Mu buzima bwa buri munsi, ese wigeze wibaza impamvu amwe mu masabune yo kumesa imyenda ashobora gutuma imyenda yera ikomeza "gutangara" nyuma yo kumesa, nk'aho yavuguruwe? Ibi ni ukubera ibikoresho by'umwimerere byitwa "optical brightener agent CBS-X." Iyi kristalo yera isa n'isanzwe mu by'ukuri ni "ifu y'ubumaji" y'ingenzi mu nganda za shimi za buri munsi. Muri iki gihe, yabaye ingenzi mu nganda zikora ibidukikije bitewe n'imikorere yayo myiza mu bidukikije.

Ni ikiimashini ikoresha urumuri CBS-X?

CBS-X, izwi kandi nka disodium stilbene-biphenyl disulfonate, ni icyuma gitanga urumuri cya stilbene-biphenyl. Ihame ryayo ntabwo ari "guhindura umweru" gakondo, ahubwo ni uko ifata urumuri rutagaragara rwa ultraviolet rukayihindura urumuri rworoshye rugaragara rw'ubururu-violet. Uru mucyo w'ubururu wuzuza urumuri rw'umuhondo rw'imyenda ubwayo, bigatuma umweru mwinshi cyane n'urumuri birushaho kuba byiza, bigatuma imyenda ishaje isa neza nk'aho ari "ishya mu ruganda".

Mu buryo bw'umubiri,CBS-XUbusanzwe igaragara nk'ifu cyangwa uduce duto tw'umuhondo-icyatsi kibisi dufite ubushobozi bwo gushonga neza mu mazi: ubushobozi bwayo bwo gushonga mu mazi akonje kuri 25°C bushobora kugera kuri 25g/L, mu gihe ubushobozi bwayo bwo gushonga mu mazi ashyushye kuri 95°C buzamuka bukagera kuri 300g/L, bigatuma yoroshye kuyikoresha mu buryo butandukanye bwo gukaraba nko gukaraba mu buryo bukonje n'ubushyuhe.

"Umunyeshuri wa mbere" mu basukura

Mu nganda zikora isuku yo kumesa imyenda, CBS-X ivugwa nk'imwe mu "brighteners nziza z'amatara." Gukundwa kwayo bikomoka ahanini ku byiza by'ingenzi bikurikira:

1. Igipimo gito, ingirakamaro cyane: CBS-X ifite imbaraga zikomeye cyane zo kumesera. Kongeramo 0.05%-0.2% gusa mu isabune yo kumesa imyenda cyangwa ifu bitanga umusaruro mwiza wo kwera. Ugereranyije n'imiti gakondo ya stilbene triazine optical brightener, imikorere yayo myiza bivuze ko ikiguzi rusange n'umutungo bigabanuka.

2. Irahamye cyane: Iki gicuruzwa kirwanya cyane chlorine bleach na aside na alkali, kigumana neza no mu bidukikije birimo sodium hypochlorite, bikagishyira mu cyiciro cy’ibirabagirana bidahinduka bleach. Ibi bivuze ko mu gihe cyo kumesa inshuro nyinshi, gishobora kurabagirana imyenda nta muhondo cyangwa ibara ryayo.

3. Ubufatanye bwa fibre bugari: CBS-X igira ingaruka nziza ku migozi ya cellulosic (nk'ipamba), polyamides (nk'iyi nylon), na poroteyine (nk'ubwoya n'ubudodo) haba ku bushyuhe bw'icyumba ndetse no ku bushyuhe bwinshi, bigatuma irushaho kuba nziza cyane.

Ingingo z'ingenzi: Gukorera hamwe mu kubungabunga ibidukikije

Mu gusubiza impungenge z'abaguzi ku bijyanye no kubungabunga ibidukikije kw'ibikoresho by'ikoranabuhanga bitanga urumuri, CBS-X, hamwe n'ibice byayo byita ku bidukikije, yashyizeho igipimo gishya ku nganda.

