The Advantages of Ultrasonic Spraying Nano Coating

The Advantages of Ultrasonic Spraying Nano Coating – Cheersonic

Ultrasonic spraying, as an advanced precision coating technology, has demonstrated multiple core advantages in the preparation of nano coatings, including high precision, excellent quality, and low cost, based on the principle of high-frequency vibration atomization. It has become the preferred process for the preparation of nano functional coatings in fields such as new energy, electronic semiconductors, and healthcare.

The coating accuracy is extremely controllable, and the uniformity is excellent
Ultrasonic spraying utilizes 20-120kHz high-frequency vibration to atomize the coating into uniform droplets of 1-50 microns, with narrow particle size distribution and no high-pressure splashing. It can achieve precise control of coating thickness from nanometer to micrometer level, with a stable error range of ± 2%. Compared to traditional spraying with an error of ± 10%, this technology eliminates defects such as orange peel lines, sagging, and pinholes from the root, resulting in a dense and continuous coating with a uniformity of over 95%. This high-precision feature is suitable for high flatness demand scenarios such as optical films, perovskite photovoltaics, and chip thermal conductive layers, ensuring stable product performance.

The material utilization rate has significantly increased, resulting in significant cost reduction and efficiency improvement
Traditional pressure spraying has a high overspray rate and severe material loss, while ultrasonic spraying has no high-pressure impact and strong fog titration directionality. The material utilization rate can reach 90% -95%, which is more than four times that of traditional processes. Especially suitable for high-value materials such as precious metal catalysts, nano slurries, and fluorine-containing anti fingerprint coatings, it can significantly reduce losses, minimize waste liquid emissions, and align with the concept of green production. At the same time, this process does not require a high vacuum environment and can be operated under normal pressure. The equipment cost is much lower than vacuum evaporation, sputtering and other processes, and the process flow is short, making it easy to achieve large-scale continuous production.

Wide substrate adaptability and non-destructive coating
Ultrasonic spraying belongs to the “soft spray” process. The initial velocity of the droplets is low, and there is no mechanical impact. It can be adapted to hard substrates such as glass and metal, and can also handle fragile substrates such as flexible plastics, films, medical catheters, and there is no risk of damage. Mist droplets can effectively wrap around three-dimensional structures, achieving uniform coverage on curved, irregular, and porous substrate surfaces, breaking through the limitations of traditional processes on substrate shape. In addition, this technology is compatible with various coating systems such as water-based and organic solvent based coatings, and can stably atomize high viscosity, solid particle containing nano slurries with diverse application scenarios.

Excellent coating performance and outstanding functional effects
The ultrasonic atomization process can effectively disperse and agglomerate nanomaterials, resulting in uniform dispersion of particles such as graphene and carbon nanotubes, forming a continuous and dense functional network. The prepared coating has significantly improved performance in terms of conductivity, thermal conductivity, corrosion resistance, and hydrophobicity. For example, the carbon nanotube coating has a uniform conductive network and a 40% increase in current carrying capacity; Graphene heat dissipation coating improves heat dissipation efficiency by 35%; MXenes anti-corrosion coating can extend the corrosion resistance time of metals by more than twice. In fields such as fuel cells and lithium batteries, this technology can increase catalyst utilization by more than 30% and enhance electrode conductivity and stability.

In summary, ultrasonic spray nano coating technology, with its core advantages of high precision, high utilization, strong adaptability, and excellent performance, solves the pain points of traditional processes, helps upgrade nano coating technology in high-end manufacturing fields, and has broad application prospects and economic value.
