Kugaragara kwasulfure umukarani umukara flaky kristal, kandi hejuru ya kristu ifite urwego rutandukanye rwumucyo (impinduka hamwe no guhindura imbaraga). Umuti wamazi ni amazi yumukara, kandi umukara wa sulfuru ugomba gushonga hakoreshejwe sodium sulfide.
Porofeseri yumukara wa kirisiti ni irangi ryogukora ryumuryango wamabara ya sulfuru. Bikunze gukoreshwa mubikorwa byimyenda yo gusiga irangi rya pamba kuko itanga ibara ryirabura ryimbitse. Sulfide Black Crystal izwiho kwihuta kwamabara, bivuze ko itazashira na nyuma yo gukaraba inshuro nyinshi cyangwa guhura nizuba. Ihenze kandi iraboneka cyane ku isoko.
uburyo bwo gukuramo umukara wa sulfure bushingiye kuri 2,4-dinitrochlorobenzene, ihindurwamo hydrolyz mu bihe bya alkaline kugira ngo ibone umunyu wa sodium 2,4-dinitrophenol, hanyuma wongerwe ku gisubizo cya sodium polysulfide yo kwanduza ibirunga. Nyuma ya okiside, kuyungurura, Ibicuruzwa byarangiye byumye.
Umukara wa sufuru ukoreshwa cyane cyane mu gusiga irangi ipamba, ikivuguto, viscose hamwe nigitambara kivanze. Byinshi mu bitambaro bya denim (umukara) bizwi cyane mu gihugu no hanze yacyo bikozwe mu budodo bwirabura bwirabura hamwe nintambara yera. Umukara wa sufuru ufite imigozi myinshi ya disulfide nyuma yo kugabanywa na sodium sulfide, kandi biroroshye guhinduka okiside kugirango ugabanye imbaraga zimyenda irangi, ni ukuvuga ubugome. Kugirango wirinde kwangirika kwangiritse, ugomba kwitondera izi ngingo:
1 、 Kugenzura ingano ya sulfure yirabura. Ubwinshi bwumukara wa sulfure, niko byangirika cyane.
2 ash Gukaraba neza kugirango ugabanye ibara rireremba ku mizigo.
3 、 Koresha inyongeramusaruro za Taikoo kugirango wirinde kwinjiza.
4 、 Gukubita n'amazi meza mbere yo gusiga irangi. Urudodo rwanditswemo n'amazi yo kwipimisha nyuma yo gusiga irangi rufite urwego rwiza rwo kwinjiza kuruta lye.
5 Kuma mugihe nyuma yo gusiga irangi kugirango ugabanye ibikubiye mu mfashanyo zirwanya ubukana ziterwa no kwirundanya.
