Nanoparticles muaj me me particle loj, siab saum npoo zog thiab nyiam spontaneous agglomeration.Lub hav zoov ntawm agglomeration yuav cuam tshuam rau qhov zoo ntawm nano hmoov.Yog li ntawd, yuav ua li cas los txhim kho cov dispersion thiab stability ntawm nano hmoov nyob rau hauv kua nruab nrab yog ib tug tseem ceeb heev cov ntsiab lus ntawm kev tshawb fawb.

Particle dispersion yog ib qho kev qhuab qhia tshiab nyob rau pem hauv ntej tsim nyob rau hauv xyoo tas los no.Lub npe hu ua particle dispersion yog hais txog qhov project uas cov hmoov nplej tau sib cais thiab dispersed nyob rau hauv cov kua nruab nrab thiab uniformly faib nyob rau hauv tag nrho cov kua theem, feem ntau suav nrog peb theem: wetting, disaggregation thiab stabilization ntawm dispersed hais.Kev ntub dej yog hais txog cov txheej txheem maj mam ntxiv cov hmoov rau hauv cov eddy tam sim no tsim nyob rau hauv qhov sib tov, kom cov huab cua los yog lwm yam impurities adsorbed rau saum npoo ntawm cov hmoov yog hloov los ntawm cov kua.Disaggregation yog hais txog kev sib sau ua ke nrog qhov loj me me disperse mus rau hauv cov khoom me me los ntawm kev siv tshuab los yog super tiam.Stabilization txhais tau hais tias kom ntseeg tau tias cov hmoov hmoov tuaj yeem sib cais hauv cov kua rau lub sijhawm ntev.Raws li kev sib txawv dispersion, nws tuaj yeem muab faib ua lub cev dispersion thiab tshuaj dispersion.Ultrasonic dispersion yog ib qho ntawm lub cev dispersion txoj kev.

Ultrasonic dispersiontxoj kev: ultrasonic muaj cov yam ntxwv ntawm yoj ntev, kwv yees ncaj kab propagation, yooj yim zog concentration, thiab lwm yam. Ultrasound tuaj yeem txhim kho cov tshuaj tiv thaiv tus nqi, txo lub sij hawm cov tshuaj tiv thaiv thiab txhim kho cov kev xaiv ntawm cov tshuaj tiv thaiv;Nws tseem tuaj yeem ua rau muaj tshuaj lom neeg tsis tuaj yeem tshwm sim thaum tsis muaj ultrasound.Ultrasonic dispersion yog ncaj qha tso cov khoom tshem tawm kom raug kho hauv thaj chaw loj hlob thiab kho lawv nrog ultrasonic nthwv dej ntawm qhov tsim nyog zaus thiab lub zog, uas yog txoj kev siv zog ntau heev.Tam sim no, lub tshuab ntawm ultrasonic dispersion feem ntau ntseeg tias muaj feem xyuam rau cavitation.Kev nthuav tawm ntawm ultrasonic nthwv dej yog nqa los ntawm qhov nruab nrab, thiab muaj lub sijhawm hloov pauv ntawm qhov zoo thiab tsis zoo siab hauv cov txheej txheem nthuav tawm ntawm ultrasonic yoj hauv nruab nrab.Qhov nruab nrab yog nyem thiab rub nyob rau hauv alternating zoo thiab tsis zoo pressures.Thaum lub ultrasonic nthwv dej nrog txaus amplitude ua rau qhov tseem ceeb molecular deb ntawm cov kua nruab nrab kom tas li, cov kua nruab nrab yuav tawg thiab tsim microbubbles, uas yuav ntxiv mus rau hauv cavitation npuas.Ntawm ib sab, cov npuas no tuaj yeem yaj hauv cov kua nruab nrab, thiab tseem tuaj yeem ntab thiab ploj;Nws kuj tseem tuaj yeem tawg mus deb ntawm qhov resonance theem ntawm ultrasonic teb.Kev xyaum tau ua pov thawj tias muaj qhov tsim nyog supergeneration zaus rau dispersion ntawm ncua kev kawm ntawv, thiab nws cov nqi nyob ntawm seb qhov luaj li cas ntawm cov khoom tshem tawm.Vim li no, nws yog qhov zoo kom nres rau qee lub sijhawm tom qab yug me nyuam super thiab txuas ntxiv lub hnub yug super kom tsis txhob muaj cua sov.Nws kuj yog ib txoj hauv kev zoo los siv cua lossis dej kom txias thaum lub sijhawm yug super.
