Mbere na mbere byombi Amazi (ashingiye kumazi) hamwe na UV yatwikiriye gukoreshwa cyane mubikorwa bya Graphics Arts Industry nkamakoti yo hejuru arushanwa. Byombi bitanga ubwiza bwiza no kurinda, byongerera agaciro ibicuruzwa bitandukanye byacapwe.
Itandukaniro muburyo bwo gukiza
Icyibanze, uburyo bwo kumisha cyangwa gukiza byombi biratandukanye. Amazi yo mumazi yumye mugihe ibice bitwikiriye bihindagurika (hafi 60% byamazi) bihatirwa guhumeka cyangwa igice cyinjizwa mubutaka bworoshye. Ibi bituma ibishishwa bya solide bihurira hamwe kugirango bibe byoroshye, byumye gukoraho, firime.
Itandukaniro ni UV itwikiriye ikozwe hifashishijwe ibice 100% byamazi (nta volatile) ikiza cyangwa ifotora mumashanyarazi make ya Photochemical cross-ihuza reaction iyo ihuye numucyo mugufi wa ultraviolet (UV). Uburyo bwo gukiza butera impinduka zihuse, zihindura amazi mumazi ahita (guhuza) gukora firime yumye.
Itandukaniro mubikoresho byo gusaba
Kubijyanye nibikoresho bikoreshwa, byombi bitagaragara neza byamazi & UV bitwikiriye birashobora gukoreshwa neza ukoresheje inkeri yanyuma muri flexo & gravure yamazi yo gucapa. Ibinyuranyo, urubuga nurupapuro rwagaburiwe offset litho paste wino yo gucapa bisaba ko kongeramo ikariso-kongeramo kugirango ushyireho amazi yo mu mazi cyangwa UV. Inzira ya ecran nayo ikoreshwa mugukoresha UV.
Imashini icapura ya Flexo na gravure ifite ubushobozi bukenewe bwo gukanika & wino wamazi yo mumazi yamaze gushyirwaho kugirango yumishe neza amazi. Urubuga rwa offset ubushyuhe bwashyizweho bwo gucapa nabyo byagaragaye ko bifite ubushobozi bukenewe bwo gukama kuma kuma. Ariko, nikindi kibazo mugihe usuzumye urupapuro rwagaburiwe offset yo gucapa. Hano gukoresha ibishishwa byamazi bisaba ko hashyirwaho ibikoresho byihariye byo kumisha bigizwe n’ibisohoka byangiza, ibyuma bishyushye byo mu kirere, hamwe n’ibikoresho byo gukuramo umwuka.
Itandukaniro mugihe cyumye
Gutanga kwagutse birasabwa kandi gutanga igihe cyumye. Iyo usuzumye gukama (gukiza) gutwika UV cyangwa wino, itandukaniro riri muburyo bwibikoresho byihariye byo gukama (gukiza) bisabwa. Sisitemu yo gukiza UV itanga cyane cyane urumuri rwa UV rutangwa nigitutu cyo hagati ya mercure arc amatara, cyangwa amasoko ya LED afite ubushobozi buhagije bwo gukiza neza kumuvuduko ukenewe.
Amazi yo mumazi arimo gukama vuba kandi hagomba kwitonderwa gusukura mugihe cyose abanyamakuru bahagaritse. Itandukaniro ni UV coatings guma ufunguye kanda mugihe cyose nta mucyo UV uhari. Inkingi ya UV, ibifuniko, hamwe na langi ntabwo byumye cyangwa gucomeka selile ya anilox. Ntibikenewe koza hagati yikinyamakuru cyangwa muri wikendi, kugabanya igihe cyimyanda.
Byombi byamazi & UV birashobora gutanga umucyo mwinshi, hamwe nurwego rwo kurangiza kuva hejuru cyane, binyuze muri satine kugeza matte. Itandukaniro ni UV itwikiriye irashobora gutanga gloss yo hejuru cyane hamwe nuburebure butagaragara.
Itandukaniro muri Coatings
Amazi yo mumazi muri rusange atanga rubavu nziza, mar, hamwe no gukumira. Ibicuruzwa byateguwe byamazi byamazi birashobora kandi gutanga amavuta, inzoga, alkali, hamwe nubushyuhe. Itandukaniro ni impuzu za UV mubisanzwe, genda indi ntambwe itanga neza cyane abrasion, mar, guhagarika, imiti, hamwe no kurwanya ibicuruzwa.
