Mu myaka ya vuba aha, twibanda ku bisubizo birambye, tubona ko hari kwiyongera gukenewe ibikoresho birambye n’ibishingiye ku mazi, aho gukoresha ibikoresho bishingiye ku binyabutabire. Gukoresha imirasire ya UV ni ikoranabuhanga rikoresha ikoranabuhanga rikoresha ikoranabuhanga rigezweho mu myaka yashize. Mu guhuza ibyiza byo gukoresha imirasire ya UV vuba kandi ifite ireme n’ikoranabuhanga rikoreshwa mu gukoresha amazi, birashoboka kubona ibyiza bibiri birambye.
Kongera imbaraga mu ikoranabuhanga mu iterambere rirambye
Iterambere ridasanzwe ry’icyorezo mu 2020, ryahinduye cyane uburyo tubaho n’imikorere yacu y’ubucuruzi, ryagize ingaruka ku kwibanda ku gutanga serivisi zirambye mu nganda zikora imiti. Imihigo mishya irashyirwaho ku nzego za politiki zikomeye ku migabane myinshi, ubucuruzi buhatirwa gusuzuma ingamba zabwo kandi imihigo irambye irasuzumwa kugeza ku tuntu duto. Kandi ni mu bisobanuro birambuye ibisubizo bishobora kuboneka ku buryo ikoranabuhanga rishobora gufasha abantu n’ibigo mu buryo burambye. Uburyo ikoranabuhanga rishobora gukoreshwa no guhuzwa mu buryo bushya, urugero nko guhuza ikoranabuhanga rya UV na sisitemu zishingiye ku mazi.
Iterambere ry'ikoranabuhanga ryo gusiga UV mu bidukikije
Ikoranabuhanga ryo gupima imirasire y'izuba ryatangiye gukorwa mu myaka ya za 1960 hakoreshejwe imiti idahagije kugira ngo ivurwe hakoreshejwe urumuri rwa UV cyangwa Electron Beams (EB). Ihuriro ryitwaga radiation curing, inyungu nini yari ugupima imirasire y'izuba ako kanya no kuba ifite ubushobozi bwiza bwo gusiga. Mu myaka ya za 80, ikoranabuhanga ryateye imbere ritangira gukoreshwa mu bucuruzi. Uko abantu bagendaga bamenya ingaruka z'imirasire ku bidukikije, ni ko gupima imirasire y'izuba byarushijeho gukundwa nk'uburyo bwo kugabanya ingano y'imirasire ikoreshwa. Iyi nzira ntiyigeze igabanuka kandi kuva icyo gihe hakomeje kwiyongera ikoreshwa n'ubwoko bw'imikoreshereze, ndetse n'ubusabe bwakomeje kugaragara haba mu mikorere no mu buryo burambye.
Kureka gukoresha imiti isukura
Nubwo gupima UV ubwabyo ari ikoranabuhanga rirambye cyane, hari uburyo bumwe na bumwe buracyasaba gukoresha ibintu bisukura cyangwa monomer (bifite ibyago byo kwimuka) kugira ngo bigabanye ubukana bw'amazi kugira ngo haboneke umusaruro ushimishije mu gihe cyo gushyiramo irangi cyangwa wino. Vuba aha, havutse igitekerezo cyo guhuza ikoranabuhanga rya UV n'irindi koranabuhanga rirambye: sisitemu zishingiye ku mazi. Izi sisitemu muri rusange ziba iz'ubwoko bushongesha amazi (byaba binyuze mu gutandukanya ionic cyangwa guhuza amazi) cyangwa iz'ubwoko bwa PUD (polyurethane dispersion) aho ibitonyanga by'igice kidashongesha amazi bikwirakwira mu mazi binyuze mu gukoresha igikoresho gikwirakwiza amazi.
Uretse gusiga irangi ku mbaho
Mbere na mbere, irangi rya UV rituruka mu mazi ryakoreshejwe cyane cyane n’inganda zikora irangi ry’ibiti. Aha byari byoroshye kubona ibyiza byo guhuza inyungu zituruka ku musaruro mwinshi (ugereranije n’izitari UV) n’ubudahangarwa bwinshi bw’ibinyabutabire hamwe na VOC nkeya. Imiterere y’ingenzi mu irangi rya UV ryo hasi no mu bikoresho. Ariko, vuba aha hari izindi porogaramu zatangiye kuvumbura ubushobozi bwa UV ishingiye ku mazi. Icapiro rya digitale rya UV rishingiye ku mazi (inkjet inks) rishobora kungukira ku byiza bya UV ishingiye ku mazi (ubudahangarwa buke na VOC nkeya) ndetse na UV incaring (incaring yihuta, ubushobozi bwiza no kudahangarwa n’ibinyabutabire). Iterambere ririmo gutera imbere vuba kandi birashoboka ko izindi porogaramu nyinshi zizasuzuma vuba amahirwe yo gukoresha UV ishingiye ku mazi.
Urangi rw'imirasire y'imirasire y'izuba ishingiye ku mazi hose?
Twese tuzi ko isi yacu ihanganye n'ibibazo bimwe na bimwe biri imbere. Kubera ko abaturage biyongera kandi imibereho y'abaturage igakomeza kwiyongera, ikoreshwa ry'ibintu bityo n'imicungire y'umutungo irushaho kuba ingenzi kurusha mbere hose. Gukoresha imirasire ya UV ntabwo bizaba igisubizo cy'ibi bibazo byose ariko bishobora kuba kimwe mu bintu bishya nk'ikoranabuhanga rikoresha ingufu n'umutungo. Ikoranabuhanga gakondo rikoresha imirasire ya UV risaba uburyo bwo kumisha ingufu nyinshi, hamwe no gusohora VOC. Gukoresha imirasire ya UV bishobora gukorwa hakoreshejwe amatara ya LED afite ingufu nke ku byuma bidafite imirasire cyangwa, nk'uko twabyize muri iyi nkuru, hakoreshejwe amazi gusa nk'imirasire. Guhitamo ikoranabuhanga rirambye n'ubundi buryo bushoboka bigufasha kurinda hasi mu gikoni cyawe cyangwa mu bubiko bw'ibitabo ukoresheje igitambaro cyiza cyane, ahubwo no kurinda no kumenya umutungo muke w'isi yacu.
