Kune zviratidzo zvakawanda zvekusagadzikana kwe emulsion: kuyerera, kubatana, kupatsanurwa (kana kuumbwa kwevhu), kubviswa kwemusanganiswa wemvura, kuchinjika kwechikamu uye kuibva kweOstwald.
1. Kuyerera kwemvura
Madonhwe akapararira ari mu emulsion akabatana kuita mapoka emadonhwe ane mativi matatu, ayo anotsanangurwa se flocs, uye maitiro aya anonzi flocculation. Mumamiriro ezvinhu akajairwa, hapana shanduko huru muhukuru nekupararira kwemadonhwe mukati me flocs, uye madonhwe haasanganiswi, madonhwe achiramba aine hunhu hwawo hwepakutanga. Flocculation inokonzerwa nemasimba anokwezva ari pakati pemadonhwe. Masimba akadaro anowanzova asina simba, zvichiita kuti maitiro e flocculation adzokereke (anozivikanwa se weak flocculation), uye kuvhunduka kunogona kuparadzanisa flocs.
2.Kubatana
Kana madonhwe eflocculates akabatana, mafirita emvura emadonhwe madiki ari mukati anoputika oita mabhora makuru emvura. Maitiro aya anotsanangurwa sekubatana. Kubatana inzira isingadzoreki, iyo inotungamira kukudzikira kwehuwandu hwemadonhwe uye kuputsika kwakakwana kwe emulsions, kureva kuparadzaniswa kwemafuta nemvura. Kubatana kunoshanda senzira yekutanga kubatana, nepo kubatana kuri iko kunokonzera zvakananga kukuvara kwe emulsion.
3.Kupatsanurwa kwezvikamu
Nekuda kwemusiyano wekuwanda kwemafuta nechikamu chemvura, madonhwe anoyangarara kana kunyura pasi pesimba regiravhiti, zvichigadzira mwero wehuwandu hwemadonhwe mu emulsion. Maitiro aya anozivikanwa se creaming kana sedimentation. Kunyangwe creaming ichikanganisa kufanana kwe emulsion, emulsion pachayo haina kuparadzwa zvechokwadi.
4.Kubviswa kwemusanganiswa wemafuta
Emulsion sisitimu isina kugadzikana yethermodynamic ine mamiriro ekupedzisira ekuenzana kwemafuta nemvura uye kupatsanurwa (senge aqueous layer neoil layer), uye demulsification ndiwo mhedzisiro yayo isingadzivisike. Mune mamwe maindasitiri, demulsification inodiwa. Semuenzaniso, demulsifying crude oil (W/O) kuti uwane kupatsanurwa kwemafuta nemvura.
5.Musiyano
Emulsion inogona kushanduka kubva kumhando yeW/O kuenda kumhando yeO/W, kana kuti zvinopesana, nekuda kwekuchinja kwemamiriro e emulsification, uye maitiro aya anozivikanwa se phase inversion.
6. Kuibva kweOstwald
MaEmulsion ane madonhwe ehukuru hwakasiyana (polydisperse emulsions) anogona kuramba akasimba uye achiramba kutenderera kana kubatana. Zvisinei, nekufamba kwenguva, kupararira kwehukuru hwemadonhwe kunochinja kuenda kumadonhwe makuru, curve yekupararira kwehukuru hwemadonhwe inova yakabatana zvakanyanya, uye hukuru hwemadonhwe hunowanzova hwakafanana. Chiitiko ichi, chakafanana nemaitiro ekuibva kwekristaro, chinonzi Ostwald ripening.
