Kuwala kwa UV (ultraviolet) ndi mtundu wa radiation ya electromagnetic. Ili ndi kutalika kwake kwaufupi kuposa kuwala kowoneka, kotero sikuwoneka ndi maso, koma imatha kudziwika ndi zotsatira zake pazinthu zosiyanasiyana. Ma radiation a UV amatha kusintha mamolekyu am'mamolekyu, zomwe zimapangitsa kuti zinthu zisinthe, komanso zimapangitsa kuti zinthu zambiri zizitulutsa kapena kutulutsa kuwala. Ma radiation a UV amawononga kapangidwe ka ma polima, zomwe zimapangitsa kutaya mphamvu komanso kusinthika kwamtundu ndi kusweka. Amatengekanso ndi mitundu yambiri ya inki ndi utoto, zomwe zimapangitsa kuti zisinthe mtundu. UV kuwala zimachitika mwachilengedwe mu kuwala kwa dzuwa ndipo amathanso kutulutsidwa ndi magwero opangira kuwala.
Mafunde a nyali amatha kukhudza momwe angaletsere ma virus komanso chitetezo ndi nkhawa zomwe zingakhalepo. Kuyesa nyali kungavumbulutse ngati ndi kuchuluka kwa mafunde owonjezera omwe akutulutsa. Popeza ma LED alibe mercury, ali ndi mwayi kuposa nyali zotsika kwambiri za mercury
Pakalipano, zoyesera zimatsimikizira kuti kuwala kwa UVC ndi mtundu wothandiza kwambiri wa kuwala kwa ultraviolet kupha mabakiteriya. Itha kugwiritsidwa ntchito kupha tizilombo toyambitsa matenda pamalo, mpweya ndi zakumwa. Kuwala kwa UVC kumapha majeremusi ngati ma virus ndi mabakiteriya powononga mamolekyu monga ma nucleic acid ndi mapuloteni. Izi zimapangitsa kuti mabakiteriya asamachite zomwe akufunikira kuti apulumuke.
Coronavirus yatsopano idayesedwa m'zikhalidwe zamadzimadzi pogwiritsa ntchito kuwala kwa UVC mu kafukufuku waposachedwa wofalitsidwa mu American Magazine of Infection Control.
Kafukufuku wina yemwe adanenedwa mu AJIC adawunika pogwiritsa ntchito nyali inayake ya UVC kuti athetse SARS-CoV-2 pamalo a labu. Malinga ndi kafukufukuyu, ma radiation a UVC adapha 99.7% ya ma coronavirus amoyo mkati mwa masekondi 30.
Kafukufuku yemwe adafufuzidwa pogwiritsa ntchito kuwala kwa UVC kutali kuti athetse mitundu iwiri ya ma coronavirus a anthu mkati mwa izi UVC m’magazini yasayansi yotchedwa Scientific Reports.
Kafukufuku waposachedwa mu American Journal of Infection Control (AJIC) adafufuza kugwiritsa ntchito nyali ya UVC kupha ma coronaviruses ambiri m'zikhalidwe zamadzimadzi. Kafukufukuyu adapeza kuti mphindi 9 za kuwala kwa UVC kungathe kuletsa kachilomboka.
Madzi, mpweya, malo ena ndi malo ndizovuta kuyeretsa. Nyali za UVC zitha kugwiritsidwa ntchito kuphera tizilombo m'malo awa. Mwachitsanzo, magetsi a UVC ndipo maloboti amagwiritsidwa ntchito kupha madzi, malo okhala m'zipinda zopanda anthu, komanso magalimoto akulu ngati mabasi magetsi a UVC angagwiritsidwe ntchito m'mipata yotseguka m'nyumba kuti inactivate mavairasi airborne ndi tizilombo tina. Kuunikira kumayikidwa pamwamba pa chipindacho pamtunda wosachepera mamita 2.4. Imapindika kuti iwalire mopingasa kapena molunjika padenga osati pansi. Mafani ndi magetsi amaonetsetsa kuti mpweya umayenda kuchokera pansi pa chipinda kupita pamwamba komanso mosiyana. Pochita izi, mpweya wonse m'chipindamo umawonekera magetsi a UVC , amene amalepheretsa mabakiteriya oyenda mumlengalenga magetsi a UVC Angathenso kuikidwa m'mapaipi a mpweya kuti atseke mavairasi oyendetsa mpweya ndi mabakiteriya ena omwe amasuntha chipinda ndi chipinda.
Ndikofunika kuti magetsi a UVC ntchito mu zipinda ndi anthu musati kugunda chipinda. Kuwala kwake kwamphamvu kwambiri kwa UVC kumatha kuwononga maso ndi khungu m'masekondi chabe.
