Emulsifying lisebelisoa
Thepa e ka sehloohong ea mochine bakeng sa ho lokisetsa emulsion ke mochine oa emulsifying, e leng mofuta oa lisebelisoa tsa emulsifying bakeng sa ho kopanya oli le metsi ka ho lekana. 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. Ka kakaretso, joalo ka ha hona joale e sebelisoa haholo fekthering ea litlolo e susumetsang emulsifier, emulsion e hlahisoang ke ho hasana ha mafutsana. Likaroloana li kholo ebile li mahoashe, li na le 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, emulsion e lokiselitsoeng ke ho hasana le botsitso ba babatsehang.
Mocheso
Mocheso oa emulsification o na le tšusumetso e kholo ho emulsification, empa ha ho na moeli o tiileng oa mocheso. Haeba oli le metsi li le metsi, li ka etsoa emulsified ka ho hlohlelletsa mocheso oa kamore. Ka kakaretso, mocheso oa emulsification o itšetlehile ka ntlha ea ho qhibiliha ea lintho tse nang le ntlha e phahameng ea ho qhibiliha ka mekhahlelo e 'meli,' me lintlha tse kang mofuta oa emulsifier le ho qhibiliha ha karolo ea oli le karolo ea metsi li lokela ho nkoa. Ho phaella moo, mocheso oa mekhahlelo e 'meli o lokela ho bolokoa hoo e batlang e le o ts'oanang, haholo-holo bakeng sa likarolo tsa boka ba boka le mafura a nang le ntlha e phahameng ea ho qhibiliha (ka holimo ho 70 ℃), ha ho etsoa emulsifying, mocheso o tlase oa metsi ha oa lokela ho ekeletsoa, thibela boka le mafura hore a se ke a khanya pele ho emulsification, e leng se bakang emulsion e kholo kapa e mahoashe le e sa lekaneng. Ka kakaretso, ha ho etsoa emulsifying, mocheso oa oli le metsi o ka laoloa pakeng tsa 75 ℃ le 85 ℃. Haeba karolo ea oli e na le boka bo phahameng ba ho qhibiliha le likarolo tse ling, mocheso oa emulsifying o tla ba o phahameng ka nako ena. Ho phaella moo, haeba viscosity eketseha haholo tshebetso emulsification, ho thoeng le teteaneng haholo le ama ho kopanya, ba bang ba emulsification mocheso ka ka tsela e loketseng tsosoa. Haeba emulsifier e sebelisitsoeng e na le mocheso o itseng oa phetoho ea mohato, mocheso oa emulsifying o boetse o khethoa hantle ho potoloha mocheso oa phetoho ea mohato. Ka linako tse ling mocheso oa emulsification o boetse o ama boholo ba karoloana ea emulsion. Haeba emulsifier ea anionic ea sesepa sa mafura a mafura e sebelisoa ka kakaretso, boholo ba karoloana ea emulsion bo ka ba 1.8-2.0μm ha mocheso oa emulsification o laoloa ho 80 ℃. Haeba boholo ba karoloana bo ka ba 6μm ha emulsification e etsoa ka 60 ℃. Phello ea mocheso oa emulsification boholo ba likaroloana e fokola ha emulsifier e seng ea ionic e sebelisoa bakeng sa emulsification.
Emulsifying nako
Ho hlakile hore nako ea emulsification e na le phello ho boleng ba emulsion, 'me boikemisetso ba nako ea emulsifying ke ho ea ka tekanyo ea boholo ba karolo ea metsi, karolo ea bobeli ea viscosity le ho hlahisa viscosity ea emulsion, mofuta le litekanyetso tsa emulsifier, emulsifying. mocheso, emulsifying nako ea hore na ke ba bakae, e lekane ho etsa tsamaiso ea emulsification, e amana haufi-ufi le katleho ea lisebelisoa tsa emulsification, nako ea Emulsification e ka khethoa ho latela boiphihlelo le liteko. Emulsification ka homogenizer (3000 RPM) e nka metsotso e 3-10 feela.
Ho kopanya lebelo
Thepa ea emulsification e na le tšusumetso e kholo ho emulsification, e 'ngoe ea eona ke tšusumetso ea lebelo le susumetsang ho emulsification. Lebelo le leka-lekaneng le susumetsang ke ho etsa karolo ea oli le karolo ea metsi e kopantsoeng ka ho feletseng, lebelo le tlaase haholo le tsosang, ho hlakile hore le ke ke la finyella sepheo sa ho kopanya ka ho feletseng, empa le lebelo le phahameng haholo le susumetsang, le tla tlisa li-bubble tsamaisong, e le hore e be tse tharo- tsamaiso ea mohato, le ho etsa hore emulsion e se ke ea tsitsa. Ka hona, moea o tlameha ho qojoa ha o kopanya, 'me mochini oa vacuum emulsifying o na le ts'ebetso e phahameng haholo.
