Ultrasonic yojyog ib hom elastic mechanical yoj hauv cov khoom nruab nrab. Nws yog ib hom yoj daim ntawv, yog li nws tuaj yeem siv los txheeb xyuas cov ntaub ntawv physiological thiab pathological ntawm tib neeg lub cev. Nyob rau tib lub sijhawm, nws kuj yog ib hom ntawm lub zog. Thaum ib qho koob tshuaj ntawm ultrasound kis tau nyob rau hauv lub cev, los ntawm lawv cov kev sib cuam tshuam, nws tuaj yeem ua rau muaj kev hloov pauv hauv kev ua haujlwm thiab cov qauv ntawm lub cev, uas yog, cov nyhuv ultrasound. Cov teebmeem tseem ceeb ntawm ultrasound ntawm cov hlwb yog thermal nyhuv, cavitation nyhuv thiab txhua yam nyhuv.

Ultrasonic dispersing tshuabyog ib hom dispersing txoj kev nrog lub zog siab, uas ncaj qha tso cov particle ncua kev kawm ntawv yuav tsum tau kho nyob rau hauv lub ultrasonic teb thiab "irradiates" nws nrog siab zog ultrasonic. Ua ntej tshaj plaws, kev nthuav tawm ntawm ultrasonic yoj xav tau qhov nruab nrab raws li tus neeg nqa khoom. Kev nthuav tawm ntawm ultrasonic yoj hauv nruab nrab muaj lub sijhawm hloov pauv ntawm qhov zoo thiab qhov tsis zoo, thiab qhov nruab nrab yog nyem thiab rub nyob rau hauv qhov zoo thiab tsis zoo siab ntawm colloid. Thaum lub ultrasonic nthwv dej ua rau cov kua nruab nrab, qhov kev ncua deb ntawm cov nruab nrab molecules nyob rau hauv qhov tsis zoo siab cheeb tsam yuav tshaj qhov tseem ceeb molecular deb ntawm cov kua nruab nrab, thiab cov kua nruab nrab yuav tawg thiab tsim ib cov kua Microbubbles loj hlob mus rau hauv cavitation npuas. Cov npuas tuaj yeem yaj dua hauv cov roj, ntab thiab ploj, lossis tawg tawm ntawm theem resonance ntawm ultrasonic teb. Nws yog qhov tshwm sim uas cavitation npuas yog tsim, tawg lossis ploj hauv cov kua nruab nrab. Cavitation yuav tsim qhov kub thiab txias hauv zos, thiab ua rau muaj kev cuam tshuam loj heev thiab lub dav hlau micro. Nyob rau hauv qhov kev txiav txim ntawm cavitation, lub zog nto ntawm nano hmoov yog tsis muaj zog, thiaj li kom paub qhov dispersion ntawm nano hmoov.

Tus tsim ntawm lub taub hau dispersing ntawm lub ultrasonic disperser tuaj yeem ua tau raws li qhov xav tau ntawm qhov sib txawv viscosity thiab particle loj. Qhov sib txawv ntawm qhov tsim ntawm on-line stator thiab rotor (emulsifying lub taub hau) thiab lub taub hau ua hauj lwm ntawm batch tshuab yog feem ntau yog vim li cas rau kev thauj mus los. Nws yuav tsum tau muab sau tseg tias qhov sib txawv ntawm ntxhib precision, nruab nrab precision, zoo precision thiab lwm yam kev ua hauj lwm lub taub hau hom tsis yog tsuas yog cov kev npaj ntawm rotor hniav, tab sis kuj qhov txawv ntawm cov geometric yam ntxwv ntawm txawv ua hauj lwm lub taub hau yog tib yam. Qhov tooj, qhov dav thiab lwm yam geometric nta tuaj yeem hloov pauv cov haujlwm sib txawv ntawm stator thiab rotor ua haujlwm lub taub hau.

Lub hauv paus ntsiab lus ntawmultrasonic dispersertsis yog mysterious thiab nyuaj. Nyob rau hauv luv luv, lub zog hluav taws xob hloov mus rau hauv suab zog los ntawm transducer. Lub zog no hloov mus ua npuas me me los ntawm cov kua nruab nrab. Cov npuas me no tawg sai sai, yog li ua lub luag haujlwm ntawm crushing hlwb thiab lwm yam khoom.
