222nm UVC LED teeb tuaj yeem tua tus kabmob coronavirus thiab tsis muaj mob rau tib neeg lub cev?
Txij li thaum muaj tus kab mob coronavirus tshiab, ntau lub zog thoob ntiaj teb tau nqis peev hauv kev tshawb fawb txog tshuaj tua kab mob thiab ua kom tsis muaj menyuam. Kev tshawb fawb txog seb cov kab hluav taws xob sib sib zog nqus puas tuaj yeem tua tus kabmob coronaviruses tseem tab tom ua, thiab muaj qee qhov kev tshawb fawb ua pov thawj tias UVC thev naus laus zis tuaj yeem tua tus kabmob coronaviruses zoo.
Violes UV LED thev naus laus zis, piv txwv li, tau pom tias ua tiav tua 99.9 feem pua ntawm tus kabmob tshiab no hauv 30 vib nas this. Tsis tas li ntawd, cov tshuaj tua kab mob siab tshaj -lub zog UVC LED teeb tso tawm los ntawm Atomic Blue, Texas-raws li LED lub tuam txhab, tau raug sim los ntawm National Institutes of Health nyob rau hauv siab - qauv kuaj kev ua haujlwm los tua kab mob N95 lub qhov ncauj qhov ntswg thiab cov hlau, uas tuaj yeem tshem tawm 99.9999 feem pua ntawm Novel coronavirus.
Tsis ntev los no, raws li kev tshaj tawm xov xwm txawv teb chaws, kev sim ua los ntawm Columbia University hauv Tebchaws Meskas kuj tau pom tias nyob deb -UVC (far-UVC) lub teeb tuaj yeem tua tus kabmob coronaviruses ntawm qhov chaw hauv feeb.
The report shows that a research team at Columbia University's Radiology Research Center is conducting experiments on far-UVC light. According to the researcher, the far UVC wavelength is 222nm, which is safe for the human body, but can still kill viruses.
David Brenner, tus thawj coj ntawm lub chaw tshawb fawb, tau hais tias nyob deb UVC nrog lub wavelength ntawm 222nm tsis tuaj yeem nkag mus rau ntawm daim tawv nqaij lossis lub qhov muag, uas txhais tau hais tias nws tuaj yeem siv rau hauv qhov chaw kaw thiab muaj neeg coob coob uas muaj kev phom sij txaus ntshai, thiab muaj peev xwm ua tau zoo nyob rau hauv qhov chaw. tam sim no tshiab coronary pneumonia kab mob. Lub sijhawm los ua ke.

Nws tau tshaj tawm tias thaum ntxov li xyoo 2013, pab pawg Columbia University tau pib kawm txog cov tshuaj tua kab mob ntawm qhov deb -UVC ntawm cov tshuaj - cov kab mob resistant. Tom qab ntawd, pab pawg tshawb fawb tau kawm txog qhov cuam tshuam ntawm qhov deb -UVC ntawm cov kab mob xws li tus kab mob khaub thuas, thiab tsuas yog nyuam qhuav pib tig lawv lub siab rau tus mob coronavirus.
Brenner tau hais tias lawv tau pib qhov kev sim peb lossis plaub lub lis piam dhau los thiab tau tsim kom deb li deb -UVC teeb tuaj yeem tua tus kabmob coronaviruses ntawm qhov chaw hauv feeb.
Tom ntej no, pab neeg tshawb fawb npaj yuav sim seb qhov deb ntawm -UVC teeb tuaj yeem tua cov kab mob uas raug tshem tawm hauv huab cua, xws li cov kis thaum tus neeg mob hnoos lossis txham.
Nyob rau tib lub sijhawm, lawv tseem yuav sim kom pom tias lub teeb tsis muaj teeb meem rau tib neeg. Rau 40 lub lis piam, lub chaw kuaj mob tau nthuav tawm cov nas kom deb li deb -UVC teeb, yim teev hauv ib hnub, tsib hnub hauv ib lub lis piam, ntawm 20 npaug ntawm kev siv tib neeg. Tom qab kuaj lub qhov muag thiab tawv nqaij ntawm nas, pab neeg tshawb fawb pom tias cov nas tsis pom qhov txawv txav. Qhov kev sim yuav txuas ntxiv rau ntau tshaj 20 lub lis piam.
Tam sim no, txawm hais tias pab pawg tshawb fawb tau xa cov txiaj ntsig ua ntej mus rau phau ntawv xov xwm Nature, cov txiaj ntsig tsis tuaj yeem lees paub los ntawm lub zej zog kev tshawb fawb kom txog thaum tag nrho cov kauj ruam ntxiv tau ua tiav.
In addition, it was reported in April that Japan's Kobe University (Kobe University) and Japanese LED component manufacturer Ushio (Ushio) also proposed that UVC radiation with a wavelength of 222nm is harmless to human skin and eyes.
Kev tshawb fawb ntawm ob tog pom tau hais tias cov nyhuv sterilization ntawm lub teeb ultraviolet sib sib zog nqus nrog lub wavelength ntawm 222nm thiab 254nm yog sib npaug ntawm lub peev xwm los tshem tawm cov kab mob ntawm daim tawv nqaij. Nyob rau tib lub sijhawm, tom qab kuaj cov nas, nws kuj tau pom tias UVC lub teeb nrog lub wavelength ntawm 222nm tsis ua mob rau daim tawv nqaij thiab qhov muag ntawm nas. tsim cov teebmeem phem.
Qhov tseeb, tseem muaj ntau qhov kev tsis sib haum xeeb hauv kev lag luam txog cov lus thov tias UVC lub teeb tuaj yeem tua tus kabmob coronavirus thiab UVC lub teeb nrog lub wavelength ntawm 222nm tsis muaj teeb meem rau tib neeg lub cev. Muaj ntau qhov kev saib xyuas los ntawm txhua qhov chaw ntawm lub neej, thiab ntau thiab ntau cov ncauj lus kom ntxaws yuav tsum tau ua pov thawj cov txiaj ntsig no. (Compile: LEDinside Janice)
