Ngaphansi kwesenzo se-Ultrasonic Fluid Energy, izinhlobo ezimbili noma ezimbili zotshwala ezingahambisani zixutshwe ndawonye, lapho umzimba ocacile uzwela ngendlela efanayo ukwakha i-emulsion uketshezi kolunye uketshezi. Le nqubo yokucubungula ibizwa nge-ultrasonic emulsation.
Imikhiqizo ehlukahlukene ehlukahlukene nemikhiqizo yabathengi, efana nezimonyo nemikhiqizo yokunakekelwa kwesikhumba, imifino yemithi, upende, amafutha okugcoba kanye namafutha. Ama-emulsion akhona kuzo zonke izici zokuphila. Ukwazi ukulawula nokwandisa ukusebenza kubalulekile ukuze ukhiqize ukuphakama - imikhiqizo esezingeni. Ikhwalithi ichazwa njengokufanelekile kwisicelo sokugcina.
Isingeniso se-Emulsation
Izimboni ezahlukahlukene zinezinqubo zokukhiqiza ze-Emulsion ezahlukene kakhulu. Lokhu kwehluka kufaka phakathi izakhi ezisetshenzisiwe (ukuxuba, kufaka phakathi izakhi ezahlukahlukene kusisombululo), izindlela ze-emulsation, kanye nezimo eziningi zokucubungula. I-Emulsion ingukuhlakazeka kweziphuzo ezimbili noma ngaphezulu ezingenakuqhathaniswa. I-High - I-Intensity Ultrasound ihlinzekwa ukusabalalisa isigaba se-liquid (isigaba esihlakazekile) kumaconsi amancane wesigaba sesibili (isigaba esiqhubekayo). amandla.
Ama-ketshezi amabili angakha izinhlobo ezahlukene zama-emulsions, ngokwesibonelo, uwoyela namanzi. Okokuqala, uwoyela - ku - ama-emulsions amanzi, lapho i-oyili isigaba esihlakazekile namanzi kuyindlela yokuhlakazeka. Okwesibili, bangakha amanzi - Ku - ama-emulsion kawoyela, lapho amanzi ahlakazekile kanye namafutha kuyisigaba esiqhubekayo. Kungenzeka futhi wakhe ama-emulsions amaningi, kufaka phakathi "amanzi - kuwoyela - ku-oyela - ku - amanzi" ama-emulsions kanye "namafutha - ku-emulsions.
Inqubo ye-Ultrasonic Cavitation inqubo
I-Phacoemulsification ibangelwa yi-cavitation. I-Ultrasound edlula emzimbeni we-slag ibangela ukucindezela ngokuqhubekayo nokukhula. I-High - I-Intensity Ultrasound inikeza amandla adingekayo ukusabalalisa isigaba soketshezi. Lapho ingcindezi ephezulu ifinyelelwa, uketshezi luqhuma lapho kubuthakathaka khona ubuthakathaka. Ngemuva kokuhlangana okunjalo, kwavela ukweqiwa ngokweqile lapho kwenzeka khona lapho i-agglomeration yatholakala, kwatholakala eminye imithambo. Kulezi zimpahla, igesi elichithekile emzimbeni we-slag liqhuma ngesimo sama-bubble ngemuva kwesikhathi esiqinile.
Ukuze uzinze ulwandle olusanda kulungiswa lwasesitimile ehlakazekile ukuvikela ama-coalescence, ama-emulsifiers (izinto ezisebenzayo, ama-surfactants) futhi abaqinisi bengezwe ku-emulsion. Ukusatshalaliswa kosayizi wokugcina kugcinwa ezingeni elifanayo nalapho amaconsi endaweni yokuhlakazeka ye-ultrasonic ayathuthukiswa futhi asatshalaliswa.
Inqubo ye-Cavitation ithinteke imvamisa nokuqina kwamagagasi e-ultrasonic. Ukuvela kwe-cavitation emzimbeni kuncike ngezinga elikhulu phambi kwegesi elingaxazululiwe ekumisweni koketshezi, okubonakala sengathi kusebenza njenge-catalyst. Ngaphansi kwengcindezi ethile, ukwakheka kwe-cavity kuncike ngezinga elithile esikhathini sokuthuthuka kanye nokuvama kwe-ultrasonic. Inqubo ye-phacoemulhassion imele umncintiswano phakathi kwezinqubo eziphikisayo. Ngakho-ke, kuyadingeka ukuthi ukhethe izimo ezifanele zokusebenza kanye namafrikhwensi ukuze umphumela wokubhubhisa unamandla.
Ukulungiselela uwoyela - Ku - Emulsion Water emulsion, ukuqina komsindo okuphezulu kuphansi kakhulu kunalokho kwamanzi - Kuleli - emulsion. Uhlobo lwensimu yomsindo luthinta inqubo ye-emulsation, okungukuthi, kufakwa igagasi elithile lokuhamba. Uma kuqhathaniswa nokusebenzisa amaza athile asemvalweni, ukusebenza kahle kwenqubo kuyathuthuka. Lokhu kungachazwa ngeqiniso lokuthi ensimini yegagasi le-tuliave, inqubo ehlukile yokuhlakazeka, okungukuthi, ukuvumelanisa kubusa.
