Precision Ultrasonic Atomizing Spraying Equipment for PTFE, Adhesive, Nano Coating

 
What is the ultrasonic spray nozzle?
An ultrasonic spray nozzle is a device that uses high-frequency vibrations to atomize a liquid into a fine mist or spray. It is designed to generate ultrasonic waves, typically in the range of 20 kHz to 120 kHz, which are transmitted to the liquid being sprayed. These ultrasonic waves create high-velocity pressure waves in the liquid, causing it to break up into tiny droplets.
The ultrasonic spray nozzle consists of several key components. It typically includes a transducer, which is responsible for generating the ultrasonic waves. The transducer is usually made of piezoelectric materials that convert electrical energy into mechanical vibrations. The vibrations are then transferred to a horn or a nozzle tip.
The horn or nozzle tip amplifies the ultrasonic vibrations and focuses them on the liquid. This amplification helps in generating higher velocities and pressures, leading to more efficient atomization. The liquid is supplied to the nozzle, and the ultrasonic vibrations cause it to break up into a fine mist or spray, which can be directed onto a target surface.

Ultrasonic spraying system
The ultrasonic spraying equipment has self-cleaning, which can avoid pollution of the inner wall of the blood collection tube during the spraying process, and can also avoid the contamination of its own nozzle, and can be sprayed and used in cycles. The ultrasonic spraying system can program the number, distance, thickness and other parameters of spraying, so as to ensure the accuracy of the spraying effect. Ultrasonic spraying equipment can save raw materials, and the utilization rate of raw materials is as high as 85%. Industrial ultrasonic atomizers can be easily retrofitted into existing production lines for efficient spraying with consistent quality output.

As an industrially proven technology, ultrasonic spraying has been successfully applied to high-performance thin film coating lines in the manufacturing of precision electronics such as semiconductors, precision devices, nanotechnology applications, fuel cells and solar cells. During ultrasonic spraying, the size and distribution of droplets can be precisely controlled, resulting in particles with a high surface area.
