Kev siv UV number case muaj cov txiaj ntsig zoo li nram no:
Qhuav sai: Cov kua UV qhuav tam sim ntawd thaum lub sijhawm luam ntawv, yog li tsis tas yuav siv sijhawm ntxiv kom qhuav tom qab luam ntawv. Qhov no ua rau muaj kev tsim khoom ntau dua thiab ua haujlwm sai dua.
Kev ruaj khov: Cov kua number case UV muaj kev ruaj khov siab thiab tuaj yeem tswj tau qhov zoo ntawm daim duab thiab kev ruaj khov ntawm ntau qhov chaw ntev. Nws tiv taus cov teebmeem ntawm cov yam ntxwv sab nraud xws li UV rays, dej, kev hloov pauv thiab kev xeb ntawm cov tshuaj lom neeg, ua rau lub neej ntawm koj cov ntawv luam tawm ntev dua.
Ntau yam kev siv: UV number case siv tau rau kev luam ntawv ntawm ntau yam khoom siv, xws li iav, hlau, ceramics, plastics, ntoo, thiab lwm yam. Nws muaj kev nplaum zoo thiab kev hloov pauv mus rau ntau yam khoom siv thiab tuaj yeem ua tiav cov txiaj ntsig luam ntawv zoo.
Xim ci ntsa iab: Cov kua UV muaj peev xwm qhia xim zoo heev thiab tuaj yeem luam tawm cov duab ci ntsa iab. Nws ua rau muaj xim ntau dua thiab muaj ntau xim sib txawv, ua rau cov ntawv luam tawm pom tseeb dua.
Kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob: UV number case tsis muaj cov organic compounds volatile (VOC) thiab yuav tsis tso cov pa phem. Nws txoj kev kho kom tsis txhob muaj teeb meem huab cua ua rau los ntawm kev ua kom cov number case volatilization ib txwm muaj. Tsis tas li ntawd, tsis tas yuav tsum tau ua ntej cua sov thiab txias, txuag kev siv hluav taws xob.
Kev Sib Tov Tau: Cov kua UV muaj peev xwm sib sau ua ke, uas yog, nws tuaj yeem txau ntau zaus rau tib qho chaw kom tsim cov xim muaj zog thiab cov teebmeem peb-seem. Qhov no tso cai rau kev luam ntawv UV kom ua tiav cov teebmeem nplua nuj thiab ntau yam, xws li concave thiab convex, cov qauv zoo li tiag tiag, thiab lwm yam.
Feem ntau, kev siv UV number case tuaj yeem txhim kho kev luam ntawv zoo dua, ua kom cov khoom luam tawm ruaj khov dua, ua tiav kev siv dav dav thiab pom cov teebmeem pom zoo. Nws kuj yog ib qho kev xaiv zoo rau ib puag ncig thiab txuag hluav taws xob, uas ua raws li cov kev cai tiv thaiv ib puag ncig niaj hnub no.
