    Short Description

    Ultrasonic atomization is a new type of powder making method developed in recent years. Ultrasonic waves are used to atomize molten metal into powder. The solder powder (indium powder, etc.) prepared by ultrasonic atomization has good sphericity, narrow powder particle size distribution, and low oxygen content.

    Metal powder can be produced by ultrasonic atomization. When the ultrasonic power generator excites the ultrasonic transducer, the ultrasonic tool head as the transducer load vibrates, and the molten metal solution is atomized by ultrasonic vibration. Then the droplet-shaped metal particles cool and solidify in the air and fall into the powder collecting tube. They are collected to become metal powder.

    Principle

    The principle of ultrasonic powder making machine is that the ultrasonic driving power supply is connected to the ultrasonic transducer set in the shell through a cable. The transducer converts the high-frequency sound waves generated by the driving power supply into high-frequency mechanical energy and works, and performs longitudinal high-frequency vibration. The frequency of the high-frequency vibration is equivalent to the frequency of the AC current of the driving power supply. The vibration output end of the transducer is connected to the horn. This longitudinal upward and downward vibration is transmitted to the atomization surface by the horn to generate standing waves. The horn has the function of amplifying the output amplitude of the transducer to the required degree.

    When the molten metal liquid passes through the atomization surface, it is broken into uniform micron-sized droplets and mist to achieve atomization. The atomized micron-sized droplets are thrown out of the atomization surface under the action of the rotating centrifugal force and standing waves of the atomization surface, and are rapidly solidified when cooled by air to form micron-sized metal solid particles. Collecting these particles is the metal powder to be prepared. Moreover, in the ultrasonic atomization process, the size of the micron-sized droplet mist can be accurately controlled, thereby accurately controlling the size of the metal powder. Ultrasonic tin atomization uses the energy of ultrasound to break up the molten tin to form tiny particles ranging from a few microns to more than 100 microns. This metal spray technology is widely used in the fields of industry and research and development, and will gradually replace traditional pressure spraying.
