Cover Glass Coating Preparation
Cover glass coating preparation is a process involving multiple steps and processes, among which ultrasonic spraying technology is widely used in the preparation of cover glass coating due to its unique advantages. The following is a detailed description of the cover glass coating preparation process, especially the application of ultrasonic spraying technology:
1. Cover glass preparation
- Cutting and cleaning:
First, cut the glass into cover glass of the required size, usually square or rectangular, about 20 mm wide and a few millimeters thick.
After cutting, use an ultrasonic cleaner to clean the cover glass to remove dust, oil and other impurities on the surface to ensure that the coating can be firmly attached to the surface of the cover glass.
2. Coating solution preparation
- Solution configuration:
According to the properties and functions of the required coating, configure the corresponding coating solution. The composition and concentration of the solution need to be adjusted according to specific needs.
For coatings that require specific functions (such as anti-fouling, anti-fingerprint, enhanced optical performance, etc.), the corresponding functional materials need to be selected and added to the solution.
- Ultrasonic atomization:
The coating solution is injected into the ultrasonic sprayer, and the solution is atomized into tiny particles by ultrasonic vibration. The effect of ultrasonic vibration makes the distribution of coating particles more uniform, which is conducive to the formation of high-quality coatings. - Uniform spraying:
The atomized coating particles are evenly sprayed on the surface of the cover glass through a spray gun. During the spraying process, the spraying parameters (such as ultrasonic frequency, amplitude, spraying speed, pressure, distance, etc.) can be adjusted as needed to control the thickness and uniformity of the coating.
4. Drying and curing
- Drying treatment:
After spraying, the cover glass is placed under appropriate conditions for drying to remove the solvent and moisture in the coating and make the coating initially cured. - Curing treatment:
According to the properties and requirements of the coating, further curing treatment is carried out. The method and time of curing treatment need to be adjusted according to the specific coating to ensure that the coating achieves the required hardness and performance.
5. Quality inspection
- Appearance inspection:
The prepared cover glass coating is inspected to ensure that the coating surface is flat, without scratches, bubbles and other defects. - Performance test:
Perform performance tests such as optical properties, wear resistance, corrosion resistance, etc. are carried out according to the function and purpose of the coating to evaluate whether the quality and performance of the coating meet the requirements.
6. Advantages of Ultrasonic Spraying Technology
- High coating uniformity:
Ultrasonic spraying technology can achieve uniform distribution of coating particles, thereby preparing highly uniform coatings. - High production efficiency:
Ultrasonic spraying technology can achieve efficient spraying operations and improve production efficiency. - High raw material utilization rate:
The coating utilization rate is high during ultrasonic spraying, reducing coating waste and cost. - Strong environmental protection:
No harmful substances such as organic solvents are required during ultrasonic spraying, reducing environmental pollution.
In summary, the preparation of cover glass coating is a delicate and complex process, and ultrasonic spraying technology plays an important role in the preparation of cover glass coating due to its unique advantages. Through precise process control and optimized parameter settings, high-quality and high-performance cover glass coatings can be prepared to meet the needs of different fields.
