15W 100kHz High-Frequency Ultrasonic Nano Coating Spray Nozzle

This spray unit integrates ultrasonic spraying technology with air jet aeration. It generates a fan-shaped spray coverage reaching 120 mm, supports multi-nozzle parallel operation, and suits large-area coating applications.

Airflow velocity and atomized droplet size of this large ultrasonic nozzle system can be precisely tuned to match diverse workpiece and substrate specifications. Constructed from titanium and stainless steel, the equipment delivers broad liquid compatibility. It accepts ultrasonic nozzles across multiple frequency options: 50kHz, 60kHz, 100kHz and 120kHz.

The 15W 100kHz high-frequency ultrasonic nano coating spray nozzle is engineered to prevent glass surface corrosion and contamination. In most cases, a uniform anti-fouling coating layer needs to be applied onto glass substrates. Typical coating fluids include aqueous organic acid solutions, such as malic acid, maleic acid and adipic acid.

Ultrasonic spraying finds wide adoption in glass production, covering float glass, functional coatings and protective coating processes.

 

 

 

A wide range of coatings, chemical reagents, lubricants and particle suspensions can be atomized smoothly. Still, properties including viscosity, miscibility and solid content must be taken into account. For optimal atomization performance, keep liquid viscosity under 30 cps and solid concentration below 8%.

 

Ultrasonic atomization spraying works based on liquid film vibration. Higher liquid viscosity makes atomization harder to achieve. Liquids with long-chain polymer molecules feature strong cohesive forces; even after dilution, they remain difficult to atomize. In general, suspensions with monodisperse single particles atomize more readily.

 

1. Plain pure liquids

This category covers single-component neat liquids (water, alcohol, bromine, etc.) and true solutions (brine, polymer solutions, etc.), plus mixtures with undissolved solids such as coal slurry, polymer bead-water mixtures, silica-alcohol suspensions and similar slurries.

 

For pure liquids, viscosity is the sole parameter governing atomization quality, with a typical upper viscosity limit near 10 cp.

 

2. Polymer-containing solutions

Pure solutions behave much like neat liquids in most scenarios. The exception occurs when the solution contains long polymer molecular chains. Polymer chain length directly impacts the atomization process. As droplets detach from the bulk liquid to form atomized mist, these long polymer chains obstruct the separation of discrete droplets.

 

3. Mixtures with undissolved solid particles

Three key parameters control atomization performance for solid-laden suspensions: particle size, solid loading, and dynamic interaction between solid particles and the liquid carrier.

 

Solid particle concentration is critical, with a practical upper limit around 15%. Atomization at high solid loading requires carefully adjusted operating conditions. Even with suitable particle sizes, other dynamic properties still determine whether successful atomization can be achieved, such as carrier viscosity and the suspension stability of solid materials.

 

If particle size exceeds one-tenth of the median droplet size, the mixture typically atomizes easily. When solid particles are encapsulated inside droplets, the final droplet size must be substantially larger than the solid particles. Otherwise, most generated droplets will not carry solid particles, leading to phase separation.
