Umthelela wezinto zokusebenza ze-emulsification ekuzinzeni kwe-emulsification kwemikhiqizo

Abakhiqizi abaningi bemikhiqizo yamakhemikhali bazonaka kakhulu ukuzinza kwe-emulsification ekuthuthukisweni kwemikhiqizo, ngoba ukuzinza kwemikhiqizo kuhlobene nekhwalithi yezimonyo. Imikhiqizo yekhwalithi ephezulu ingakha idumela lamabhizinisi, ngakho-ke abakhiqizi bezimonyo ekukhetheni kwemishini ye-emulsification nabo kufanele baqonde. Lokhu okulandelayo kwethula umthelela wemishini yokwenziwa kwe-emulsification ekuzinzeni kwe-emulsification yomkhiqizo, indlela yokukhetha okokusebenza kwe-emulsification okufanelekile?

1. Umqondo we-emulsification

I-Emulsion iyisimo esibonakalayo soketshezi oluwuketshezi, uketshezi olubili olungancibiliki, olufana nowoyela namanzi, luhlukaniswa lwaba izingqimba ezimbili esitsheni, namafutha aminyene amancane ongqimbeni olungaphezulu namanzi aminyene kakhulu engxenyeni engezansi. Uma i-surfactant efanelekile ingeziwe ngaphansi kokugqugquzela okunamandla, amafutha ahlakazeka emanzini ukuze enze i-emulsion, inqubo ibizwa ngokuthi i-emulsification.

2. Umthelela wezinto zokusebenza ze-emulsification ekuzinzeni kwe-emulsification kwemikhiqizo

Umshini wokuxuba ojwayelekile we-emulsion, ukuhlakazeka nokuzinza kwe-emulsion kumpofu, futhi izinhlayiya zinkulu futhi zilukhuni, ukuzinza nakho kumpofu, kodwa futhi kulula kakhulu ukukhiqiza ukungcola. Ngakho-ke, ikhwalithi yezimonyo ezikhiqizwayo ingase ibe yinto evamile, futhi isipiliyoni samakhasimende ngeke sibe sihle kakhulu.
Ukuqina komkhiqizo oqediwe jikelele kubi kakhulu, ikhwalithi ayinhle kangako, ingenza kuphela imikhiqizo esezingeni eliphansi ngobuchwepheshe obulula. Lokhu akusizi ekuthuthukisweni kwesikhathi eside kwamabhizinisi.

3. Vacuum homogenization kanye emulsification umshini

Ngokuthuthukiswa kobuchwepheshe be-emulsification eminyakeni yamuva, umshini we-Zhitong wethule ngenkuthalo ubuchwepheshe bokukhiqiza angaphandle, wasungula futhi wakhiqiza umshini we-vacuum homogeneous emulsification ukuze wamukelwe futhi usekelwe amakhasimende awo.
Vacuum homogenization emulsifying umshiniisethi ephelele yesistimu ehlanganisa ukuxuba, ukuhlakazeka, i-homogenization, i-emulsification kanye nokumuncwa kwempushana. Ngokusebenzisa amandla anamandla e-kinetic alethwa umshini, izinto ezisesikhaleni esincane se-rotor kanye ne-stator, zingamelana namakhulu ezinkulungwane ze-liquid force shear njalo ngomzuzu, imikhiqizo e-emulsifying esheshayo.
Ungakhathazeki ngemikhiqizo esenqubo yokukhiqiza emoyeni, yenza imikhiqizo ibe amabhamuza, ukungcoliswa kwebhaktheriya, i-oxidation elula nokubukeka akubusheleli, ukusebenza kwesistimu ye-vacuum ngeke kuvele kulesi simo, i-vacuum (0.095MPa) ngaphansi kwesimo emulsification esheshayo ehlakazekile ngokulinganayo, hhayi kumabhamuza enqubo yokukhiqiza, ngakho-ke ingaqinisekisa ukuthi ithambile futhi izinzile.
