Have You Used The Widemist 30khz Ultrasonic Spray Nozzle?

In the field of slurry atomization spraying, uniformity, efficiency, and material utilization have always been the core pursuits of the industry. Traditional spraying technologies often struggle to balance the contradictions between adapting to high-viscosity slurries, large-area spraying, and coating quality. RPS-SONIC's newly launched 30kHz wide-spray nozzle, RPS-AT30, relies on 30kHz low-frequency ultrasonic core technology to precisely adapt to various high-viscosity, high-solids-content systems in the slurry industry. Its wide-spray design breaks through the limitations of traditional nozzle spraying, redefining the standards of high efficiency and precision in slurry atomization spraying.

30kHz low-frequency ultrasonic atomization spraying uses mechanical vibration as its core power source. The generator outputs a 30kHz electrical signal, which is transmitted to a piezoelectric transducer. The transducer efficiently converts the electrical energy into micron-level high-frequency mechanical vibration. After amplification by an amplitude transformer, the vibrational energy is precisely transmitted to the tip of the RPS-AT30 nozzle. When the slurry flows through the nozzle, the high-frequency vibration breaks down the intermolecular forces, "shattering" it into uniform micron-sized droplets. These droplets have extremely low initial velocities and require only a small amount of carrier gas (air or nitrogen) to guide them as they gently settle onto the substrate surface, forming a dense and uniform coating. This achieves simultaneous atomization and deposition, balancing efficiency and quality.

The core advantage of 30kHz low-frequency technology lies in its adaptability to high-viscosity slurries. The low-frequency vibration provides stronger mechanical force, effectively breaking up agglomerated particles in the slurry while ensuring sufficient atomization, thus balancing droplet uniformity and spraying efficiency. Furthermore, low-frequency ultrasonic atomization spraying eliminates the need for high-pressure nozzles, fundamentally avoiding the nozzle clogging problems common in traditional spraying. This significantly reduces equipment maintenance costs and minimizes slurry waste, increasing material utilization to over 90%, aligning with the industry's trend towards green production and cost reduction.

As RPS-SONIC's latest masterpiece for the slurry industry, the RPS-AT30 30k atomizing wide-spray nozzle, while inheriting the core advantages of 30kHz low-frequency ultrasonic atomization, has undergone targeted structural optimization and functional upgrades, perfectly adapting to the large-area, high-requirement spraying scenarios in the slurry industry. Compared to ordinary 30kHz nozzles, the biggest highlight of the RPS-AT30 is its wide-spray design. Utilizing RPS-SONIC's proprietary wide-dispersion probe technology, it precisely expands the spray width, breaking the limitations of traditional nozzles that have narrow spray areas and require repeated back-and-forth spraying. This significantly improves spraying efficiency, making it particularly suitable for slurry spraying scenarios such as photovoltaic backsheets, glass coating, and large-area panel corrosion protection. It reduces spraying time and avoids problems such as uneven coating thickness and edge stacking caused by repeated spraying, ensuring consistency across the entire sprayed surface.

Considering the actual spraying needs of the slurry industry, the RPS-AT30, with its core advantage of 30kHz low-frequency atomization combined with its wide-spray design, can flexibly adapt to the slurry spraying requirements of different fields. It can precisely adjust the power, liquid supply flow rate, and carrier gas flow rate according to the slurry viscosity, solid content, and target film thickness, achieving precise control of film thickness, good repeatability, and significantly improving product yield.

In addition, the heat generated by low-frequency vibration is concentrated and gentle, which will not cause the heat-sensitive components in the slurry to deteriorate, nor will it cause large-area scorching. It is especially suitable for high-end slurry spraying containing nanoparticles and heat-sensitive additives, taking into account both coating quality and material performance.
