Uburyo busanzwe bwo gusiga amarangi yimyenda yijimye

1.Kongera ubushyuhe bwo gusiga irangi
Mu kongerairangiubushyuhe, imiterere ya fibre irashobora kwagurwa, imikorere yimikorere ya molekile irangi irashobora kwihuta, kandi amahirwe yo gusiga irangi kuri fibre arashobora kwiyongera. Iyo rero dusize irangi ryijimye ryijimye, burigihe tugerageza kongera ubushyuhe bwo gusiga irangi kugirango twongere irangi. Ariko, kwiyongera kubushyuhe ubushyuhe bwo gusiga irangi bishobora guhindura imbaraga zimyenda irangi kandi birashobora no gutera ibara ryinshi ryubushyuhe cyangwa hydrolysis yamabara amwe, kimwe no gusiga irangi kumitsi. Ariko irangi-gufata amarangi amwe ryaragabanutse hamwe no kwiyongera k'ubushyuhe bwo gusiga irangi, ibyo bikaba desorption phenomenon. Kubwibyo, ntabwo ari siyanse kongera ubushyuhe bwo gusiga irangi kugirango wongere irangi.

2.Kongera urugero rwamabara
Kugirango usige irangi ryijimye, inganda zimwe na zimwe zongera urugero rwamabara kugirango igere ibara ryijimye. Bitewe n’amabara menshi, bizagorana cyane kuvura amarangi y’amazi. Kandi rimwe na rimwe, nubwo ibara ryijimye ryagezweho, iibara ryihutani umukene cyane. Ku isoko rero, hari imyenda yijimye yijimye byoroshye gushira nyuma yo gukaraba.
 
3. Ongeramo electrolyte kugirango uteze imbere irangi
Kubirangi byirangi n'amabara ataziguye, wongeyeho electrolyte, nka NaCl na Na₂SO₄, nibindi mugihe cyo gusiga irangi bizamura irangi. Amabara ya aside, wongeyeho HAC na H.₂SO₄, nibindi bizamura irangi. Ubu buryo buzamura igipimo cyo gusiga irangi no gufata irangi ku mwenda ku rugero runaka. Kandi kubwinshi bwamabara yamabara yijimye, hariho byinshi byongeweho kuzamuraumukozi.
Ariko, kongeramo electrolyte nyinshi ntabwo bizagabanya gusa ububengerane bwimyenda, ahubwo bizatera coagulation yamabara, bizatera ikibazo cyiza.
