120kHz Ultrasonic Spray Nozzle: High Frequency Enables A New Experience in Precision Atomization

In the field of ultrasonic atomization technology, 120kHz frequency nozzles, with their refined atomization capabilities and stable performance, have become core components in high-end fields such as precision manufacturing and biomedicine. Based on high-frequency vibration, they overcome the limitations of traditional atomization technology, achieving precise control and efficient deposition of micron-sized droplets.

The working principle of the 120kHz ultrasonic spray nozzle is based on the piezoelectric effect. A high-frequency generator converts electrical energy into mechanical vibrations of the corresponding frequency, which are transmitted to the atomization surface, causing a standing wave to form on the liquid surface. When the vibrational energy overcomes the surface tension of the liquid, the liquid is broken into uniform droplets. Combined with a vortex airflow shaping design, a stable spray pattern can be formed. Compared to low-frequency nozzles, the 120kHz high-frequency characteristics result in finer and more uniform atomized particles, with a median particle size as low as 18μm, and the droplet movement speed is gentle, effectively avoiding splashing and agglomeration.

This type of nozzle boasts multiple core advantages. In terms of control precision, the flow rate can be precisely adjusted to 0.5-8 ml/min, and the spray width ranges from 3-7 cm. Combined with phase tracking, it enables precise control of coating thickness and coverage, improving material utilization by more than four times compared to traditional two-fluid spraying. Structurally, it utilizes corrosion-resistant titanium alloy, combining excellent acoustic performance with a long service life. Its self-cleaning properties effectively prevent clogging, reducing maintenance downtime. In terms of adaptability, it can handle various liquids with viscosity <30 cps and solid-liquid ratio <25%, including solutions and suspensions, meeting diverse application needs.

Thanks to these characteristics, the application scenarios of the 120kHz ultrasonic spray nozzle continue to expand. In the energy sector, it can be used for uniform coating of proton exchange membranes in fuel cells and solar cells, improving device performance and lifespan. In the biopharmaceutical sector, it is suitable for spray drying processes of nasal drug delivery powders, enabling stable control of particle characteristics and facilitating large-scale production. In the electronics sector, it can achieve the preparation of ultra-thin coatings for photoresists and polyimide films, adapting to substrates with complex geometries.

As a typical representative of high-frequency ultrasonic atomization technology, the 120kHz nozzle, with its core advantages of "precision, efficiency and stability", provides a reliable solution for the upgrading of atomization processes in the high-end manufacturing field, and promotes technological innovation in fields such as precision coating and precise drug delivery.
