Izibane zokunyanga zeUV eziphathwa ngesandla zizixhobo ezisebenzisa imitha ye-ultraviolet (UV) ukubangela ukusabela kweekhemikhali, ukunyanga ngokukhawuleza iileyiti, izinto zokuncamathelisa, okanye ii-inki. Umgaqo wabo ongundoqo wokusebenza kukusabela kweefotochemical: imitha ye-UV yobude obuthile buvuyisa i-photoinitiator, ethi yona ibangele ukuba ii-monomers okanye ii-oligomers kwizinto eziphathekayo zenziwe i-polymerize okanye i-crosslink, ekugqibeleni yenze i-coating eqinile.
Ezi zixhobo zihlala zisebenzisa izibane zomphunga zemercury okanye imithombo yokukhanya ye-LED, enezibane zomphunga zemercury zisetyenziswa ngokubanzi ngenxa yokusebenza kwazo okuphezulu kwe-UV. Xa yangoku idlula kumphunga wemekyuri ngaphakathi kwesibane, iiathom zemercury ziyavuya ukuya kwimo ephezulu-yamandla. Emva koko batshintshela kumhlaba ophantsi kwaye bakhuphe imitha ye-UV enamaza amaza agxile kwi-365nm (UVA), 385nm, okanye i-405nm. La maza amaza e-UV asebenze ngokufanelekileyo ii-photoinitiators (ezifana ne-benzophenone okanye i-benzoin ether), zibangele ukuba zibole kwaye zenze ii-radicals zamahhala okanye ii-cations, ezithi nazo ziqalise i-polymerization yezinto ze-resin.
Izibane zokunyanga ze-UV eziphathwa ngesandla ziyilelwe ukuphatheka kunye nolawulo oluchanekileyo, zihlala zinokukhutshwa kwamandla ahlengahlengiswayo kunye nexesha lokuvezwa ukuze zihambelane neemfuno zokunyanga izixhobo ezahlukeneyo. Umzekelo, -imowudi ephantsi ilungele iileya ezibhityileyo, ngelixa imowudi ephezulu{2}}yobunzulu isetyenziselwa ukunyanga iileya ezishinyeneyo ngokukhawuleza. Ngaphaya koko, izibane zale mihla ze-LED zokunyanga ze-UV ziya zithatha indawo yezibane zemercury zemveli ngenxa yokusebenzisa amandla aphantsi, ubomi obude, kunye nokusebenza simahla imekyuri. Nangona kunjalo, uluhlu lwabo olumxinwa lwamaza lufuna iinkqubo ezithile zefotoinitiator.
Ngexesha lenkqubo yesicelo, umqhubi kufuneka aqinisekise ukuba ukukhanya kwe-UV kukhanyisa ngokulinganayo umphezulu ukuze unyangeke ukuphepha izithunzi okanye ukuvuza okukhanyayo okunokukhokelela ekunyangeni okungaphelelanga. Ngaphaya koko, ngenxa yokuba ukukhanya kwe-UV kuyingozi kulusu lomntu kunye namehlo, izixhobo zihlala zibandakanya iindlela zokhuseleko ezinjengeealam ezinexesha okanye izihluzi zamehlo.
Isishwankathelo, izibane zokunyanga ze-UV eziphathwa ngesandla, ngokulawula ngokuchanekileyo imitha ye-UV kunye nezixhobo zokunyanga ngokufanelekileyo, zisetyenziswa ngokubanzi kwizicelo ezinje ngendibano ye-elektroniki, ukubuyiselwa kwamazinyo, kunye neengubo zemizi-mveliso. Inkqubela phambili yetekhnoloji eqhubekayo iqhuba uphuhliso lwemveliso ekhawulezileyo kunye nokulungiswa.
