Kev tiv thaiv ultraviolet (UV) kev ua tau zoo yog qhov tseem ceeb ntawm cov qhov rooj niaj hnub thiab qhov rais, ua rau lub neej ntev ntawm cov rooj tog zaum sab hauv thiab kev nplij siab ntawm cov neeg nyob. UV hluav taws xob tuaj yeem ua rau muaj kev puas tsuaj loj, suav nrog fading thiab deterioration ntawm rooj tog, flooring, thiab artwork, nrog rau ua rau muaj kev phom sij rau cov neeg nyob hauv lub sijhawm ntev.
Txhawm rau daws cov teeb meem no, cov tuam txhab tsim cov thev naus laus zis glazing rau hauv lawv cov khoom. Low-emissivity (Low-E) iav, coated nrog microscopically nyias txheej ntawm hlau oxide, qhia txog ntau npaum li cas ntawm UV rays thaum tso cai rau pom lub teeb hla dhau. Cov thev naus laus zis no tsis tsuas yog txhim kho UV tiv thaiv tab sis kuj tseem txhim kho cov rwb thaiv tsev thermal, txo kev siv hluav taws xob rau cua sov thiab cua txias.
Laminated iav, ua los ntawm sandwiching ib txheej ntawm polyvinyl butyral (PVB) ntawm ob lub iav iav, muab kev tiv thaiv UV zoo heev. PVB txheej thaiv txog li 99% ntawm UV rays, muab kev tiv thaiv zoo tshaj plaws rau sab hauv.
Cov yeeb yaj kiab qhov rai kuj tuaj yeem siv rau cov qhov rais uas twb muaj lawm los txhim kho UV tiv thaiv. Cov yeeb yaj kiab no yog tsim los lim tawm qhov teeb meem UV hluav taws xob yam tsis muaj kev cuam tshuam rau kev pom lossis kev sib kis ntawm lub teeb.
Kev ntsuas kev tiv thaiv UV ntawm lub qhov rooj thiab qhov rais suav nrog kev sim cov thev naus laus zis no nyob rau hauv ntau yam xwm txheej kom ntseeg tau tias lawv muaj kev tiv thaiv zoo tiv thaiv UV hluav taws xob, yog li tiv thaiv qhov chaw sab hauv thiab txhim kho cov kav ntev thiab kev nplij siab ntawm lub tsev.
