摘要

Abstract

A kind of experimental setup

named as UC-1500

was designed. SiO2 nanoparticles preparing by ultrasonic-mechanical method were studied

and the effects of ultrasound field

dispersant concentration and grinding time on grain-size and appearance of SiO2 nanoparticles were investigated. The results showed that the grain-size was smaller and the stability of SiO2 nanoparticles was better in ultrasonic field.The optimum values of such reaction factors as the space between two adjacent teeth of stirring rad

grinding time

dispersant concentration and the rotating speed of stirring rod were 15 mm

9 h

0.09 g8226;L-1 and 300 r8226;min-1

respectively.With grinding time being the main factor

the effects of dispersant concentration

the rotating speed of stirring rod and the space between two adjacent teeth of stirring rod decreased successively.
