Ultrasonic spraying technology uses ultrasonic vibration to evenly spray flux onto the solid surface, improving welding quality, saving more than 40% of raw materials, reducing VOCs emissions by more than 80%, reducing pollution, and controlling spraying with high precision. It is widely used in electronic welding and is expected to be promoted to more fields in the future.
With the continuous development of industrial technology, the requirements for welding technology are increasing day by day. As an indispensable key material in the welding process, the performance and application effect of flux directly affect the quality and efficiency of welding. Ultrasonic spraying technology uses the energy of ultrasound to break liquid flux into tiny droplets and accelerate them to spray on the solid surface. This process does not rely on external airflow to form an atomization effect, but forms a stable droplet stream through ultrasonic vibration. The ultrasonic generator converts electrical energy into ultrasonic signals, which are converted into mechanical vibrations through ultrasonic transducers, and then the mechanical vibrations are transmitted to the liquid flux at the ultrasonic nozzle, so that it forms a stable liquid column and breaks into tiny droplets at the tip of the nozzle. These droplets are then evenly covered on the solid surface at the same speed, size and shape, achieving efficient and uniform spraying.

Advantages of ultrasonic spray flux

1. Uniform spraying: Because ultrasonic spraying technology does not rely on external airflow, but forms a stable droplet flow through ultrasonic vibration, it can accurately control the spraying flow, speed and direction to ensure uniform spraying. Whether it is a flat surface or a curved surface, whether it is a large area or a small area, the ideal spraying effect can be achieved.

2. Save raw materials: The ultrasonic spraying method only requires a small amount of carrier gas to assist in forming a stable droplet flow, which greatly reduces the loss of raw materials. According to statistics, compared with the traditional two-fluid or air pressure spraying method, the ultrasonic spraying method can save more than 40% of raw materials and improve the utilization rate of raw materials.

3. Reduce VOCs emissions: Because ultrasonic spray technology reduces the loss of raw materials, it also reduces the emissions of solvents and active substances. The emission of VOCs (volatile organic compounds) is significantly reduced, reducing environmental pollution. According to statistics, ultrasonic spraying methods can reduce VOCs emissions by more than 80% compared to traditional methods.

4. Reduce pollution: The number of atomized droplets generated during the ultrasonic spraying process is small, and the flux solvent and active substances contained in the droplets are not easily diffused into the surrounding environment. This not only reduces environmental pollution, but also reduces the harm to human health.

5. High-precision spraying: Ultrasonic spraying equipment can accurately control the frequency, power and phase of ultrasonic waves, as well as the shape, size and angle of the nozzle, thereby achieving high-precision spraying. This is particularly important for welding processes that require precise control of coating thickness and uniformity.