Yoroshye kubora no gusubira mu bidukikije,
byakozwe mu buryo bugezwehoCBS-XIfite imikorere myiza cyane mu bidukikije. Yoroherwa no kwangirika kandi ntihumanya ibidukikije mu gihe ikoreshwa, ihaza byuzuye ibyifuzo byihutirwa bya sosiyete ya none ku bicuruzwa bitangiza ibidukikije n'ibitekerezo by'iterambere rirambye. Hari n'ibicuruzwa bimwe na bimwe bisobanurwa mu buryo butaziguye nk'ibicuruzwa bitangiza ibidukikije bitewe n'ingano yabyo y'uduce duto.

Umutekano wa CBS-X umaze igihe kinini uzwi ku isi yose, nk'uko byemejwe n'amategeko mpuzamahanga
Yatsindiye ibyemezo by’ibigo bipima mu Bushinwa, muri Leta Zunze Ubumwe za Amerika, mu Buyapani no mu Muryango w’Ubumwe bw’u Burayi. Ishyirahamwe ry’inganda z’ibicuruzwa byo gusukura mu Bushinwa naryo ryasohoye inyandiko ku miyoboro yemewe itanga ibisobanuro birambuye ku mutekano w’ibikoresho bitanga urumuri.

Nta bintu bibujijwe bikoreshwa, bikurinda ubuzima bwawe:

CBS-XMolekile ntizirimo chlorine kandi ntizitera kanseri. Ibipimo by'ubwiza bwayo bigenzurwa neza ku bipimo bya amine zangiza n'ibyuma bikomeye, bigamije umutekano ku bantu ku gipimo cyagenwe n'ikoreshwa rusange. Yemerewe no kugera ku biribwa, birushaho kugaragaza umutekano wayo mwiza.

Uretse "gutunganya" gusa, ni amahitamo arambye.

Mu gusubiza impungenge zagaragajwe na bamwe mu baguzi ku bijyanye n'umutekano w'ibikoresho bitanga urumuri, impuguke mu nganda zatanze ibisubizo bisobanutse. Mu ntangiriro za 2008, ibipimo ngenderwaho by'inganda QB/T 2953-2008 byashyize ahagaragara neza stilbene biphenyls (CBS-X) nk'icyiciro cyemewe gukoreshwa mu isabune yo kumesa imyenda. Byongeye kandi, raporo y'isuzuma ry'ingaruka zavuye mu Ishyirahamwe ry'Uburayi rishinzwe kumesa imyenda (AISE) nayo igaragaza ko CBS-X ikoreshwa mu isabune itazagira ingaruka mbi ku buzima bw'abantu cyangwa ibidukikije.

Mu rwego rw’ibidukikije, ubushobozi bwa CBS-X bwo gukora neza bivuze ko ari ingano ntoya cyane—hakenewe ingano nto cyane kugira ngo hagerwe ku ngaruka zifuzwa, ibyo bikaba bigabanya mu buryo butaziguye ikoreshwa ry’ibikoresho fatizo bya shimi ndetse n’ingaruka z’inganda ku bidukikije.

Ishusho y'Isoko: Umuraba w'Ibidukikije Utera Iterambere

Kubera ko abaguzi ku isi barushaho gusaba “isuku” no “kubana neza n’ibidukikije,” isoko ry’ibikoresho by’ikoranabuhanga birimo kwiyongera. Dukurikije ubushakashatsi bw’isoko, ingano y’isoko rya CBS-X rishobora kuzungukira mu gushaka cyane kw’inganda zikora imyenda n’imashini zisukura, kandi amahirwe yaryo ni meza.

Isosiyete yacu yihariye mu kohereza hanze ibikoresho byo gukaraba amatara kandi ifite uburambe bw'imyaka irenga icumi. Niba ufite ikibazo kuriibikoresho byo gukamura urumuri,wisanzuye kubikoraTwandikire.
