Hiki i ka ʻōmole a me ke aniani ke ʻoki pono i ka hihi ultraviolet, pale i ka hōʻino ʻana o nā mea i loko.No ka laʻana, ʻike ʻia ka pia i ke kukui uliuli a i ʻole ka ʻōmaʻomaʻo me ka haʻahaʻa haʻahaʻa ma lalo o 550nm a e hoʻopuka i kahi ʻala, i kapa ʻia ʻo ka ʻono o ka lā.ʻO ka waina, ka ʻai a me nā meaʻai ʻē aʻe e hoʻopilikia ʻia e ke kukui ultraviolet me ka maikaʻi o lalo o 250nm.Manaʻo ka poʻe akamai Kelemania e hoʻonāwaliwali mālie ka hana photochemical o ke kukui ʻike ʻia mai ke kukui ʻōmaʻomaʻo a hiki i ke ala nalu lōʻihi a pau ma kahi o 520nm.I nā huaʻōlelo ʻē aʻe, ʻo 520nm ka lōʻihi hawewe koʻikoʻi, a ʻo nā kukui ʻoi aku ka pōkole ma mua o kēlā e hoʻopau ʻia nā mea o ka hue.ʻO ka hopena, pono ke aniani e komo i ka mālamalama ma lalo o 520nm, a ʻoi aku ka maikaʻi o nā hue ʻeleʻele.
Ke ʻike ʻia ka waiū i ka mālamalama, hoʻopuka ia i ka "ʻono māmā" a me ka "ʻala" ma muli o ka hoʻokumu ʻana o nā peroxides a me nā hopena hope.Hoʻemi pū ʻia ka Vitamin C a me ka waikawa ascorbic, e like me nā huaora A, Bg a me D. Hiki ke pale ʻia ka hopena o ka mālamalama i ka maikaʻi o ka waiū inā hoʻohui ʻia ka absorption ultraviolet i nā mea aniani, ʻaʻohe hopena liʻiliʻi i ke kala a me ka lustre.No nā ʻōmole a me nā kini i loaʻa i nā lāʻau lapaʻau, koi ʻia ke aniani mānoanoa 2mm e komo i ka 98% o ka lōʻihi o ka nalu o 410nm a hele i 72% o ka lōʻihi o ka nalu o 700nm, ʻaʻole hiki ke pale wale i ka hopena photochemical, akā nānā pū i nā mea o ka hue.
Ma waho aʻe o ke aniani quartz, hiki i ke aniani sodium-calcium-silicone ke kānana i nā kukuna ultraviolet.ʻAʻole hiki i ke aniani sodium-calcium-silicon ke hele i ke kukui ultraviolet (200 ~ 360nm), akā hiki ke hele i ke kukui ʻike ʻia (360 ~ 1000nm), ʻo ia hoʻi, hiki i ke aniani sodium-calcium-siliconi maʻamau ke komo i ka hapa nui o nā kukui ultraviolet.
I mea e hoʻokō ai i ka koi o ka mea kūʻai aku no ka ʻike maopopo ʻana o nā hue aniani, ʻoi aku ka maikaʻi o ka hana ʻana i ke aniani ʻōmole hiki ke hoʻomoʻi i ka hihi ultraviolet a ʻaʻole e hana i kona kala ʻeleʻele, hoʻohui i ka CeO i ka haku mele 2 hiki ke hoʻokō i ke koi.Hiki ke noho ʻo Cerium ma ke ʻano he Ce 3+ a i ʻole Ce 4+, ʻo ia mau mea ʻelua e hoʻopuka i ka absorption ultraviolet ikaika.Hōʻike ka patent Kepani i kahi ʻano o ke aniani i loaʻa ka vanadium oxide 0.01% ~ 1.0%, cerium oxide 0.05% ~ 0.5%.Ma hope o ka ultraviolet irradiation, hiki mai kēia mau hopena: Ce3++V3+ - Ce4++V2+
Me ka hoʻolōʻihi ʻia o ka manawa irradiation, hoʻonui ka nui o ka radiation ultraviolet, hoʻonui ʻia ka ratio V2+, a hohonu ka kala aniani.Inā pilikia ka sake i ka ultraviolet irradiation e palaho maʻalahi, e hoʻopili i ke aniani me ka ʻōmole aniani kala, ʻaʻole maʻalahi ke nānā i ka ʻike.E hoʻokomo i ka haku mele e hoʻohui i ke kanaka CeO 2 a me V: O:, pōkole ka manawa waiho, e ʻae i ka nui o ka ultraviolet irradiation ʻaʻole waihoʻoluʻu a ʻike ʻole i ka wā liʻiliʻi, akā lōʻihi ka manawa waiho, ʻoi aku ka nui o ka nui o ka ultraviolet, ʻeleʻele ke aniani, hele i ka hohonu o ka. discoloration, hiki ke hoʻoholo i ka lōʻihi o ka waiho manawa.
