Cov khoom nqus UV
Nyob rau hauv lub hnub ci thiab fluorescence, cov yas thiab lwm yam khoom siv polymer raug kev cuam tshuam oxidation tsis siv neeg nyob rau hauv qhov kev ua ntawm ultraviolet rays, uas ua rau kev puas tsuaj ntawm cov polymers thiab kev puas tsuaj ntawm cov tsos thiab cov khoom siv kho tshuab. Tom qab ntxiv cov ultraviolet absorber, cov ultraviolet rays muaj zog heev tuaj yeem nqus tau thiab hloov mus ua lub zog tsis muaj teeb meem kom raug tso tawm lossis noj. Vim muaj ntau hom polymers, cov ultraviolet wavelengths uas ua rau lawv puas tsuaj kuj txawv. Cov ultraviolet absorbers sib txawv tuaj yeem nqus cov ultraviolet rays nrog cov wavelengths sib txawv. Thaum siv, cov ultraviolet absorbers yuav tsum tau xaiv raws li hom polymers.
Cov khoom nqus UV tuaj yeem muab faib ua cov hom hauv qab no raws li lawv cov qauv tshuaj lom neeg: salicylates, benzones, benzotriazoles, substituted acrylonitrile, triazine thiab lwm yam.
