Mbere na mbere, amabara yo mu mazi (ashingiye ku mazi) na UV yakoreshejwe cyane mu nganda z’ubugeni bw’amashusho nk’amabara yo hejuru ahanganye. Yombi atuma ubwiza n’uburinzi birushaho kwiyongera, byongerera agaciro ibicuruzwa bitandukanye byacapwe.
Itandukaniro mu buryo bwo kuvura
Mu by’ukuri, uburyo bwo kumisha cyangwa gukamura ibintu byombi buratandukanye. Irangi ry’amazi rirakama iyo ibice by’irangi bihinduka umwuka (nk’amazi agera kuri 60%) bihatiwe gushonga cyangwa bigashyirwa mu gice cy’amazi gifite imyenge. Ibi bituma ibintu bikomeye by’irangi bihurira hamwe bigakora agace gato, k’umusemburo w’amazi.
Itandukaniro ni uko irangi rya UV rikorwa hakoreshejwe ibice 100% by'amazi akomeye (adafite umuyaga uhindagurika) bivura cyangwa bigahindura imiterere y'amazi mu buryo bukoresha ingufu nke iyo bihuye n'urumuri rwinshi rwa ultraviolet (UV). Uburyo bwo gukosora butera impinduka zihuse, bigatuma amazi ahinduka ibintu bikomeye ako kanya (cross-linking) bigatera icyuma gikomeye cyumye.
Itandukaniro mu bikoresho byo gukoresha
Ku bijyanye n'ibikoresho byo gukoresha, irangi ry'amazi ridafite viscosity nyinshi cyangwa UV rishobora gukoreshwa neza hakoreshejwe ink ya nyuma mu gucapa ink ya flexo na gravure liquid. Ibinyuranye n'ibyo, irangi ry'ink rya web na sheet-fed offset litho paste risaba ko hongerwamo irangi rikoreshwa mu gukanda kugira ngo hashyirweho irangi ry'amazi ridafite viscosity nyinshi cyangwa UV ridafite viscosity nyinshi. Irangi ry'inyuma naryo rikoreshwa mu gushyiramo irangi ry'ink ya UV.
Imashini zicapa za Flexo na gravure zifite ubushobozi bwo kumisha wino n'amazi byamaze gushyirwaho kugira ngo zumishe neza irangi ry'amazi. Uburyo bwo gucapa bushyuha bwa Web offset nabwo bwagaragaye ko bufite ubushobozi bwo kumisha irangi ry'amazi. Ariko, ni ikindi kibazo iyo utekereje uburyo bwo gucapa irangi ry'amazi ritangwa n'amashuka. Aha gukoresha irangi ry'amazi bisaba gushyiraho ibikoresho byihariye byo kumisha bigizwe n'ibikoresho bitanga umwuka wa infrared, ibyuma bishyushye, n'ibikoresho bikura umwuka.
Itandukaniro mu gihe cyo kumisha
Gutanga igihe kirekire nabyo birasabwa kugira ngo hatangwe igihe cy'inyongera cyo kumisha. Iyo utekereje ku kumisha (gutunganya) irangi rya UV cyangwa wino, itandukaniro riri mu bwoko bw'ibikoresho byihariye byo kumisha (gutunganya) bikenewe. Sisitemu zo kumisha UV zitanga cyane cyane urumuri rwa UV rutangwa n'amatara ya mercury arc arc y'umuvuduko uringaniye, cyangwa amasoko ya LED afite ubushobozi buhagije bwo kumisha neza ku muvuduko ukenewe.
Irangi ry'amazi riguma ryumutse vuba kandi hagomba kwitabwaho gusukurwa mu gihe cyose irangi rihagaze. Itandukaniro ni uko irangi ry'imirasire ya UV riguma rifunguye igihe cyose hatabayeho urumuri rwa UV. Irangi rya UV, irangi, na varnish ntibituma uturemangingo twa anilox twuma cyangwa ngo bizibe. Nta mpamvu yo gusukura hagati yo gukoresha irangi cyangwa mu mpera z'icyumweru, bigabanye igihe cyo kuruhuka no gutakaza.
Irangi ry’amazi n’iry’imirasire ya UV byombi bishobora gutanga urumuri rwinshi, ndetse n’irangi ry’uburyo butandukanye kuva ku mucyo mwinshi, kugeza kuri satin kugeza kuri matte. Itandukaniro ni uko irangi rya UV rishobora gutanga irangi ry’imirasire ry’imirasire ry’imirasire ry’imirasire rigaragara neza.
Itandukaniro mu gusiga
Irangi ry’amazi muri rusange ritanga ubushobozi bwo kwirinda gushonga, gushonga, no gukumira. Ibikoresho byakozwe mu buryo bwihariye bishobora no gutanga uburinzi ku mavuta, alkali, alkali, no kurinda amazi. Itandukaniro ni uko irangi ry’imirasire ya UV rikunze gutera intambwe irenga, ritanga ubushobozi bwo kurwanya gushonga, gushonga, gufunga, imiti, no gukumira ibicuruzwa.
