Production Type Ultrasonic Spraying System 15.6-inch Hhigh-Definition Touch Screen with Large Area Film Production

Description:

Ultrasonic spray is a unique spray technology, which is based on ultrasonic spray nozzle technology. The material sprayed is first in a liquid state, which can be a solution, sol, suspension, etc. The liquid coating is first atomized into fine particles through an ultrasonic atomization device, and then uniformly coated on the surface of the substrate with a certain amount of current carrying gas, forming a coating or thin film. Compared to traditional pneumatic two fluid spraying, ultrasonic atomization spraying can achieve better uniformity, thinner coating thickness, and higher accuracy. Meanwhile, due to the fact that ultrasonic nozzles do not require air pressure assistance to atomize, the use of ultrasonic spraying can significantly reduce paint splashing during the spraying process, achieving the goal of saving paint. The paint utilization rate of ultrasonic spraying is more than four times that of traditional two fluid spraying.

The principle of ultrasonic atomization spraying:

Ultrasonic nozzles use the piezoelectric effect to convert electrical energy into high-frequency mechanical energy, which is transferred to the liquid and generates standing waves. The liquid is introduced into the atomization surface through the nozzle. When the liquid leaves the atomization surface of the nozzle, it is broken into uniform micrometer sized fine mist droplets, thereby achieving atomization. In the ultrasonic spraying process, the size and distribution of droplets can be precisely controlled, allowing very small droplets and particles to evaporate quickly, resulting in particles with high specific surface area and forming a thin film coating.

Parameters:

General configuration:

1. Viscosity and solid content: Typically, viscosity ≤ 30cps, and suspension requires a solid content not exceeding 20-30%
2. Liquid supply equipment: precision injection pump+biological grade sampler, with a liquid supply accuracy of 0.1uL/min
3. Dry film thickness: 20nm-100um (related to the substrate of the solution)
4. Input voltage: 220V ± 10%, 50-60Hz
5. Solution conversion rate: ≥ 95%, utilization rate several times that of traditional two fluid pneumatic nozzles
6. Atomized particle size: average 15-45 μ m. It mainly depends on the frequency of the nozzle, and the higher the frequency, the smaller the particle size
7. Spray nozzle frequency: can be equipped with various spray nozzle systems ranging from 30-200KHz

Optional configuration:

1. Ultrasonic dispersion liquid supply system: It can continuously disperse and stir nanoparticles during the spraying process, effectively reducing the precipitation phenomenon of the spraying liquid and greatly improving the uniformity of the film layer
2. Heating and drying platform: using aviation aluminum porous platform or precision micro porous ceramic platform, with precise temperature control of 200 ℃
3. Vacuum adsorption platform: equipped with a multi-channel vacuum generator that can be controlled by zones, accurately adsorbing the thin film substrate without deformation.
4. Spray nozzle alignment device: Laser alignment is used.
5. We can also customize other configurations that you need!
