UV absorber
Nyob rau hauv tshav ntuj thiab fluorescence, plastics thiab lwm yam ntaub ntawv polymer raug oxidation tsis siv neeg cov tshuaj tiv thaiv nyob rau hauv qhov kev txiav txim ntawm ultraviolet rays, uas ua rau degradation ntawm polymers thiab deterioration ntawm tsos thiab txhua yam khoom. Tom qab ntxiv ultraviolet absorber, lub siab-zog ultraviolet rays tuaj yeem raug xaiv absorbed thiab hloov mus rau hauv lub zog tsis muaj teeb meem kom tso tawm lossis noj. Vim muaj ntau hom polymers, ultraviolet wavelengths uas degrade lawv kuj txawv. Txawv ultraviolet absorbers tuaj yeem nqus tau cov kab hluav taws xob ultraviolet nrog cov wavelength sib txawv. Thaum siv, ultraviolet absorbers yuav tsum tau xaiv raws li hom polymers.
UV absorbers tuaj yeem muab faib ua hom hauv qab no raws li lawv cov qauv tshuaj: salicylates, benzones, benzotriazoles, hloov acrylonitrile, triazine thiab lwm yam.
