Sankhani sikudalira kusintha.Mkonzi wathu adasankha izi ndi zogulitsa chifukwa tikuganiza kuti mudzasangalala nazo pamitengo iyi.Mukagula katundu kudzera pamaulalo athu, titha kupeza ma komisheni.Monga nthawi yofalitsidwa, mitengo ndi kupezeka kwake ndizolondola.
Patatha chaka chokhazikika kwa masks, asayansi ndi akatswiri azachipatala m'dziko lonselo akuphunzira kuti ndi nsalu iti yomwe ingatiteteze ku coronavirus.Ndizofunikira kudziwa kuti ochita kafukufuku akuphunzira za silika.Mu Seputembara 2020, ofufuza ku Yunivesite ya Cincinnati adawonetsa kuti poyerekeza ndi ulusi wa thonje ndi poliyesitala, silika ndiye wothandiza kwambiri poletsa madontho ang'onoang'ono a aerosol kuti asalowe kudzera mu masks kumalo opangira ma labotale - kuphatikiza madontho opumira omwe ali ndi Covid-19, Ndipo amamasulidwa akadwala. anthu amayetsemula, kutsokomola kapena kulankhula ndi kachilomboka.Malinga ndi Centers for Disease Control and Prevention (CDC), iyi ndi njira yayikulu yomwe coronavirus imafalira kuchokera kwa munthu kupita kwa munthu.
Dr. Patrick A. Gera, pulofesa wothandizira mu Dipatimenti ya Biological Sciences ku yunivesite ya Cincinnati, anafotokoza kuti chifukwa cha hydrophobicity yake yapadera-kapena mphamvu yake yothamangitsira madzi-poyerekeza ndi zipangizo zina, silika imathandiza kuti madontho ambiri a madzi asalowe. chigoba.pakati.Wolemba nawo kafukufukuyu.Kuphatikiza apo, kafukufukuyu adapeza kuti chigoba cha silika chikayikidwa pa chopumira (mtundu wa chigoba chowirikiza) chomwe chimafunika kuvala kangapo, silika amatha kuteteza zida zodzitetezera monga masks a N95.Komabe, CDC imalimbikitsa kuti musagwiritse ntchito zopumira monga N95 ndi KN95 masks a masks apawiri.Tikulimbikitsidwa kuvala chigoba chimodzi chokha cha KN95 nthawi imodzi: "Musagwiritse ntchito chigoba chachiwiri pamwamba kapena pansi pa chigoba cha KN95."
"Pankhani yopanga masks, ikadali ku Wild West," adatero Guerra."Koma tikuyang'ana njira zogwiritsira ntchito sayansi yoyambira ndikugwiritsa ntchito zomwe tikudziwa kuti tisinthe."
Tidakambirana ndi akatswiri momwe tingagulire masks a silika, ndikusonkhanitsa masks abwino kwambiri amsika pamsika kuchokera kumitundu monga Slip ndi Vince.
Chigoba cha silika cha Slip chimapangidwa ndi silika wa mabulosi 100% mbali zonse ziwiri, ndipo mkati mwake amapangidwa ndi thonje 100%.Chigobacho chimakhala ndi ndolo zotanuka zosinthika, ma seti awiri a mapulagi a silicone olowa m'malo ndi chingwe champhuno chosinthika, chomwe chingalowe m'malo mwa mphuno 10.Silika wa Slip amagulitsidwa ndi matumba osungira, ndipo chivundikirocho chimabwera m'mitundu isanu ndi itatu, kuchokera pamitundu yolimba monga rose gold ndi pinki kupita kumapangidwe monga rose leopard ndi horizon.Slip amalimbikitsa kuyeretsa chigoba molingana ndi malangizo a pillowcase-kusamba m'manja kapena kusamba pamakina, Slip amalimbikitsa kuyanika chigobacho.Slip imagulitsanso mafuta odzola a silika omwe amagwiritsidwa ntchito kutsukira zinthu zake.
Chigoba cha Vince chimagwiritsa ntchito kapangidwe kansanjika zitatu: 100% wosanjikiza wakunja wa silika, zosefera za poliyesitala ndi wosanjikiza wamkati wa thonje.Mask amabweranso ndi thumba la thonje.Potsuka chigobacho, Vince amalimbikitsa kuti aziviika m'madzi ofunda okhala ndi zotsukira kapena sopo, kenako ndikuwumitsa.Pa chigoba chilichonse chogulitsidwa, Vince apereka $ 15 ku American Civil Liberties Union.Masks amapezeka mumitundu isanu: pinki, siliva imvi, minyanga ya njovu, yakuda ndi yabuluu ya m'mphepete mwa nyanja.
Chigoba cha silika cha Blissy chimapangidwa ndi manja ndi 100% silika wa mabulosi oyera.Amapezeka mumitundu inayi: siliva, pinki, wakuda ndi tayi-dye.Chigobachi chimakhala ndi mbedza zosinthika m'makutu ndipo chimatha kuchapa ndi makina.
Chigoba cha silika ichi chimapangidwa ndi silika wa mabulosi 100% ndipo amabwera ndi thumba lazosefera lamkati ndi ndowe zamakutu zosinthika.Chigobachi chimabwera mumitundu 12, kuphatikiza buluu, utoto wofiirira, woyera, taupe ndi wobiriwira wa nandolo.
