The converters corresponding to your INVOICE NO. HS2015021 work very well. We would like to order more

—— Peter

I'm very happy with your good communication skills as well as follow up and good deal. I will definitely inform you my further program for further coo

—— Vinay

We tested it and it worked.  I will let you know about future purchases soon.

—— Alvin

Thank you! It is a pleasure, to work with a company that wants to make it right for the customer :) many times i deal with Chinese companies that do not care about the customer and long term business. I think I made the right decision going with you and Altrasonic !!!

Working principle and application of ultrasonic dispersion equipment



The more common application of power ultrasound in liquids is ultrasonic dispersion. Ultrasonic dispersion equipment can be used to disperse and depolymerize solids into liquids, which is an important application of ultrasonic equipment. The dispersion of ultrasonic waves in liquids is mainly the cavitation effect of liquids based on ultrasonic waves. Ultrasonic cavitation can generate high shear forces, breaking the particle agglomerates into individual dispersed particles.


The violent bubble collapse in the cavitation process causes extreme local temperatures, generates free radicals and causes many chemical (sonochemical) reactions (for example, oxidation of pollutants, sterilization, polymerization, desulfurization, degradation of long-chain molecules, etc.). At the same time, flowing current, extremely fast micro-jets and huge shear force are generated in the cavitation field, which promote a wide range of physical (mechanical) effects (for example, emulsification, particle breakage, cell destruction, homogenization, dispersion, Depolymerization, degassing, etc.).


Ultrasonic dispersion has a wide range of applications in many fields. Such as food, cosmetics, medicine, chemistry, etc.

1. Food industry
The use of lipophilic bioactive ingredients in food and beverage products (for example, oil-soluble vitamins, coenzymes, phytosterols, carotenoids, flavonoids, curcumin, phenols, polyunsaturated lipids, etc.) has always been technically problem. Since these compounds are insoluble in water, they cannot be incorporated into water-based beverages by simple soaking, so these materials exhibit very low bioavailability.
These challenges can be overcome by formulating lipophilic bioactive ingredients into water-compatible nanoemulsions through ultrasonic dispersion technology. The use of dispersing equipment can disperse these components in the water in the form of very small droplets. The active ingredients dispersed by ultrasonic waves can produce stable compatibility with liquids and improve their own bioavailability. Therefore, they can be easily injected into food and beverage products without affecting their shelf stability and ensuring that biologically active substances are quickly and completely absorbed by the body.


2. Chemical industry
Dispersing powders into liquids is an important step in formulating various products such as paints, inks, coatings and other polishing media. Ultrasonic dispersion equipment can achieve uniform dispersion, depolymerization and grinding in laboratories, workbenches and industrial scales.

Paint is not only used for house decoration purposes, but also as a coating for automobiles, construction, mechanical engineering and many other industries. The color and coating of paint can be improved using ultrasonic dispersion method.

Ultrasonic dispersion can be used for toner in laser printers and copiers. It can achieve the best printing results while maintaining vivid colors, while achieving low consumption and the best adhesion to all types of printing paper. The development of the smallest possible particle size is an important step to obtain high-quality ink products. Ultrasound is an effective dispersion method. Unlike other technologies, it is cheaper and easier to operate and maintain.


3. Medical field
The pharmaceutical industry is looking for ways to solve the problem of poor water solubility of biologically active substances, resulting in low bioavailability and delayed onset of action. Laboratories, workbenches, and industrial ultrasonic liquid dispersion equipment provide a simple and effective method of producing uniform nanoparticles by exposing materials to high-intensity ultrasonic cavitation and extremely strong shear forces. These forces are also essential for the cell disruption (lysis) process, which is an important step in extracting pharmaceuticals (such as recombinant proteins, medicinal oils, and other biologically active substances) from yeast, bacteria and plant cells.
