Description

liquid into small bubbles. Another reason is that strong tensile stress in the fluid "tear" into a hollow, referred to as cavitation. Hole for the liquid vapor or another gas dissolved in the liquid, and perhaps even a vacuum. Because of small bubbles formed by the cavitation will vary with the vibration of the surrounding medium constant motion, grew up, or suddenly burst. Burst suddenly stormed the fluid surrounding the air bubble produced by high temperature and high pressure, at the same time produces a shock wave. Internal friction can form accompanied by cavitation effect charge, and luminescence phenomenon resulting from the internal discharge in bubbles. In a liquid ultrasonic processing technology are related to the cavitation.
(3) heat effect. Due to the ultrasonic frequency is high, energy is large, when absorbed by the medium can have a significant effect.
4. Chemistry. The role of ultrasound can make or speed up certain chemical reactions happen. For example, the pure distilled water after ultrasonic treatment produce hydrogen peroxide; Is dissolved nitrogen in the water after ultrasonic treatment produce nitrite; Dye in aqueous solution after ultrasonic treatment can change color or fade. These phenomena occurred always accompanied with cavitation. Ultrasound can also accelerate the hydrolysis of many chemicals, decomposition and polymerization process. Ultrasonic light chemical and electrochemical process has obvious influence. Various amino acids and other organic material solution after ultrasonic treatment, the characteristic absorption spectrum band disappeared and general absorption of homogeneously, this shows that the cavitation effect makes the molecular structure has changed.    skype  hong****6      *&*; *@********************ml>
