Igikorwa cyo kubyaza umusaruro kirimo: gushyushya ubushyuhe bwa bitumen nigisubizo cyisabune, guhindura igisubizo cyisabune pH agaciro, no kugenzura umuvuduko wa buri muyoboro mugihe cyo gukora.
(1) Ubushyuhe bwa bitumen n'umuti w'isabune
Bitumen ikeneye kugira ubushyuhe bwo hejuru kugirango igere kumurongo mwiza. Iseswa rya emulisiferi mumazi, kongera ibikorwa byogusukura amasabune ya emulisiferi, no kugabanya umuvuduko wamazi-bitumen bisaba intera isabune kuba mubushyuhe runaka. Mugihe kimwe, ubushyuhe bwa emulisile bitumen nyuma yumusaruro ntishobora kuba hejuru ya 100 ℃, bitabaye ibyo bizatera amazi kubira. Urebye ibyo bintu, ubushyuhe bwa bitumen bwatoranijwe kuba 120 ~ 140 ℃, ubushyuhe bwumuti wamasabune ni 55 ~ 75 ℃, naho ubushyuhe bwa bitumen bwasohotse ntabwo buri hejuru ya 85 ℃.
(2) Guhindura igisubizo cyisabune pH agaciro
Emulifiyeri ubwayo ifite acide na alkaline runaka kubera imiterere yimiti. Emulisifike ya Ionic ishonga mumazi kugirango ikore igisubizo cyisabune. Agaciro pH kagira ingaruka kumikorere ya emulifier. Guhindura agaciro gakwiye pH byongera ibikorwa byumuti wisabune. Emulifiseri zimwe ntizishobora guseswa utabanje guhindura pH agaciro k'isabune. Acide yongerera ibikorwa bya emulisiferi ya cationic, alkalinity yongera ibikorwa bya emulisiferi ya anionic, kandi ibikorwa bya emulisifike idafite aho bihuriye nagaciro ka pH. Iyo ukoresheje emulisiferi, agaciro ka pH kagomba guhinduka ukurikije amabwiriza yihariye y'ibicuruzwa. Acide ikoreshwa cyane na alkalis ni: aside hydrochloric, aside nitric, aside aside, aside acike, hydroxide ya sodium, ivu rya soda, nikirahure cyamazi.
(3) Kugenzura imiyoboro itemba
Umuyoboro utemba wa bitumen hamwe nisabune igena ibirimo bitumen mubicuruzwa bya emulisile. Ibikoresho bya emulisation bimaze gukosorwa, ingano yumusaruro iba isanzwe. Urujya n'uruza rwa buri muyoboro rugomba kubarwa no guhindurwa ukurikije ubwoko bwa biti ya emulisile yakozwe. Twabibutsa ko igiteranyo cyurugendo rwa buri muyoboro rugomba kungana nubunini bwa bitumen yakozwe.
