Ultrasonic disperserndeyekuisa zvakananga iyo particle suspension kuti irapwe mumunda we ultrasonic uye "irradiate" iyo ne-high-power ultrasonic, iyo inonyanya kupararira nzira.Chekutanga pane zvese, kupararira kweiyo ultrasonic wave inoda kutora yepakati semutakuri.Iyo kuparadzirwa kweiyo ultrasonic wave mukati mepakati ine inochinjana nguva yeyakanaka uye yakaipa kumanikidza.Iyo yepakati inosvinwa uye inodhonzwa pasi peyakanaka uye isina kunaka kudzvanywa kwecolloid.

Kana ultrasonic wave ichiita pane yepakati mvura, chinhambwe chiri pakati pepakati mamorekuru munzvimbo isina kunaka yekumanikidza inodarika iyo yakakosha molecular kureba iyo yemvura yepakati inoramba isina kuchinjika, uye iyo yemvura yepakati ichatsemuka, ichigadzira microbubbles, iyo inokura kuita cavitation bubbles.Mabhubhu anogona kunyungudutswa mugasi zvakare, kana anogona kuyangarara kumusoro uye kunyangarika, kana anogona kudonha kubva kure resonance chikamu che ultrasonic munda.Chiitiko, kudonha kana kunyangarika kwe cavitation bubbles mune yemvura yepakati.Cavitation inoburitsa tembiricha yemuno uye yakanyanya kudzvanywa, uye inogadzira yakakura simba rekuita uye micro jet.Pasi pechiito che cavitation, pamusoro pe nano powder ichave isina simba, kuitira kuti uone kupararira kwe nano powder.

Heano maitiro ekuchengetedza ekushandiswa kwe ultrasonic disperser:

1. Hapana-kuremerwa kushanda kunobvumirwa.

2. Mvura yakadzika yenyanga (ultrasonic probe) inenge 1.5cm, uye chiyero chemvura chiri nani kupfuura 30mm.Iyo probe inofanira kunge iri pakati uye kwete kunamatira kumadziro.Ultrasonic wave is a vertical longitudinal wave.Hazvisi nyore kuumba convection kana yaiswa yakadzika, iyo inokanganisa kupwanya kushanda.

3. Ultrasonic parameter setting: gadzirisa maitiro ekushanda kwechiridzwa.Kune samples (senge mabhakitiriya) anonzwira tembiricha zvinodiwa, kugeza echando kunowanzoshandiswa kunze.Iyo tembiricha chaiyo inofanira kunge yakaderera pane 25 madhigirii, uye mapuroteni nucleic acid haaite denature.

4. Kusarudzwa kwemudziyo: sarudza mabheji akawanda sezvaaine sampuli, iyo inobatsirawo kune convection yemasampuli mu ultrasound uye inovandudza kuputsika kwekushanda.Semuyenzaniso;Beaker ine 20mL iri nani pane 20mL beaker.Semuenzaniso, marongero ekugadzirisa 100ml coliform sampuli: ultrasonic 5 seconds / interval 5 seconds for 70 times (nguva yakazara maminitsi gumi).Iyo simba i300W (yekureva chete), ingangoita 500ML, uye ingangoita 500W-800W.
