I-Ultrasonic ibe yindawo yophando kwihlabathi ngenxa yokuveliswa kwayo ekudlulisweni kobuninzi, ukuhanjiswa kobushushu kunye nokusabela kweekhemikhali.Ngophuhliso kunye nokuthandwa kwezixhobo zamandla e-ultrasonic, kuye kwenziwa inkqubela phambili kwi-industrialization eYurophu naseMelika.Ukuphuhliswa kwesayensi kunye neteknoloji e-China iye yaba yinto entsha ye-sonochemistry.Uphuhliso lwayo luye lwaphenjelelwa ngumsebenzi omkhulu owenziwe kwithiyori kunye nokusetyenziswa.
Into ebizwa ngokuba yi-ultrasonic wave ibhekisa kwi-acoustic wave ene-frequency range ye-20k-10mhz.Amandla ayo okusebenza kwintsimi yeekhemikhali ikakhulu ivela kwi-ultrasonic cavitation.Ngomothuko olomeleleyo wamaza kunye ne-microjet enesantya esingaphezulu kwe-100m / s, ukucheba okuphezulu kwe-gradient yamaza othusayo kunye ne-microjet inokuvelisa i-hydroxyl radicals kwisisombululo samanzi.Iziphumo ezihambelanayo zomzimba kunye neekhemikhali ziziphumo zomatshini (ukutshatyalaliswa kwe-acoustic, i-wave shock, i-microjet, njl.), imiphumo ye-thermal (ubushushu obuphezulu bendawo kunye noxinzelelo oluphezulu, ukunyuka kweqondo lokushisa ngokubanzi), iziphumo ze-optical (sonoluminescence) kunye nemiphumo yokuvula (i-hydroxyl radicals are. yenziwe ngesisombululo esimanzi).Iziphumo ezine azikho zodwa, Endaweni yoko, ziyasebenzisana kwaye zikhuthazane ukukhawulezisa inkqubo yokusabela.
Okwangoku, uphando lwesicelo se-ultrasound lubonakalise ukuba i-ultrasound inokusebenzisa iiseli zebhayoloji kwaye ikhuthaze imetabolism.I-ultrasound ye-low intensity ayiyi konakalisa isakhiwo esipheleleyo seseli, kodwa inokunyusa umsebenzi we-metabolic weseli, ikhulise ukunyanzeliswa kunye nokukhetha kwe-membrane yeseli, kwaye ikhuthaze umsebenzi we-biological catalytic we-enzyme.I-high-intensity ultrasonic wave ingenza i-enzyme, yenza i-colloid kwiseli iqhube i-flocculation kunye ne-sedimentation emva kwe-oscillation enamandla, kwaye i-liquefy okanye i-emulsify i-gel, ngaloo ndlela yenza ibhaktheriya ilahlekelwe ngumsebenzi we-biological.Ukwengeza.Ukushisa okuphakamileyo ngokukhawuleza, ukuguquka kweqondo lokushisa, uxinzelelo oluphezulu ngokukhawuleza kunye nokutshintsha koxinzelelo olubangelwa yi-ultrasonic cavitation iya kubulala ezinye iibhaktheriya kwi-liquid, ingasebenzi intsholongwane, kwaye itshabalalise udonga lweeseli zezinye izinto ezincinci ze-emblem.Ukuqina okuphezulu kwe-ultrasound kunokutshabalalisa udonga lweseli kunye nokukhulula izinto kwiseli.Ezi ziphumo zebhayoloji nazo zisebenza kwimpembelelo ye-ultrasound ekujoliswe kuyo.Ngenxa yobungcali besakhiwo sealgal cell.Kukho kwakhona indlela ekhethekileyo yokunyanzeliswa kwe-ultrasonic algae kunye nokususwa, oko kukuthi, isikhwama somoya kwiseli ye-algal isetyenziselwa njenge-nucleus ye-cavitation ye-bubble cavitation, kwaye isikhwama somoya siphukile xa i-bubble cavitation iphukile, okubangelwa iseli yealgal ukulahlekelwa ukukwazi ukulawula ukudada.
