Is high power ultrasound harmful to humans? Ultrasonic mold manufacturers as a company familiar with ultrasonic technology, today we want to talk about this topic. In fact, different frequencies and different sound levels are harmful to different individuals. Because ultrasound has a strong penetration of both solids and liquids, low-dose ultrasound is a potential carcinogenic and teratogenic factor. When the energy is large, the particles of the material can be vibrated at a high frequency, and the local energy can also be converted into heat energy to increase the local temperature. High-intensity pulsed ultrasonic waves can cause air bubbles to contract, swell, and violently explode when they are propagating in liquids containing micron-sized small bubbles. This phenomenon is called "cavitation."
The maximum output intensity of some clinically used ultrasound imaging diagnostics has reached 1 kW / cm 2 , not long ago, the famous American super biophysical expert Katstanson pointed out. This intensity is sufficient to cause transient cavitation in the organism. For organisms, when transient cavitation occurs, cells near the explosion bubble will be damaged. Generally speaking, in most organs and biological fluids in the human body, damage to a small number of cells will not harm the human body.
Dongguan Yihui Machinery Equipment Co., Ltd. has been engaged in the ultrasonic industry for many years and its performance is relatively stable and mature. The welding equipment mainly adopts mature technology such as Taiwan's self-excited oscillation circuit, and the output is strong and stable, the protection is perfect, and it is sturdy and durable. The core components such as transducers are imported from Japan and West Germany, with long service life and excellent performance. It is a good helper for your production! Welcome to inquire!
