Ultrasonic disperseryog mus ncaj qha tso cov particle ncua kev kawm ntawv yuav tsum tau kho nyob rau hauv lub ultrasonic teb thiab "irradiate" nws nrog high-power ultrasonic, uas yog ib tug heev intensive dispersion txoj kev.Ua ntej tshaj plaws, kev nthuav tawm ntawm ultrasonic yoj yuav tsum tau siv 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.Qhov nruab nrab yog nyem thiab rub nyob rau hauv qhov zoo thiab tsis zoo siab ntawm colloid.

Thaum ultrasonic yoj ua rau cov kua nruab nrab, qhov kev ncua deb ntawm nruab nrab molecules nyob rau hauv qhov tsis zoo siab cheeb tsam yuav tshaj qhov tseem ceeb molecular deb uas cov kua nruab nrab tseem tsis hloov, thiab cov kua nruab nrab yuav tawg, tsim microbubbles, uas yuav loj hlob mus rau hauv cavitation npuas.Cov npuas tuaj yeem yaj hauv cov roj ntxiv, lossis lawv tuaj yeem ntab thiab ploj mus, lossis lawv tuaj yeem tawg mus deb ntawm cov theem resonance ntawm ultrasonic teb.Qhov tshwm sim, vau los yog ploj ntawm cavitation npuas hauv cov kua nruab nrab.Cavitation yuav tsim qhov kub thiab txias hauv zos, thiab tsim kom muaj kev cuam tshuam loj heev thiab lub dav hlau micro.Nyob rau hauv qhov kev txiav txim ntawm cavitation, qhov saum npoo ntawm nano hmoov yuav tsis muaj zog, thiaj li kom paub qhov dispersion ntawm nano hmoov.

Nov yog cov kev ceev faj rau kev siv ultrasonic disperser:

1. Tsis pub ua haujlwm tsis muaj kev thauj khoom.

2. Cov dej tob ntawm lub horn (ultrasonic sojntsuam) yog hais txog 1.5cm, thiab cov kua theem zoo dua 30mm.Kev sojntsuam yuav tsum nyob nruab nrab thiab tsis txhob lo rau ntawm phab ntsa.Ultrasonic yoj yog ib tug ntsug longitudinal yoj.Nws tsis yog ib qho yooj yim los tsim convection thaum nws tso rau hauv qhov tob heev, uas cuam tshuam rau kev ua haujlwm ntawm crushing.

3. Ultrasonic parameter teeb tsa: teeb tsa kev ua haujlwm ntawm qhov ntsuas.Rau cov qauv (xws li cov kab mob) uas xav tau qhov kub thiab txias, cov dej khov da dej feem ntau yog siv sab nraud.Qhov tseeb kub yuav tsum qis dua 25 degrees, thiab protein nucleic acid yuav tsis denature.

4. Kev xaiv lub thawv: xaiv ntau lub beakers raws li muaj cov qauv, uas kuj yog qhov tsim nyog rau lub convection ntawm cov qauv hauv ultrasound thiab txhim kho cov crushing efficiency.Piv txwv li;Ib qho 20mL beaker zoo dua li 20mL beaker.Piv txwv li, qhov teeb meem ntawm 100ml coliform qauv: ultrasonic 5 vib nas this / ncua 5 vib nas this rau 70 zaug (tag nrho lub sij hawm yog 10 feeb).Lub zog yog 300W (rau kev siv nkaus xwb), txog 500ML, thiab txog 500W-800W.
