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

Ungakwazi yini umehluko phakathi kwezinhlobo ezahlukene zamaski wezokwelapha?Ingabe uyazi ngempela ngazo zonke lezi zimaski, njengamamaski avamile wezokwelapha, imaski yokuhlinzwa yezokwelapha, imaski yokuzivikela yezokwelapha, imaski engu-N95, imaski ye-KN95 ...?Uma uzizwa udidekile, lesi sihloko sizokuhambisa kulawa maski ahlukene.

Izinhlobo zamamaski ezokwelapha

Amamaski ezokwelapha akhiwe ngezindwangu zezingqimba ezintathu.Isendlalelo sangaphakathi ngokuvamile singeyona i-gauze engalukiwe noma evamile;ungqimba oluphakathi ngokuvamile luwungqimba lwesihlungi sokuhlukanisa olwenziwa nge-ultra-fine polypropylene fiber meltblown material;ungqimba lwangaphandle ngokuvamile luwungqimba olukhethekile olulwa namagciwane olwenziwa ngezinto ezingalukiwe noma ezincibilikisiwe ze-ultra-thin polypropylene.

Kafushane, kunezinhlobo ezintathu zamamaski ezokwelapha:

1.Imaski yezokwelapha evamile

Imaski yezokwelapha evamile, eyaziwa nangokuthi imaski elahlayo yezokwelapha, isetshenziselwa ukuvimba umlomo namakhala ngezinga eliphansi lokuvikela.Ifanele imisebenzi yokunakekelwa kwezempilo evamile, njengokuthuthwa kwendle nokuhlanza, ukukhipha uketshezi, ukuhlanza ilineni, njll., noma ukuvimbela noma ukuvikela izinhlayiya, impova, njll. ngaphandle kwama-microorganisms e-pathogenic.

2.Imaski Yokuhlinzwa Yokwelapha

Imaski yokuhlinzwa yezokwelapha ifanele ukuvikelwa okuyisisekelo kwabasebenzi bezokwelapha noma abahlobene kanye nokumisa ukusabalala kwegazi, uketshezi lomzimba nokuchaphaza phakathi nokuhlinzwa okubuhlungu ngezinga elimaphakathi lokuvikela kanye nokuvikela ukuphefumula okuthile.

3.Imaski yokuvikela yezokwelapha

Imaski yokuzivikela yezokwelapha isetshenziselwa ukuvikela abasebenzi bezokwelapha kanye nabahlobene ngokumelene nezifo zokuphefumula emoyeni futhi iwuhlobo oluthile lwedivayisi yokuzivikela, ekwazi ukuzibamba kanye nokuhlunga ngezinga eliphezulu lokuvikela elifaneleka ngokukhethekile ukugqokwa lapho uthintana neziguli izifo zokuphefumula ezithwalwa ngamaconsi emoyeni noma ezivalekayo phakathi nemisebenzi yazo yokwelapha.Ihlunga izinhlayiya ezihamba emoyeni futhi ivimbe amaconsi, igazi, uketshezi lomzimba kanye nama-microdroplets of secretions njengomkhiqizo olahlwayo.

Ukuhlukaniswa kwamazinga asebenzayo

1. Izinga elisebenzayo lokukhethwa kwamamaski alahlwayo yi-YY/T0969-2013Amamaski ezokwelapha asetshenziswa kanye.Amamaski ezokwelapha aklanywa kakhulu futhi akhiqizwa amabhizinisi, ngokuvamile angenakukuqinisekisa ukuhlungwa kwama-microorganisms e-pathogenic nothuli, futhi umphumela wangempela wokuvikela awugculisi kakhulu.

2. Izinga elisebenzayo lokukhethwa kwamamaski alahlwayo yi-YY0469-2011imaski yokuhlinzwa yezokwelapha.Imaski yokuhlinzwa yezokwelapha inokuhlunga okungaphezulu kwama-95% kumagciwane kanye nangaphezulu kuka-30% ezinhlayiya ezingezona amafutha, futhi iningi lawo liwunxande ekwakhiweni futhi awalingani kahle ebusweni njengamamaski okuvikela ezokwelapha.Amamaski ajwayelekile okuhlinzwa kwezokwelapha yimaski eyibhande, imaski ye-ear loop, njll.

Izinga elisebenzayo lokukhethwa kwamamaski okuvikela ezokwelapha yi-GB19803-2010izidingo zobuchwepheshe zamamaski okuvikela ezokwelashwa.Amamaski okuvikela ezokwelapha ahlukaniswe ngamaleveli amathathu, ngalinye lisebenza kahle ngokuhlunga okungama-95%, 99% kanye nama-99.97% ezinhlayiya ezingenawo amafutha.Omaskandi be-KN95/N95 basebenza kahle ngokucwenga okungaphezu kuka-95% ezinhlayiya ezingenawo amafutha, futhi imaski yokuvikela yezokwelapha evamile ingahlangabezana nezidingo ze-“N95/KN95” ezingeni lokuqala.

Nokho, kufanele kuqashelwe ukuthi:

Amamaski e-KN95 asuselwa ku-GB2626-2006 yaseShayina ejwayelekileImikhiqizo Yokuvikela Ukuphefumula Ezizimuncayo Isiphefumulo Esilwa Nezinhlayiyana Ezihlungiwe futhi ihlukaniswe ngochungechunge lwe-KN ne-KP, ngochungechunge lwe-KN luvimbe i-particle non-oilly particulate kanye nochungechunge lwe-KP luvimba kokubili okuyizinhlayiyana ezinamafutha nezingezona amafutha.Kamuva ngoJulayi 2020, kwasetshenziswa indinganiso entsha ye-GB2626-2019, okungeza ukusebenza kwezinkomba zokuhlola.

