amakuru

Umuyoboro wa Ultraviolet (UV absorber) ni umuyoboro w’urumuri ushobora gukurura igice cy’izuba n’urumuri rwa fluorescent utihinduye. Umuyoboro wa Ultraviolet ahanini ni ifu y’umweru, ihorana ubushyuhe, ihorana ubushyuhe, ihorana uburozi, ihorana impumuro nziza, ikoreshwa muri polymer (plastiki, nibindi), irangi n'ibindi.

Inyinshi mu mvange z’amabara, cyane cyane imvange z’amabara zidakora, zishobora kugira uruhare mu gutuma urumuri rudahinduka iyo zikoreshejwe zonyine mu bikoresho bya pulasitiki. Ku bikoresho bya pulasitiki bifite amabara yo gukoreshwa igihe kirekire hanze, ntabwo imvange y’urumuri ishobora kunozwa n’imvange y’amabara yonyine. Gukoresha imvange y’urumuri gusa bishobora kugabanya cyangwa kugabanya umuvuduko wo gusaza kw’urumuri rw’ibikoresho bya pulasitiki bifite amabara igihe kirekire. Binoza cyane uburyo urumuri rudahinduka rw’ibikoresho bya pulasitiki bifite amabara. Imvange y’amabara ya amine ibuza guhindagurika (HALS) ni ubwoko bw’ibinyabutabire bya amine bifite ingaruka mbi ku miterere ya steric. Bitewe n’imirimo yayo yo kubora hydroperoxide, kuzimya ogisijeni ikabije, gufata radicals yigenga, no kongera gukoresha amatsinda akomeye, HALS niyo ihuza urumuri rwa pulasitiki ifite ubushobozi bwo kurwanya fotografiya kandi ikaba ari nyinshi cyane mu gihugu no mu mahanga. Amakuru agaragaza ko imvange ikwiye cyangwa uburyo bukwiye bwo guhuza antioxidant n’imvange y’urumuri bishobora kunoza uburyo urumuri n’umwuka bihoraho bw’ibikoresho bya pulasitiki bifite amabara yo hanze inshuro nyinshi. Ku bicuruzwa bya pulasitiki bivangwa n'amabara akoresha ibara ry'ubushyuhe n'iry'ubushyuhe (nk'umuhondo wa cadmium, rutile idakozwe mu matara, nibindi), ukurikije ingaruka za catalytic photoaging z'amabara, ingano y'urumuri rudahinduka igomba kongerwa hakurikijwe ibyo.

Ibikoresho bigabanya imirasire y'izuba muri rusange bishobora gushyirwa mu byiciro hakurikijwe imiterere ya chimique, igice cy'ibikorwa n'imikoreshereze, ibi bikurikira:

1.Gushyira mu byiciro hakurikijwe imiterere y'imiti: imiyoboro y'urumuri rwa ultraviolet ishobora kugabanywamo imiyoboro y'urumuri rwa ultraviolet n'imiyoboro y'urumuri rwa ultraviolet. Imiyoboro y'urumuri rwa ultraviolet ya organic igizwe ahanini na benzoate, benzotriazole, cyanoacrylate, n'ibindi, mu gihe imiyoboro y'urumuri rwa ultraviolet ya ultraviolet ya ultraviolet igizwe ahanini na zinc oxyde, fer oxyde, titanium dioxide n'ibindi.

2.Gushyira mu byiciro hakurikijwe uburyo bikorwamo: icyuma gifata urumuri rw'imirasire ya ultraviolet gishobora kugabanywamo ubwoko bwo gukingira n'ubwoko bwo gufatira. Ikigo gifata urumuri rw'imirasire ya ultraviolet gishobora kugaragaza urumuri rwa UV bityo kikabuza kwinjira mu mubiri, mu gihe icyuma gifata urumuri rw'imirasire ya ultraviolet gishobora kwinjiza urumuri rwa UV kikaruhindura ubushyuhe cyangwa urumuri rugaragara.

3. Gushyira mu byiciro hakurikijwe ikoreshwa: icyuma gifata imirasire ya ultraviolet gishobora kugabanywamo urwego rw'ubwiza, urwego rw'ibiribwa, urwego rw'imiti, nibindi. Ikigonderabuzima gifata imirasire ya ultraviolet gikoreshwa cyane cyane mu kwisiga izuba, ibikoresho byo kwita ku ruhu n'ibindi bikoresho byo kwisiga, ikigonderabuzima gifata imirasire ya ultraviolet gikoreshwa cyane cyane mu bikoresho byo gupfunyika ibiryo, naho ikigonderabuzima gifata imirasire ya ultraviolet gikoreshwa cyane cyane mu miti.
