Imininingwane Ejwayelekile mayelana nokucubungula kwe-Ultrasonic

I-Ultrasound iye yavela ebuchwepheni obuphuthumayo, phakathi neminyaka eyishumi edlule futhi isungule ubuchwepheshe bokucubungula ngokugcwele. Ukuthembeka okuphezulu nokukala okuphansi kanye nezindleko zokugcina eziphansi futhi ukusebenza kahle kwamandla yenza i-ultrasound ingxabano ethembisayo yokwakha imishini yokucubungula amanzi. I-Ultrasound inikeza amathuba engeziwe engeziwe: I-Cavitation - umphumela oyisisekelo we-ultrasonic - ivumela imiphumela emisha ezinqubo eziphilayo, zamakhemikhali nezomzimba.

Ngenkathi ukuqina okuphansi noma i-high-frequency ultrasound kusetshenziselwa ukuhlaziywa, ukuhlolwa okungekho okungonakalisayo nokucabanga, i-high-intensity ultrasound isetshenziselwa ukucubungula iziphuzo ezifana Ukuxuba, Emulsifying, Ukuhlakazeka futhi i-deagglomeration, cell nokwahlukana of ukuchithwa kwe-enzyme. Lapho ukuphuza utshwala ngokweqile, amagagasi omsindo asakaze emithonjeni yamanzi ashukumisela ukushintsha ukucindezela okuphezulu (ukucindezela) nokujikeleza okuncane (ukungavamile), namazinga kuye ngokuthi imvamisa. Ngesikhathi umjikelezo ophansi ocindezelayo, amagagasi aphakeme kakhulu e-ultrasonic enza ama-bubbles amancane avulekile noma aphuma emanzini. Lapho ama-bubbles athola umthamo lapho bengakwazi khona ukuwuthola amandla, awela phansi ngesihluku phakathi nomjikelezo ophezulu wokucindezela. Lokhu kwenzeka kuthiwa yi-cavitation. Phakathi nokushisa okuphezulu kakhulu (cishe 5,000K) kanye nezingcindezi (cishe 2,000atm) kufinyelelwe endaweni yangakini. I-implosion ye-bubble cavitation nayo ibangele ama-jets ahlanzekile angama-280m / s velocity.

Ngokuvamile, i-cavitation e-liquids ingabangela i-degassing esheshayo nephelele: qalisa ukuphendula kwamakhemikhali ahlukene ngokudala ama-ioni yamahhala (ama-radicals) mahhala; Ukusheshisa Ukuphendula Kwemvelo ngokugqugquzela ukuxuba kwama-reactants; ukwandisa ukusabela kwe-polymerization nokudonswa kwe-depolymerization okwesikhashana ukusakaza ama-aggregates noma ngokuphula ngokuphelele izibopho zamakhemikhali emaketangeni e-polymeric; ukwandisa emulsification amazinga; ukuthuthukisa izinga lokusakaza; ukhiqiza emulsions okugxile kakhulu noma i-uniform dispersions we-micron-size noma izinto zokwenza izinto ezincane; usize ukukhipha izinto ezinjengama-enzyme ezivela esilwaneni, ezitshalweni, emvubelo, noma emangqamuzaneni ebhaktheriya; susa amagciwane kusuka kumcubu onegciwane; futhi ekugcineni, siphume futhi siphule izinhlayiya ezikhungethekile, kuhlanganise nezinhlobo ezincane.
