Njengamanje, impi ezweni lonke yokulwa nenyumoniya ebangelwa i-coronavirus yenoveli isiqalile. Njenge "ndlela yokuqala yokuvikela" yokuvikela inhlanzeko yomuntu siqu, kubaluleke kakhulu ukugqoka izifihla-buso ezihlangabezana namazinga okuvikela ubhadane. Ukusuka ku-N95, i-KN95 kuya kumaski wokuhlinza wezokwelapha, abantu abavamile bangaba nezindawo ezingaboni lapho bekhetha amaski. Lapha sifingqa amaphuzu wolwazi enkambini ejwayelekile ukukusiza uqonde umqondo ojwayelekile wamamaski.
Ayini amazinga wamamaski?
Njengamanje, izindinganiso eziyinhloko zaseChina zemaski zifaka i-GB 2626-2006 “Imishini yokuphefumula yokuzivikela eyisihlungi sohlobo lokuphefumula”, GB 19083-2010 “Izidingo zobuchwepheshe zamaski okuvikela ezokwelapha”, YY 0469-2004 “Izidingo zobuchwepheshe kwezokwelapha izifihla-buso zokuhlinza ”, GB / T 32610-2016“ Imininingwane Yezobuchwepheshe Yamamaski Wokuzivikela Wansuku zonke ”, njll., ehlanganisa ukuvikelwa kwabasebenzi, ukuvikelwa kwezokwelapha, ukuvikelwa komphakathi neminye imikhakha.

I-GB 2626-2006 "Insiza Yokuzivikela Yokuphefumula Yokuhlunga I-anti-Particulate Respirator" yamenyezelwa yi-General Administration yangaphambili ye-Quality Supervision, Inspection and Quarantine kanye ne-National Standardization Management Committee. Kuyindinganiso ephoqelekile yombhalo ophelele futhi yaqala ukusetshenziswa ngoDisemba 1, 2006. Izinto zokuvikela ezibekwe kuzinga zifaka phakathi zonke izinhlobo zezinto eziyizinhlayiyana, kufaka phakathi uthuli, intuthu, inkungu kanye nezilwanyana ezincane. Iphinde ichaze ukukhiqizwa nokucaciswa kobuchwepheshe bemishini yokuphefumula yokuphefumula, nezinto, ukwakheka, ukubukeka, ukusebenza, kanye nokusebenza kahle kokuhlunga kwamamaski othuli (isilinganiso sokumelana nothuli), ukumelana nokuphefumula, izindlela zokuhlola, ukuhlonza umkhiqizo, ukupakisha, njll. izidingo.

I-GB 19083-2010 "Izidingo Zobuchwepheshe Zamamaski Avikelayo Ezokwelapha" yamenyezelwa yi-General Administration yangaphambili ye-Quality Supervision, Inspection and Quarantine kanye ne-National Standardization Management Committee, futhi yasetshenziswa ngo-Agasti 1, 2011. Leli zinga licacisa izidingo zobuchwepheshe, ukuhlolwa izindlela, izimpawu nemiyalo yokusetshenziswa kwamamaski okuvikela ezokwelapha, kanye nokupakisha, ukuhambisa kanye nokugcina. Ifanele ukusetshenziswa ezindaweni zokusebenza zezokwelapha ukuhlunga izinhlayiya ezisemoyeni nokuvimba amaconsi, igazi, uketshezi lomzimba, uketshezi, njll. I-4.10 yezinga inconyiwe, futhi konke okunye kuphoqelekile.

