amakuru

Ultraviolet absorber (UV absorber) ni stabilisateur yumucyo ishobora gukurura igice cya ultraviolet yumucyo wizuba hamwe nurumuri rwa fluorescent idahinduye ubwayo. Imashini ya Ultraviolet ni ifu ya kirisiti yera, ituje neza yumuriro, imiti ihamye, itagira ibara, idafite uburozi, impumuro nziza, ikoreshwa muri polymers (plastike, nibindi), gutwikira nibindi.

Amabara menshi, cyane cyane amabara ya pigment ya organique, arashobora gukina urwego runaka rwumucyo iyo rukoreshejwe wenyine mubicuruzwa bya plastiki. Kubicuruzwa bya pulasitiki byamabara yo gukoresha hanze igihe kirekire, urumuri rwumucyo rwibicuruzwa ntirushobora kunozwa nibara ryonyine. Gusa gukoresha stabilisateur yumucyo birashobora kubuza neza cyangwa kugabanya umuvuduko wo gusaza wumucyo wibicuruzwa bya plastiki byamabara igihe kirekire. Gutezimbere kuburyo bugaragara urumuri rwibicuruzwa bya plastiki. Inzitizi ya amine yumucyo (HALS) nicyiciro cyimvange ya amine kama ningaruka mbi. Bitewe ninshingano zayo zo kubora hydroperoxide, kuzimya ogisijeni ya radical, gufata imitego yubusa, no gutunganya amatsinda meza, HALS ni stabilisitiya yumucyo wa plastike ifite imbaraga zo kurwanya amafoto menshi kandi menshi murugo ndetse no mumahanga. Amakuru yerekana ko stabilisateur yumucyo ikwiye cyangwa sisitemu ikwiye yo guhuza antioxydeant na stabilisateur yumucyo irashobora kuzamura urumuri na ogisijeni yibicuruzwa bya plastiki byo hanze hanze inshuro nyinshi. Kubicuruzwa bya pulasitike bifite amabara yerekana amabara kandi yerekana amafoto (nkumuhondo wa kadmium, rutile idafite ibara, nibindi), urebye ingaruka zifotora ya catalitiki yibara ryamabara, ingano ya stabilisateur yumucyo igomba kwiyongera uko bikwiye.

Imashini ya Uv irashobora gushyirwa mubice ukurikije imiterere yimiti, igice cyibikorwa no gukoresha, byasobanuwe hepfo:

1.Gushyira mu byiciro ukurikije imiterere yimiti: imashini ya ultraviolet irashobora kugabanywamo ibinyabuzima bya ultraviolet hamwe na ultraviolet. Imashini ya ultraviolet ikurura cyane cyane irimo benzoates, benzotriazole, cyanoacrylate, nibindi, mugihe imashini itwara ultraviolet ikuramo cyane cyane harimo zinc oxyde, okiside yicyuma, dioxyde ya titanium nibindi.

2.Gushyira muburyo ukurikije uburyo bwibikorwa: imashini ya ultraviolet irashobora kugabanywa muburyo bwo gukingira nubwoko bwinjira. Gukingira imashini ya UV irashobora kwerekana urumuri rwa UV bityo ikayirinda kwinjira mu mubiri, mugihe iyinjizamo UV irashobora kwinjiza urumuri rwa UV ikayihindura ubushyuhe cyangwa urumuri rugaragara.

3.Icyiciro ukurikije imikoreshereze: imashini ya ultraviolet irashobora kugabanywa mubyiciro byo kwisiga, urwego rwibiryo, urwego rwa farumasi, nibindi. ibikoresho byo gupakira, hamwe na farumasi yo mu rwego rwa UV ikoreshwa cyane mubiyobyabwenge.
