Mokhoa oa ho khetha mochini o loketseng oa emulsifying, Jeremane e rekisitse mochini oa emulsifying kantle ho naha, mochini oa emulsifying oa indasteri, mochini oa sefofane oa emulsifying
Mochini oa emulsifying o bapala karolo ea bohlokoa tsamaisong ea ho kopanya lisebelisoa tsa indasteri, haholo-holo ho tsoakang metsi a tiileng le mokelikeli.
Ho kopanya metsi, emulsification ea metsi a oli, ho hasana le homogenization, ho sila ha shear ho na le lisebelisoa tsa bohlokoa haholo. Lebaka
E bitsoa mochine oa emulsifying hobane o ka finyella emulsification. E thehiloe ka mor'a ho kopanya ka ho feletseng ha oli le metsi, lipakeng tsa mekhahlelo e 'meli
Emulsion e ka aroloa ka mekhoa e 'meli: oli ka metsing kapa oli ka metsing. Ho fihlela emulsification, bonyane ho na le litlhokahalo tse peli:
E 'ngoe ke phello e matla ea ho itšeha ea ho itšeha, karolo ea metsi le karolo ea oli ea mokelikeli ka nako e le 'ngoe e khaotsoe le ho hasana bakeng sa tse nyane.
Likaroloana, 'me joale li kopane ha ho e-na le ho kopanya ho kenella ka bobeli, ho thehoa ha emulsion. Ea bobeli ke emulsifier e nepahetseng,
E sebetsa joalo ka borokho bo mahareng lipakeng tsa oli le limolek'hule tsa metsi, 'me e etsa oli le metsi ka ts'ebetso ea tefiso ea eona ea motlakase le matla a intermolecular.
Emulsion e tla tsitsa ka nako e telele kamoo re batlang kateng.
Hona joale ts'ebeliso ea mochini oa emulsifying ha e felle feela ho "emulsification", ka lebaka la ketso ea eona e ikhethang ea ho kuta,
Likaroloana tse hahelletsoeng ka har'a tšusumetso ea mokelikeli qetellong li hloekisitsoe ho isa tekanyong e loketseng ea karoloana, e le hore thepa e tiileng e kopane ka botlalo.
Ka har'a mokelikeli 'me u thehe ho emisoa ho batlang ho tsitsitse, mokhoa ona o boetse o tsejoa e le "phatlalatso". 'Me ehlile ka emulsification
Joalo ka dispersant, botsitso ba ho fanyeha bo ka matlafatsoa ka ho eketsa dispersant. Ha ntho e tiileng
E ka qhibiliha ka ho feletseng ke mokelikeli ka nako e itseng ea ho kopana le mokelikeli, ka nako eo, e thehoa ka tšusumetso ea ho kuta
Likaroloana tse nyenyane li tla qhibiliha ka potlako hobane sebaka sa tsona se khethehileng se seholo ka makhetlo a mangata.
Ha batho ba sebelisetsoa homogenizer ea khatello e phahameng (khatello, ho lokolloa hanghang ha khatello e phahameng, phello ea jet) ho fumana
Ka mor'a ho fumana likaroloana tse ntle, "ntlafatso" e lekana le "homogenization", kahoo emulsifier e ntle ho thepa.
Mokhoa oa homogenization le ho kopanya ka ho feletseng o boetse o bitsoa homogenization. Kahoo, re ka boela ra beha emulsifier
E bitsoa homogenizer, e le ho khetholla, ka kakaretso e ka ba moqhaka ka lebelo le phahameng kapa homogenizer e phahameng, e le hore lebese.
Mochini oa lik'hemik'hale o na le mabitso a mangata: mochini o phahameng oa ho shear emulsification, mochini o phahameng oa ho homogenization oa ho kuta, mochini o phahameng oa emulsification oa ho kuta, o phahameng.

Lintho tse amang emulsification
1. Emulsifying thepa
Hona joale, ho na le mefuta e meraro e meholo ea mochine oa emulsifying: motsoako oa emulsifying, leloala la colloid le homogenizer. Emulsifying mofuta oa mochine le sebopeho, tshebetso le boholo ba likaroloana tsa emulsion (ho hasana) le boleng ba emulsion (botsitso) bo na le kamano e kholo. Emulsion e hlahisoang ke emulsifier e sisinyehang e na le dispersibility e fokolang, likaroloana tse kholo le tse mahoashe, botsitso bo fokolang le tšilafalo e bonolo. Empa tlhahiso ea eona e bonolo, theko e theko e tlaase, hafeela u ela hloko mohaho o utloahalang oa mochine, o sebelise hantle, empa hape o ka hlahisa litlhoko tse akaretsang tsa boleng ba litlolo tse ratoang. Colloid leloala le homogenizer ke lisebelisoa tse betere tsa emulsifying. Lilemong tsa morao tjena, mechine ea emulsifying e entse tsoelo-pele e kholo, e kang mochine oa vacuum emulsifying, ho hasana le botsitso ba emulsion e lokiselitsoeng ke eona e ntle haholo.
2, mocheso
Mocheso oa emulsification o na le tšusumetso e kholo ho boleng ba emulsification, empa ha ho na moeli o tiileng oa mocheso. Ka kakaretso, nakong ea emulsification, mocheso oa mekhahlelo ea oli le metsi o ka laoloa pakeng tsa 75 ℃ le 85 ℃. Sena se ipapisitse le lintlha tse joalo ka ntlha ea ho qhibiliha ea lintho tse nang le ntlha e phahameng ea ho qhibiliha, mofuta oa emulsifier le ho qhibiliha ha karolo ea oli le karolo ea metsi.
3. Emulsifying nako
Nako ea emulsification e na le phello ho boleng ba emulsion. Bolelele ba nako ea emulsifying bo amana le tekanyo ea boholo ba karolo ea oli le karolo ea metsi, viscosity ea mekhahlelo e 'meli le viscosity ea emulsion e hlahisitsoeng, mofuta le tekanyo ea emulsifier, mocheso oa emulsifying, mofuta oa emulsifier le lintlha tse ling. Hangata e khethoa ke phihlelo le liteko.
