Ultrasonic dispersers and ultrasonic cleaners are two commonly used ultrasonic devices, and there are some differences in their applications and principles.
First, let's learn about ultrasonic dispersers. Ultrasonic dispersers are mainly used in liquid media, separating impurities such as gases and solid particles in liquids through high-frequency vibration. It is commonly used in the preparation of high-purity liquids, the removal of impurities from liquids, and the conduct of chemical reactions. The principle of ultrasonic disperser is to use the vibration of ultrasonic waves in the liquid to produce pressure fluctuations, forming alternating changes in negative pressure and positive pressure, so as to separate gases and solid particles from the liquid.
2024 Book of Answers Unlike ultrasonic dispersers, ultrasonic cleaners are mainly used to clean various surfaces and objects, such as metal, glass, ceramics, plastics, etc. It uses high-frequency vibration and micro-jets to powerfully clean the surface of the object to remove dirt, oil stains, rust, etc. on the surface. The principle of the ultrasonic cleaning machine is to use the vibration of ultrasonic waves in the liquid to produce tiny bubbles, which generate high pressure and high temperature at **, so as to peel off the dirt on the surface of the object and quickly wash away by the liquid. In general, both ultrasonic dispersers and ultrasonic cleaners use the vibration of ultrasonic waves to work, but their uses and application fields are different. Ultrasonic dispersers are mainly used to separate gases and solid particles in liquids, while ultrasonic cleaners are mainly used to clean surfaces. In practice, it is necessary to select the right equipment for the specific needs.
