Ultrasound examination: Ultrasound examination. The wavelength of ultrasonic waves is shorter than that of general sound waves, it has good directionality, and it can penetrate opaque materials. This characteristic has been widely used in ultrasonic flaw detection, thickness measurement, distance measurement, remote control and ultrasonic imaging technology. Ultrasound imaging is a technique that uses ultrasound to present the image of the interior of an opaque object.

Ultrasonic treatment: Utilizing the mechanical action, cavitation, thermal effect and chemical effect of ultrasound, ultrasonic welding, drilling, solid pulverization, emulsification, degassing, dust removal, descaling, cleaning, sterilization, promotion of chemical reactions and For biological research, etc., it has been widely used in various sectors such as industry and mining, agriculture, and medical care.

Basic research: After ultrasonic waves act on a medium, an acoustic relaxation process occurs in the medium. The acoustic relaxation process is accompanied by the transport process of energy between the respective electrical degrees of the molecules, and shows the absorption of acoustic waves on a macroscopic level (see acoustic waves) . The properties and structure of matter can be explored through the absorption law of matter to ultrasound, which constitutes the acoustic branch of molecular acoustics.

Medical ultrasound examination: The working principle of medical ultrasound examination is similar to that of sonar, that is, the ultrasonic wave is emitted into the human body. When it encounters an interface in the body, reflection and refraction occur, and it may be absorbed and attenuated in human tissue. . Because the shape and structure of various tissues in the human body are not the same, the degree of reflection, refraction and absorption of ultrasonic waves is also different. they. ---Longgang ultrasonic spot melting machine

Ultrasonic degreasing: The degreasing process in which the parts with oil stains are placed in the degreasing liquid and the degreasing process is under the action of a certain frequency of ultrasonic field is called ultrasonic degreasing. The introduction of ultrasonic waves can strengthen the degreasing process, shorten the degreasing time, improve the degreasing quality, and reduce the consumption of chemicals.

Ultrasonic flaw detector: Using the characteristics of strong ultrasonic penetration ability, an ultrasonic flaw detector can be made to detect whether there are bubbles or cracks in the metal.

Glass parts: The descaling of glass and ceramic products is a hassle. If these items are put into the cleaning solution and then passed through ultrasonic waves, the violent vibration of the cleaning solution will impact the dirt on the items, which can be cleaned quickly. ---Longgang ultrasonic spot melting machine

Introduction to Ultrasound

Ultrasonic is a sound wave with a frequency higher than 20000 Hz. It has good directionality, strong penetrating ability, easy to obtain concentrated sound energy, and travels far in water. It can be used for distance measurement, speed measurement, cleaning, welding, gravel , sterilization, etc. There are many applications in medicine, military, industry and agriculture. Ultrasound is named because its lower frequency limit is greater than the upper limit of human hearing.

Scientists refer to the number of vibrations per second as the frequency of sound, and it is measured in hertz (Hz). The frequency of sound waves that our human ear can hear is 20Hz-20000Hz. Therefore, we call sound waves with frequencies above 20,000 Hz "ultrasonic". Ultrasound frequencies typically used for medical diagnosis are 1 MHz-30 MHz. ---Longgang ultrasonic spot melting machine

Features of Ultrasound

When the ultrasonic wave propagates, the directionality is strong, and the energy is easy to concentrate.

Ultrasound can travel in a variety of different media, and can travel far enough distances.

The interaction between ultrasound and the sound transmission medium is moderate, and it is easy to carry information about the state of the sound transmission medium for diagnosis or to have effects and treatment on the sound transmission medium. ---Longgang ultrasonic spot melting machine

Ultrasound can effectively propagate in gas, liquid, solid, solid solution and other media.

Ultrasound can transmit strong energy.

Ultrasonic waves produce reflection, interference, superposition and resonance phenomena.

Fundamentals of Ultrasound

Ultrasound is a part of sound waves. It is a sound wave that cannot be heard by the human ear and has a frequency higher than 20KHZ. Earth exists in nature, and many animals can transmit and receive ultrasonic waves, among which bats are the most prominent, which can use weak ultrasonic echoes to fly in the dark and capture food. But ultrasound also has its special properties' such as higher frequency and shorter wavelength, so it also has similarities with light waves with very short wavelengths. ---Longgang ultrasonic spot melting machine
