Description:

Dispersion by ultrasound is a consequence of microturbulences caused by fluctuation of pressure and cavitation. Investigations at different materials, such as aqueous solutions of nanoparticulate siliciumdioxid powder and spray frozen agglomerates with a variable solid content have demonstrated the considerable advantage of ultrasound when compared with other technologies, such as rotor-stator mixers (e.g. turrax) or colloid mills. In particular for small matter from several nanometers to couple of microns, ultrasonic cavitation is very effective in breaking agglomerates, aggregates and even primaries. When ultrasound is being used for the milling of high concentration batches, the liquid jets streams resulting from ultrasonic cavitation, make the particles collide with each other at velocities of up to 1000km/h. This breaks van der Waals forces in agglomerates and even primary particles. Large particles are subject to surface erosion (via cavitation collapse in the surrounding liquid) or particle size reduction (due to fission through interparticle collision or the collapse of cavitation bubbles formed on the surface).

Ultrasonic liquid processing is described by a number of parameters. Most important are amplitude, pressure, temperature, viscosity, and concentration. The process result, such as particle size, for a given parameter configuration is a function of the energy per processed

volume. The function changes with alterations in individual parameters. Furthermore, the actual power output per surface area of the sonotrode of an ultrasonic unit depends on the parameters.

So we will collect many information before your order. Or we will recommend buy one set for test first, to found the best work parameter and then producing in large scale.

Application:

Typical applications of ultrasonic sonochemistry include ultrasonic homogenization, phacoemulsification, ultrasonic dispersion, depolymerization and wet grinding (particle size reduction), cell disruption and disintegration, extraction, degassing, and sonochemical processes;

Ultrasonic dispersion does not require the use of emulsifiers. In many cases, the diameter of the dispersed particles can reach 1μm or less. It can be carried out between solid, liquid, and gas phases of the same substance, or between different solids, liquids and gases. It has been widely used in food sample detection and analysis, preparation of nanomaterials, etc.

Such like :

● Paint, titanium oxide, iron oxide, carbon, etc. are dispersed in water or solvent.

● Graphene micronization

● Dispersion of fluorescent materials

● Dispersion of photosensitive materials

● Dispersion of dyes in molten paraffin
