Amandla e-Ultrasonic asebenza endaweni ephakathi, okuzokwenza ukuthi izinhlayiya zidlidlize ngesivinini esikhulu futhi zikhiqize izinguquko zemishini ezifana nesivinini, ukusheshisa, ukucindezela komsindo, nokuqina komsindo, ngaleyo ndlela kubangele imiphumela yemishini. I-Ultrasound iwuhlobo lokusabalalisa amandla emishini, ehlobene nenqubo yegagasi futhi izokhiqiza umphumela oqondile wokudlidliza. Lapho i-wave ye-ultrasonic isakazeka phakathi nendawo, nakuba i-amplitude ye-particle displacement incane, ukusheshisa kwe-particle okubangelwa i-ultrasonic wave kukhulu kakhulu.
Uma i-20kHz, i-1W/cm2 ultrasonic wave isakazeka emanzini, i-amplitude yengcindezi yomsindo ekhiqizwa yiyo ingu-173kPa, okusho ukuthi i-amplitude yomsindo kufanele ishintshe izikhathi ezingu-20,000 phakathi kokuhle nokubi okungu-173kPa ngomzuzwana, kanye nokusheshisa okuphezulu kwezinhlayiyana Kufike ku-14400 okuyi-acceleration eyi-1250km/i-acceleration eyi-1250km/ amandla adonsela phansi, ukunyakaza okunamandla nokushintsha ngokushesha kwemishini kuwumphumela wokudlidliza wemishini wamandla e-ultrasound.
Lapho i-ultrasonic medium ingeyona i-uniform layered medium (njengezicubu zebhayoloji, umzimba womuntu, njll.), i-acoustic impedance yongqimba ngalunye lwemidiya izobangela amaza omsindo abonisiwe ukuthi abonise futhi akhe igagasi elimile. Ama-antinode nama-node egagasi elimile adala ingcindezi nokushuba kanye nezinguquko zokusheshisa. Njengoba inqwaba yezinhlayiya zemidiya ehlukene (njengama-biomolecules) ihlukile, isivinini sokudlidliza esibangelwa ukushintsha kwengcindezi sihlukile, futhi ukuguqulwa kwengcindezi okubangelwa ukunyakaza okuhlobene phakathi kwezinhlayiya zemidiya kungesinye isizathu somphumela we-ultrasonic mechanical. Imiphumela yemishini esebenzisa i-ultrasound kufanele icutshungulwe (i-perforation, ukusika, ukuhlanganisa, ukuqinisa ubuso, ukushisela, ukuhlanza, ukupholisha, nokususwa kwamafilimu angathandeki nokungcola, njll.), futhi iphinde isetshenziselwe ukusheshisa ukuhlakazeka, i-homogenization, i-emulsification, nokuchoboza , Ukuvala inzalo nezinye izinqubo.
Umphumela wemishini we-ultrasound usetshenziswe kabanzi ekukhiqizeni, futhi izibonelo zimi kanje.
Ukuyaluza komshini
Ukudlidliza kwe-Ultrasonic high-frequency kanye nomfutho wemisebe kungenza ukuyaluza okusebenzayo futhi kugeleze kugesi noketshezi. Ijethi eliqinile nokugeleza kwe-micro-rush yendawo okukhiqizwe ukudlidliza kwebhamuza le-cavitation endaweni eqinile kungenza buthaka ngokuphawulekayo ukungezwani kwendawo nokungqubuzana koketshezi, futhi kucekele phansi ungqimba olunamathiselwe lwesixhumi esibonakalayo esiwuketshezi oluqinile, ngakho-ke alukwazi ukufinyelela ekuyaluza okujwayelekile kwe-low-frequency mechanical. umphumela. Lo mphumela uyisisekelo esingokomzimba sokusetshenziswa kwezidakamizwa ngesikhumba somuntu, imikhiqizo yobuhle esikhumbeni somuntu, i-ultrasonic degassing, izinga lokudla kanye nezimonyo kanye nokucwengwa.
Ukuxubana
Ukucindezela kanye nomphumela wokushisa ophezulu wokudlidliza kwe-ultrasonic kanye ne-cavitation kusetshenziselwa ukukhuthaza ukungena okuhlangene kwama-molecule phakathi koketshezi olubili, okuqinile okubili, noma ukuxhumana kwe-liquid-solid kanye ne-liquid-gas ukwakha izakhiwo zezinto ezibonakalayo. I-Ultrasonic welding yezinsimbi noma amapulasitiki, i-emulsification ye-ultrasonic, ukuhlanza, i-atomization ingahlukaniswa njengemiphumela enjalo.
I-Homogenize
Ngemuva kokuthi ama-bubbles e-cavitation evaliwe, i-wave shock wave ingachoboza izinhlayiya oketshezini ukuze zenze kahle; yenza umfaniswano we-crystal; hlakaza amaconsi obisi amakhulu nangalingani enze izinto ezincane ezifanayo (njengama-ejenti ahlukile wezokwelapha, ama-ejenti okwelapha umdlavuza, njll.); Kungafaka ngisho ne-thrombolysis neminye imiphumela.
Ukubumbana
Ukudlidliza kwe-Ultrasonic kungenza izinhlayiya ezimisiwe kugesi kanye ne-liquid medium zihambe ngesivinini esihlukile, okwandisa ithuba lokushayisana kwesigaba; noma ukusebenzisa amagagasi amile ukuze abenze bathambekele kuma-antinode, ngaleyo ndlela inqubo ye-agglomeration iyenzeka. Ukuqoqwa kothuli kuflue nemvula yokwenziwa kuwela kulesi sigaba.
Isenzo sokusika imishini
Ngenxa yokusheshisa okukhulu kokudlidliza kwe-ultrasonic kanye nomphumela we-cavitation kanye nokugqwala kwe-acoustic, ukucubungula okukhethekile nokunembayo kwezinto eziqinile neziqinile (amagugu, i-ceramics, ingilazi, insimbi kazibuthe, njll.) kungenziwa.
Smash
Ukusetshenziswa kwe-high-intensity ultrasound pulses kungachoboza amatshe ezinso namatshe enyongo emzimbeni ngaphandle kokulimaza izicubu ezithambile.
