Ultrasonic Nanomaterial Dispersion Machine

Nanomaterials, metal oxides, nanoclays or carbon nanotubes tend to be agglomerated when mixed into a liquid. Effective means of dispersing are needed to overcome the bonding forces after dispersing the powder. The ultrasonic breakup of the agglomerate structures in aqueous and non-aqueous suspensions allows utilizing the full potential of nanosize materials. Investigations at various dispersions of nanoparticulate agglomerates with a variable solid content have demonstrated the considerable advantage of ultrasound when compared with other technologies, such as rotor stator mixers, piston homogenizers, or wet milling methods or colloid mills.

ZYSONIC ultrasonic nano dispersion equipment can be run at fairly high solids concentrations. For example for silica the breakage rate was found to be independent of the solid concentration up to 50% by weight. Ultrasound can be applied for the dispersing of high concentration master-batches – processing low and high viscosity liquids. This makes ultrasound good processing solution for paints and coatings, based on different media, such as water, resin or oil.
