ʻĀpana UV
Ma lalo o ka lā a me ka fluorescence, nā plastics a me nā mea polymer ʻē aʻe e loaʻa i ka hopena oxidation ma lalo o ka hana o nā kukuna ultraviolet, e alakaʻi ana i ka hōʻino ʻana o nā polymers a me ka hōʻino ʻana o ka helehelena a me nā waiwai mechanical. Ma hope o ka hoʻohui ʻia ʻana o ka ultraviolet absorber, hiki ke koho ʻia nā kukuna ultraviolet kiʻekiʻe a lilo i ikehu ʻino ʻole e hoʻokuʻu a ʻai ʻia. Ma muli o nā ʻano polymers like ʻole, ʻokoʻa nō hoʻi nā hawewe ultraviolet e hoʻohaʻahaʻa iā lākou. Hiki i nā mea hoʻoheheʻe ultraviolet ʻokoʻa ke komo i nā kukuna ultraviolet me nā lōʻihi hawewe like ʻole. I ka hoʻohana ʻana, pono e koho ʻia nā mea hoʻopili ultraviolet e like me nā ʻano polymers.
Hiki ke hoʻokaʻawale ʻia nā mea hoʻoheheʻe UV i kēia mau ʻano e like me ko lākou ʻano kemika: salicylates, benzones, benzotriazoles, acrylonitrile i hoʻololi ʻia, triazine a me nā mea ʻē aʻe.