I-YY 0469-2004 "Izidingo Zobuchwepheshe Zamamaski Wokuhlinzwa Kwezokwelapha" yamenyezelwa yi-State Food and Drug Administration njengezinga lomkhakha wezemithi futhi yasetshenziswa ngoJanuwari 1, 2005. Leli zinga licacisa izidingo zobuchwepheshe, izindlela zokuhlola, izimpawu nemiyalo ukusetshenziswa, ukupakisha, ukuthuthwa kanye nokugcinwa kwamamaski okuhlinzwa wezokwelapha. Izinga libeka ukuthi ukusebenza kahle kwamagciwane kokuhlunga akumele kube ngaphansi kwama-95%.
I-GB / T 32610-2016 “Imininingwane Yezobuchwepheshe Yamamaski Avikela Nsuku Zonke” ikhishwe yi-General Administration yangaphambili ye-Quality Supervision, Inspection and Quarantine kanye ne-National Standardization Management Committee. Kuyizindinganiso zokuqala zikazwelonke zezimaski zokuvikela umphakathi futhi zaqaliswa ngoNovemba 1, 2016. Izinga lifaka izidingo zemaskhi, izidingo zesakhiwo, izidingo zokuhlonza ilebula, izidingo zokubukeka, njll. Izinkomba eziyinhloko zifaka izinkomba zokusebenza, ukusebenza kahle kokuhlunga izinto , izinkomba zokuphefumula nezikhuthazayo, nezinkomba zokunamathela. Izinga lidinga ukuthi izifihla-buso kufanele zikwazi ukuvikela umlomo nokukhala ngokuphepha nangokuqinile, futhi akumele kube khona amakhona abukhali nemiphetho engathintwa. Inemithetho eningiliziwe yezinto ezingadala ingozi emizimbeni yabantu efana ne-formaldehyde, idayi, nezilwanyana ezincane ukuqinisekisa ukuthi umphakathi uyakwazi ukuzigqoka. Ukuphepha lapho ugqoke izifihla-buso zokuzivikela.

Yimaphi amamaski avamile?

Manje amaski ashiwo njalo afaka phakathi i-KN95, i-N95, imaski yokuhlinzwa yezokwelapha nokunye.

Esokuqala buso beKN95. Ngokwesigaba se-standard ejwayelekile kazwelonke i-GB2626-2006 "Imishini yokuphefumula yokuzivikela yokuzicwenga yona-uhlobo lwe-anti-particulate respirator", imaski ihlukaniswe yaba yi-KN ne-KP ngokwezinga lokusebenza kahle kwento yokuhlunga. Uhlobo lwe-KP lufanele ukuhlunga izinhlayiya ezinamafutha, nohlobo lwe-KN lufanele ukuhlunga izinhlayiya ezingekho oily. Phakathi kwazo, lapho kutholakala imaski ye-KN95 enezinhlayiya ze-sodium chloride, ukusebenza kwayo kokuhlunga kufanele kube kukhulu noma kulingane no-95%, okungukuthi, ukusebenza ngokusefa kwezinhlayiya ezingekho uwoyela ngaphezu kuka-0.075 microns kukhulu noma kulingana no-95%.

Isifihla-buso se-N95 singesinye sezimaski eziyisishiyagalolunye zokuvikela eziqinisekiswe yi-NIOSH (National Institute of Occupational Safety and Health). “N” kusho ukungazweli kuwoyela. “95 ″ kusho ukuthi lapho kuvezwa inani elithile lezinhlayiya zokuhlola ezikhethekile, ukuminyana kwezinhlayiya ngaphakathi kwemaski kungaphansi kwama-95% ngaphansana kwenhlayiya yezinhlayiya engaphandle kwemaski.

Ingabe kukhona imaski ku- "Pin Word Mark"?

NgoNovemba 9, 2018, iT / ZZB 0739-2018 "Civilian Oil Fume Respirator" eyakhiwe yiJiande Chaomei Daily Chemical Co., Ltd. ikhishwe yiZhejiang Brand Construction Association.
Izinkomba zezobuchwepheshe ezisemqoka zaleli zinga zisethwe ngokuya ngezici zokusebenza komkhiqizo, bhekisa ku-GB / T 32610-2016 "Imininingwane Yezobuchwepheshe Yamamaski Wokuvikela Wansuku zonke", kuhlanganiswe ne-GB2626-2006 "Self-priming Filtered Particle Respirators", GB19083-2010 " Amazinga Wokuvikelwa Kwezokwelapha afana neMaski, i-US NIOSH “Masks Avikelayo” kanye ne-European Union EN149 “Masks Avikelayo” asetshenziswa kakhulu ezindaweni zokuvikela ukuphefumula lapho exhunyaniswa nokugxila okuphezulu okunamafutha (njengamakhishi nezindawo zebhayisikili). Izinga lichaza ukuthi ukusebenza kahle kokuhlunga izinhlayiya ezinamafutha kungaphezu kwama-90%, kanti izinkomba ezisele zisekelwe ekuhlangabezaneni nezindinganiso ezisezingeni elingu-A lamamaski omphakathi kanye namazinga ezimaski zokuvikela abasebenzi ezingafakwa uwoyela eYurophu nase-United States, futhi beka phambili izidingo eziphakeme zokuvuza, ukumelana nokuphefumula, izinkomba zamagciwane, ne-pH. Kungezwe imfuneko yenkomba yokubambezeleka yokubambezeleka ebambezelekile.

