Siab Ultrasonic Sono Tshuaj Versus Ultrasonic Nqus Tsev Vacuum

Soj ntsuam Sonicators muaj ntau zaus ntau haib thiab zoo tshaj ultrasonic nqus tsev dej ntxuav. Lub tsev ntxhua khaub ncaws yuav tsum siv sij hawm ua hauj lwm kom tiav qhov kev sojntsuam Sonicator ua tau rau feeb. Thov saib tshooj cai nram no:

Dispersions hauv vitals (a) tau coagulated CNTs hauv lub cev thiab hauv qab los ntawm kev siv da dej sonication rau 8 xuab moos, (b) tshwm dawb-homogenous nrog sonication soj ntsuam 3 feeb, thiab (c) tsis pub dawb-hom txawm tias tom qab 4 lub hlis ntawm zaum hauv chav tsev kub. Qhov concentration ntawm MWCNTs yog 2500 mg / L thiab MWCNTs / SDS ration yog 1:10. (d) MWCNTs ntawm (c) tau muab txo rau 25 mg / L nrog deionized dej.

Nws yog qhov tseeb hais tias MWCNTs tsis tuaj yeem txuam rau hauv dej los ntawm kev siv da dej Sonicator rau 8 xuab moos; muaj ntau cov phom sij ntawm MWCNTs nyob hauv qab ntawm ib lub raj mis me me (Fig. a). Raws li kev khiav hauj lwm 20 kHz uas tau thov los ntawm ib qho kev sojntsuam Sonicator, cov MWCNTs yog cov neeg ua haujlwm thoob plaws hauv lub cev, ua ib hom tshuaj dawb tsis sib haum (daim duab b). Tshaj tawm, tsis muaj kev txo qoob raug cai txawm tom qab plaub lub hlis ntawm zaum ntawm qhov chaw sov (Daim duab c.).
