Ibisa nibitandukaniro hagati ya UV na EB Ink Gukiza

Byombi UV (ultraviolet) na EB (electron beam) ikiza ikoresha imirasire ya electromagnetic, itandukanye no gukiza ubushyuhe bwa IR (infrared). Nubwo UV (Ultra Violet) na EB (Electron Beam) bifite uburebure butandukanye bwumuraba, byombi birashobora gutuma imiti yongera kwiyongera mumashanyarazi ya wino, ni ukuvuga guhuza molekile nyinshi, bikaviramo gukira ako kanya.

Ibinyuranye, IR ikiza ikora ishyushya wino, itanga ingaruka nyinshi:

Guhumuka k'umubare muto wa solvent cyangwa ubuhehere,

● Kworoshya urwego rwa wino no kwiyongera gutemba, kwemerera kwinjiza no gukama,

Ox Okiside yo hejuru iterwa no gushyushya no guhura n'umwuka,

Imiti ivura igice cya resin hamwe namavuta menshi ya molekile munsi yubushyuhe.

Ibi bituma IR ikiza ibintu byinshi kandi byumye igice, aho kuba kimwe, cyuzuye cyo gukiza. Irangi rishingiye kumashanyarazi ryongeye gutandukana, kuko gukira kwabo kugerwaho 100% no guhumeka neza bifashwa numwuka.

Itandukaniro hagati ya UV na EB Gukiza

Gukiza UV bitandukanye na EB gukiza cyane mubwimbitse. Imirasire ya UV ifite aho igarukira; kurugero, igipimo cya wino ya 4-5 µm isaba gukira buhoro hamwe nurumuri rwinshi rwa UV. Ntishobora gukira kumuvuduko mwinshi, nkimpapuro 12,000-15,000 kumasaha mugucapisha offset. Bitabaye ibyo, ubuso bushobora gukira mugihe urwego rwimbere rugumye rutemba-nkamagi adatetse - birashobora gutuma ubuso bwongera gushonga no gukomera.

UV yinjira nayo iratandukanye cyane bitewe nibara rya wino. Inkingi ya Magenta na Cyan irinjira byoroshye, ariko wino yumuhondo numukara ikurura UV nyinshi, kandi wino yera igaragaza UV nyinshi. Kubwibyo, gahunda yo gutondekanya amabara mugucapura bigira ingaruka zikomeye kuri UV. Niba wino y'umukara cyangwa umuhondo hamwe na UV nyinshi yinjira hejuru, wino itukura cyangwa Ubururu irashobora gukira bidahagije. Ibinyuranye, gushyira wino itukura cyangwa Ubururu hejuru na Umuhondo cyangwa Umukara munsi byongera amahirwe yo gukira byuzuye. Bitabaye ibyo, buri bara rishobora gusaba gukira gutandukanye.

Ku rundi ruhande, gukiza kwa EB, nta tandukaniro rishingiye ku ibara mu gukiza kandi rifite kwinjira cyane. Irashobora kwinjira mu mpapuro, plastike, hamwe nizindi nteruro, ndetse igakiza impande zombi icapiro icyarimwe.

Ibitekerezo bidasanzwe

Irangi ryera ryera riragoye cyane gukiza UV kuko ryerekana urumuri rwa UV, ariko gukira kwa EB ntacyo bitwaye nibi. Iyi ni imwe mu nyungu za EB kurenza UV.

Nyamara, gukiza EB bisaba ko ubuso bwaba ahantu hatarimo ogisijeni kugirango habeho gukira bihagije. Bitandukanye na UV, ishobora gukiza mu kirere, EB igomba kongera ingufu zirenze icumi mu kirere kugirango igere ku bisubizo bisa - igikorwa kibi cyane gisaba kwirinda umutekano muke. Igisubizo gifatika nukuzuza icyumba gikiza na azote kugirango ukureho ogisijeni kandi ugabanye kwivanga, kwemerera gukira neza.

Mubyukuri, mu nganda ziciriritse, amashusho ya UV no kwerekana akenshi bikorwa mu byumba byuzuye azote, bitarimo ogisijeni kubera impamvu imwe.

EB gukiza rero birakwiriye gusa kumpapuro zoroshye cyangwa firime ya plastike mugutwikira no gucapa. Ntibikwiye kumashini yagaburiwe impapuro hamwe n'iminyururu ya mashini hamwe na grippers. Kuvura UV, bitandukanye, birashobora gukorerwa mu kirere kandi ni ngirakamaro, nubwo gukiza UV kutagira ogisijeni gukoreshwa gake mu gucapa cyangwa gutwikira porogaramu muri iki gihe.