Chimodzi mwazovuta zake ndikuti kuwala kwa UVC kumafuna kukhudza kwachindunji kuti kukhale kothandiza.
· Sizikudziwikabe kuti mawonekedwe a UVC amtundu wanji, monga kutalika kwa mafunde ndi mlingo, ndiwothandiza kwambiri kupha SARS-CoV-2.
· Maso anu kapena khungu lanu likhoza kuonongeka ngati likumana ndi mitundu ina ya kuwala kwa UVC.
· Nyali zowunikira za UVC zomwe zimaperekedwa kuti zizigwiritsidwa ntchito kunyumba nthawi zambiri zimakhala zocheperako. Zotsatira zake, nthawi yomwe imatengera kuwononga mabakiteriya ikhoza kukhala yayitali.
· Magetsi a UVC amatha kupanga ozoni kapena mercury, zomwe zitha kuvulaza anthu.
Nayi tsatanetsatane kuti mudziwe zomwe zingakuthandizireni.
M'mbuyomu, ma radiation a UVC nthawi zambiri amapangidwa ndi nyali zotsika kwambiri za mercury, zomwe zimatulutsa kwambiri pa 254 nm (>90%). Mababu amtunduwu amathanso kupanga mafunde ena. Nyali zina zilipo zomwe zimapanga osati kuwala kowoneka ndi infrared komanso mitundu yosiyanasiyana ya mafunde a UV.
Mtundu wina wa nyali wokhala ndi mpweya wochuluka wa pafupifupi 222 nm umatchedwa "nyali ya excimer."
Nyalizi, zomwe zimatulutsa kuwala kwachidule kwa UV, kuwala kowoneka bwino, komanso kuwala kwa infrared komwe kumayendetsedwa kuti atulutse cheza cha UVC makamaka, nthawi zina amagwiritsidwa ntchito m'zipatala kuyeretsa malo ochitira opaleshoni ndi madera ena. Izi zimagwiritsidwa ntchito ngati palibe anthu m'deralo.
Zikukhalanso zosavuta kupeza ma LED omwe amatulutsa kuwala kwa UV. Nthawi zambiri, ma radiation ang'onoang'ono amapangidwa ndi ma LED. Popeza ma LED alibe mercury, ali ndi mwayi kuposa nyali zotsika kwambiri za mercury. Ma LED amatha kuwongolera kwambiri komanso kukhala ndi malo ang'onoang'ono.
Tsopano, mwaphunzira kuti magetsi a UVC ali ndi vuto linalake la kachilombo ka korona, ndikugwiritsa ntchito magetsi a UVC kwa disinfection tsiku lililonse. Malingaliro a kampani Zhuhai Tianhui Electronic Co., Ltd ndi yankho wangwiro kugula wanu magetsi a UVC . 2002 adawona kukhazikitsidwa kwa Zhuhai Tianhui Electronic Co., Ltd. Izi ndizokhazikika pakupanga, zapamwamba kwambiri Wopanga ma LED a UV Umene umakhala wapadera UVC Ndi Magetsi a UV Makonzedwe osiyanasiyana Njira ya UV LED Mafuniro. Zimaphatikiza kafukufuku ndi chitukuko, kupanga, kugulitsa, ndi Njira ya UV LED Ndalama.
Woimira wamkulu ku Greater China ndi Seoul Semiconductor SVC, ndi mgwirizano womwe umatenga zaka zoposa khumi. Zaka makumi awiri zachidziwitso chambiri mkati mwa UV LED msika, kudziwa kugwiritsa ntchito Magetsi a UV m'magawo osiyanasiyana, ndipo ali woyenerera kupatsa makasitomala chitukuko ndi kafukufuku. Itha kuyankha mwachangu zopempha zamakasitomala ndikuthandizira makasitomala kusanthula ndi kuthetsa mavuto nthawi yoyamba.
Kafukufuku wasonyeza kuti magetsi a UVC amatha kupha kachilombo ka SARS-CoV-2 pamtunda mpaka 99.7%. UVC waphatikizidwa munjira zoyeretsera zipatala zambiri ndi mabungwe azachipatala. Zipatala, malo ochitirako opaleshoni, zipinda zochitira opaleshoni ndi zida zamankhwala zimapindula ndi mankhwala ophera tizilombo toyambitsa matenda a UVC kuti azikhala aukhondo komanso kuchotsa tizilombo toyambitsa matenda, kuphatikizapo tizilombo tambiri tosamva maantibayotiki. Kuyeretsa tsiku ndi tsiku kuthanso kugwiritsa ntchito nyali za UVC popha tizilombo toyambitsa matenda.
