What Are The Advantages Of 40k Ultrasonic Atomizing Nozzle?

(I) Fine and Uniform Atomized Particles, Superior Coating Quality

The fineness and uniformity of atomized particles are core indicators for evaluating the performance of an atomizing nozzle, and also the most prominent advantage of the 40kHz ultrasonic atomizing nozzle. Utilizing 40kHz high-frequency vibration technology, this nozzle can atomize liquids into tiny particles ranging from a few micrometers to 50 micrometers, with a median particle size of approximately 44µm. The particle size distribution is concentrated, with no large particle splashing, and the droplet uniformity far exceeds that of traditional pressure nozzles. This fine and uniform atomization effect ensures comprehensive spray coverage and controllable thickness, making it particularly suitable for scenarios with extremely high coating precision requirements-such as fuel cell membrane electrode coating, solar cell coating, and microelectronic packaging photoresist coating. It can form a dense and uniform coating, significantly improving the product's adhesion, wear resistance, and corrosion resistance, while avoiding common defects in traditional spraying such as uneven thickness, pinholes, and runs. Furthermore, the uniformity of its atomized particles ensures thorough dispersion of liquid components, improving drug absorption efficiency or reaction adequacy in scenarios such as medical nebulization and chemical reaction acceleration.

(II) No clogging, low loss, and significantly reduced maintenance costs

Traditional pressure-type nozzles rely on high pressure to propel liquid atomization. Their small nozzle orifices are easily clogged by impurities and viscous components in the liquid, affecting production continuity and requiring frequent disassembly, cleaning, and nozzle replacement, resulting in high maintenance costs. The 40k ultrasonic atomizing nozzle adopts a "pressureless atomization + high-frequency vibration anti-clogging" design, completely solving this industry pain point. Its nozzle orifice is relatively large, and the high-frequency vibration continuously cleans the channel during atomization, making it less prone to clogging even when handling liquids containing a small amount of solid particles (≤3um) and a viscosity below 500cps. Simultaneously, the nozzle is made of corrosion-resistant titanium alloy with a 316 stainless steel protective shell, eliminating mechanical wear and nozzle wear issues, resulting in a service life far exceeding that of traditional nozzles. Regarding material loss, this nozzle employs a low-speed, gentle spray design, with a spray speed of only 1-3 mm per second, far lower than the 880-1750 mm per second of traditional pressure nozzles. This effectively reduces overspraying, increases material utilization by over 40%, and can save up to 80% of solution in some scenarios, significantly reducing production costs and environmental pollution.

(III) Energy-efficient, highly effective, and controllable, adaptable to diverse production needs

The 40k ultrasonic atomizing nozzle demonstrates significant advantages in energy efficiency and controllability. Unlike traditional high-pressure atomizing equipment that consumes hundreds or thousands of kilowatts of power, this nozzle has an input power of only 1-100W (standard models ≤20W), resulting in extremely low energy consumption. Long-term use can save a significant amount of electricity costs, aligning with the concept of green production. In terms of atomization control, its atomization volume can be precisely adjusted, with a flow rate range from micro-sprays of 2 μl/sec to medium-low atomization rates of tens of milliliters/minute, and an adjustment ratio of up to 10:1. This meets the needs of small-scale powder preparation and micro-coating in laboratories, and is also suitable for large-scale atomization scenarios in industrial production lines. Furthermore, by adjusting the gas flow rate, liquid flow rate, and probe amplitude, precise control of spray width (4-9 cm) and droplet size can be achieved, ensuring process stability and repeatability. In addition, some models are equipped with phase tracking functionality, allowing for real-time frequency adjustment to further improve atomization uniformity, optimize material utilization, and avoid production deviations.

(IV) Wide Range of Applications and Superior Tolerance

The 40k ultrasonic atomizing nozzle has extremely strong adaptability, capable of handling various media such as water, coatings, chemical reagents, lubricating oil, slurries, and even sewage and chemical viscous liquids. There are no media limitations; only simple adjustments based on liquid viscosity (≤500cps) and solid-liquid ratio (≤25%) are required for normal operation. In terms of structural design, this nozzle supports customized modifications and can be designed into various types such as focusing, vortex, and pyrolysis. The focusing type is suitable for small-area precision spraying (such as drug stents and catheter coatings), the vortex type is suitable for coating complex structures such as grooves and vertical surfaces, and the pyrolysis type can operate in high-temperature environments up to 600℃, suitable for scenarios such as metal powder preparation and high-temperature coating preparation. Simultaneously, it can be equipped with a sealing flange to adapt to special environments such as vacuum and pressurization. With a cooling and heating device, it can operate stably in a wide temperature range from -20℃ to 600℃, further expanding its application boundaries and widely covering multiple fields such as new energy, electronics, medical, chemical, agriculture, and environmental protection.

(V) Non-contact atomization, ensuring product and process safety

The 40k ultrasonic atomizing nozzle adopts a non-contact atomization design. After the liquid is atomized by high-frequency vibration, it is delivered to the target surface through a low-speed airflow, without direct contact with the atomized object. This effectively avoids problems such as material splashing and surface scratches, and is especially suitable for handling fragile and precision products-such as microelectronic components, biomedical devices, and fragile glass. In addition, its pressureless atomization feature eliminates the need for a high-pressure air path, and it operates without noise or leakage risk, making it safe and convenient to use. Some medical and food-grade models are made of autoclaved titanium alloy, which meets hygiene standards, avoids material contamination, and ensures product safety and compliance.
