Bhodhoro uye inogona girazi inogona kunyatso cheka iyo ultraviolet ray, kudzivirira kuparara kwezviri mukati.Semuenzaniso, doro rinoiswa pachiedza chebhuruu kana chegirini chine wavelength isingasviki 550nm uye rinoburitsa kunhuhwirira, kunozivikanwa sekunaka kwezuva.Waini, muto uye zvimwe zvekudya zvichakanganiswawo nechiedza che ultraviolet nemhando isingasviki 250nm.Nyanzvi dzeGerman dzakakurudzira kuti mwenje unooneka wephotochemical chiito zvishoma nezvishoma unopera simba kubva kuchiedza chegirinhi kuenda kune kureba kwemafungu ekutungamira uye unopera panenge 520nm.Mune mamwe mazwi, 520nm ndiyo yakakosha wavelength, uye chero chiedza chipfupi pane icho chichaita kuti zviri mukati mebhodhoro zviparadzwe.Nekuda kweizvozvo, girazi rinogona kudikanwa kutora mwenje pazasi pe520nm, uye mabhodhoro ebrown anoshanda zvakanyanya.
Kana mukaka uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge mukaka mukaka, unoburitsa "chiedza chinonaka" uye "kunhuwa" nekuda kwekuumbwa kweperoxides uye kunotevera maitiro.Vitamin C uye ascorbic acid zvakare yakaderedzwa, sezvakaita mavhitamini A, Bg uye D. Mhedzisiro yechiedza pahutano hwemukaka inogona kudziviswa kana ultraviolet absorption ichiwedzerwa kune zvikamu zvegirazi, izvo zvisinganyanyi kuita ruvara uye kupenya.Kune mabhodhoro nemakani ane zvinodhaka, 2mm gobvu girazi rinodiwa kutora 98% yewavelength ye410nm uye kupfuura ne72% yewavelength ye700nm, iyo isingangodziviriri iyo photochemical effect, asi zvakare tarisa zviri mukati mebhodhoro.
Kunze kwegirazi requartz, yakawanda yakajairwa sodium-calcium-silicon girazi inogona kusefa yakawanda ultraviolet mwaranzi.Sodium-calcium-silicon girazi haigoni kupfuura nechiedza che ultraviolet (200 ~ 360nm), asi inogona kupfuura nechiedza chinooneka (360 ~ 1000nm), kureva kuti, girazi resodium-calcium-silicon rinogona kutora yakawanda ultraviolet rays.
Kuti usangane nezvinodiwa nevatengi zvekubuda pachena kwemabhodhoro egirazi, zviri nani kuita kuti girazi rebhodhoro rikwanise kutora ultraviolet ray uye kusaita rakasviba ruvara, wedzera iyo CeO mukuumbwa 2 inogona kusangana nezvinodiwa.Cerium inogona kuvapo seCe 3+ kana Ce 4+, ese ari maviri anogadzira kunyura kwakasimba kwe ultraviolet.Japanese patent inoshuma rudzi rwegirazi rakaumbwa rine vanadium oxide 0.01% ~ 1.0%, cerium oxide 0.05% ~ 0.5%.Mushure me ultraviolet irradiation, zvinotevera zvinoitika: Ce3++V3+ - Ce4++V2+
Nekuwedzerwa kwenguva yeradiation, iyo ultraviolet radiation dose yakawedzera, V2 + ratio yakawedzera, uye ruvara rwegirazi rwakadzika.Kana sake ichitambura ultraviolet irradiation kuti iparare nyore, inokanganisa kujeka negirazi bhodhoro remavara, zvisiri nyore kuona zvirimo.Gamuchira kuumbwa kunowedzera munhu CeO 2 uye V: O:, nguva yekuisa ipfupi, tambura ultraviolet irradiation dose kuti isave neruvara uye pachena kana ishoma, asi nguva yekuisa irefu, ultraviolet irradiation dose yakawandisa, girazi kushanduka, pfuura kudzika kwe. discoloration, inogona kutonga kureba kwedhipoziti nguva.