Irangi ry’amazi rya thermoplastic ryakoreshejwe mu gupfuka amabati ryakozwe kugira ngo rifate amazi mu buryo bunyura mu ibara ry’umusemburo usanzwe unyura mu ibara ry’umusemburo rituma wino yumuka buhoro buhoro, bigabanyiriza cyangwa bigakuraho ifu ikoreshwa mu gukumira ko wino ihindagurika. Ubushyuhe bw’ibirundo bugomba kuguma kuri dogere 85-95®F kugira ngo hirindwe ko irangi ryumye rigabanuka ku bushyuhe bwinshi, kandi rigashobora guhagarara no kuziba. Icyiza ni uko umusaruro urushaho kwiyongera kuko impapuro zipfutse zishobora gutunganywa vuba.
Itandukaniro ni uko irangi rya UV rishyirwa ku murongo rikoresheje irangi ritose hejuru ya wino ya UV byombi bivurwa mu gihe cyo gukanda, kandi impapuro zishobora gukomeza gutunganywa ako kanya. Iyo irangi rya UV rikoreshejwe irangi risanzwe rya litho rifatwa nk'iry'amazi, irasabwa gufunga no gufata kuri wino kugira ngo ribe ishingiro ry'irangi rya UV. Irangi rya UV/risanzwe rishobora gukoreshwa kugira ngo hatagira irangi rikoreshwa.
Ingaruka ku bantu, ibiryo n'ibidukikije
Irangi ry'amazi ritanga umwuka mwiza, VOC nkeya, alcool nta, impumuro nkeya, ntirishobora gushya, ntirihumanya, kandi ntirihumanya. Mu buryo nk'ubwo, irangi ry'imirasire ya UV 100% ntiritanga imyuka ihumanya, VOC nta na imwe, kandi ntirishobora gushya. Itandukaniro ni uko irangi ry'imirasire ya UV ritose ridafite umuti rigizwe n'ibintu bishobora kugira impumuro ikarishye, kandi bishobora kuva ku bito kugeza ku bikomeye nk'ibintu bishobora gutera ubwivumbure, bishobora gutera allergie ku bantu bamwe na bamwe. Ku ruhu no mu maso bigomba kwirindwa. Mu buryo bwiza, irangi ry'imirasire ya UV rifatwa nk'"Ikoranabuhanga Rigezweho ryo Kugenzura" (BACT) na EPA, rigabanya irangi ry'imirasire ya VOC, CO2, n'ingufu zisabwa.
Ingufu zo mu mazi zishobora guhinduka mu buryo buhamye mu gihe cyose cyo gukanda bitewe n’ibyuka ry’ingufu, hamwe n’ingaruka za Ph. Itandukaniro ni 100% by’ibintu bikomeye bya UV bigumana uburyo buhamye mu gihe cyose nta rumuri rwa UV rubaho.
Irangi ryumye ry’amazi rishobora kongera gukoreshwa, kubora no kongera gukoreshwa. Itandukaniro ni uko mu gihe irangi rya UV ryavuwe rishobora kongera gukoreshwa no kongera gukoreshwa, ariko ritinda kubora. Ibi biterwa n’uko ibice by’irangi bihuza ibyuma,
bitanga ubushobozi bwo kurwanya ibinyabutabire mu buryo bukabije ndetse no mu buryo bwa shimi.
Irangi ry'amazi rirakama rikagira amazi meza nta muhondo ujyanye n'igihe. Itandukaniro ni uko irangi ry'imirasire ya UV ryavuwe rishobora no kugaragaza ubwiza bwinshi, ariko hagomba kwitonderwa mu gukora irangi kuko bimwe mu bikoresho fatizo bishobora gutuma irangi ry'umuhondo.
Ibyuma bitwikiriye amazi bishobora kubahiriza amabwiriza ya FDA ku biryo byumye cyangwa/cyangwa ibiryo bitose. Itandukaniro ni uko ibyuma bitwikiriye UV, usibye imiterere mike cyane, ntibishobora kubahiriza amabwiriza ya FDA ku biryo byumye cyangwa bitose/bifite amavuta.
Ibyiza
Uretse itandukaniro, irangi ry’amazi n’iry’imirasire ya UV risangiye inyungu nyinshi ku rugero rutandukanye. Urugero, imiterere yihariye ishobora gutanga ubushyuhe, amavuta, alkali, alkali, n’ubushuhe. Byongeye kandi, ishobora gutanga ubushobozi bwo kwirinda gukurura cyangwa kole, uburyo butandukanye bwa COF, ubushobozi bwo gushushanya, kwemerwa kw’urupapuro rushyushye cyangwa rukonje, ubushobozi bwo kurinda inki z’icyuma, kongera umusaruro, gutunganya mu murongo, ubushobozi bwo gukora no guhindukira, kuzigama ingufu, kudatangira, no gukuraho ifu ya spray mu buryo butunguranye.
Ubucuruzi bwacu muri Cork Industries ni uguteza imbere no gukora irangi ryihariye rya Aqueous, Ultraviolet-curing energy (UV), na Electron Beam (EB). Cork ikura neza kubera ubushobozi bwayo bwo gukora ibikoresho bishya kandi by'ingirakamaro biha imashini itunganya amashusho n'imashini ikoresha ubugeni.
