Ultrasonic Spraying Machine for FTO Coating

Ultrasonic Spraying Machine for FTO Coating – Cheersonic

FTO coating has become an indispensable key material in high-end manufacturing fields such as new energy and display panels due to its excellent transparent conductivity and weather resistance. This coating with fluorine doped tin oxide as the core component needs to ensure high visible light transmittance and stable conductivity. The precision of its preparation process directly determines the product performance. Ultrasonic spraying equipment, with its unique atomization principle, has established an efficient and high-quality technical support system in the preparation of FTO coatings, breaking through many bottlenecks of traditional processes.

When traditional spray coating technology is used to prepare FTO coatings, it often faces problems such as uneven particle distribution, low precision in film thickness control, and serious material waste. The core advantage of ultrasonic spraying equipment lies in its high-frequency vibration atomization mechanism. The equipment converts electrical energy into high-frequency mechanical vibration through ultrasonic transducers, allowing FTO slurry to be atomized into tiny droplets with a diameter of only a few micrometers under no or low pressure conditions. These uniform and delicate droplets can be precisely deposited on the surface of the substrate under the guidance of airflow, forming a dense and uniformly thick coating, effectively avoiding common defects such as pinholes and sagging in traditional processes.

In terms of process control, ultrasonic spraying equipment exhibits strong adaptability. The performance of FTO coating requires extremely high precision in film thickness. Excessive thickness will reduce light transmittance, while excessive thickness will lead to insufficient conductivity. The equipment can control the film thickness error within the nanometer range by adjusting parameters such as ultrasonic frequency, slurry supply speed, and nozzle movement trajectory, to meet the coating index requirements in different scenarios. Meanwhile, its low-temperature atomization characteristics prevent the thermal decomposition of active ingredients in the slurry, making it particularly suitable for spraying on temperature sensitive substrates such as flexible substrates, and expanding the application scenarios of FTO coatings.

The improvement of material utilization rate is another highlight of ultrasonic spraying equipment. The utilization rate of traditional spraying materials is usually less than 50%, and a large amount of FTO slurry is wasted due to uneven atomization. The directional deposition ability of ultrasonic spraying increases the material utilization rate to over 85%, which not only reduces production costs but also reduces waste liquid emissions, in line with the development trend of green manufacturing. In large-scale production, this advantage can significantly reduce the raw material costs of enterprises and enhance the market competitiveness of products.

From the perspective of application effect, the FTO coating prepared by ultrasonic spraying equipment has a visible light transmittance of more than 90%, and a block resistance of less than 10 ohms. At the same time, it has excellent acid and alkali corrosion resistance and anti-aging performance, fully meeting the long-term use needs of photovoltaic modules, touch screens, smart windows and other products. With the upgrading of the high-end manufacturing industry, the application areas of FTO coatings continue to expand. Ultrasonic spraying equipment, with its comprehensive advantages in accuracy, efficiency, environmental protection, etc., is becoming the core equipment to promote the iteration of FTO coating technology, injecting sustained momentum into the high-quality development of related industries.
