amakuru

Imashini ya Ultraviolet (UV absorber) ni stabilisateur yumucyo ishobora gukurura igice cya ultraviolet yumucyo wizuba hamwe numucyo wa fluorescent utabanje kwihindura. 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 organic 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 ningaruka zibangamira steric. 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 bishobora kuzamura urumuri na ogisijeni yibicuruzwa bya plastiki yo hanze hanze inshuro nyinshi. Kubicuruzwa bya pulasitike bifite amabara yerekana amabara kandi yifotora (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.Gushyira mu byiciro ukurikije imikoreshereze: imiti ya ultraviolet irashobora kugabanywa mu rwego rwo kwisiga, urwego rwibiryo, urwego rwa farumasi, nibindi. Imiti yo kwisiga yo mu bwoko bwa UV ikoreshwa cyane cyane mu zuba ryizuba, ibicuruzwa byita ku ruhu hamwe nandi mavuta yo kwisiga, ibyokurya byo mu rwego rwa UV bikoreshwa cyane mubikoresho bipakira ibiryo, naho imiti ya UV ikoreshwa cyane mubiyobyabwenge.
