Nigute Wakwirinda ko Sulfure Ibara ry'Umukara ry'Ubwoya bw'Ipamba?

Amarangi ya sulphur akoreshwa cyane cyane mu gusiga irangi ku myenda ya kotoni, ndetse no ku myenda yavanzwe n'ipamba/vinyl. Ashongeshwa muri sodium sulfide kandi ni amahitamo meza ku bicuruzwa byijimye bya selulose, cyane cyane kuri Sulphur Black 240% na Sulphur Blue 7. Irangi rya sulphur ntaho rihuriye n'imyenda, kandi imiterere yaryo irimo imigozi ya sulphur (-S-), imigozi ya disulfide (-SS) cyangwa imigozi ya polysulfide (-Sx-), bigabanywa na sulfhydryl groups (-SNa) bitewe n'umusemburo wa sodium sulfide reductant. Ahinduka umunyu wa sodium leuco ushongesha amazi. Leuco ifite imigozi ya selulose ifitanye isano nziza kubera molekile nini z'amarangi, zikora Van der Waals nini n'imbaraga za hydrogen zo guhuza imigozi. Nubwo ibara ry'irangi rya sulphur ritari ryuzuye, ahanini ni ubururu n'umukara, ibara ntirirabagirana, ariko ikorwa ryaryo ni ryoroshye, igiciro ni gito, uburyo bwo kurisiga ni bworoshye, guhuza amabara biroroshye, kandi kwihuta kw'amabara ni byiza. Ariko, ni ngombwa kumenya ko amwe mu mabara ya sulphur, nka sulphur umukara, ashobora gutuma ipamba rikomera.

Ubushyuhe bw'umunyu bugomba kwitabwaho nyuma yoUmukara wa Sulfure 240%Irangi rikoreshwa mu gusiga irangi. Hari ibintu bimwe na bimwe bishobora kongera ibyago byo kwangirika kwa fibre, nko gukoresha cyane irangi, ibyo bikaba byongera amahirwe yo kwangirika gusa, ahubwo binagabanya kwihuta kw'ibara kandi bigatuma kumesa bigorana. Byongeye kandi, nyuma yo gusiga irangi, rigomba kozwa neza kugira ngo hirindwe kozwa nabi, kandi ibara rireremba ku budodo ryoroshye kubora rikavamo aside sulfure mu gihe cyo kubika, ibyo bigatuma fibre icika intege.

Kugira ngo ugabanye cyangwa wirinde ko fibre irushaho kumera nabi, ingamba zikurikira zishobora gufatwa:

1. Gabanya igipimo cy'irangi ry'umukara rya sulfure: igipimo cy'irangi ry'ibara ryihariye rya mercerizing ntikigomba kurenza 700 G/ipaki.

2. Nyuma yo gusiga irangi, oza neza n'amazi kugira ngo ibara rireremba ritabora rikaba aside sulfure mu gihe cyo kubika.

3. Koresha imiti igabanya ubukana bw'ibinure, nka urea, soda ash, sodium acetate, n'ibindi.

4. Uburemere bw'ubudodo bwakuwe mu mazi ni buke ugereranyije n'ubudodo bwakuwe mu mazi.

5. Kumisha ubudodo bwaranzwe ku gihe kugira ngo wirinde gushyuha kw'ubudodo butose mu gihe cyo kubuteranya, bigatuma ingano ya pH igabanuka.
