Oligomers Yifashishijwe munganda za UV Ink

Oligomers ni molekile zigizwe na buke zisubiramo, kandi nibintu byingenzi bigize wino ishobora gukira. Inkingi ya UV ishobora gukira ni wino ishobora gukama no gukira ako kanya uhuye nurumuri ultraviolet (UV), ibyo bikaba byiza muburyo bwo gucapa byihuse no gutwikira. Oligomers igira uruhare runini muguhitamo imiterere nimikorere ya wino ishobora gukira, nka viscosity, adhesion, flexible, uramba, nibara.

Hariho ibyiciro bitatu byingenzi bya UV ikiza oligomers, aribyo epoxy acrylates, polyester acrylates, na urethane acrylates. Buri cyiciro gifite imiterere yacyo nibisabwa, bitewe n'ubwoko bwa substrate, uburyo bwo gukiza, hamwe nubwiza bwibicuruzwa byanyuma.

Epoxy acrylates ni oligomers ifite amatsinda ya epoxy mumugongo, hamwe nitsinda rya acrylate kumpera yabo. Bazwiho gukora cyane, kutagira ubukonje buke, no kurwanya imiti myiza. Ariko, bafite kandi ibibi bimwe na bimwe, nko guhinduka nabi, gufatira hamwe, no guhinduka umuhondo. Epoxy acrylates irakwiriye gucapishwa kumasoko akomeye, nk'icyuma, ikirahure, na plastiki, hamwe na porogaramu zisaba ububengerane bukomeye.

Polyester acrylates ni oligomers ifite amatsinda ya polyester mumugongo, hamwe nitsinda rya acrylate kumpera yabo. Bazwiho gukora neza, kugabanuka gake, no guhinduka neza. Nyamara, bafite kandi ibibi bimwe na bimwe, nk'ubukonje bwinshi, imiti irwanya imiti, hamwe n’ibyuka bihumanya. Polyester acrylates irakwiriye gucapishwa kubintu byoroshye, nkimpapuro, firime, nigitambara, hamwe nibisabwa bisaba gufatana neza no gukomera.

Urethane acrylates ni oligomers ifite urethane mumatsinda yumugongo, hamwe nitsinda rya acrylate kumpera yabo. Bazwiho kutitwara neza, kwiyegeranya kwinshi, no guhinduka neza. Nyamara, bafite kandi ibibi bimwe, nkigiciro cyinshi, kubuza ogisijeni mwinshi, n'umuvuduko muke wo gukira. Urethane acrylates irakwiriye gucapishwa kubintu bitandukanye, nkibiti, uruhu, na reberi, hamwe nibisabwa bisaba kuramba cyane no kurwanya abrasion.

Mu gusoza, oligomers ningirakamaro mugutegura no gukora wino ya UV ishobora gukira, kandi irashobora gushyirwa mubyiciro bitatu byingenzi, aribyo epoxy acrylates, polyester acrylates, na urethane acrylates. Buri cyiciro gifite ibyiza byacyo nibibi, bitewe na progaramu na substrate. Iterambere rya oligomers na wino ya UV ninzira ikomeza, kandi ubwoko bushya bwa oligomeri nuburyo bwo gukiza burimo gushakishwa kugirango ibyifuzo byinganda ziyongera.
