imiterere y'ibinyabutabire

Dukurikije imiterere yabyo ya shimi, bishobora kugabanywamo ibyiciro bitanu:
1, ubwoko bwa stilbene: ikoreshwa mu gutunganya ipamba n'imyenda imwe n'imwe ikoze mu budodo, mu gukora impapuro, mu isabune n'izindi nganda, hamwe n'ubururu butanga urumuri;
2, ubwoko bwa coumarin: ifite imiterere y'ibanze ya coumarin, ikoreshwa muri celluloid, pulasitiki ya PVC, ifite urumuri rw'ubururu rukomeye;
3, ubwoko bwa pyrazoline: ikoreshwa mu bwoya, polyamide, fibre acrylic n'izindi fibre, ifite ibara ry'icyatsi kibisi fluorescent;
4, ubwoko bwa azote ya benzoxy: ikoreshwa mu migozi ya acrylic na polyvinyl chloride, polystyrene n'izindi plastiki, ifite fluorescence itukura;
5, ubwoko bwa benzoimide bukoreshwa muri polyester, acrylic, nylon n'izindi fibre, hamwe n'ubururu butanga urumuri.

Intangiriro y'ibicuruzwa n'ibiranga

Ibara ry'urumuri ry'urumuri (fluorescent brightener) ni irangi ry'urumuri, cyangwa irangi ry'umweru, ari naryo rikoreshwa mu gukurura itsinda ry'ibintu bitandukanye. Umuco waryo ni uko rishobora gukurura urumuri rw'ibintu kugira ngo ritange urumuri, ku buryo ibintu byanduye bigira ingaruka nk'iz'urumuri rw'urumuri, ku buryo amaso ashobora kubona ko ibintu ari umweru cyane.

gukoresha

Ibisobanuro bya mbere by’imitekerereze ku bijyanye n’urumuri byaje mu 1852, ubwo Stokes yatangaga igitekerezo cyaje kwitwa itegeko rya Stokes. Mu 1921, Lagorio yabonye ko ingufu zigaragara z’urumuri zitangwa n’irangi ry’urumuri zari nkeya ugereranyije n’imbaraga zigaragara z’urumuri zinjiramo. Kubera iyo mpamvu, yasanze amarangi y’urumuri afite ubushobozi bwo guhindura urumuri rutagaragara rwa ultraviolet mo urumuri rugaragara. Yanasanze kandi umweru w’imigozi karemano ushobora kunozwa binyuze mu kuyakoresha umuti w’amazi w’ikintu gitanga urumuri. Mu 1929, Krais yakoresheje ihame rya Lagorio kugira ngo yemeze ko rayon y’umuhondo yari yinjijwe mu gisubizo cya 6, 7-dihydroxycoumarin glycosyl. Nyuma yo kumisha, byagaragaye ko umweru wa rayon warushijeho kuba mwiza cyane.
Iterambere ryihuse ry’ibikoresho byerekanisha urumuri byatumye bamwe mu bantu babishyira mu byiciro bitatu by’ingenzi byagezweho mu nganda z’irangi mu mpera z’ikinyejana cya 20, bitewe n’uko irangi ryakoreshejwe mu guhindura ibara ry’uruhu (reactive colors) n’ibara ry’umwimerere rya DPP.
Inganda nyinshi zatangiye gukoresha ibikoresho byo gukamura urumuri nk'impapuro, pulasitiki, uruhu, isabune. Muri icyo gihe kandi, mu nzego nyinshi zigezweho, harimo no gukoresha ibikoresho byo gukamura urumuri nk'ibi: gupima urumuri, gukoresha laser y'irangi, gucapa ibitari ibyangobwa, n'ibindi, ndetse no gufotora ahantu harehare cyane hamwe na filimi ifite ubushobozi bwo kuvura cyane kugira ngo hongere ubushobozi bwo gukamura urumuri rw'amafoto, bizanakoresha ibikoresho byo gukamura urumuri nk'ibi.

gupakira no gutwara

B. Iki gicuruzwa gishobora gukoreshwa, 25KG, 200KG, 1000KGBAERRLS.
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.
