Preparation technology of solder powder - ultrasonic spraying

Preparation process of solder powder - Ultrasonic spraying - Ultrasonic nozzle - YMUS ultrasonic spraying

From the production practice, in many metal powder preparation technology, atomization is the most important preparation method of solder powder at present.

Ultrasonic atomizing spraying is a new pulverizing method. The ultrasonic transducer in the ultrasonic atomizer is the core component of the whole system. Under the control of the high-frequency power supply, the electric oscillation is converted into the ultrasonic mechanical vibration of the same frequency, and then the amplitude is amplified by the amplifying rod to drive the atomization Angle end face to make ultrasonic vibration to form the atomization. Its function is similar to the atomizing nozzles and centrifugal atomizing turntables. Its design and production directly affect the particle size and particle size distribution range of atomized powder.

From the principle of ultrasonic atomization, the main factors affecting ultrasonic atomization are the working frequency of ultrasonic generator, the natural vibration frequency of the crystal horn and atomization Angle of the transducer, the material of the atomization Angle, the amplitude of ultrasonic vibration, the superheat and flow of molten solder, the atomization protection atmosphere and other parameters. The influence and control of the superheat and flow rate of molten solder, atomizing protective atmosphere and other parameters on the solder powder are basically consistent with the above two atomizing methods.

YMUS ultrasonic atomizing nozzle, longitudinal, transverse and tic-tac-toe spraying track. YMUS Spray equipment can be extended to continuous functional coatings of any width. The solder powder prepared by ultrasonic atomization process has the best effect, the powder particle is small and the spraying yield is high.
