imiterere y'ibinyabutabire

Umuyoboro w’imirasire ya ultraviolet ni ubwoko bw’umuyoboro utuma urumuri rudahinduka, ushobora kwinjiza urumuri rw’izuba n’urumuri rw’imirasire ya fluorescent mu gice cy’imirasire ya ultraviolet, ariko ubwawo ntuhinduka.
Kubera ko imirasire y'izuba irimo urumuri rwinshi rwa ultraviolet rwangiza ibintu bifite amabara, uburebure bwarwo bungana na nanometero 290-460, urwo rumuri rwa ultraviolet rwangiza binyuze muri Redox reaction y'ibinyabutabire, molekile z'amabara zirabora hanyuma zigashira.
Hari uburyo bwo kwirinda kwangirika kw'amabara bitewe n'urumuri rwangiza imirasire y'izuba, haba mu buryo bufatika ndetse no mu buryo bwa shimi.
Dore incamake y'uburyo bwa chimique, ni ukuvuga ikoreshwa ry'ibikoresho bigabanya ubushyuhe bwa UV mu kurinda ikintu neza, cyangwa kugabanya kwangirika kwacyo kw'amabara.
Ibikoresho bigabanya imirasire y'izuba bigomba kuba bifite ibi bikurikira
(1) ishobora gukurura cyane urumuri rwa ultraviolet (cyane cyane uburebure bwa 290-400nm); (2) Ubushyuhe buhamye, nubwo butunganywa ntibuhinduka bitewe n'ubushyuhe, ubushyuhe burahindagurika buhoro; Ubushyuhe buhamye, nta ngaruka mbi ku bice bigize ibikoresho biri mu gicuruzwa; (4) Gutandukana neza, bishobora gukwirakwizwa mu bikoresho ku buryo bungana, nta bukonje, nta gusohoka; (5) Ubushyuhe buhamye bw'icyuma gifata amazi ubwacyo ni bwiza, ntibubora, ntibuhindura ibara; ⑥ Nta ibara, ntabwo ari uburozi, nta mpumuro; ⑦ Irwanya gukaraba mu mazi; ⑧ Ihendutse kandi yoroshye kubona; 9. Ntishobora gushonga cyangwa gushonga mu mazi.
Ibikoresho bigabanya imirasire y'izuba bishobora gushyirwa mu matsinda akurikira hakurikijwe imiterere yabyo: salicylate esters, phenylketones, benzotriazoles, substituted acrylonitrile, triazines na blocked amines.

Intangiriro y'ibicuruzwa n'ibiranga

Umuyoboro w’imirasire ya ultraviolet ni wo ukoreshwa cyane mu gupima urumuri, ukurikije imiterere yawo ushobora kugabanywamo salicylate esters, benzophenone, benzotriazole, acrylonitrile yasimbuwe, triazines, nibindi, ikoreshwa mu nganda rya benzophenone na benzotriazole cyane. Umuyoboro w’imirasire ya ultraviolet ahanini ni complex y’icyuma, nka divalent nickel complex, akenshi na ultraviolet ifata kandi, ingaruka za synergistic, umuyoboro w’imirasire ya ultraviolet ni ubwoko bwa stabilizer y’urumuri, ishobora gufata urumuri rw’izuba n’urumuri rwa fluorescent mu gice cya ultraviolet, kandi ubwayo ntabwo ihinduka.
Kubera ko imirasire y'izuba irimo urumuri rwinshi rwa ultraviolet rwangiza ibintu bifite amabara, uburebure bwarwo bungana na nanometero 290-460, urwo rumuri rwa ultraviolet rwangiza binyuze muri Redox reaction y'ibinyabutabire, molekile z'amabara zirabora hanyuma zigashira.
Hari uburyo bwo kwirinda kwangirika kw'amabara bitewe n'urumuri rwangiza imirasire y'izuba, haba mu buryo bufatika ndetse no mu buryo bwa shimi.
Dore incamake y'uburyo bwa shimi, ni ukuvuga ikoreshwa ry'ibikoresho bigabanya ubushyuhe bwa UV mu kurinda ikintu neza, cyangwa kugabanya kwangirika kwacyo kw'amabara.

gukoresha

Ishobora kwakira urumuri rwa ultraviolet neza ifite uburebure bwa 270-380 nm, ikoreshwa cyane cyane muri polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymethyl methacrylate, polyethylene, ABS resin, epoxy resin na cellulose resin, nibindi. Ikwiriye ibikoresho byoroshye gufotora nka filimi y'amabara, filimi y'amabara, impapuro z'amabara na polymer, nibindi. Ikwiriye cyane cyane ibicuruzwa bitagira ibara kandi byoroheje; Ifasha mu gufata neza, ikoresha ultraviolet absorbers cyane.

gupakira no gutwara

B. Iki gicuruzwa gishobora gukoreshwa, 25KG, BAERRLS.
C. Bika ahantu hakonje, humutse kandi hafite umwuka mwiza mu nzu. Ibikoresho bigomba gufungwa neza nyuma ya buri gihe mbere yo kubikoresha.
D. Iki gicuruzwa kigomba gufungwa neza mu gihe cyo kugitwara kugira ngo hirindwe ubushuhe, alkali na aside nyinshi, imvura n'indi myanda kuvanga.
