mai sha UV
A ƙarƙashin hasken rana da hasken rana, robobi da sauran kayan polymer suna fuskantar amsawar iskar shaka ta atomatik a ƙarƙashin tasirin hasken ultraviolet, wanda ke haifar da lalacewar polymers da lalacewar bayyanar da halayen injiniya. Bayan an ƙara mai ɗaukar ultraviolet, ana iya sha hasken ultraviolet mai ƙarfi sosai kuma a mayar da shi makamashi mara lahani don a sake shi ko a cinye shi. Saboda nau'ikan polymers daban-daban, raƙuman ultraviolet da ke lalata su suma sun bambanta. Masu ɗaukar ultraviolet daban-daban na iya sha hasken ultraviolet tare da raƙuman haske daban-daban. Lokacin amfani, ya kamata a zaɓi masu ɗaukar ultraviolet bisa ga nau'ikan polymers.
Ana iya raba masu shaƙar UV zuwa nau'ikan masu zuwa bisa ga tsarin sinadaransu: salicylates, benzones, benzotriazoles, acrylonitrile da aka maye gurbinsu, triazine da sauransu.
