Ibhotile kunye neglasi inokunqumla ngokufanelekileyo imitha ye-ultraviolet, ithintele ukuwohloka kwezinto eziqulethweyo.Umzekelo, ibhiya ibonakaliswe kukukhanya okuluhlaza okwesibhakabhaka okanye okuluhlaza kunye nobude obungaphantsi kwe-550nm kwaye iya kuvelisa ivumba, elaziwa ngokuba yincasa yelanga.Iwayini, i-sauce kunye nokunye ukutya kuya kuchaphazeleka kukukhanya kwe-ultraviolet kunye nomgangatho ongaphantsi kwe-250nm.Abaphengululi baseJamani bacebise ukuba intshukumo yokukhanya okubonakalayo ye-photochemical iyancipha ngokuthe ngcembe ukusuka ekukhanyeni okuluhlaza ukuya kwicala elide kwaye iphele malunga ne-520nm.Ngamanye amazwi, i-520nm bubude obubalulekileyo, kwaye nakuphi na ukukhanya okufutshane kunoko kuya kubangela ukuba imixholo yebhotile itshatyalaliswe.Ngenxa yoko, ngaba iglasi iyafuneka ukufunxa ukukhanya okungaphantsi kwe-520nm, kwaye iibhotile ezimdaka zisebenza kakuhle.
Xa ubisi lubonakaliswe ekukhanyeni, luvelisa "incasa elula" kunye "nevumba" ngenxa yokubunjwa kweperoxides kunye nokuphendula okulandelayo.I-Vitamin C kunye ne-ascorbic acid nayo iyancitshiswa, njengoko i-vitamin A, Bg kunye no-D. Umphumo wokukhanya kumgangatho wobisi unokuphetshwa ukuba ukuxutywa kwe-ultraviolet yongezwa kumacandelo eglasi, anempembelelo encinci kumbala kunye ne-luster.Kwiibhotile kunye neetoti eziqulethe iziyobisi, i-2mm yeglasi enzima iyadingeka ukuba ithathe i-98% ye-wavelength ye-410nm kwaye idlule kwi-72% ye-wavelength ye-700nm, engenakunqanda kuphela umphumo we-photochemical, kodwa iphinde ibone imixholo yebhotile.
Ngaphandle kweglasi yequartz, eyona glasi iqhelekileyo yesodium-calcium-silicon inokucoca imitha ye-ultraviolet.Iglasi ye-sodium-calcium-silicon ayinakudlula ekukhanyeni kwe-ultraviolet (200 ~ 360nm), kodwa inokudlula ekukhanyeni okubonakalayo (360 ~ 1000nm), oko kukuthi, iglasi eqhelekileyo ye-sodium-calcium-silicon inokufunxa imisebe emininzi ye-ultraviolet.
Ukuze kuhlangatyezwane nemfuno yabathengi yokubonakala kweebhotile zeglasi, kungcono ukwenza iglasi yebhotile ikwazi ukufunxa i-ultraviolet ray kwaye ingenzi umbala wayo omnyama, yongeza i-CeO ekubunjweni kwe-2 inokuhlangabezana nemfuneko.I-Cerium ingaba khona njenge-Ce 3+ okanye i-Ce 4+, zombini ezivelisa ukufunxa okunamandla kwe-ultraviolet.I-patent yaseJapan ibika uhlobo lokwakheka kweglasi equlethe i-vanadium oxide 0.01% ~ 1.0%, i-cerium oxide 0.05% ~ 0.5%.Emva kokukhanya kwe-ultraviolet, oku kulandelayo kwenzeka: Ce3++V3+ - Ce4++V2+
Ngokwandiswa kwexesha lokukhanya, idosi yemitha ye-ultraviolet yanda, umlinganiselo we-V2 + unyukile, kwaye umbala weglasi uye waba nzulu.Ukuba i-sake inengxaki ye-ultraviolet irradiation ukuba itshabalale ngokulula, ichaphazela ukungafihli kunye nebhotile yeglasi enemibala, akukho lula ukujonga umxholo.Yamkela ukwakheka okongeza umntu i-CeO 2 kunye ne-V: O:, ixesha lokufaka idiphozithi lifutshane, i-ultraviolet irradiation ithamo ukuba ingabi mbala kwaye ibonakale xa incinci, kodwa ixesha lokufaka idiphozithi lide, idosi ye-ultraviolet irradiation igqithise, i-glass discoloration, idlula ubunzulu Ukutshintsha kombala, kunokugweba ubude bexesha lediphozithi.
