Description

Technical Field

[0001] The utility model relates to the field of nano material processing equipment, in particular to a nano material dispersing device. Background Art

[0002] Nanomaterials refer to materials with at least one dimension in the nanometer scale (1-100nm) in the three-dimensional space. They are a new generation of materials composed of nanoparticles with sizes between atoms, molecules and macroscopic systems. Among them, carbon nanotubes are a one-dimensional quantum material with a special structure. Its radial size is nanometer-scale. It has a unique structure and excellent mechanical, electrical and chemical properties, showing broad application prospects.

[0003] At present, the preparation method of carbon nanotubes has been improved day by day, but due to the small particle size and high surface activity of nanoparticles, they are easy to agglomerate and form larger agglomerates, which seriously hinders the application of carbon nanotubes. At present, the industry mostly uses shearing, ball milling, sand milling, stirring and ultrasonic methods to disperse and grind carbon nanotubes. Shearing dispersion uses shear force to break up large carbon nanotube agglomerates, but while dispersing carbon nanotubes, it will damage the length of carbon nanotubes; grinding methods such as sand milling and ball milling can break up large carbon nanotube agglomerates, but the effect of the "nano effect" of nanomaterials that will closely bond the dispersed small-sized nanomaterials together is relatively small; and ultrasonic dispersion can better avoid the above-mentioned adhesion phenomenon between small-sized nanomaterials in the dispersion, but the effect on larger carbon nanotube agglomerates is relatively weak; it can be seen that the above three dispersion methods have their own advantages and disadvantages. In order to achieve a better dispersion effect, they should be combined and applied.

[0004] At present, the nanomaterial dispersion equipment in the industry mainly includes grinders, ultrasonic dispersers and shear dispersers, and their forces are relatively single. On the other hand, in the prior art, shear dispersers, grinders and ultrasonic dispersers are simply superimposed in series, and the dispersion equipment with multiple dispersion effects cannot form a flexible combination of different dispersion processes and adjustment of the dispersion sequence, thereby restricting the synergy between the dispersion processes.
