What chemical changes can ultrasonic sonochemical equipment play?

As a physical means and tool, ultrasonic chemical treatment technology can generate a series of near-extreme conditions in the medium of chemical reaction. 

This energy can not only stimulate or promote many chemical reactions, speed up chemical reactions, but also change certain The direction of these chemical reactions produces some unexpected effects and miracles, which is sonochemistry. Ultrasonic chemistry can be applied to almost all chemical reactions, such as extraction and separation, synthesis and degradation, biodiesel production, treatment of microorganisms, degradation of toxic organic pollutants, biodegradation treatment, biological cell crushing, dispersion and coagulation, etc. Another outstanding advantage of ultrasonic sonochemical equipment is that it has no moving parts, no electromagnetic radiation, and is very simple to install and fix. 

It is especially suitable for applications in high pressure, high temperature, toxic and explosive environments. Another application of ultrasonic sonochemical equipment is in the field of sewage treatment and scale prevention and descaling. Many experts and scholars have done a lot of research and experiments, which proves that ultrasonic waves are effective in the anti-scaling and descaling of pipelines and equipment.

Ultrasonic has been widely used in industrial manufacturing industry, such as ultrasonic welding machine, ultrasonic plastic welding machine, ultrasonic cleaning machine, etc. The propagation laws of ultrasonic waves in the medium, such as reflection, refraction, diffraction, and scattering, are not fundamentally different from the laws of audible sound waves. But the wavelength of ultrasound is very short, only a few centimeters, or even a few thousandths of a millimeter.


The action of the ultrasonic waves of the ultrasonic welding machine can promote or accelerate certain chemical reactions.

1. Pure distilled water produces hydrogen peroxide after ultrasonic treatment;

2. Nitrous acid is produced after ultrasonic treatment of water dissolved in nitrogen;

3. The aqueous solution of dye will change color or fade after ultrasonic treatment.

The occurrence of these phenomena is always accompanied by cavitation. Ultrasound can also accelerate the hydrolysis, decomposition and polymerization processes of many chemical substances, and ultrasound also has a significant impact on photochemical and electrochemical processes. After ultrasonic treatment of aqueous solutions of various amino acids and other organic substances, the characteristic absorption spectral bands disappeared and showed uniform general absorption, which indicated that the molecular structure was changed by cavitation.
