Umgaqo wokunyanga we-UVLED

Into ebizwa ngokuba yi-UVLED yokunyanga kukongeza izizathu zokukhanya kwi-resin kwifomula ekhethekileyo. Emva kokufunxa ukukhanya okuphakamileyo kwe-ultraviolet kwisixhobo sokunyanga se-UVLED, i-radicals yamahhala esebenzayo okanye iziseko ze-ion ziyenziwa, ezibangela ukuhlanganiswa, ukudibanisa kunye namasebe ukuba aphendule, ukwenzela ukuba i-resin reactor yenza i-resin (ipeyinti ye-UV, inki, i-adhesive, njalo njalo) ukusuka kulwelo ukuya kwimeko eqinileyo kwimizuzwana embalwa. Iimpawu ezibonakalayo zezixhobo zokunyanga ze-UVLED zichatshazelwa ngokuyimfuneko ngoomatshini bokunyanga be-UV -optical. Ukusebenza okulindelekileyo, nokuba ikhusela iglue, inki, okanye i-adhesive, iya kuxhomekeka kwiiparamitha, ukuyila kunye neendlela zokulawula ii-chips ze-LED kule mishini yokunyanga. Iiparamitha ezine eziphambili zetshiphu ye-LED zezi: 1.UV imitha (okanye ingxinano) 2. usasazo olubonakalayo (ubude bobude) 3. Imitha (okanye amandla eUV) 4. Ubushushu bemitha bunxulumene nemitha enkulu okanye umthamo wemitha, kwaye ezahlukeneyo, kunye ezahlukeneyo UVLED spectrum, inki kunye neglu ekhuselayo iya kubonisa iimpawu ezahlukeneyo kakhulu. Ukukwazi ukuchonga iimpawu ezahlukeneyo ze-chip ze-LED kunye nokuzenza zihambelane neempawu zamehlo zezinto zokunyanga, kunye nokwandisa umda wokuqiniswa kwe-UVLED njengenkqubo yokuvelisa ekhawulezayo nesebenzayo. Kukho iipropathi ezininzi ze-optical kunye nezomzimba zenkqubo yokunyanga echaphazela umphumo wokuqina, okhokelela kumahluko kwimbonakalo yeempawu ze-UV zokunyanga. Impembelelo yeeparamitha ezinxulumeneyo kumgangatho wokunyanga we-UV 1. Ubude bobude bomatshini we-UVLED: I-spectrum ye-365nm band ifanelekile kwi-inki yokunyanga eqhelekileyo (ayifanelekanga kwi-inki efunwa yi-spectrals ekhethekileyo enjengeentyatyambo zomkhenkce kunye nemibimbi). Abanye oomatshini be-UV baninzi kakhulu ngenxa yempembelelo ye-chip ye-LED, eya kuchaphazela ukukhanya okuqinileyo. Kucetyiswa ukuba abathengi baqhube uvavanyo oluluqilima olukhanyayo xa bekhetha izixhobo zokulungisa izibane ze-UV ukuvavanya ukuba ubude bamaza omatshini we-UV buhlangabezana neemfuno eziqinileyo zokukhanya. 2. Amandla omatshini we-UVLED: Ngokuqhelekileyo, amandla afunwa yi-UV optical inki yi-80-120MW / CM, kwaye amandla okukhanya okufunxayo malunga ne-2000 3000mJ / cm. Amandla okukhanya agqithisileyo anokubangela ukuba i-inki ibe brittleness. Ukukhanya okuphantsi-okuphantsi umphumo oqinileyo. Umzekelo wokusetyenziswa kwemitha yemitha ye-UV iyafana nokukhanya okubonakalayo, zonke zinomgca, kodwa amandla azo okungena akabonakali kangako. Okukhona ubude bamaza bufutshane, kokukhona kusiba mbi ngakumbi amandla agqobhozayo. Ukunyanga kwangaphakathi kunye nokudluliselwa kokukhanya okungcono. 1. Isibane se-UV sivelisa i-UV ngelixa sivelisa ukufudumeza kwemitha ye-IR ethile. Le fiva yemitha iluncedo kwizinto zokusebenza ezinobushushu obuncinci. Kulindeleke ukuba umphumo ubonakale ngakumbi. Umzekelo wesicelo: Ipeyinti ye-UV yemigangatho yokhuni, iimveliso zetsimbi, njl.; Iingubo ze-UV zokugquma kwiibhodi zeesekethe eziprintiweyo; Iglu ye-UV kwiimveliso zeglasi. 2. Impembelelo kwiqondo lobushushu inovakalelo ngakumbi okanye iindawo zekhemikhali ezixhathisa ubushushu ezinokumelana nobushushu obuhlwempuzekileyo. Ukunciphisa i-IR radiation thermal yenye yezihloko zokusika zezixhobo zokunyanga ze-UV kumazwe ahlukeneyo kwihlabathi. Ngokuqhelekileyo, isetyenziselwa ukusebenzisa ukupholisa kwamanzi, ukubonakalisa, ukuhluza rhoqo kunye nezinye iindlela. Isonjululwe, kodwa ixabiso lilanga le-ultraviolet elimele lilahleke. Imizekelo yesicelo: IiPVC ezahlukeneyo (ezifana namakhadi e-IC), ifilimu yeplastiki, i-Ke (i-outlet) yokushicilela ioli ye-UV, ukuprintwa okukhethekileyo kwephepha (intyatyambo yomkhenkce), ukuprintwa kwekhibhodi yekhompyutha.
