摘　　要：二氧化硅微球颗粒在无水和水相介质中都极易发生自组装现象,进而严重影响该颗粒的特性研究。为了更好地使用和研究二氧化硅微球颗粒,需要进行解团聚工艺研究。实验研究了不同尺度的颗粒的团聚特性和现象,提出了一种工艺,该工艺方法可以很好地实现大团聚的二氧化硅微球颗粒的解团聚。经过尼康显微镜观察,显示该工艺不仅很好地完成了二氧化硅微球的解团聚,而且提高了颗粒的分散性和稳定性。Silica microspheres in the anhydrous and aqueous media are prone to sel-assembly, which would seriously affect the properties of the particle research. In order to study the use of silica microspheres and particles, the research on the de aggregation of silica microspheres needs to be carried out. We propose a method which is able to achieve the reunion of silica microspheres and particles. We experimentally study the characteristics of different scales reunion particles and phenomena. By using a Nikon microscope, it shows that silica microspheres de-aggregation can be well done, and the dispersion and stability of the particles can be improved.
