50Khz Ultrasound Wide Type Spray Coating Nozzles for Large Area
Glass Coated
Description:
The wide ultrasonic atomization nozzle is combined with a
controlled jet from a planar jet guide plate. The atomized spray is
immediately entrained in the airflow on the atomized surface of the
nozzle, forming a fan-shaped spray style. The speed of air flow is
controllable, thus allowing low or high impact of atomized spray on
products or substrates. This multifunctional air forming system can
spray patterns up to 6 inches (15 centimeters), depending on the
distance from the substrate. In wide area applications where
multiple nozzles are used in series, the width is not limited.
The wide range ultrasonic nozzle has a larger spraying width and is
mainly suitable for various medium and large area spraying
applications. It can be used for various applications including
float glass spraying, textile spraying, fuel cell spraying, proton
exchange membrane spraying, fuel cell spraying, membrane electrode
spraying, metal plastic sheets, AR anti reflective film spraying,
insulation film spraying, superhydrophobic coating spraying, and
flux spraying.

The working frequency and amplitude of ultrasonic spraying machines
are important factors affecting nozzle selection. They directly
affect the coating dispersion and spraying effect of ultrasonic
spraying machines. The following are their impacts on nozzle
selection:
1. Working frequency: The working frequency of an ultrasonic
spraying machine refers to the frequency of ultrasonic vibration,
usually measured in kHz. The working frequency can affect the
selection of nozzles, especially the aperture size of the nozzle. A
higher operating frequency means a higher vibration frequency, and
the residence time of coating particles in the nozzle aperture is
shorter, so a smaller nozzle aperture is usually required. On the
contrary, lower operating frequencies require larger pore sizes to
accommodate coating particles.
2. Amplitude: Amplitude refers to the vibration amplitude generated
by an ultrasonic spraying machine, usually measured in micrometers.
The amplitude will affect the dispersion effect of the coating. A
larger amplitude can better disperse the coating into small
particles, so a smaller nozzle aperture can be used. A smaller
amplitude may require a larger nozzle aperture to ensure that the
coating can pass smoothly through the nozzle.
When selecting a nozzle, it is necessary to match the working
frequency and amplitude with the viscosity, particle size, and
spraying requirements of the coating. High frequency and large
amplitude are usually suitable for smaller particle size coatings
and fine spraying requirements, while low frequency and small
amplitude are suitable for larger particle size coatings and
large-area spraying.
It should be noted that the working frequency and amplitude of
ultrasonic spraying machines are determined by equipment design and
manufacturing, and are usually determined when purchasing the
equipment. Therefore, when selecting a nozzle, it is necessary to
choose it based on the operating frequency and amplitude range of
the equipment to ensure the compatibility between the nozzle and
the equipment.
