Hari ibimenyetso byinshi byerekanakudakomera kwa emulsion: gukurura, guhuza, gushyira mu byiciro (cyangwa gusya), gukuramo ibinyabutabire mu buryo bwa "demulsification", guhindura ibice no gukura kwa Ostwald.
1. Gutera amazi mu mazi
Ibitonyanga bitatanye muri emulsion bihurira hamwe bigateranya ibitonyanga by’ibipimo bitatu, bisobanurwa nka flocs, kandi iyi nzira yitwa flocculation. Mu bihe bisanzwe, nta mpinduka zikomeye ziba mu bunini n’uburyo ibitonyanga bikwirakwira muri flocs, kandi ibitonyanga ntibibaho, aho ibitonyanga bigumana imiterere yabyo y’umwimerere. Flocculation iterwa n’imbaraga zikurura hagati y’ibitonyanga. Izi mbaraga akenshi ziba zidakomeye, bigatuma inzira yo flocculation isubira inyuma (izwi nka flocculation idakomeye), kandi guhindagurika bishobora gutandukanya flocs.
2.Ubwiyunge
Iyo ibitonyanga bya flocculates bihuye, imiterere y'amazi y'ibitonyanga bito imbere iracika maze igakora amasaro manini y'amazi. Iyi nzira isobanurwa nk'ihuza. Ihuza ni inzira idasubira inyuma, ituma umubare w'ibitonyanga ugabanuka kandi ihuza ryuzuye rya emulsion, ni ukuvuga gutandukana kw'amavuta n'amazi. Ihuza ry'amazi ribera nk'intangiriro y'ihuza ry'amazi, mu gihe ihuza ry'amazi ari yo mpamvu itaziguye yangiza emulsion.
3.Gushyira mu byiciro
Bitewe n'itandukaniro ry'ubucucike hagati y'icyiciro cy'amavuta n'icyiciro cy'amazi, ibitonyanga bizareremba cyangwa bigashira bitewe n'imbaraga rukuruzi, bigashyiraho urugero rw'ibitonyanga muri emulsion. Iyi nzira izwi nka creaming cyangwa sedimentation. Nubwo creaming yangiza imiterere ya emulsion, emulsion ubwayo ntabwo yangirika by'ukuri.
Emulsion ni sisitemu idahindagurika mu buryo bwa thermodynamic, aho uburinganire bwayo bugarukira ku gutandukanya amavuta n'amazi no kuyatandukanya (nk'urwego rw'amazi n'urwego rw'amavuta), kandi gukuramo amazi ni yo ngaruka idashobora kwirindwa. Mu nganda zimwe na zimwe, gukuramo amazi ni ngombwa. Urugero, gukuramo amavuta mabi (W/O) kugira ngo habeho gutandukanya amavuta n'amazi.
5. Impinduka
Emulsion ishobora guhinduka kuva kuri W/O ikajya kuri O/W, cyangwa se bitewe n'impinduka mu miterere ya emulsification, kandi iyi nzira izwi nka phase inversion.
6. Ostwald ishaje
Emulsion zifite ibitonyanga by’ingano zitandukanye (polydisperse emulsions) zishobora kuguma zihamye kandi zigatuma zidashobora guhindagurika cyangwa guhurirana. Ariko, uko igihe kigenda gihita, ingano y’ibitonyanga irahinduka ikajya ku bitonyanga binini, ingano y’ibitonyanga irushaho kuba nyinshi, kandi ingano y’ibitonyanga ikunze kuba imwe. Iki kintu, kimwe n’uburyo bwo gukura kw’ibirori, cyitwa Ostwald ripening.
