Ibikoresho
Ibikoresho nyamukuru byubukanishi bwo gutegura emulisiyo ni imashini ya emulisiyonike, ni ubwoko bwibikoresho bya emulisile byo kuvanga amavuta namazi neza. Kugeza ubu, hari ubwoko butatu bwingenzi bwimashini ya emulisifike: kuvanga emulisitiya, urusyo rwa colloid na homogenizer. Imashini yimashini yubwoko nuburyo, imikorere nubunini bwibice bya emulsiyo (dispersion) hamwe nubwiza bwa emulsion (stabilite) bifite isano ikomeye. Mubisanzwe, nkubu ubu bikoreshwa cyane muruganda rwo kwisiga rukurura emulifisiyeri, emulisiyo ikorwa no gutatanya nabi. Ibice binini kandi binini, bifite umutekano muke kandi byanduye byoroshye. Ariko gukora kwayo biroroshye, igiciro kirahendutse, mugihe cyose witaye kumiterere yimashini ikwiye, koresha neza, ariko kandi irashobora gutanga umusaruro rusange wubwiza rusange bwo kwisiga buzwi. Urusyo rwa colloid na homogenizer nibikoresho byiza byo kwigana. Mu myaka yashize, imashini ya emulisiyasi yateye imbere cyane, nka mashini ya vacuum emulisifike, emulisiyo yateguwe no gutatana no gutuza kwiza.
Ubushyuhe
Ubushyuhe bwa emulisifike bugira uruhare runini kuri emulisation, ariko nta karimbi gakabije kubushyuhe. Niba amavuta n'amazi bitemba, birashobora kwiganwa no gukurura ubushyuhe bwicyumba. Mubisanzwe, ubushyuhe bwa emulisiyoneri buterwa no gushonga kwibintu bifite aho bishonga cyane mubice bibiri, kandi hagomba gutekerezwa kubintu nkubwoko bwa emulisiferi hamwe nubushyuhe bwicyiciro cya peteroli nicyiciro cyamazi. Byongeye kandi, ubushyuhe bwibyiciro byombi bugomba guhora hafi kimwe, cyane cyane kubice by ibishashara nibinure byamavuta hamwe no gushonga cyane (hejuru ya 70 ℃), mugihe emulisitiya, icyiciro cyamazi yubushyuhe ntigomba kongerwaho, kugirango irinde ibishashara n'ibinure gutobora mbere ya emulisiyasi, bikavamo emulisiyo nini cyangwa yuzuye kandi itaringaniye. Muri rusange, iyo emulisile, ubushyuhe bwamavuta namazi birashobora kugenzurwa hagati ya 75 ℃ na 85 ℃. Niba icyiciro cya peteroli gifite ibishashara bishonga hamwe nibindi bice, ubushyuhe bwa emulisitiya buzaba hejuru muriki gihe. Byongeye kandi, niba ibibyimba byiyongera cyane muburyo bwa emulisifike, ibyo bita umubyimba mwinshi kandi bigira ingaruka ku kuvanga, ubushyuhe bwa emulisation burashobora kuzamurwa muburyo bukwiye. Niba emulifier ikoreshwa ifite ubushyuhe bwinzibacyuho runaka, ubushyuhe bwa emulisile nabwo bwatoranijwe neza hafi yubushyuhe bwinzibacyuho. Ubushyuhe bwa Emulisation rimwe na rimwe bugira ingaruka no ku bunini bwa emulsiyo. Niba anionic emulisiferi yisabune ya acide ya acide ikoreshwa muri rusange, ingano ya emulsiyo igera kuri 1.8-2.0 mm iyo ubushyuhe bwa emulisiyonike bugenzuwe kuri 80 ℃. Niba ingano yingero zingana na 6μm mugihe emulisation ikorwa kuri 60 ℃. Ingaruka yubushyuhe bwa emulisiyonike ku bunini bwingingo iba ifite intege nke iyo emulisiferi itari ionic ikoreshwa muri emulisifike.
Guhindura igihe
Igihe cya Emulisifike biragaragara ko kigira ingaruka kumiterere ya emulsiyo, kandi kugena igihe cyo gusohora ni ukurikije ingano yubunini bwikiciro cyamazi yicyiciro cyamazi, ibyiciro bibiri byijimye kandi bikabyara ubwiza bwa emulsiyo, ubwoko na dosiye ya emulisiferi, emulisitiya ubushyuhe, kwigana igihe kingana kangahe, birahagije kugirango sisitemu ya emulisifike, ifitanye isano rya bugufi nubushobozi bwibikoresho bya emulisation, igihe cya Emulisation gishobora kugenwa ukurikije uburambe nubushakashatsi. Emulisation hamwe na homogenizer (3000 RPM) bifata iminota 3-10 gusa.
Kuvanga umuvuduko
Ibikoresho bya Emulisifike bigira uruhare runini kuri emulisation, imwe murimwe ningaruka zo gukurura umuvuduko kuri emulisation. Umuvuduko uringaniye ni ugukora icyiciro cyamavuta nicyiciro cyamazi kivanze rwose, umuvuduko muke cyane, biragaragara ko udashobora kugera ku ntego yo kuvanga byuzuye, ariko umuvuduko mwinshi cyane, bizazana ibibyimba muri sisitemu, kuburyo bihinduka bitatu- icyiciro cya sisitemu, kandi utume emulion idahinduka. Kubwibyo, umwuka ugomba kwirinda kuvanga, kandi imashini ya emulisifike ya vacuum ifite imikorere isumba izindi.
