Oligomer zikoreshwa mu nganda za wino ya UV

Oligomer ni molekile zigizwe n'ibice bike bisubiramo, kandi ni byo bice by'ingenzi bya wino zishobora kuvurwa na UV. Wino zishobora kuvurwa na UV ni wino zishobora kumanywa no kuvurwa ako kanya bitewe n'urumuri rwa ultraviolet (UV), ibyo bigatuma ziba nziza cyane mu gucapa no gusiga irangi ryihuse. Oligomer zigira uruhare runini mu kugena imiterere n'imikorere ya wino zishobora kuvurwa na UV, nko kuba ubushyuhe, gufatana, koroherana, kuramba, n'ibara.

Hari ubwoko butatu bw'ingenzi bwa oligomer zishobora kuvurwa n'imirasire y'urumuri, ari zo epoxy acrylates, polyester acrylates, na urethane acrylates. Buri bwoko bufite imiterere n'imikorere yabwo, bitewe n'ubwoko bw'ubutaka, uburyo bwo gukaraba, n'ubwiza bw'umusaruro wa nyuma wifuza.

Epoxy acrylate ni oligomer zifite amatsinda ya epoxy mu mugongo wazo, n'amatsinda ya acrylate ku mpera zazo. Zizwiho gukora cyane, viscosity nke, no kudakoresha imiti neza. Ariko, zifite n'imbogamizi zimwe na zimwe, nko kudakomera neza, gufatana guke, no guhinduka umuhondo. Epoxy acrylate zikwiriye gucapwa ku bintu bikomeye, nk'icyuma, ikirahure, na pulasitiki, ndetse no gukoreshwa mu buryo busaba ubukana n'ubukomere bwinshi.

Akrilati za polyester ni oligomer zifite amatsinda ya polyester mu mugongo wazo, n'amatsinda ya akrilati ku mpera zazo. Zizwiho gukora neza mu buryo buri hagati, kugabanuka guke, no koroha gukomeye. Ariko, zifite n'imbogamizi zimwe na zimwe, nko kuba zifite ubukana bwinshi, kudakoresha imiti myinshi, no gusohora impumuro mbi. Akrilati za polyester zikwiriye gucapwa ku bintu byoroshye, nk'impapuro, filimi, n'imyenda, ndetse no gukoreshwa mu buryo busaba gufatana neza no guhindagurika.

Akrilati za Urethane ni oligomer zifite amatsinda ya urethane mu mugongo wazo, n'amatsinda ya akrilati ku mpera zazo. Zizwiho gukora nabi, ubushyuhe bwinshi, no koroha cyane. Ariko, zifite n'imbogamizi zimwe na zimwe, nko guhenda cyane, kudakoresha umwuka mwinshi wa ogisijeni, no kwihuta guke mu kuvura. Akrilati za Urethane zikwiriye gucapwa ku bintu bitandukanye, nk'ibiti, uruhu, na kawunga, ndetse no gukoreshwa mu buryo busaba kuramba cyane no kudashwanyagurika.

Muri make, oligomer ni ingenzi mu gukora no gukora inyito za UV zishobora kuvurwa, kandi zishobora gushyirwa mu byiciro bitatu by'ingenzi, ari byo epoxy acrylates, polyester acrylates, na urethane acrylates. Buri cyiciro gifite ibyiza n'ibibi byacyo, bitewe n'ikoreshwa n'aho giherereye. Iterambere rya oligomer na UV wino ni igikorwa gikomeje, kandi ubwoko bushya bwa oligomer n'uburyo bwo gusiga irangi burimo gusuzumwa kugira ngo hahuzwe n'ibyifuzo byiyongera by'inganda za wino.
