The working principle and function of ultrasonic vibrating rod

Principle of ultrasonic vibrating rod: Ultrasonic technology, as a physical means and tool, can form a series of conditions close to the critical state when a chemical reaction occurs. This energy can not only stimulate chemical reactions, accelerate the speed and efficiency of chemical reactions, but also change the nature of certain chemical reactions, so that the original chemical composition can produce some satisfactory results. This is called sonochemistry. Almost all chemical reactions can be assisted by sonochemistry, such as extraction and separation, synthesis, biodiesel production, microbial control, toxic organic pollutant degradation, biodegradation, biological cell fragmentation, dispersion and agglomeration. therefore,Ultrasonic vibratorNot only can it be used to clean the dirt on the surface of the object, but also contribute to the further success of scientific research. The three functions of the ultrasonic vibrator are described below. Ultrasonic dispersion: The process of dispersing and agglomerating particles in the liquid through the "cavitation" effect of ultrasonic waves in the liquid. Ultrasonic dispersion can be divided into emulsion dispersion, namely liquid and liquid dispersion, and suspension dispersion, namely solid and liquid dispersion. Its functions have been practically applied in many fields. Among them, the ultrasonic dispersion applications of suspensions, such as the dispersion of titanium dioxide in water or solvents in the coating and plastic industries, the dispersion of dyes in molten paraffin, the dispersion of drug particles in the pharmaceutical industry, and the dispersion of powder emulsions in the food industry, etc. .
Ultrasonic extraction: Ultrasonic extraction and separation is a scientific and reasonable new technology. It is designed based on the existence, polarity and solubility of the effective components and effective components in the substance, so that the solvent can quickly diffuse to all corners of the solid substance. The organic components contained in the substance are completely dissolved in the solvent as much as possible to obtain a multi-component mixed extract, and then the chemical components in the extract are separated by an appropriate separation method, and then refined and purified. After such a complete process, the monomer chemical composition can be obtained.
Ultrasonic emulsification: Ultrasonic emulsification refers to mixing two (or more than two) insoluble liquids uniformly under the action of ultrasonic energy to form a dispersion system, one of which is evenly distributed in the other liquid, and then forms an emulsion process. The physical mechanism for breaking up insoluble solids (or liquids) is ultrasonic cavitation. The ultrasonic cavitation effect means that a large number of bubbles will be generated in the liquid under the action of ultrasound. Small bubbles will gradually increase with the ultrasonic vibration, and then suddenly burst and split. Tens of thousands of small bubbles will continue to grow and burst. When the bubble collapses rapidly, high temperature and high pressure are generated in the bubble, and the liquid around the bubble rushes into the bubble at a high speed. The liquid around the bubble generates a strong local oscillation wave near the bubble, forming local high temperature and high pressure to produce ultrasonic pulverization and emulsification.
