25Khz Special Cutomized Gathering Ultrasonic Focusmist Spray Nozzle for High Solid Content Slurry
Description:
The convergent ultrasonic atomization nozzle is combined with low-pressure air/gas to produce a soft, highly focused small droplet beam. Usually, compressed air/gas of 1 psi is introduced into the diffusion chamber of the air guide hood surrounding the nozzle, generating a uniformly distributed air/gas flow around the nozzle rod. The spray generated by the ultrasonic wave at the tip of the valve stem is immediately entrained in the low-pressure air/airflow. The adjustable focusing mechanism on the wind deflector can fully control the spray width. The spray hood is very narrow and shaped like an hourglass. The width of the shape is controlled by adjusting the distance between the nozzle and the substrate, ranging from 0.07-1.0 inches (1.78-25 mm). Very suitable for small devices such as brackets, balloon conduits, wires, flux for selective welding applications, etc.

Choosing appropriate parameters and process conditions for ultrasonic spraying machines requires consideration of the viscosity range of the coating to ensure spraying effectiveness and process stability. Here are some suggestions:
1. Working frequency: Choose an appropriate working frequency based on the viscosity range of the coating. Coatings with lower viscosity are usually suitable for higher operating frequencies, while coatings with higher viscosity are suitable for lower operating frequencies. Based on experience, low viscosity coatings are generally suitable for working in the frequency range of 20 kHz to 100 kHz, while high viscosity coatings are suitable for working in the frequency range of 10 kHz to 30 kHz. But the specific frequency selection should also be tested and optimized in conjunction with the actual situation.
2. Amplitude: The selection of amplitude should be adjusted according to the viscosity range of the coating. High viscosity coatings typically require larger amplitudes, while low viscosity coatings typically require smaller amplitudes. Based on experience, the amplitude can be within 10 μ M to 100 μ Adjust between m. The specific amplitude selection should also be tested and optimized based on the actual situation.
3. nozzle size and shape: The viscosity of the coating can also affect the choice of nozzle. Lower viscosity coatings are usually suitable for using smaller nozzles, while higher viscosity coatings are usually suitable for using larger nozzles. The shape of the nozzle (such as conical, flat, etc.) can also be selected based on the viscosity of the coating and spraying requirements.
4. Spray speed and distance: The viscosity of the coating can also affect the selection of spray speed and spray distance. Coatings with higher viscosity typically require slower spraying speeds and closer spraying distances to ensure uniform spraying and coverage of the coating.
5. Temperature control: Some coatings exhibit significant changes in viscosity at different temperatures. Therefore, according to the viscosity range of the coating, it may be necessary to control the temperature of the ultrasonic spraying machine to maintain the coating within the appropriate viscosity range.
Please note that different ultrasonic spraying machines may have different parameters and adjustment ranges. When selecting parameters and process conditions, it is recommended to refer to the equipment's operating manual and manufacturer's guidance for testing and optimization to achieve the best spraying effect and process stability.
