I-Nanoparticles inobungakanani be-particle encinci, amandla aphezulu aphezulu kunye nokuthambekela kwe-agglomeration ezenzekelayo.Ubukho be-agglomeration buya kuchaphazela kakhulu inzuzo ye-nano powders.Ngoko ke, indlela yokuphucula ukusabalalisa kunye nokuzinza kwe-nano powders kwi-liquid medium sisihloko sophando esibaluleke kakhulu.

I-Paticle dispersion luqeqesho olutsha lomda oluphuhliswe kwiminyaka yakutshanje.Okubizwa ngokuba yi-particle dispersion ibhekisela kwiprojekthi apho amaqhekeza e-powder ahlulwe kwaye ahlakazwe kwindawo yolwelo kwaye asasazwe ngokufanayo kwisigaba esipheleleyo solwelo, ngokukodwa kubandakanywa izigaba ezintathu: ukumanzisa, ukuchithwa kunye nokuzinzisa amaqhekeza ahlakaziweyo.Ukumanzisa kubhekisa kwinkqubo yokongeza ngokucothayo umgubo kwi-eddy yangoku eyenziwe kwinkqubo yokuxuba, ukuze umoya okanye ezinye izinto ezimdaka ezibhengezwe kumphezulu womgubo zithathelwe indawo ngolwelo.Ukwahlula-hlula kubhekiselele ekwenzeni iiaggregates ezinobungakanani bamasuntswana amakhulu asasazeke abe ngamasuntswana amancinane ngoomatshini okanye ngeendlela zokuzala okuphezulu.Ukuzinzisa kuthetha ukuqinisekisa ukuba i-powder particles inokusasazwa ngokufanayo kwi-liquid ixesha elide.Ngokweendlela ezahlukeneyo zokusasazeka, inokwahlulwa ibe yintlupheko yomzimba kunye nokusasazwa kweekhemikhali.Ukusasazwa kwe-Ultrasonic yenye yeendlela zokusasazeka ngokomzimba.

Ukusasazwa kwe-ultrasonicindlela: I-ultrasonic ineempawu zobude be-wave, malunga nokusabalalisa umgca ochanekileyo, ukugxilwa kwamandla okulula, njl.Kwakhona kunokuvuselela ukuphendulwa kweekhemikhali ezingenakukwenzeka ngokungabikho kwe-ultrasound.I-Ultrasonic dispersion kukubeka ngokuthe ngqo iinqununu ezimisiweyo ukuba ziphathwe kwintsimi yokukhula okuphezulu kwaye zibaphathe ngamaza e-ultrasonic amatyeli afanelekileyo kunye namandla, okuyindlela yokusabalalisa kakhulu.Okwangoku, indlela yokusasazwa kwe-ultrasonic ngokuqhelekileyo ikholelwa ukuba inxulumene ne-cavitation.Ukusasazwa kwe-wave ye-ultrasonic iqhutywe yi-medium, kwaye kukho ixesha elitshintshileyo loxinzelelo oluhle kunye nolubi kwinkqubo yokusabalalisa i-ultrasonic wave phakathi.Uphakathi uyacudiswa kwaye utsalwe phantsi koxinzelelo olulungileyo kunye nolubi olutshintshanayo.Xa i-wave ye-ultrasonic ene-amplitude eyaneleyo isebenza kumgama obalulekileyo we-molecular medium ye-liquid ukuze igcine isigxina, i-medium medium iya kuphuka kwaye yenze i-microbubbles, eya kukhula ngakumbi ibe yi-cavitation bubbles.Kwelinye icala, la maqamza anokuphinda anyibilike kulwelo oluphakathi, kwaye angadada kwaye anyamalale;Inokuthi iphinde iwele kude nesigaba se-resonance yentsimi ye-ultrasonic.Ukuziqhelanisa kuye kwabonisa ukuba kukho i-frequency ye-supergeneration efanelekileyo yokusabalalisa ukumiswa, kwaye ixabiso layo lixhomekeke kubukhulu beengqungquthela ezimisiweyo.Ngesi sizathu, kulungile ukumisa ixesha elithile emva kokuzalwa okuphezulu kwaye uqhubeke nokuzalwa okuphezulu ukuphepha ukutshisa.Ikwayindlela elungileyo yokusebenzisa umoya okanye amanzi ukupholisa ngexesha lokuzalwa okuphezulu.
