Impendulo ye-COVID-19

Impendulo ye-COVID-19: Abakhiqizi nabasabalalisi abahlinzeka ngemithombo yezokwelapha ze-COVID-19 ico-arrow-default-right
Lapho imaskhi yokuhlinza isiwumcu wendwangu eboshelwe ebusweni bukadokotela noma umhlengikazi, manje seyenziwe ngendwangu engalukiwe eyenziwe nge-polypropylene namanye amapulasitiki okuhlunga nokuvikela.Ngokwezinga lokuvikela elidingwa abasebenzisi, banezitayela namaleveli amaningi ahlukene.Ufuna ulwazi olwengeziwe mayelana namamaski okuhlinzwa ukuze uhlangabezane nezidingo zakho zokuthenga kwezokwelashwa?Sakhe lo mhlahlandlela ukuze siveze ezinye zezinto eziyisisekelo mayelana nalezi zimaski nokuthi zenziwa kanjani.Uma ungathanda ukufunda okwengeziwe mayelana nendlela yokwenza ama-respirators, izingubo zokuzivikela nezinye izinto zokuzivikela, ungavakashela uhlolojikelele lwethu lokukhiqiza lwe-PPE.Ungaphinda uhlole indatshana yethu kumaski wendwangu ephezulu kanye nemaski okuhlinzwa.
Amamaski okuhlinza aklanyelwe ukugcina igumbi lokuhlinza liyinyumba futhi avimbele amagciwane emakhaleni nasemlonyeni womuntu owafakile ekungcoliseni isiguli ngesikhathi sokuhlinzwa.Yize ziya ngokuya zithandwa phakathi kwabathengi ngesikhathi sokuqubuka okufana ne-coronavirus, imaski yokuhlinzwa ayiklanyelwe ukuhlunga amagciwane amancane kunamagciwane.Ukuze uthole ulwazi olwengeziwe mayelana nokuthi yiluphi uhlobo lwemaski oluphephe kakhudlwana kochwepheshe bezokwelapha ababhekene nezifo ezinjenge-coronavirus, ungafunda isihloko sethu ngabahlinzeki abaphezulu abagunyazwe yi-CDC.
Kufanele kuqashelwe ukuthi imibiko yakamuva evela ku-Healthline kanye ne-CDC ikhombisa ukuthi imaski enama-valve noma ama-vents maningi amathuba okuthi basabalalise ukutheleleka.Izifihla-buso zizonikeza umuntu ozigqokile isivikelo esifanayo nesamaski angangeni umoya, kodwa ivalvu ngeke ilivimbele ukuthi igciwane liphume, okuzovumela abantu abangazi ukuthi banalo ukuthi basakaze leli gciwane kwabanye.Kubalulekile futhi ukuqaphela ukuthi imaski engenamaski ingasakaza igciwane.
Amamaski okuhlinzwa ahlukaniswe ngamaleveli amane ngokuya ngesitifiketi se-ASTM, kuya ngezinga lokuvikela abalinikeza lowo oyigqokile:
Kufanele kuqashelwe ukuthi imaski yokuhlinza ayifani namaski okuhlinzwa.Izifihla-buso zisetshenziselwa ukuvimba ama-splashes noma ama-aerosol (njengomswakama lapho uthimula), futhi zinamathele ngokukhululekile ebusweni.Ama-respirators asetshenziselwa ukuhlunga izinhlayiya ezihamba emoyeni, njengamagciwane namagciwane, futhi zakhe uphawu ekhaleni nasemlonyeni.Uma isiguli sinokutheleleka ngegciwane noma izinhlayiya, umhwamuko noma amagesi akhona, kufanele kusetshenziswe umshini wokuphefumula.
Amamaski okuhlinzwa nawo ahlukile kumaski okuhlinzwa.Amamaski okuhlinza asetshenziswa ezindaweni ezihlanzekile ezibhedlela, okuhlanganisa izindawo zabagula kakhulu kanye namawodi okubeletha, kodwa awagunyaziwe ukuthi asetshenziswe ezindaweni ezingenalutho njengamagumbi okuhlinza.
Kusukela ngoNovemba 2020, i-CDC isibuyekeze imihlahlandlela yayo yokusebenzisa imaski ukuze ivumele izibhedlela nezinye izikhungo zezokwelapha ukuthi zandise izinsiza ngezikhathi zesidingo esikhulu.Uhlelo lwabo lulandela uchungechunge lwezinyathelo zezimo eziya ngokuya ngokuphuthuma kusukela ekusebenzeni okujwayelekile kuya ekusebenzeni kwezinhlekelele.Ezinye zezinyathelo eziphuthumayo zifaka:
Muva nje, i-ASTM ithuthukise isethi yezindinganiso zamamaski ebanga labathengi, lapho imaski yesigaba I ingahlunga ama-20% ezinhlayiya ezingaphezu kwama-microns angu-0.3, futhi imaski yeklasi II ingahlunga u-50% wezinhlayiya ezingaphezu kuka-0.3 microns.Nokho, lezi zenzelwe ukusetshenziswa abathengi kuphela, hhayi ezokwelashwa.Kusukela ngesikhathi sokubhala, i-CDC ayizange ibuyekeze imihlahlandlela yayo yokubhekana nenkinga yokuthi la maski (uma ekhona) angasetshenziswa ngabasebenzi bezokwelapha ngaphandle kwe-PPE efanele.
