Ngenxa yokunyibilika okuphantsi kwezinto ezithile eziqinileyo emanzini, xa enye okanye ezininzi zezi zinto ziqinileyo zikhona ngobuninzi kwisisombululo samanzi kwaye zishukunyiswa ngamandla e-hydraulic okanye angaphandle, zinokubakho kwimeko ye-emulsification ngaphakathi kwamanzi, zenze i-emulsion. Ngokwethiyori, inkqubo enjalo ayizinzanga. Nangona kunjalo, xa kukho ii-surfactants (ezifana namasuntswana omhlaba), i-emulsification iba nzima, nto leyo eyenza kube nzima nangakumbi ukuba la manqanaba mabini ahlukane. Oku kubonwa kakhulu kwimixube ye-oyile namanzi ngexesha lokwahlulwahlulwa kwe-oyile namanzi nakwimixube ye-oyile yamanzi kunyango lwamanzi amdaka, apho izakhiwo zamanzi-kwi-oyile okanye ze-oyile-kumanzi zenzeka phakathi kwala manqanaba mabini. Isiseko sethiyori sale meko "sisakhiwo esineengqimba ezimbini."
Kwiimeko ezinjalo, iikhemikhali ezithile ziyaziswa ukuze ziphazamise isakhiwo esizinzileyo esinamaleko amabini kwaye ziphazamise inkqubo ye-emulsified, ngaloo ndlela zifezekisa ukwahlukana kwala manqanaba mabini. Ezi arhente, ezisetyenziselwa ngokukodwa ukuqhekeza ii-emulsions, zibizwa ngokuba zii-demulsifiers.
I-demulsifier yinto esebenza ngaphezulu ephazamisa ulwakhiwo lolwelo oluxutyiweyo, ngaloo ndlela yahlula izigaba ezahlukeneyo ngaphakathi kwe-emulsion. ibhekisa kwinkqubo yokusebenzisa isenzo seekhemikhali se-demulsifiers ukwahlula ioyile namanzi kumxube weoyile namanzi e-emulsified, ukufikelela ekuphelelweni kwamanzi kwioyile ekrwada ukuze kuhlangatyezwane nemigangatho yomxholo wamanzi afunekayo ekuthuthweni.
Indlela esebenzayo necacileyo yokwahlula izigaba ze-organic kunye ne-aqueous kukusebenzisa ii-demulsifiers ukuphelisa i-emulsification kunye nokuphazamisa ukwakheka kojongano lwe-emulsification oluqinileyo, ngaloo ndlela kufezekiswa ulwahlulo lwesigaba. Nangona kunjalo, ii-demulsifiers ezahlukeneyo zahlukile kubuchule bazo bokususa izigaba ze-organic, kwaye ukusebenza kwazo kuchaphazela ngokuthe ngqo ukusebenza kakuhle kolwahlulo lwesigaba.
Kwimveliso yepenicillin, inyathelo elibalulekileyo libandakanya ukukhupha ipenicillin kumhluzi we-fermentation kusetyenziswa isinyibilikisi se-organic (esifana ne-butyl acetate). Ngenxa yokuba kukho izinto ezintsonkothileyo kumhluzi we-fermentation.—njengeeproteni, iiswekile, kunye ne-mycelia—unxibelelwano phakathi kwezigaba ze-organic kunye nezamanzi alucaci, nto leyo eyenza ummandla we-emulsification ephakathi, nto leyo echaphazela kakhulu isivuno semveliso yokugqibela. Ukujongana noku, kufuneka kusetyenziswe ii-demulsifiers ukuze kuphulwe i-emulsion, kususwe imeko ye-emulsified, kwaye kufezekiswe ukwahlukana kwesigaba ngokukhawuleza nangokusebenzayo.
