Impendulo ye-COVID-19: Abavelisi kunye nabasasazi ababonelela ngemithombo yoncedo lwe-COVID-19 ico-arrow-default-right
Nje ukuba imaski yotyando yayingumtya welaphu obotshelelwe ebusweni bukagqirha okanye umongikazi, ngoku yenziwe ngelaphu elingalukwanga elenziwe ngepolypropylene kunye nezinye iiplastiki zokuhluza kunye nokukhusela.Ngokwenqanaba lokhuseleko olufunwa ngabasebenzisi, baneendlela ezininzi ezahlukeneyo kunye namanqanaba.Ngaba ujonge ulwazi oluthe kratya malunga neemaski zotyando ukuhlangabezana neemfuno zakho zokuthenga ezonyango?Senze esi sikhokelo ukucacisa ezinye zezinto ezisisiseko malunga nezi maski kunye nendlela ezenziwe ngayo.Ukuba unomdla wokufunda ngakumbi malunga nokwenza iziphefumli, iimpahla ezikhuselayo kunye nezinye izixhobo zokuzikhusela, ungandwendwela umboniso wethu wokwenziwa kwePPE.Unokujonga kwakhona inqaku lethu kwiimaski zelaphu eziphezulu kunye neemaski zotyando.
Iimaski zotyando ziyilelwe ukugcina igumbi lotyando lingenazintsholongwane kwaye zithintele iintsholongwane ezisempumlweni nasemlonyeni walowo uzinxibileyo ukuba zingcolise isigulane ngexesha lotyando.Nangona ziya zithandwa ngakumbi phakathi kwabathengi ngexesha lokuqhambuka okufana ne-coronavirus, iimaski zotyando azenzelwanga ukuhluza iintsholongwane ezincinci kunebhaktheriya.Ukufumana ulwazi oluthe kratya malunga nokuba loluphi uhlobo lwemaski olukhuselekileyo kwiingcali zonyango ezijongene nezifo ezinjenge-coronavirus, unokufunda inqaku lethu malunga nababoneleli abaphezulu abavunywe yi-CDC.
Kufuneka kuqatshelwe ukuba iingxelo zakutsha nje ezivela kwi-Healthline kunye ne-CDC zibonisa ukuba iimaski ezinevalvu okanye ii-vents zinokusasaza usulelo.Iimaski ziya kubonelela lowo uzinxibileyo ukhuseleko olufanayo njengeemaski ezingenamoya, kodwa ivalve ayiyi kuyithintela intsholongwane ukuba ingaphumi, nto leyo eya kuvumela abantu abangaziyo ukuba bosulelekile ukuba basasaze intsholongwane kwabanye.Kukwabalulekile ukuqaphela ukuba iimaski ezingenazo iimaski zinokusasaza intsholongwane.
Iimaski zotyando zahlulwe zaba ngamanqanaba amane ngokwesatifikethi se-ASTM, kuxhomekeke kwinqanaba lokhuseleko abalinika umntu ozinxibileyo:
Kufuneka kuqatshelwe ukuba iimaski zotyando azifani neemaski zotyando.Iimaski zisetyenziselwa ukuvala i-splashes okanye i-aerosols (efana nokufuma xa uthimla), kwaye zibotshelelwe ngokukhululeka ebusweni.Izinto zokuphefumla zisetyenziselwa ukuhluza amasuntswana aphuma emoyeni, afana neentsholongwane kunye neebhaktheriya, kwaye zenze itywina elijikeleze impumlo nomlomo.Xa isigulana sinosulelo lwentsholongwane okanye amasuntswana, umphunga okanye iigesi zikhona, kufuneka kusetyenziswe isixhobo sokuphefumla.
Iimaski zotyando zikwahlukile kwiimaski zotyando.Iimaski zotyando zisetyenziswa kwiindawo ezicocekileyo ezibhedlele, kubandakanywa amagumbi okhathalelo olunzima kunye neewadi zokubeleka, kodwa azivunywanga ukuba zisetyenziswe kwiindawo ezingcolileyo njengamagumbi otyando.
Ukusukela ngoNovemba ka-2020, iCDC iye yahlaziya izikhokelo zayo zokusetyenziswa kweemaski ukuvumela izibhedlele kunye namanye amaziko onyango ukuba andise izixhobo ngexesha lemfuno egqithisileyo.Isicwangciso sabo silandela uthotho lwamanyathelo kwiimeko ezingxamisekileyo ngokwandayo ukusuka kwimisebenzi eqhelekileyo ukuya kwimisebenzi yobunzima.Amanye amanyathelo kaxakeka aquka:
Kutshanje, i-ASTM iphuhlise iseti yemigangatho yeemaski zomgangatho wabathengi, apho iimaski zeklasi I zinokuhluza iipesenti ezingama-20 zamasuntswana angaphezu kwe-0.3 microns, kwaye iimaski zeklasi II zinokuhluza i-50% yamasuntswana angaphezu kwe-0.3 microns.Nangona kunjalo, ezi zenzelwe ukusetyenziswa kwabathengi kuphela, hayi ukusetyenziswa kwezonyango.Ukuza kuthi ga kwixesha lokubhalwa, i-CDC ayizange ihlaziye izikhokelo zayo ukujongana nomba wokuba ezi maski (ukuba zikhona) zinokusetyenziswa ngabasebenzi bezonyango ngaphandle kwePPE efanelekileyo.
