Cov khoom siv ultrasonic emulsification
Raws li qhov kev txiav txim ntawm lub zog ultrasonic, ob lossis ntau dua kua tsis paub tab tau sib xyaw ua ke, ib qho yog cov dej tsis sib xws hauv lwm cov kua los tsim cov kua emulsion. Qhov txheej txheem kev kho no yog hu ua ultrasonic emulsification.
Txhua hom kev nruab nrab thiab cov neeg siv khoom lag luam, xws li tshuaj pleev ib ce thiab khoom tu tawv nqaij, tshuaj pleev tshuaj, xim pleev xim, roj av thiab roj, yog txhua yam lossis ib feem ntawm emulsions. Emulsions muaj nyob rau txhua qhov ntawm lub neej. Kev paub tswj hwm thiab ua kom zoo tshaj plaws yog qhov tseem ceeb los tsim cov khoom lag luam zoo. Qhov tsis zoo txhais tau tias tsim nyog rau daim ntawv thov kawg.
Cov kev lag luam sib txawv muaj qhov sib txawv loj hauv cov txheej txheem tsim tawm ntawm emulsions. Cov kev sib txawv no suav nrog cov khoom siv coj los siv (sib tov, suav nrog ntau yam hauv kev daws teeb meem), cov txheej txheem emulsification, thiab ntau yam kev ua haujlwm Emulsion yog kev sib cais ntawm ob lossis ntau dua kua sau ua kua. High-siv ultrasound yog muab rau cov khoom tawg ua theem (dispersed theem) hauv qhov mob me me ntawm lwm theem ob (kev ua ntu zus). lub zog.
Ob lub cawv tuaj yeem ua ntau hom emulsions, piv txwv li, roj thiab dej. Ua ntej, roj-hauv-dej emulsions, qhov twg cov roj yog cov theem dispersed thiab dej yog qhov nruab nrab dispersion. Thib ob, lawv tuaj yeem tsim dej-hauv-roj emulsions, qhov twg dej yog cov theem dispersed thiab roj yog cov theem txuas ntxiv. Nws kuj ua tau rau ntau lub emulsions, suav nrog" dej-hauv-roj-hauv-dej" emulsions thiab" roj-hauv-dej-hauv-roj" emulsions.
