Application of Ultrasonic Spray Coating Technology in Float Glass Anti-corrosion Coatings

Float glass is a widely used glass product in various fields. Its production process involves floating molten glass on a high-temperature tin bath to form a flat, smooth, and uniform glass ribbon. Float glass has advantages such as good optical properties, high transparency, and high surface quality. However, it also has some disadvantages, including susceptibility to corrosion and stains from humid environments and pollutants. To enhance the corrosion resistance and aesthetics of float glass, it is common to apply an anti-corrosion coating on its surface.

There are various types of anti-corrosion coatings, including powder coating, pressure spraying, sol-gel method, chemical vapor deposition (CVD), among others. These methods have their own advantages and disadvantages but also share common issues such as uneven coating, material wastage, complex equipment, and high energy consumption. In order to address these problems, ultrasonic spray coating technology has gained increasing attention and application as a novel coating method.

Ultrasonic spray coating technology utilizes ultrasonic vibration to atomize liquid into fine droplets, which are then uniformly deposited onto the glass surface through compressed air, forming a coating.

Ultrasonic spray coating technology offers several advantages compared to other methods:

Uniform coating: The uniform and controllable droplet size generated by ultrasonic atomization ensures consistency in coating thickness and density.

High material utilization: The low velocity and controllable direction of the atomized droplets reduce material diffusion and deposition in the air, improving the coverage on the glass surface.

Simple equipment: Ultrasonic atomization does not require heating or pressurizing the liquid, reducing equipment complexity and costs.

Low energy consumption: Ultrasonic atomization requires minimal electrical and gas energy, resulting in energy savings and reduced environmental pollution.

Ultrasonic spray coating technology has been successfully applied in anti-corrosion coatings for float glass. Specialized systems for anti-corrosion coatings on float glass can perform online spraying of water-soluble organic acid solutions (such as maleic acid, maleic anhydride, adipic acid, etc.) to protect the glass surface from corrosion and stains caused by humid environments and pollutants during transportation and storage.

The system features:

Online corrosion protection: Suitable for high humidity environments, effectively protecting the glass surface.

No clogging: Ultrasonic atomization does not produce solid particles, avoiding nozzle clogging.

High conversion efficiency: Direct deposition of droplets generated by ultrasonic atomization minimizes material loss.

Environmentally friendly: Ultrasonic atomization does not require high temperature or pressure, reducing emissions and noise.

High reliability: Ultrasonic atomization provides automatic adjustment and control, ensuring coating stability and consistency.

High flexibility: Ultrasonic atomization can utilize various coating materials to provide different coating effects according to customer requirements.

In conclusion, ultrasonic spray coating technology is a novel method for anti-corrosion coatings on float glass, offering advantages such as uniform coating, high material utilization, simple equipment, and low energy consumption. It has been widely applied and recognized in the field of float glass anti-corrosion coatings. With continuous development and improvement, ultrasonic spray coating technology will contribute to providing float glass with enhanced functionality and value.

Here are some successful case examples of ultrasonic spray coating technology in corrosion-resistant coatings for float glass:

1. A glass manufacturing company in Germany successfully developed an efficient corrosion-resistant coating for float glass using ultrasonic spray coating technology. They utilized an ultrasonic spray coating system to uniformly apply a water-soluble organic acid solution onto the glass surface, forming a corrosion-resistant coating. This coating effectively protects the glass from corrosion and damage caused by humid environments and pollutants, thereby improving the durability and reliability of float glass.

2. A glass manufacturing company in Japan successfully developed a high-transparency corrosion-resistant coating using ultrasonic spray coating technology. They employed an ultrasonic spray coating system to uniformly apply a corrosion-resistant sol-gel material onto the surface of float glass, forming a uniform and transparent coating. This coating exhibits excellent corrosion resistance without compromising the optical transparency of the glass, allowing float glass to maintain clear visual effects even in humid environments.

3. A technology company in the United States successfully researched and developed a self-cleaning coating for float glass using ultrasonic spray coating technology. They utilized an ultrasonic spray coating system to uniformly apply a self-cleaning nano-coating onto the glass surface. This coating possesses anti-pollution and easy-to-clean properties, automatically degrading dirt and pollutants, thereby reducing the frequency and effort required for glass cleaning. It enhances the maintenance efficiency and lifespan of float glass.

These case examples demonstrate the successful application of ultrasonic spray coating technology in corrosion-resistant coatings for float glass. Through ultrasonic spray coating technology, the uniformity, transparency, and functionality of coatings can be improved, offering greater possibilities for the performance and applications of float glass.
