Ultrasonic cleaning technology overview and principle introduction
I. Ultrasound Technology Overview Ultrasound technology is one of the common technologies based on physics, electronics, machinery and materials science. Ultrasound technology is accomplished through the physical processes of ultrasonic generation, propagation, and reception. Ultrasonic waves have characteristics such as bunching, orientation, reflection, and transmission. According to the different sizes of ultrasonic vibration radiation, it can be roughly divided into: Second, the principle of ultrasonic cleaning Ultrasonic cleaning machine uses ultrasonic clear technology: ultrasonic cleaning is a physical cleaning, the cleaning liquid is placed in the tank, and ultrasonic waves are applied in the tank. Since the ultrasonic wave is a dense vibration wave like the sound wave, the pressure of the medium alternates during the propagation process. In the negative pressure region, a force of tearing is generated in the liquid, and a bubble of vacuum is formed. When the sound pressure reaches a certain value, the bubble rapidly grows, and in the positive pressure region, the bubble is crushed and closed due to the pressure. At this time, the liquid collides with each other to generate a strong shock wave. Although the displacement and speed are very small, the acceleration is very large, and the partial pressure can reach several thousand atmospheres. This is the so-called cavitation effect.
Sucralose is an artificial Sweetener. The majority of ingested sucralose is not broken down by the body, so it is noncaloric. The commercial success of sucralose-based products stems from its favorable comparison to other low-calorie sweeteners in terms of taste, stability, and safety . Sucralose is approximately 600 times as sweet as sucrose (table sugar)

1. The application of ultrasonic power to change the power of an object or physical property is called power ultrasonic. For example, a large enough energy is generated in the liquid to generate cavitation, which can be used for cleaning and emulsification. Ultrasonic cleaning machines are also gaining more and more popularity. 2. Several information is obtained by ultrasonic waves, and communication applications are obtained. The ultrasonics are detected. For example, the thickness of the object is measured by pulse reflection of the ultrasonic waves in the medium.
