Ultrasonic dispersion of alumina

The refinement and dispersion of alumina materials improve their quality

Under the action of ultrasound, the relative size of the composite dispersion decreases, the distribution becomes more uniform, the interaction between the matrix and dispersion is enhanced, and the compatibility is increased.

For some materials, the extrusion pressure decreases after adding ultrasound, and the foam density increases with the increase of ultrasound amplitude. At the same time, the bubbles become smaller, and the size and distribution of bubbles are more uniform. This indicates that ultrasound can promote foam nucleation and bubble growth.

Ultrasonic dispersion of biodiesel

The high-power ultrasonic biodiesel treatment system greatly improves production efficiency

The key to the preparation of biodiesel is the catalytic ester exchange reaction between fatty acid glycerides and low-carbon alcohols such as methanol. Ultrasonic waves have a significant strengthening effect on ester exchange reactions, especially for heterogeneous reaction systems, which can significantly enhance their mixing (emulsification) effect and promote molecular indirect contact reactions. This allows reactions that originally required high temperature (high pressure) conditions to be completed at room temperature (or near room temperature) and shortens reaction time. Ultrasonic waves are not only used in ester exchange reactions, but also in the separation process of reaction mixtures.

According to the user's experimental results, adding ultrasound during the reaction process increased the reaction rate by 20% to 60%,

The esterification reaction temperature is reduced by 30% to 60%, and the amount of methanol used is reduced by 5% to 30%

Reduce the amount of catalyst such as KOH by 20% to 50%, and reduce the overall production cost by 15% to 50%

Meanwhile, due to the reduced amount of methanol used, the separation time of glycerol is also faster.

Ultrasonic graphene dispersion

The preparation of graphene by ultrasonic method is one of the methods to achieve low-cost, large-scale manufacturing and wide commercial applications of graphene.

The application of ultrasonic equipment is mainly in solvent thermal intercalation and oxidation-reduction methods, which are relatively easy to operate and have lower costs than other preparation methods. They are currently the main production methods used for large-scale preparation of nanoscale graphene powder in China. Due to the cavitation effect of ultrasound in liquids, physical phenomena such as microjets and vibrations are formed. At the microscopic level, it plays a role in high-speed stirring, crushing, separation, and dispersion of suspended particles in liquids. Simply put, ultrasound can accelerate and catalyze the reaction in the solution for preparing graphene.

In the solvent thermal intercalation method, graphite powder and intercalation agent are uniformly mixed in an organic solvent in a certain proportion, and then peeled off for a certain period of time using an ultrasonic water bath. After centrifugation and filtration through a microporous membrane, graphene material can be obtained.

The method of oxidation-reduction involves adding graphene oxide powder to deionized water and obtaining a graphene oxide dispersion in deionized water through ultrasonic oscillation. The dispersion is then reduced by adding caffeic acid powder

After the reaction, a graphene solution is obtained, which is also collected by filtration through a microporous membrane and vacuum dried to obtain graphene.
