhuselo lwezonyango.Iimaski zokhuselo lwezonyango zahlulwe zaba ngamanqanaba amathathu, ngalinye linokucoca okusebenzayo kwe-95%, 99% kunye ne-99.97% yamasuntswana angeyo-oyile.Iimaski ze-KN95/N95 zisebenza ngokusulungekileyo ngaphezulu kwe-95% yamasuntswana angeyo-oyile, kwaye iimaski zokhuselo lwezonyango ngokubanzi zinokuhlangabezana neemfuno ze- "N95/KN95" kwinqanaba lokuqala.

Nangona kunjalo, kufuneka kuqatshelwe ukuba:

Iimaski ze-KN95 zisekwe kumgangatho waseTshayina we-GB2626-2006IiMveliso zoKhuseleko lokuphefumla ezizifunxayo ngokuZifunxayo eziHluliweyo ezichasene neParticle kwaye zahlulwe zibe KN kunye KP series, kunye KN series evalela non-oyile particulate into kunye KP series evalela zombini ezinamafutha kunye non-oyile masuntswana.Kamva ngoJulayi 2020, umgangatho omtsha we-GB2626-2019 waphunyezwa, ukongeza ukusebenza kwizalathi zovavanyo.

I-mask ye-N95 ingcamango ecetywayo yiNational Institute for Occupational Safety and Health (NIOSH) kwi-US federal regulation 42 CFR Part 84, kuquka i-N, R, P ezintathu series.Uchungechunge lwe-N zixhobo zokukhusela ukuphefumla (kubandakanya iimaski) ezinokuthintela amasuntswana angeyooli.Nangona kunjalo, i-N95 ayinakusekwa kwinkqubo efanelekileyo yasekhaya.Ke ngoko, umgangatho osebenzayo yi-GB2626-2006 kunye nesatifikethi se-NIOSH.

Ngokubanzi, ukusebenza kakuhle kokucoca imaski ye-KN95 kunye ne-N95 iyafana, kodwa imigangatho yabo yokuqinisekisa kunye novavanyo lokusebenza yahlukile.Zombini iimaski ze-KN95 kunye ne-N95 zihlelwa njengezonyango kunye nezingezizo ezonyango.Umgangatho weemaski zonyango unento eyongezelelweyo- "ukumelana nokufuma okungaphezulu", enokukhusela ekutshizeni ulwelo lomzimba.Ingqongqo ngakumbi.

Ukongeza, umgangatho waseTshayina we-GB2626-2006/2019 ubhekisa kumgangatho oqhelekileyo wemaski we-KN95 kunye nomgangatho we-KN95 wezonyango yi-GB19083-2010.Abantu abaqhelekileyo kunye nabasebenzi bezempilo abangavezwanga kwisitshizi solwelo olunoxinzelelo oluphezulu banokusebenzisa iimaski eziqhelekileyo ze-KN95.

Imaski ye-KN95 / N95 yentloko yentambo inesitywina esingcono, esingakhuseli nje kuphela indlela yokuphefumula kwibhaktheriya kunye nothuli, kodwa ivumela ukuba imicu yesipontshi iqhotyoshelwe, iyenze ibe lula ukuyinxiba.Izibophelelo ezilungelelanisiweyo kwimitya yeendlebe zeemaski zinokukhulula ngokufanelekileyo iintlungu zendlebe ezibangelwa kukunxitywa kweemaski ixesha elide.

Ukuhlelwa koomatshini bokuvelisa

Iimaski zonyango zihlala zinyumba.Ifuna ukuveliswa kufuna kwiklasi ye-100,000 yesityalo esicocekileyo esicocekileyo esineenkqubo zokucoca umoya kunye neenkqubo zamanzi ahlambulukileyo.Ngaphandle koko, ukuveliswa kweemaski zonyango kugqitywe emva kokuba kuchongwe izixhobo ezikrwada kwaye imaski ibunjiwe, yacinezelwa, yaculwa, indlebe ezirhintyela zidityanisiwe, intambo yempumlo yadityaniswa, yapakishwa, yafakwa inzalo kwaye yahlalutywa (EO sterilization).

Ukuze kuphunyezwe le nkqubo yokuvelisa ingentla, kufuneka izixhobo zokuvelisa ezizenzekelayo ngokupheleleyo okanye ezizezinye.Iimaski ezigqityiweyo zonyango zinokuveliswa ngoomatshini abazenzekela ngokupheleleyo abakwaziyo ukugqiba yonke inkqubo yemveliso, ukusuka ekondleni izinto ezikrwada ukuya ekupakishweni.Ukongeza, umatshini wemaski osicaba unokuqulunqwa ngumatshini omnye wokwenza imaski yomzimba kunye nomatshini wokuwelda i-ear loop emi-2 okanye emi-3, onokufumana imveliso ephezulu esebenzayo.

I-Henyyao igcwele i-automatic high speed high-speed imaski umatshini kunye nesantya esiphezulu somatshini wokusonga imaski, exhotyiswe ngokuchongwa kwe-photoelectric kunye nomsebenzi wokubala ngokuzenzekelayo, i-welding ye-ear loops kunye nocingo lwempumlo, i-welding kunye nemiphetho yokusika, eqinisekisa ubuhle kunye nomgangatho ophezulu weemveliso.Kananjalo inokuxhotyiswa ngesixhobo sokutenxa ukulungisa kunye nesixhobo sokuncamathelisa isipontshi, sivumela iimveliso ukuba zihlangabezane noluhlu olubanzi lweemfuno zemarike;Umatshini uyakwazi ukuvelisa iimaski ze-ear loop, imaski yentambo yentloko, iimaski ezilungelelanisiweyo, ukwenza iimveliso zikhuphisane ngakumbi.

Ukwanelisa iimfuno ezahlukeneyo zemveliso, umatshini weemaski zeHengyao unokupakisha ngokuzenzekelayo iimveliso ezigqityiweyo, ezifanelekileyo kwaye zicocekile;imaski ecaba inokuxhotyiswa ngomsebenzi wokubeka iimaski ngokuzenzekelayo kwiibhokisi.Umatshini omnye wemaski womzimba odityaniswe nomatshini wokuwelda we-ear loop wenza imveliso isebenze ngakumbi.Umatshini weemaski zeHengyao bonke banokuqonda ukuveliswa okuzenzekelayo kweemaski zemitya, indlebe ye-loop flat (ukusonga) imaski, iimaski zemitya yentloko, imaski yefilimu ekhuselayo kunye nezinye iimaski zamaqela osetyenziso ahlukeneyo kunye neemeko, kwaye unentengiso ebanzi.
