Iindidi zeemaski ikakhulu zibandakanya iimaski eziqhelekileyo zegauze, iimaski zonyango (ezidla ngokulahlwa), iimaski zothuli lwamashishini (ezifana neemaski ze-KN95 / N95), iimaski zokhuselo lwemihla ngemihla kunye neemaski ezikhuselayo (zikhusele kumsi weoyile, iibhaktheriya, uthuli, njl. njl.).Xa kuthelekiswa nezinye iintlobo zeemaski, iimaski zonyango zineemfuno eziphezulu zobugcisa, kwaye zinokuveliswa kuphela emva kokufumana isatifikethi esifanelekileyo sobhaliso lwesixhobo sonyango.Kubantu abaqhelekileyo abahlala ekhaya okanye kwimisebenzi yangaphandle, ukukhetha iimaski zonyango ezilahlayo okanye iimaski eziqhelekileyo zokukhusela zinokuhlangabezana neemfuno zemihla ngemihla zokukhusela ubhubhane.
Ngokwemilo, iimaski zinokwahlulwa zibe luhlobo olusicaba, uhlobo lokusonga kunye nodidi lwekomityi.Imaski yobuso obucaba kulula ukuyiphatha, kodwa ukuqina akubikho.Imaski esongwayo ikulungele ukuphatha.Indawo yokuphefumla emile okwekomityi inkulu, kodwa ayifanelekanga ukuyiphatha.
Inokwahlulwa ibe ngamacandelo amathathu ngokwendlela yokunxiba.Uhlobo lokugqoka intloko lufanelekile kubasebenzi beeworkshop abanxiba ixesha elide, eliyinkathazo.Ukunxitywa kweendlebe kulula ukunxiba kunye nokukhulula rhoqo.Intamo enxibe uhlobo isebenzisa iigwegwe ze-S kunye nezinye izihlanganisi zezinto ezithambileyo.Ibhande lendlebe elidibanisayo liguqulwa libe luhlobo lwebhanti yentamo, olufanelekileyo ukugqoka ixesha elide, kwaye lulungele ngakumbi kubasebenzi beworkshop abanxibe izigqoko zokhuseleko okanye iimpahla zokukhusela.
E-China, ngokokuhlelwa kwezinto ezisetyenzisiweyo, zinokwahlulwa zibe ziindidi ezintlanu:
1. Iimaski zeGauze: Iimaski zeGauze zisasetyenziswa kwezinye iiworkshops, kodwa iimfuno zomgangatho we-GB19084-2003 ziphantsi kakhulu.Ayihambelani nomgangatho we-GB2626-2019 kwaye inokukhusela kuphela kuthuli olukhulu lwamasuntswana.
2. Iimaski ezingalukwanga: Uninzi lweemaski ezikhuselayo ezilahlwayo ziimaski ezingalukwanga, ezihluzwa ikakhulu kukuhluzwa ngokwasemzimbeni okuncediswa yi-electrostatic adsorption.
3. Imaski yelaphu: Imaski yelaphu inesiphumo kuphela sokugcina ubushushu ngaphandle kokucoca intwana yesuntswana (PM) kunye namanye amasuntswana amancinci.
4. Imaski yephepha: ifanelekile ukutya, ubuhle kunye namanye amashishini.Ineempawu zokungena komoya olungileyo, ukusetyenziswa ngokufanelekileyo kunye nokukhululeka.Iphepha elisetyenzisiweyo lihambelana nomgangatho we-GB / t22927-2008.
5. Iimaski ezenziwe ngezinye izinto, ezifana nezixhobo ezintsha zokucoca i-bio.
I-China lilizwe elikhulu kwishishini lemaski, livelisa malunga ne-50% yeemaski kwihlabathi.Ngaphambi kokuqhambuka, eyona mveliso yemihla ngemihla yeemaski eTshayina yayingaphezulu kwezigidi ezingama-20.Ngokwedatha, ixabiso lemveliso yoshishino lwemaski e-China Mainland likhule ngaphezulu kwe-10% ukusuka ngo-2015 ukuya ku-2019. Ngo-2019, imveliso yeemaski e-Chinese Mainland idlule kwiibhiliyoni ezi-5, ngexabiso le-10.235 yeebhiliyoni zeeyuan.Isantya sokuvelisa imaski ekhawulezayo ngamaqhekeza angama-120-200 / yesibini, kodwa inkqubo eqhelekileyo yokuhlalutya kunye ne-disinfection ithatha iintsuku ezi-7 ukuya kwisiqingatha senyanga.Ngenxa yokuba imaski yonyango inzalo nge-ethylene oxide, emva kokwenziwa inzala, kuya kubakho intsalela ye-ethylene oxide kwimaski, engayi kuvuselela nje indlela yokuphefumla, kodwa ibangele ne-carcinogens.Ngale ndlela, i-ethylene oxide eseleyo kufuneka ikhutshwe ngokuhlalutya ukuhlangabezana nomgangatho wokhuseleko.Kuphela emva kokuphumelela uvavanyo lunokuhanjiswa kwiimarike.
Ishishini lemaski laseTshayina liphuhlile laba lishishini eliqolileyo elinexabiso lemveliso yonyaka elingaphezulu kwe-10 yeebhiliyoni zeeYuan.Iqondo elifanelekileyo, ukusebenza kakuhle kokucoca, intuthuzelo kunye nokulula kweemaski nazo ziphuculwe kakhulu.Ukongeza kwiimaski zoqhaqho lwezonyango, zininzi iindidi ezincinci ezifana nokuthintela uthuli, uthintelo lwe-pollen kunye nokuhluzwa kwe-PM2.5.Iimaski zinokubonwa ezibhedlele, kwizityalo ezilungisa ukutya, imigodi, iintsuku zesmog zasezidolophini kunye nezinye izigcawu.Ngokwedatha yokubonisana nemithombo yeendaba ye-AI, ngo-2020, isikali semarike yoshishino lwemaski yaseTshayina luya kuba nokwanda okubalulekileyo kwisiseko sokukhula okuzinzileyo, ukuya kufikelela kwi-71.41 yeebhiliyoni zeeyuan.Ngo-2021, iya kubuyela umva kwinqanaba elithile, kodwa isikali sentengiso iyonke yeshishini lemaski lisakhula.
