　　What are the main mechanical effects of a composite embossing machine?

　　In specific applications, the Shenzhen sanitary composite embossing machine mainly has mechanical effects (such as particle vibration displacement, velocity, acceleration, sound pressure and other mechanical quantities of the sound transmission medium), thermal effects (part of the energy of sound waves is absorbed by the medium as heat energy during propagation) and cavity effects. In the past, complex mechanical parts required long-term manual cleaning in dirty environments, requiring a significant amount of manual labor. After the application of ultrasonic cleaning machines, not only has the working environment been improved and the harm of manual cleaning to workpieces been eliminated, but the labor intensity has also been reduced. On the basis of greatly improving cleaning accuracy, the cleaning time has been reduced to one fourth of the original.

　　Of course, not all gas nuclei that appear in liquid management can develop a cavity effect. Only when the external ultrasonic frequency is the same as the natural frequency of the gas nucleus, can cavity effect research continue to occur. It is also influenced by other factors in society, such as the intensity of sound waves, temperature changes in liquid media, and vapor pressure of different media. The appropriate ultrasonic frequency for inducing cavity effect is 20kHz to 80kHz. Excessive frequency makes it difficult to control the formation of cavity effects, and even if it does occur, a large amount of energy needs to be provided. Moreover, most of the energy in China is converted into thermal energy, which does not significantly increase the ambient temperature of the medium.

　　The application of low-intensity ultrasound will not cause any changes in the state of the medium, only high-intensity ultrasound can have a strong impact on the medium, causing cavity effects. For most chemical reactions, the reaction rate increases with the increase of "sound intensity". However, the intensity of ultrasound is affected by the temperature of the medium.
