Cov kua mem UV tsis haum rau txhua qhov xwm txheej. Piv txwv li, thaum muaj teeb meem nyiaj txiag, tus nqi ntawm cov kua mem UV feem ntau siab dua li cov kua mem uas siv dej lossis cov kua mem uas siv cov kuab tshuaj, uas yuav ua rau tus nqi ntawm kev luam ntawv loj nce ntxiv.
Ntxiv mus, kev siv cov kua mem UV xav tau cov khoom siv kho UV tshwj xeeb, uas feem ntau kim dua thiab kim dua los saib xyuas dua li cov khoom siv luam ntawv ib txwm muaj. Rau qee cov ntaub ntawv tshwj xeeb (xws li ntoo lossis qee yam hlau), qhov kev nplaum lossis kev ywj pheej ntawm cov kua mem UV yuav tsis zoo li cov kua mem ib txwm muaj.
Txawm li cas los xij, UV number case yeej yog qhov kev xaiv zoo tshaj plaws hauv ntau qhov xwm txheej, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas xav tau kev kho sai, kev ruaj khov siab, kev ua haujlwm xim ci, thiab kev tiv thaiv ib puag ncig siab. Piv txwv li, UV number case tuaj yeem kho tau tam sim ntawd hauv qab lub teeb ultraviolet, uas ua rau lub voj voog tsim khoom luv dua thiab txhim kho kev ua haujlwm zoo.
Nws kuj muaj kev nplaum zoo heev thiab tuaj yeem ua tiav cov txiaj ntsig zoo ntawm cov ntaub ntawv tsis nqus dej xws li iav, hlau, yas, thiab lwm yam. Tsis tas li ntawd, cov yam ntxwv tiv thaiv ib puag ncig ntawm UV number case kuj tso cai rau nws siv rau hauv cov cheeb tsam uas muaj kev cai nruj ntawm kev tu cev thiab kev tiv thaiv ib puag ncig, xws li cov khoom ntim khoom saib xyuas tawv nqaij thiab cov khoom siv kho mob.
