Ikoranabuhanga rya foil ikonje
Ikoranabuhanga ryo gusiga irangi mu buryo bukonje risobanura uburyo bwo kohereza irangi rishyushye mu bikoresho byo gucapa hakoreshejwe kole ya UV. Uburyo bwo gusiga irangi mu buryo bukonje bushobora kugabanywamo irangi ryumutse rigashyirwa mu buryo bukonje n'irangi ryumutse rigashyirwa mu buryo bukonje.
1. Intambwe zo gukora
Uburyo bwo gusiga irangi ry'umunyu mu gihe cyo gukandagira mu buryo bukonje
Kole ya UV ipfutse ibanza kuvurwa mbere yo gusimbuza ishyushye. Ubwo ikoranabuhanga ryo gusimbuza imashini ikora ku buryo bukonje ryatangiraga, hakoreshejwe uburyo bwo gusimbuza imashini ikora ku buryo bukonje, kandi intambwe nyamukuru z'ibikorwa byayo ni izi zikurikira:
1) Capa kole ya cationic UV ku gikoresho cyo gucapa umuzingo.
2) Kuraho kole ya UV.
3) Koresha agakoresho gapima umuvuduko kugira ngo wongereho agapapuro gakonje gapima n'ibikoresho byo gucapa.
4) Kuramo agapapuro gashyushye gahagije gashyirwa ku bikoresho byo gucapa, usige gusa ishusho n'inyandiko bikenewe byo gushyiramo agapapuro gashyushye ku gice gitwikiriwe n'ubudodo.
Ni ngombwa kumenya ko iyo ukoresheje uburyo bwo gusiga irangi ry’umurabyo mu buryo bw’umukara, kole ya UV igomba kuvurwa vuba, ariko ntabwo ivurwa burundu. Ni ngombwa kumenya neza ko igifite ubukana runaka nyuma yo kuvurwa kugira ngo ibashe guhuzwa neza n’urupapuro rushyushye rwo gusiga irangi.
Uburyo bwo gusiga irangi rikonje mu mazi
Nyuma yo gukoresha kole ya UV, habanza gukorwa imashini ishyushye hanyuma kole ya UV igakira. Intambwe z'ingenzi ni izi zikurikira:
1) Gucapa kole ya UV ikoresheje radical free radical ku gice cyo hasi cy'umuzingo.
2) Guteranya ifuro rikonje ku gice cy'ubutaka.
3) Gutunganya kole ya UV ikoresheje radical yigenga. Kubera ko kole iba iri hagati y’ibumba rikonje n’ibumba muri iki gihe, urumuri rwa UV rugomba kunyura muri kole ishyushye kugira ngo rugere ku gice cy’ibumba.
4) Gukuramo agapapuro gashyushye gashyirwa ku gice cy'ubutaka hanyuma ugashyiraho ishusho ishyushye yo gushyira ku gice cy'ubutaka.
Icyitonderwa ni uko:
Uburyo bwo gusiga irangi ry’amazi mu buryo bukonje bukoresha kole ya UV ikoresha radical free radical kugira ngo isimbuze kole isanzwe ya cationic UV;
Uburyo bwa mbere bwo gufatana kwa kole ya UV bugomba kuba bukomeye, kandi ntibugomba gukomeza gufatana nyuma yo gushonga;
Urupapuro rwa aluminiyumu rw'icyuma gishyushye cyo gusigaho irangi rugomba kugira uburyo runaka bwo kohereza urumuri kugira ngo urumuri rwa UV rushobore kunyuramo no gutera ingaruka zo gucika kw'urumuri rwa UV.
Uburyo bwo gukata imashini mu buryo bukonje bushobora gukata imashini mu buryo bushyushye cyangwa imashini ya holographic ku mashini icapa, kandi urwego rw'ikoreshwa ryayo ruriyongera. Muri iki gihe, imashini nyinshi zo gucapa zifite ubugari buto n'ibirango bya flexographic zifite ubu bushobozi bwo gukata imashini mu buryo bukonje kuri interineti.
