Biodiagnostic Coating
Biodiagnostic Coating – Ultrasonic Spraying Line – Cheersonic
In the ultrasonic spraying line, a solution such as sugar water (density close to 1.0g/mL) is applied to the semi-finished product. The semi-finished product to be coated is a 12x12cm square glass. The coating thickness is about 0.10mm, which can be achieved by adjusting the spraying parameters. The median droplet size is 50 microns, which is generally considered to be fine atomization and suitable for high-precision coating applications.
Here are some suggestions for the spraying process:
Ultrasonic sprayer settings:
Adjust the ultrasonic frequency and power to ensure that the droplet size meets the requirements.
Use the appropriate nozzle and vibration frequency to generate evenly distributed droplets.
Spraying distance:
Adjust the distance from the nozzle to the glass surface to optimize the coating thickness and uniformity. Generally speaking, the farther the distance, the thinner the coating.
Flow rate control:
Control the flow rate of the solution to maintain a stable spray volume, which is critical to the control of coating thickness.
Environmental conditions:
Ensure that the spraying environment is clean and the temperature and humidity are controlled, as these factors can affect the evaporation rate of the droplets and the coating quality.
Coating Process Optimization:
Experiments can be conducted to determine the best coating speed and nozzle movement pattern (e.g., straight or zigzag path).
Consider using multiple passes to achieve the desired coating thickness rather than a single thick coat.
Material Considerations:
Since solutions such as sugar water have densities close to 1.0 g/mL, special attention may need to be paid to viscosity and surface tension to ensure good atomization.
Testing and Monitoring:
Check coating thickness and uniformity regularly, perhaps using a microscope or other surface analysis tools.
Log spray parameters for problem tracking and quality control.
Safety and Maintenance:
Ensure that operators wear appropriate personal protective equipment.
Clean and maintain equipment regularly to maintain optimal spray performance.
With these steps and recommendations, you can optimize your ultrasonic spray process and ensure a high-quality coating product.
