    There are many types of ultrasonic, including ultrasonic plastic welding machine, ultrasonic plastic welding machine, ultrasonic plastic welding machine, ultrasonic cleaning machine, ultrasonic welding machine, ultrasonic plastic cutting machine and so on. There are also fusion splicers, fusing machines, and high-frequency plastic fusion splicers.

    A brief introduction to the principle of ultrasonic and high-frequency, the difference between them is that high-frequency and ultrasound are two different concepts, high-frequency refers to electromagnetic waves with a frequency greater than 100kHz, and ultrasonic refers to sound waves with a frequency of more than 20 kHz. The high-frequency welding principle, welding principle and ultrasonic wave are also different, the high-frequency electromagnetic field is generated by the self-excited oscillator of the electron tube, so that the high-frequency electric field between the upper and lower electrodes of the processed plastic, its internal molecules produce distance force motion friction, and obtain its welding purpose and welding effect under the pressure of the mold. Ultrasonic uses the principle of frictional heat generation to generate a large amount of heat to achieve the purpose of welding and welding.

    High-frequency application fields are wide, so there are high-frequency plastic welding machines, high-frequency plastic fusing machines, high-frequency folding box indentation machines, high-frequency embossing machines, high-frequency heating machines, etc.

    Summary. Hello, no. Ultrasonic wave is a sound wave, which is a sound wave with a frequency higher than 20,000 hertz, it has good directionality, strong penetrating ability, easy to obtain more concentrated sound energy, and has a long propagation distance in water, which can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, sterilization and disinfection, etc.

    Are ultrasound high wave frequencies?

    Hello, no. Ultrasonic wave is a sound wave, which is a sound wave with a frequency higher than 20,000 hertz, it has good directionality, strong penetrating ability, easy to obtain more concentrated sound energy, and has a long propagation distance in water, which can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, sterilization and disinfection, etc.

    It's not a high-frequency ** instrument.

    Can you play with mobile phones?

    **When.

    But why do you need to take out the metal when you do ultrasound?

    What do you mean?

    No, for safety, avoid interference.

    Since it's not a high frequency, you can play with your phone.

    What are the implications?

    No, mobile phones can interfere with ultrasound. Just do it according to the requirements of the hospital.

    1. The frequency is different.

    1) Ultrasound: When the vibration frequency of the sound wave is greater than 20000Hz, the human ear cannot hear it. Ultrasound gets its name from the fact that its lower limit of frequency is approximately equal to the upper limit of a person's hearing. Therefore, we call sound waves with frequencies higher than 20,000 Hz "ultrasound".

    2) High-frequency sound waves: The frequency of sound waves refers to the number of times particles in the wave train vibrate per unit time. Measured in hertz (Hz) and describes the number of cycles per second. The frequency of sound waves that can be heard by the human ear is 20 20000 Hz.

    2. The role is different.

    1) Ultrasound: Ultrasonic inspection, the wavelength of ultrasonic waves is shorter than that of general sound waves, has good directionality, and can penetrate opaque substances, this characteristic has been widely used in ultrasonic flaw detection, thickness measurement, ranging, remote control and ultrasonic imaging technology.

    2) High-frequency waves: In the field of electronic technology, high-frequency waves are defined in radio technology as radio waves with frequency bands from 3MHz to 30MHz. HF is mostly used for civil radio broadcasting and shortwave broadcasting.

    It is less resistant to radio waves emitted by electronic devices, so it is often interfered with. High-frequency waves are commonly used in civil radio broadcasting, short-wave broadcasting, and HF long-range radar.

    3. Different application fields.

    1) Ultrasonic: Ultrasonic treatment, using the mechanical action, cavitation, thermal effect and chemical effect of ultrasonic, can be used for ultrasonic welding, drilling, solid crushing, emulsification, degassing, dust removal, descaling, cleaning, sterilization, promoting chemical reactions and biological research, etc., which has been widely used in various departments such as industry and mining, agriculture and medical treatment.

    2) High-frequency waves: they will exist in different fields, such as quantum mechanics, sound waves, light waves, elastic waves and electromagnetic waves, which have a wide range of applications.

    High-frequency machine and ultrasonic machine are two different types of equipment.

    The working principle of the high-frequency machine is to penetrate the upper and lower heating together to achieve the effect of welding! The ultrasonic machine uses an ultra-high frequency vibrating welding head under moderate pressure to cause friction and heat sealing of the joint surface of two plastics and instantaneous welding.

    The high frequency used in high-frequency machines and ultrasound are two different concepts, high-frequency refers to electromagnetic waves with a frequency greater than 100kHz, and ultrasonic refers to sound waves with a frequency of more than 20 kHz. High-frequency is the use of high-frequency electromagnetic field to make the internal molecules of the material collide violently with each other to produce high temperature to achieve the purpose of welding and welding, while ultrasonic is the use of the principle of friction heat generation to generate a large amount of heat to achieve the purpose of welding and welding.

    High frequency is the use of high-frequency electromagnetic field to make the internal molecules of the material collide violently with each other to produce high temperatures, so as to achieve the purpose of welding and welding. The high-frequency machine is the preferred equipment for plastic heat sealing, which uses a high-frequency electric field to make the molecules inside the plastic oscillate to produce heat energy and fuse various products.

    The high-power high-frequency machine uses high-voltage rectifier self-excited electron tube oscillation to instantly generate electromagnetic electric field to change plastic molecules, and under the action of air pressure external force and mold, it can achieve the effects of welding, cutting, sealing and embedding; The operation is easy to understand and easy to learn, the efficiency is many times that of ordinary small machines, and it is suitable for the welding and cutting of large plastic products, with a simpler process and a more perfect effect.

    Ultrasonic waves use the principle of frictional heat generation to generate a large amount of heat to achieve the purpose of welding and welding. The ultrasonic welding machine conducts ultrasonic waves to the plastic processing parts through the welding head, so that the two plastic joint surfaces are subjected to ultrasonic action and produce violent friction, and the friction heat melts the plastic joint surface to complete the gluing.

    This technology has the advantages of fast speed, strong welds, and more importantly, it can automate the production and processing of plastic products. Ultrasonic plastic welding machine can be used for plastic welding, embedding, forming, riveting, spot welding, excision, suturing and other operations. As long as the sonotrode is changed, one machine can be used for multiple applications.

    Theoretically, infrasound, sonic, and ultrasound can all be used in sonar, but penetrating infrasonic waves are the best, ultrasound is the worst, directional ultrasound is the best, and device volume infrasound is the largest.

    My personal analysis: Generally, marine sonar uses more sound waves, and the performance is in the middle, while towed array sonar or submarine side sonar may use infrasound.

    As for the specific frequency of the sonar and the frequency combination, this is a national defense secret with a high level of secrecy, and all countries are tight-lipped, and once leaked, it will cause irreparable losses to their own naval forces.

    As for the damage of marine mammals, the main reason is that the sonar frequency is comparable to their physiological frequency, and this problem is also present not only in submarines, but also in other commercial sonars. This contradiction is difficult to solve, and theoretically it can only be solved unless human beings do not face war, do not have to explore the oceans, or invent more effective means of detection (of course, if we can invent new methods and equipment, I think it will be fine to win a few Nobel Prizes).

    High-frequency sound waves don't seem to have a range.

    Ultrasound Sound waves with frequencies higher than 20,000 hertz are called "ultrasounds".