Iimaski zotyando zenziwe ngamalaphu angalukwanga, anokucoca iibhaktheriya ezingcono kunye nokuphefumla, kwaye azityibiliki kancinci kuneengubo ezilukiweyo.Izinto eziqhelekileyo ezisetyenziselwa ukwenza i-polypropylene, enobunzima be-20 okanye i-25 grams ngemitha yesikwere (gsm).Iimaski zingenziwa kwakhona nge-polystyrene, i-polycarbonate, i-polyethylene okanye i-polyester.
Imathiriyeli yemaski engama-20 ye-gsm yenziwe kusetyenziswa inkqubo ye-spunbond, ebandakanya ukukhupha iplastiki etyhidiweyo kwibhanti lokuhambisa.Izinto eziphathekayo zikhutshelwa kwiwebhu, apho imicu ibambelela omnye komnye njengoko ipholile.Ilaphu le-25 gsm lenziwe ngetekhnoloji enyibilikayo, eyinkqubo efanayo apho iplastiki ikhutshelwa ngokufa kunye namakhulu emilomo emincinci kwaye ivuthelwe kwimicu ecolekileyo ngomoya oshushu, iphinde ipholiswe kwakhona kwaye ibekwe kwibhanti yokuhambisa i上胶。 Kwiglu .Ubukhulu bezi fiber bungaphantsi kwe micron enye.
Iimaski zotyando zibandakanya ulwakhiwo olunemigangatho emininzi, ngokuqhelekileyo umaleko welaphu elingalukwanga ligqunywe kumaleko welaphu.Ngenxa yobume bawo obunokulahlwa, amalaphu angalukwanga anexabiso eliphantsi kwaye acocekile ukuwenza kwaye enziwe ngamaleko amathathu okanye amane.Ezi maski ezilahlwayo zihlala zenziwe ngamaleko amabini okucoca, anokucoca ngokufanelekileyo iintsholongwane kunye namanye amasuntswana amakhulu kune-1 micron.Nangona kunjalo, inqanaba lokuhluza imaski lixhomekeke kwifayibha, indlela yokuvelisa, ubume bomnatha wefiber kunye nemilo enqamlezayo yefiber.Iimaski zenziwa kumgca womatshini ohlanganisa amalaphu angalukwanga kwi-spools, idibanisa umaleko kunye ne-ultrasound, kwaye iprinta iibhendi zempumlo, amacici kunye nezinye iindawo kwimaski.
Emva kokuba imaski yotyando yenziwe, kufuneka ivavanywe ukuqinisekisa ukhuseleko lwayo kwiimeko ezahlukeneyo.Kufuneka baphumelele iimvavanyo ezintlanu:
Umzi-mveliso wempahla kunye nabanye abenzi bamachiza enziwe afana nalawo aveliswe ngabenzi banokuba ngabavelisi bemaski, kodwa mininzi imiceli mngeni ekufuneka yoyiswe.Oku akusiyo inkqubo yobusuku, kuba imveliso kufuneka ivunywe ngamaziko amaninzi kunye nemibutho.Imiqobo ibandakanya:
Nangona kukho ukunqongophala kwezixhobo zeemaski zotyando ngenxa yobhubhane oqhubekayo, iimodeli zemithombo evulekileyo kunye nemiyalelo yeemaski ezenziwe ngezinto eziqhelekileyo ziye zavela kwi-Intanethi.Nangona ezi zeze-DIYers, zinokusetyenziswa njengendawo yokuqala kwiimodeli zeshishini kunye nemveliso.Sifumene imizekelo emithathu yeepateni zemaski kwaye sinike amakhonkco kwiindidi zokuthenga kwi-Thomasnet.com ukukunceda ukuba uqalise.
Imaski ka-Olsen: Le maski yenzelwe ukuba inikelwe ezibhedlele, eya kuthi yongeze ibhande leenwele kunye nentambo yewax ukuze ilingane ngcono kubasebenzi bezonyango, kwaye ifake isihluzi se-micron eyi-0.3.
I-Fu Mask: Le webhusayithi inevidiyo yomyalelo wendlela yokwenza le maski.Le ndlela ifuna ukuba wenze umlinganiselo wesangqa sentloko.
Ipateni yemaski yelaphu: Sew It Online imaski ibandakanya uyilo lwepateni kwimiyalelo.Nje ukuba umsebenzisi eprinte imiyalelo, banokusuka bakhuphe ipateni kwaye baqalise ukusebenza.
Ngoku njengoko sizicacisile iintlobo zeemaski zotyando, ukuba zenziwa njani, kunye neenkcukacha zemingeni ejongene nayo iinkampani ezizama ukungena ebaleni, siyathemba ukuba oku kuya kukunceda ukuba ufumane ngokufanelekileyo ngakumbi.Ukuba ukulungele ukuqalisa ukuhlola ababoneleli, siyakumema ukuba ujonge iphepha lethu lokufumanisa umthengisi, eliqulethe ulwazi oluneenkcukacha kubathengisi bemaski botyando abangaphezu kwama-90.
Injongo yolu xwebhu kukuqokelela nokunikezela ngophando malunga neendlela zokwenza iimaski zotyando.Nangona sisebenza nzima ukucwangcisa nokudala ulwazi lwangoku, nceda uqaphele ukuba asinakuqinisekisa ukuchaneka kwe-100%.Nceda uqaphele ukuba uThomas akaboneleli, axhase okanye aqinisekise nayiphi na imveliso yomntu wesithathu, iinkonzo okanye ulwazi.UTomas akanxulumananga nabathengisi kweli phepha kwaye akanaxanduva lweemveliso kunye neenkonzo zabo.Asinaxanduva ngezenzo okanye umxholo wewebhusayithi zabo kunye neeapps.
