icapiro rya UV ni uburyo bwihariye bwoicapiro rya elegitoronikigukoresha urumuri rwa ultraviolet (UV) mu kumisha cyangwa gukosora wino, kole cyangwa irangi hafi ya byose bikimara kugera ku mpapuro, cyangwa aluminiyumu, ifuro cyangwa acrylic - mu by'ukuri, igihe cyose bihuye n'icyuma gicapa, ubwo buryo bushobora gukoreshwa mu gucapa hafi ya byose.
Uburyo bwo gukaraba inzara hakoreshejwe imirasire ya UV – uburyo bwo kumisha hakoreshejwe ikoranabuhanga rya photochemical – bwatangijwe bwa mbere nk'uburyo bwo kumisha vuba amenyo ya gel akoreshwa mu gutunganya inzara, ariko vuba aha bwakoreshejwe n'inganda zicapa aho bukoreshwa mu gucapa ku kintu cyose kuva ku byapa n'udutabo kugeza ku macupa y'inzoga. Uburyo ni bumwe n'uburyo bwo gucapa gakondo, itandukaniro ryonyine ni irangi rikoreshwa n'uburyo bwo kumisha – hamwe n'ibicuruzwa byiza bikorerwamo.
Mu icapiro risanzwe, inyito zishongesha zikoreshwa; izi zishobora gushonga no kurekura ibintu bihumanya ikirere (VOCs) byangiza ibidukikije. Ubu buryo bunatanga ubushyuhe n'impumuro mbi. Byongeye kandi, bisaba ifu y'inyongera kugira ngo ifashe mu gikorwa cyo kugabanya no kumisha inyito, bishobora gufata iminsi myinshi. Inyito zinjira mu cyuma cyo gucapa, bityo amabara ashobora gusa n'aho yakuweho kandi agashira. Igikorwa cyo gucapa gikoreshwa ahanini mu byuma by'impapuro n'amakarita, bityo ntigishobora gukoreshwa ku bikoresho nka pulasitiki, ikirahure, icyuma, impapuro cyangwa acrylic nka UV printing.
Mu icapiro rya UV, amatara ya mercure/quartz cyangwa LED akoreshwa mu gukangura aho gukoresha ubushyuhe; urumuri rwa UV rufite imbaraga nyinshi rukurikira neza iyo wino yihariye ikwirakwijwe ku cyuma gicapura, ikayumisha ikimara gushyirwaho. Kubera ko wino ihinduka kuva ku kintu gikomeye cyangwa ifu ikajya ku mazi ako kanya, nta mahirwe yo gushonga bityo nta VOC, imyuka y’uburozi cyangwa ozone bisohoka, bigatuma ikoranabuhanga ritangiza ibidukikije aho ritagaragaza neza karubone.
Wino, kole cyangwa irangi rigizwe n'uruvange rwa monomer z'amazi, oligomer - polymer zigizwe n'ibice bike bisubiramo - na fotoinitiators. Mu gihe cyo gucukura, urumuri rwinshi mu gice cya ultraviolet cya spectrum, gifite uburebure buri hagati ya 200 na 400 nm, rwinjizwa na fotoinitiator inyura mu buryo bwa chemical - chemical cross linking - bigatuma wino, kole cyangwa kole bikomera ako kanya.
Biroroshye kubona impamvu icapiro rya UV ryarenze ubuhanga busanzwe bwo kumisha hakoreshejwe amazi n'ubushyuhe, ndetse n'impamvu byitezwe ko rizakomeza gukundwa. Ntabwo ubu buryo bwihutisha umusaruro gusa - bivuze ko hakorwa byinshi mu gihe gito - igipimo cyo kwangwa kiragabanuka kuko ubuziranenge buri hejuru. Ibitonyanga by'iwino bitose birakurwaho, bityo nta gushwanyagurika cyangwa gushonga, kandi uko kumisha biba hafi ako kanya, nta mwuka uhinduka bityo nta gutakaza ubunini cyangwa ingano y'igitambaro. Ibisobanuro bito birashoboka, kandi amabara arasobanutse neza kandi aragaragara neza kuko nta kwinjiza mu cyuma cyo gucapa: guhitamo icapiro rya UV aho gukoresha uburyo busanzwe bwo gucapa bishobora kuba itandukaniro hagati yo gukora ikintu cy'agaciro, n'ikintu gisa nkaho kitari cyiza cyane.
Wino kandi ifite imiterere myiza y’umubiri, irangi ryiza ry’urumuri, irangi ryiza, irangi rirwanya imiti, irangi rishongesha kandi rikagira ubukana bwiza, kandi irangi rirushaho gukomera. Nanone kandi riramba kandi rirwanya ikirere, kandi ritanga ubudahangarwa bwo kwiyongera ku gucika intege, bigatuma riba ryiza cyane ku byapa byo hanze. Iyi gahunda kandi ihendutse - ibicuruzwa byinshi bishobora gucapwa mu gihe gito, ku bwiza bwiza kandi bikananirana bike. Kubura kwa VOC bisohora hafi ya byose bivuze ko hari ibyangiritse bike ku bidukikije kandi iyo gahunda irarambye.
