Description

technical field [0001] The invention relates to the field of nanomaterial processing devices, in particular to a device for large-scale dispersion of nanomaterials by liquid turbulent instantaneous high-pressure shearing method. Background technique [0002] Due to the special nano-effects of the nano-structural units (including dots, tubes, and strips), nanomaterials have more excellent properties than ordinary materials, and have attracted more and more attention and applications. However, in practical applications, the agglomeration of nanostructure units seriously affects the play of nanoeffects, making it difficult to maintain the excellent properties of nanomaterials in applications. Therefore, the development of effective nanomaterial dispersion technology is one of the key technologies that need to be solved urgently in the practical application of nanomaterials. The existing nanomaterial dispersion technologies mainly include ultrasonic, ball milling and high-spee...

AI Technical Summary

Problems solved by technology

Among them, ultrasound and ball milling have played a certain role in laboratory research. However, in the large-scale application of nanomaterial dispersion, ultrasonic technology has small output energy, uneven distribution of output energy, and ball milling technology also has high energy consumption. Disadvantages, it is difficult to get further application and promotion

Although the high-speed shear dispersion technology can form a certain scale, it has a poor effect on eliminating the hard agglomeration of nanostructure units (bond energy greater than 100 kJ / mol), and at the same time consumes a lot of energy

In addition, the above three dispersion techniques cannot solve the problem of secondary agglomeration of nanostructure units.
