He maha ngā whakaaturanga ote kore pumau o te emulsionte whakapūpū, te whakakotahitanga, te whakarōpūtanga (te whakapūpū rānei), te whakakorenga matū, te hurihanga āhua me te whakamāoatanga Ostwald.
1. Te Whakahekenga
Ka huihui ngā pata marara i roto i te emulsion hei hanga i ngā tautau pata toru-ahu, e tautuhia ana ko ngā floc, ā, ka kiia tēnei tukanga he flocculation. I raro i ngā āhuatanga noa, kāore he huringa nui o te rahi me te tohatoha o ngā pata i roto i ngā floc, ā, kāore e puta he hononga o ngā pata, me te pupuri tonu i ngā pata i ō rātou āhuatanga taketake. Ka puta te flocculation nā ngā kaha kukume i waenga i ngā pata. He ngoikore te nuinga o aua kaha, ka taea ai te huri i te tukanga flocculation (e mōhiotia ana ko te flocculation ngoikore), ā, mā te whakaoho ka taea te wehewehe i ngā floc.
2.Te whakakotahitanga
Ki te whakakotahi ngā pata wai o ngā pata wai, ka pakaru ngā kiriata wai o ngā pata wai ririki i roto, ka hanga he pūwero wai nui ake. Ka tautuhia tēnei tukanga ko te whakakotahitanga. He tukanga kore e taea te hoki whakamuri te whakakotahitanga, e hua ake ai te whakaiti i te maha o ngā pata wai me te pakaru katoa o ngā wairewa, arā, te wehenga hinu-wai. Ko te whakakotahitanga te tīmatanga o te whakakotahitanga, ko te whakakotahitanga ia te tino take o te kino o te wairewa.
3.Whakarōpūtanga
Nā te rerekētanga o te mātotoru i waenga i te āhua hinu me te āhua wai, ka mānu, ka totohu rānei ngā pata i raro i te mahi a te kaha ā-papa, ka whakatū he pikinga kukū pata taurite i roto i te emulsion. E mōhiotia ana tēnei tukanga ko te whakakirimi, te whakapūpū rānei. Ahakoa ka whakararu te whakakirimi i te ōritetanga o te emulsion, kāore te emulsion tonu i tino whakangaromia.
He pūnaha kore pumau te whakapūhui irahiko, ā, ko tōna āhua taurite mutunga ko te wehenga me te whakarōpūtanga o te hinu-wai (pēnei i te paparanga wai me te paparanga hinu), ā, ko te whakakorenga te hua e kore e taea te karo. I roto i ētahi mara ahumahi, me whakakorenga te whakapūhui. Hei tauira, ko te whakakorenga i te hinu mata (W/O) hei whakatutuki i te wehenga hinu-wai.
5. Rerekētanga
Ka taea e te emulsion te huri mai i te momo W/O ki te momo O/W, te huri rānei i te ritenga kē, nā runga i ngā panonitanga o ngā tikanga emulsification, ā, e mōhiotia ana tēnei tukanga ko te hurihanga ā-wāhanga.
6. Te whakamāoatanga o Ostwald
Ka taea e ngā emulsions me ngā pata o ngā rahi rerekē (ngā emulsions polydisperse) te noho pumau, ā, ka ātete ki te flocculation, ki te coalescence rānei. Heoi, i roto i te wā, ka neke te tohatoha rahi o te pata ki ngā pata nui ake, ka kukū ake te pihi tohatoha rahi o te pata, ā, ka ōrite te rahi o ngā pata. Ko tēnei āhuatanga, he rite ki te tukanga o te whakamātau tioata, ka kiia ko te whakamātau Ostwald.