Kunamaski amaningi avikelayo anezinhlayiya ze-KN90 \ KN95 ebangeni elingewona uwoyela emakethe. Izimaski zokuzivikela zohlobo lwe-KP zivame ukuba nokumelana okuphezulu kakhulu, futhi ubuhle bazo nokunethezeka kwazo zombili izindinganiso zemaski zokuvikela ezimbonini, okunzima ukuhlangabezana nezidingo zabantu zansuku zonke.

Ukwakhiwa kwamazinga ezimaski zemfucumfucu kahulumeni kudlale indima enhle empilweni yabantu. Kwabaningi babasebenzi basekhishini, ukwakheka kwaleli zinga kusiza ukukhetha imishini efanelekile yokuvikela indawo yabo yokusebenza.

Bese kuba khona izifihla-buso zokuhlinza zezokwelapha. Ngokwencazelo ye-YY 0469-2004 "Izidingo Zobuchwepheshe Zamamaski Wokuhlinzwa Kwezokwelapha", izifihla-buso zezokwelapha "zigqokwa ngabasebenzi bezokwelapha endaweni yokusebenza, ukuhlinzeka ngokuvikelwa kweziguli ezelashwa kanye nabasebenzi bezokwelapha abenza imisebenzi engafuneki, nokuvikela Izimaski zokuhlinza zezokwelapha ezisatshalaliswa yigazi, uketshezi lomzimba nokuchaphaza yimifino egqokwa abasebenzi bezokwelapha emsebenzini. ” Lolu hlobo lwesifihla-buso luyasetshenziswa ezindaweni zezokwelapha ezifana nemitholampilo yabangalaliswa ngaphandle, emalabhorethri, nasemakamelweni okuhlinza, futhi ihlukaniswe ungqimba olungangenisi manzi, ulwelwesi lokuhlunga, nolwelwesi lokududuza kusuka ngaphandle kuye ngaphakathi.

Ukukhethwa kwesayensi kwamamaski

Ochwepheshe bathi ngaphezu kokuhlinzeka ngokuvikelwa okusebenzayo, ukugqoka izifihla-buso kumele kubhekele nokunethezeka komuntu okugqokile hhayi ukuletha imiphumela emibi njengezingozi zebhayoloji. Ngokuvamile, ukuphakama kokuvikela imaski kuyanda, umthelela omkhulu ekusebenzeni kwenduduzo. Lapho abantu begqoka imaski futhi behogela, imaski inokumelana okuthile nomoya ogelezayo. Lapho ukumelana nokuhogela kukhulu kakhulu, abanye abantu bazozizwa benesiyezi, ukuqina kwesifuba nokunye ukungakhululeki.

Abantu abehlukene banezimboni nemizimba eyahlukene, ngakho-ke banezidingo ezahlukahlukene zokubekwa uphawu, ukuvikelwa, ukunethezeka, nokuzivumelanisa nezimo kwamamaski. Abanye abantu abakhethekile, njengezingane, asebekhulile, nabantu abanezifo zokuphefumula nezifo zenhliziyo, kufanele bakhethe ngokucophelela uhlobo lobuso. Ngesisekelo sokuqinisekisa ukuphepha, gwema izingozi ezinjenge-hypoxia nesiyezi lapho uzigqoka isikhathi eside.

Ekugcineni, khumbuza wonke umuntu ukuthi noma ngabe uluphi uhlobo lobuso bamaski, kufanele luphathwe kahle ngemuva kokusetshenziswa ukugwema ukuba ngumthombo omusha wokutheleleka. Imvamisa lungisa ezinye izimaski ezimbalwa bese uzifaka esikhundleni sazo ngesikhathi sokwakha umugqa wokuqala wokuvikela ukuvikelwa kwezempilo. Nginifisela impilo enhle nonke!

Njengezinkampani
