Principle of ultrasonic vibrator : ultrasonic technology is mainly used as a physical means and tool, which can form a series of conditions close to extreme critical conditions when producing chemical reactions. This kind of energy can not only stimulate chemical reactions, accelerate the speed and efficiency of chemical reactions, but also change the properties of some chemical reactions, making the original chemical components produce some unexpected effects and functions, This is called sonochemistry. Almost all chemical reactions can use sonochemistry as physical assistance, such as extraction and separation, synthesis, biodiesel production, treatment of microorganisms, degradation of toxic organic pollutants, biodegradation, crushing, dispersion and coagulation of biological cells, etc. Therefore, the ultrasonic vibrator can not only be used to clean the object and peel the dirt off the surface of the object, but also contribute to the further success of scientific research.

Working principle and function of ultrasonic vibrator

The following describes the three functions of ultrasonic vibrator.

Ultrasonic dispersion: the process of dispersing and agglomerating the particles in liquid through the "cavitation" effect of ultrasonic in liquid. Ultrasonic dispersion can be divided into emulsion dispersion, i.e. liquid and liquid dispersion, and suspension dispersion, i.e. solid and liquid dispersion. Its function has been applied in many fields. Among them, the dispersion application of ultrasonic wave for suspension, such as the dispersion of titanium oxide to water or solvent in coating and plastic industry, the dispersion of dye to molten paraffin, the dispersion of drug particles in pharmaceutical industry, and the dispersion of powder emulsion in food industry, etc.

Ultrasonic extraction: ultrasonic extraction and separation is a scientific and reasonable new extraction process based on the existing state, polarity and solubility of effective components and groups of effective components in materials. It makes the solvent spread all over the surface of solid materials quickly, and dissolves the organic components contained in the materials as completely as possible After a complete process, the final chemical components can be obtained.

Ultrasonic emulsification: under the action of ultrasonic energy, ultrasonic emulsification refers to the process of making two (or more) immiscible liquids mix evenly to form a dispersion system, one of which is evenly distributed in the other liquid, and then forms an emulsion liquid. The physical mechanism of crushing insoluble solids (or liquids) is the cavitation of ultrasound. Ultrasonic cavitation effect refers to that under the action of ultrasonic, a large number of bubbles will be generated in the liquid, small bubbles will gradually increase with the ultrasonic vibration, and then burst and split suddenly, tens of thousands of small bubbles will increase and burst again and again, when the bubble collapses rapidly, high temperature and high pressure will be generated in the bubble, and the liquid around the bubble will burst into the bubble at a high speed, and the liquid near the bubble will collapse Strong local oscillation wave is produced in the body, which also forms local high temperature and high pressure, resulting in ultrasonic crushing and emulsification.
