Dab tsi yog 365nm UV Teeb siv rau?
UV teeb yog ib hom muaj zog tshaj plaws ntawm lub teeb muaj; nws muaj ntau yam kev siv. Nws tuaj yeem siv los rhuav tshem cov kab mob, ua kom cov polymers tawv, thiab kho cov resins. Tus German physicist Johann Wilhelm Ritter Von Hoehn ua qhov kev tshawb pom hauv 1800s thaum Ritter pom cov lus teb ntawm UV teeb, lossis pom tsis pom ntawm qhov kawg ntawm cov spectrum, thiab cov ntawv nyiaj chloride nws tau siv rau nws qhov kev sim. Nws pom tias daim ntawv browned sai dua los ntawm UV hluav taws xob ntau dua los ntawm cov pom.
Txij thaum ntawd los, peb tau ua tiav zoo hauv peb txoj kev siv hluav taws xob UV thiab kawm raws nraim li nws muaj peev xwm tiag tiag. Tsis muaj UV lub teeb muaj zog dua 365 nm.
UV Teeb ntawm 365 nm yog dab tsi thiab nws siv li cas?
Peb tau tshawb pom tias lub wavelength ntawm 365 nm muaj txiaj ntsig zoo hauv kev tshem tawm cov kab mob, suav nrog Methicillin-resistant Staphylococcus Aureus (MRSA). Qhov no yog vim nws lub zog siab, uas tuaj yeem yaj cov kab mob ntawm cov phab ntsa ntawm tes.
Ib hom kab mob tua kab mob, lossis tua kab mob, lub teeb ntawm lub wavelength hu ua 365 nm UV teeb. Cov kab mob muaj xws li cov kab mob, fungus, pwm spores, kab mob, thiab lwm yam raug rhuav tshem los ntawm lub teeb no. Nws kuj tseem pab tiv thaiv cov kab mob no los ntawm kev loj hlob ntawm qhov chaw.
Txij li thaum lub teeb lub wavelength nyob nruab nrab ntawm 320 thiab 400 nm, nws belongs rau UV spectrum. Lub zog yog siab dua nyob rau hauv luv luv wavelength tshaj nyob rau hauv ntev sawv daws yuav.
Organic cov ntaub ntawv xws li daim tawv nqaij, plaub hau, textiles, polymers, ntoo, ntawv, xim, thiab lwm yam absorbs lub zog no. Cov khoom siv tshuaj lom neeg cov tshuaj tiv thaiv los ntawm UV hluav taws xob uas ua rau cov phab ntsa ntawm tes puas lossis hloov nws cov qauv molecular.
Peb xa mus rau cov txheej txheem no raws li cov tshuaj tiv thaiv photochemical.
Vim tias qhov wavelength no ntog ntawm lub teeb pom kev thiab UVC hluav taws xob, nws muaj txiaj ntsig zoo ntawm kev rhuav tshem cov kab mob. Txij li thaum pom lub teeb tsis tuaj yeem nkag mus rau ntawm daim tawv nqaij, nws tsis tuaj yeem siv los tua kab mob lossis kho. Ntawm qhov tod tes, UVC lub teeb muaj zog heev thiab yuav ua mob rau koj ob lub qhov muag. Qhov nruab nrab ntawm cov spectrum muaj qhov zoo tshaj plaws wavelengths.