Imaski engu-N95 umqondo ohlongozwa yiNational Institute for Occupational Safety and Health (NIOSH) kumthethonqubo wombuso wase-US 42 CFR Ingxenye 84, okuhlanganisa i-N, R, P emithathu uchungechunge.Uchungechunge lwe-N luyizinto zokuvikela ukuphefumula (okuhlanganisa namamaski) ezingavimba izinhlayiya ezingezona uwoyela.Kodwa-ke, i-N95 ayikwazi ukusungulwa ohlelweni olujwayelekile lwasekhaya.Ngakho-ke, izinga elisebenzayo yi-GB2626-2006 nesitifiketi se-NIOSH.

Ngokuvamile, ukusebenza kahle kokuhlunga kwezinhlayiyana zamamaski e-KN95 kanye ne-N95 kuyafana, kodwa amazinga abo okuthola izitifiketi nokuhlolwa kokusebenza kwehlukile.Kokubili imaski ye-KN95 ne-N95 ihlukaniswa njengeyezokwelapha futhi engeyona eyezokwelapha.Izinga lamamaski ezokwelapha linento eyengeziwe- “ukumelana nomswakama ongaphezulu”, engavikela ekuchaphazeni uketshezi lomzimba.Iqinile uma kuqhathaniswa.

Ngaphezu kwalokho, indinganiso yaseShayina i-GB2626-2006/2019 isho indinganiso yemaski ye-KN95 evamile kanye nezinga lezokwelapha le-KN95 yi-GB19083-2010.Abantu abajwayelekile kanye nabasebenzi bezokunakekelwa kwempilo abangavezwanga isifutho soketshezi esinengcindezi ephezulu bangasebenzisa imaski ejwayelekile ye-KN95.

Imaski yebhande lekhanda le-KN95/N95 inophawu olungcono, olungagcini nje ukuvikela indlela yokuphefumula kumabhaktheriya nothuli, kodwa futhi ivumela ukuthi kufakwe imichilo yesipontshi, okwenza kube lula ukugqoka.Amabhakede alungisekayo ezindlebeni zamaski angadambisa ngempumelelo ubuhlungu bezindlebe obubangelwa ukugqoka imaski isikhathi eside.

Ukuhlukaniswa kwemishini yokukhiqiza

Amamaski ezokwelapha ngokuvamile awanayo inyumbazane.Idinga ukukhiqizwa okudingekayo esitshalweni esihlanzekile esiyinyumba esiyi-100,000 esinamasistimu okuhlanza umoya kanye nezinhlelo zamanzi ahlanzekile.Ngaphandle kwalokho, ukukhiqizwa komamaski bezokwelapha kuqedwa ngemuva kokuthi kukhethiwe izinto zokusetshenziswa futhi imaski isibunjiwe, yacindezelwa, yasikwa, izihibe ezindlebeni zashiselwa, intambo yekhala yashiselwa, yahlanganiswa, yafakwa inzalo futhi yahlaziywa (i-EO sterilization).

Ukuze kuzuzwe inqubo yokukhiqiza engenhla, imishini yokukhiqiza ezenzakalelayo ngokugcwele noma i-semi-automatic iyadingeka.Amamaski ezokwelapha aqediwe angakhiqizwa umshini owodwa ozenzakalelayo okwazi ukuqedela yonke inqubo yokukhiqiza, kusukela ekuphakeleni izinto ezingavuthiwe kuya ekupakisheni.Ngaphezu kwalokho, umshini we-mask oyisicaba ungakhiwa umshini owodwa wokwenza imaski womzimba omkhulu kanye nomshini wokushisela i-ear loop welding emi-2 noma emi-3, ongathola ukukhiqizwa okusebenza kahle kakhulu.

I-Henyyao igcwele i-othomathikhi egcwele i-high speed high mask masks umshini kanye nomshini wokugoqa isivinini esikhulu, ofakwe ukutholwa kwe-photoelectric kanye nomsebenzi wokubala okuzenzakalelayo, izihibe zendlebe ezishisela ngokuzenzakalelayo nocingo lwekhala, i-welding kanye nemiphetho yokusika, eqinisekisa ubuhle nezinga eliphezulu lemikhiqizo.Ingase futhi ifakwe idivayisi elungisa ukuchezuka kanye nedivayisi yokunamathisela isipontshi, okuvumela imikhiqizo ukuthi ihlangabezane nezidingo eziningi zemakethe;Umshini uyakwazi ukukhiqiza imaski ye-ear loop, imaski yebhande lekhanda, imaski yebhande eguquguqukayo, okwenza imikhiqizo ibe nokuncintisana kakhulu.

Ukuze kwanelise izidingo zokukhiqiza ezihlukene, umshini womamaski we-Hengyao ungapakisha ngokuzenzakalelayo imikhiqizo eqediwe, elula futhi ehlanzekile;imaski eyisicaba ingahlonyiswa ngomsebenzi wokufaka imaski ngokuzenzakalelayo emabhokisini.Umshini owodwa wemaski womzimba oxhumene nomshini wokushisela i-ear loop welding wenza ukukhiqizwa kusebenze kahle kakhulu.Umshini wamaski we-Hengyao wonke ungabona ukukhiqizwa okuzenzakalelayo kwamamaski ebhande, imaski ye-ear loop flat (egoqayo), imaski yebhande lekhanda, imaski yefilimu yokuvikela kanye nezinye izifihla-buso zamaqembu ahlukene okusetshenziswa nezimo, futhi zibe nemakethe ebanzi.
