Ultrasonic sonochemical dispersion principle:
Acoustic chemistry is an emerging cross-disciplinary, mainly referring to the use of ultrasound to accelerate chemical reactions or trigger new reaction channels to increase the yield of chemical reactions or obtain new chemical reaction products. The main power of the sonochemical reaction comes from acoustic cavitation, which comes from the extreme physical conditions such as high temperatures (greater than 5,000K), high pressure (greater than 2.03×108Pa), shock waves, or micro-jets that accompany the implosion of a cavitation bubble.
2. Application of sonochemistry The application of sonochemistry is very broad and can be roughly classified into nine categories: biochemistry, analytical chemistry, catalytic chemistry, electrochemistry, photochemistry, environmental chemistry, mineral chemistry, extraction and separation. , synthesis and degradation.
When ultrasonic waves are used in liquid media, a series of mechanical, thermal, optical, electrical and chemical effects are produced through mechanical action, cavitation and thermal action. In particular, high-powered ultrasonic waves generate strong cavitation, which results in localized high-temperature, high-pressure, vacuum, and micro-jets. Ultrasound technology as a physical tool and tool can produce a series of near-extreme conditions in the media commonly used in chemical reactions. This energy can not only stimulate or promote many chemical reactions, accelerate the speed of chemical reactions, and can even change some of the The direction of chemical reactions produces some unexpected effects and miracles. It is generally believed that the occurrence of the above phenomenon mainly stems from the mechanical action and cavitation of ultrasound, which is the result of their changing reaction conditions and environment. Mechanical action - the introduction of ultrasound into the chemical reaction system, ultrasound can make the material for intense forced movement, resulting in a one-way force to accelerate the transfer of the material, diffusion, can replace the mechanical stirring, can make the material from the surface peeling, so that the interface update. Cavitation - In some cases, the generation of ultrasonic effects is related to the cavitation mechanism. Acoustic cavitation refers to a series of dynamics of tiny bubbles (holes) that exist in the liquid under the action of sound waves. The process of learning: oscillation, expansion, contraction and even collapse. In the event of cavitation, the local state of the liquid undergoes a great change and extreme heat and pressure are generated. It provides a new and very special physical and chemical environment for chemical reactions that are difficult or impossible to achieve under normal conditions.Hangzhou Success Ultrasonic Equipment Co.,Ltd.