Chigoba cha nkhope ya silika ya NIGHT chapangidwa ndi nsalu yansanjika zitatu ndipo chimabwera ndi thumba losefera.Chigobacho chilinso ndi zosefera zisanu ndi ziwiri zotaya.Ili ndi mzere wosinthika wa mphuno ndi zokowera zamakutu zosinthika.Chigobachi chimatha kutsukidwa ndi madzi ozizira m'malo osakhwima ndipo chimapezeka mumitundu inayi: blush, champagne, emarodi ndi bronze.
Chigoba cha silika cha D'aire chapangidwa ndi mitundu yosiyanasiyana monga kubisala, nyenyezi yapakati pausiku, ndi mitundu yolimba monga rouge, wakuda ndi koko.Ili ndi mlatho wosinthika wa mphuno, zokowera zamakutu zosinthika ndi matumba osefera.Amapezeka m'magulu atatu: ang'onoang'ono, apakati ndi aakulu.Chigobacho chikhoza kutsukidwa ndi makina m'madzi ozizira m'malo osakhwima.D'aire amagulitsanso zosefera zotayidwa, zomwe zimakhala zomangika kuti zigwirizane ndi masks ake a silika.Pali zosefera 10 kapena 20 mu paketi.
Chigoba cha silika cha Claire & Clara chimakhala ndi zigawo ziwiri za nsalu.Amakhalanso ndi zokowera zamakutu zosinthika.Mtunduwu umatulutsa mkaka wokhala ndi matumba opanda zosefera.Pamwamba pa silika ali ndi mitundu isanu: buluu wowala, pinki, woyera, navy blue ndi violet.Claire & Clara amagulitsanso paketi ya zosefera zisanu zotayidwa.
Laborator ya Guerra idapeza kuti "masks a silika amatha kubweza madontho pamayeso opopera komanso masks otayidwa otayidwa."Koma masks a silika ali ndi mwayi wina kuposa masks opangira opaleshoni: amatha kutsukidwa ndikugwiritsidwanso ntchito.Komanso, Guerra ananena kuti silika ali ndi electrostatic properties, kutanthauza kuti ndi bwino charged.Chigoba chikakhala ndi silika wakunja, tinthu tating'onoting'ono timamamatira, Guerra adanenanso, kotero kuti tinthu tating'ono ting'onoting'ono sitidutsa pansalu.Chifukwa cha mkuwa womwe umapezeka mmenemo, silika alinso ndi antiviral ndi antibacterial properties.
Pomaliza, monga tonse tikudziwira, silika ndi wabwino pakhungu lanu.Michele Farber, MD, dokotala wotsimikiziridwa ndi gulu la Dermatology Gulu la Schweiger Dermatology, amalimbikitsa ma pillowcase a silika a khungu lokhala ndi ziphuphu komanso tcheru chifukwa samapanga kugundana kwakukulu monga nsalu zina choncho samayambitsa kupsa mtima.Malangizowa tsopano atha kugwiritsidwa ntchito pa masks.Farber ananena kuti poyerekezera ndi mitundu ina ya nsalu, silika satenga mafuta ambiri ndi dothi, komanso satenga chinyezi chochuluka pakhungu.
Kutengera kafukufuku wake, Guerra amalimbikitsa masks awiri pophimba chigoba cha silika pa masks omwe amatha kutaya.Chigoba cha silika chimakhala ngati chotchinga cha hydrophobic-molingana ndi CDC, chifukwa chigoba chonyowa sichigwira ntchito bwino-ndipo kuphatikiza uku kumakupatsani chitetezo chambiri.
Farber adanenanso kuti masks apawiri sangakupatseni phindu la khungu la masks a silika.Koma adaonjeza kuti kutengera momwe zinthu ziliri, kuvala masks a silika olimba, owoneka bwino, okhala ndi zosefera ndi njira yovomerezeka ngati masks apawiri.Ponena za masks oyera a silika, Farber ndi Guerra akuti nthawi zambiri mumatha kutsuka ndi dzanja kapena makina, koma zimatengera malangizo amtunduwo.
Guerra adachita chidwi ndi silika ngati chigoba chifukwa mkazi wake anali dotolo ndipo adagwiritsanso ntchito chigoba chake cha N95 kwa masiku ambiri mliri utayamba.Laborator yake nthawi zambiri imaphunzira kapangidwe ka mbozi za njenjete za silika, ndikuyamba kuphunzira kuti ndi nsalu ziti zomwe zili zabwino kwambiri kwa ogwira ntchito kutsogolo kuti agwiritse ntchito masks osanjikiza kawiri kuti ateteze zopumira, komanso nsalu zomwe zimatha kupanga masks ogwiranso ntchito kwa anthu.
Pa kafukufukuyu, labotale ya Guerra idasanthula hydrophobicity ya thonje, polyester, ndi nsalu za silika poyesa kuthekera kwawo kuthamangitsa madontho ang'onoang'ono amadzi aerosol.Laborator idawunikanso kupuma kwa nsalu komanso momwe kuyeretsa pafupipafupi kumakhudzira kuthekera kwawo kukhalabe ndi hydrophobicity pambuyo poyeretsa mobwerezabwereza.Guerra adanena kuti labotale yake idaganiza kuti asaphunzire kuchuluka kwa kusefera kwa silika - kofala m'mayesero ofanana - chifukwa ofufuza ena ambiri akuyesetsa kale kuyesa luso la kusefera kwa nsalu za silika.
Dziwani mwatsatanetsatane nkhani zandalama zamunthu, ukadaulo ndi zida, thanzi ndi zina zambiri, ndipo mutitsatire pa Facebook, Instagram ndi Twitter kuti mudziwe zambiri.