Amazi ya Thermoplastique yo mumazi yo kugaburira urupapuro rwa offset ya litiro yatunganijwe kugirango agwe kumurongo umutego utose hejuru ya wino yumye yumye, kugabanya cyangwa gukuraho ibikenerwa byifu ya spray ikoreshwa kugirango wirinde kwangirika. Ubushyuhe bwikirundo bugomba kubungabungwa murwego rwa 85-95®F kugirango wirinde koroshya igishishwa cyumye ku bushyuhe bwinshi, hamwe nubushobozi bwo guhagarika no guhagarika. Ibyiza, umusaruro uratera imbere nkuko impapuro zitwikiriye zishobora gutunganywa vuba.
Itandukaniro ni UV itwikiriye ikoreshwa kumurongo utose hejuru ya wino ya UV byombi bikira kuri press-end, kandi impapuro zirashobora gutunganywa ako kanya. Iyo UV itwikiriye wino isanzwe ya litho isanzwe ifatwa nkibibanza byamazi birasabwa gufunga no gukomera kuri wino kugirango bitange umusingi wa UV. Hybrid UV / wino isanzwe irashobora gukoreshwa muguhakana icyifuzo cya primer.
Ingaruka ku bantu, ibiryo, n'ibidukikije
Amazi yo mu mazi atanga umwuka mwiza, VOC nkeya, inzoga zeru, umunuko muke, kudakongoka, kutagira uburozi, nibintu bidahumanya. Mu buryo nk'ubwo, 100% ibishishwa bya UV bitanga ibyuka bihumanya, zero VOC, kandi ntibishobora gutwikwa. Itandukaniro ni wet itavanze neza ya UV irimo ibintu bishobora kuba bifite impumuro ikaze, kandi birashobora kuva kuri bike kugeza bikabije nkibitera, bishobora gutera allergie reaction kubantu bamwe. Uruhu n'amaso bigomba kwirindwa. Icyitonderwa cyiza, imiti ivura UV yagenwe nka "Ikoreshwa ryiza rya tekinoroji iboneka" (BACT) na EPA, igabanya imyuka ya VOC, imyuka ya CO2, hamwe ningufu zisabwa.
Amazi yo mu mazi arashobora guhinduka mugihe cyo gutangaza amakuru kubera guhinduka kwimyuka ihindagurika, hamwe na Ph. Itandukaniro ni 100% ikomeye ya UV itwikiriye ikomeza guhora mukanda mugihe cyose nta mucyo UV uhari.
Amazi yumye yumye arashobora gukoreshwa, kubora kandi birashobora kwangwa. Itandukaniro nigihe mugihe UV yakize ikozwe neza kandi irashobora kwangwa, itinda kuri biodegrade. Ibi ni ukubera gukiza ibice byambukiranya ibice,
kubyara ibintu byombi birwanya umubiri na chimique.
Amazi yo mumazi yumye hamwe nubusobanuro bwamazi adafite umuhondo ujyanye nimyaka. Itandukaniro nuko UV yakize ishobora kandi kwerekana umucyo mwinshi, ariko hagomba kwitonderwa mugutegura kuko ibikoresho bimwe bibisi bishobora kubyara umuhondo.
Amazi yo mumazi arashobora guhuza namabwiriza ya FDA kubiribwa byumye kandi / cyangwa bitose byamavuta. Itandukaniro nuko UV itwikiriye, usibye uburyo bwihariye bwihariye, ntibushobora kubahiriza amabwiriza ya FDA kubijyanye no guhunika ibiryo byumye cyangwa bitose / amavuta.
Inyungu
Usibye gutandukana, amazi & UV yatwikiriye asangira inyungu nyinshi kurwego rutandukanye. Kurugero, formulaire yihariye irashobora gutanga ubushyuhe, amavuta, inzoga, alkali, hamwe nubushyuhe. Ikigeretse kuri ibyo, barashobora gutanga gluability cyangwa glue resistance, urutonde rwa COF, ubushobozi bwo gucapa, kwemerwa na fayili ishyushye cyangwa imbeho, ubushobozi bwo kurinda wino yumutare, kongera umusaruro, gutunganya umurongo, ubushobozi bwakazi, no kuzigama, kuzigama ingufu, nta gushiraho, no kurupapuro rwuzuye rwo gukuraho ifu ya spray.
Ubucuruzi bwacu muri Cork Industries niterambere no gushiraho Amazi meza, akiza ingufu Ultraviolet (UV), hamwe na Electron Beam (EB) impuzu zidasanzwe hamwe na adhesives. Cork itera imbere mubushobozi bwayo bwo gukora udushya, ingirakamaro zidasanzwe zitanga ibishushanyo mbonera byinganda zicapa / coater inyungu zo guhatanira.