Amamaski okuhlinza akhiwe ngezindwangu ezingalukiwe, ezinokuhlunga okungcono kwamagciwane nokuphefumula, futhi azisheleli kakhulu kunezindwangu ezilukiwe.Izinto ezisetshenziswa kakhulu ukuzenza i-polypropylene, enobukhulu obungamagremu angama-20 noma angama-25 ngemitha yesikwele (gsm).Amamaski angenziwa futhi nge-polystyrene, i-polycarbonate, i-polyethylene noma i-polyester.
I-mask ye-gsm engu-20 yenziwa kusetshenziswa inqubo ye-spunbond, ebandakanya ukukhipha ipulasitiki encibilikisiwe ebhandeni lokuthutha.Impahla idluliselwa kuwebhu, lapho imicu inamathela komunye nomunye njengoba ipholile.Indwangu engu-25 gsm yenziwe ngobuchwepheshe obuncibilikayo obuvuthwe, okuyinqubo efanayo lapho ipulasitiki ikhishwa ngefasi elinamakhulukhulu emibhobho emincane bese ifuthwa ibe imicu ecolekile ngomoya oshisayo, ipholiswe futhi ibekwe ebhandeni elihambisayo 上胶。 Kuglue .Ububanzi bale micu bungaphansi kwe-micron eyodwa.
Amamaski okuhlinza ahlanganisa isakhiwo esinezingqimba eziningi, ngokuvamile ungqimba lwendwangu engalukiwe lumbozwa ungqimba lwendwangu.Ngenxa yemvelo yayo elahlayo, izindwangu ezingalukiwe zishibhile futhi zihlanzekile ukwenziwa futhi zenziwe ngezingqimba ezintathu noma ezine.Lezi zimaski ezilahlwayo ngokuvamile zenziwe ngezendlalelo ezimbili zokuhlunga, ezingasefa ngempumelelo amagciwane nezinye izinhlayiya ezinkulu kune-micron engu-1.Kodwa-ke, izinga lokuhlungwa kwemaski lincike ku-fiber, indlela yokukhiqiza, ukwakheka kwenethi ye-fiber kanye nokuma kwe-cross-sectional ye-fiber.Amamaski akhiqizwa emugqeni womshini ohlanganisa izindwangu ezingalukiwe kuma-spools, ashise izendlalelo nge-ultrasound, futhi aphrinte amabhande ekhala, amacici nezinye izingxenye kumaski.
Ngemuva kokuthi imaski yokuhlinzwa yenziwe, kufanele ihlolwe ukuze kuqinisekiswe ukuphepha kwayo ezimweni ezihlukahlukene.Kufanele baphumelele izivivinyo ezinhlanu:
Imboni yezingubo kanye nabanye abakhiqizi bezidakamizwa ezijwayelekile bangase babe abakhi bemaski abahlinzayo, kodwa kunezinselele eziningi okufanele uzinqobe.Lena akuyona inqubo yasebusuku, ngoba umkhiqizo kufanele ugunyazwe ama-ejensi amaningi nezinhlangano.Izithiyo zihlanganisa:
Yize kunokushoda kwezinto zokwakha imaski yokuhlinza ngenxa yalolu bhubhane oluqhubekayo, amamodeli emithombo evulekile nemiyalo yemaski enziwe ngezinto ezivame kakhulu sekuvele ku-inthanethi.Yize lezi ngeze-DIYers, zingasetshenziswa futhi njengesiqalo samamodeli webhizinisi nokukhiqiza.Sithole izibonelo ezintathu zamaphethini wemaski futhi sanikeza izixhumanisi ezigabeni zokuthenga ku-Thomasnet.com ukuze sikusize uqalise.
Imaski ka-Olsen: Le maski ihloselwe ukuthi inikelwe ezibhedlela, ezongeza ibhande lezinwele nentambo ye-wax ukuze ilingane kangcono nabasebenzi bezokwelapha ngabanye, bese ifaka isihlungi esingu-0.3 micron.
I-Fu Mask: Le webhusayithi iqukethe ividiyo yokufundisa yokuthi ungayenza kanjani le maski.Le modi idinga ukuthi ulinganise isiyingi sekhanda.
Iphethini yemaski yendwangu: Imaski ye-Sew It Online ihlanganisa ukwakheka kwephethini emiyalweni.Uma umsebenzisi esephrinte imiyalelo, angavele asike iphethini bese eqala ukusebenza.
Manje njengoba sesichazile izinhlobo zamamaski okuhlinzwa, ukuthi zenziwa kanjani, kanye nemininingwane yezinselelo izinkampani ezizama ukungena kulo mkhakha, sithemba ukuthi lokhu kuzokwenza ukuthi ukwazi ukuthola umthombo ngokuphumelelayo.Uma usukulungele ukuqala ukuhlola abahlinzeki, sikumema ukuthi uhlole ikhasi lethu lokuthola abahlinzeki, eliqukethe ulwazi oluningiliziwe ngabahlinzeki bemaski bokuhlinzwa abangaphezu kuka-90.
Inhloso yalo mbhalo ukuqoqa nokwethula ucwaningo ngezindlela zokukhiqiza imaski yokuhlinzwa.Yize sisebenza kanzima ukuze sihlele futhi sidale imininingwane yakamuva, sicela wazi ukuthi asikwazi ukuqinisekisa ukunemba okungu-100%.Sicela futhi uqaphele ukuthi uThomas akanikezi, akatusi noma akaqinisekisi noma yimiphi imikhiqizo, amasevisi noma ulwazi lomuntu wesithathu.UThomas akahlangene nabathengisi kuleli khasi futhi akanasibopho ngemikhiqizo namasevisi abo.Asinasibopho ngezinqubo noma okuqukethwe kwamawebhusayithi abo nezinhlelo zokusebenza.
