introduction

As a new functional material, fluorescent film has a wide range of application prospects in LED lighting, displays, sensors and other fields. However, in the preparation of fluorescent films, the flatness of the substrate is critical to the coating effect. In order to solve the problem that soft substrates are prone to wrinkles during the coating process, vacuum adsorption coating technology was introduced, which is used to fix the substrate on the table surface and ensure that the substrate is flat, so as to achieve precise control of the coating process and high-quality production. In this article, we will introduce in detail the application and advantages of vacuum adsorption coating technology in the preparation of fluorescent films.

Principles of vacuum adsorption coating technology

Vacuum adsorption coating technology is a coating method that uses the adsorption force in a vacuum environment to fix a soft substrate on a countertop. The principle is that by placing the substrate in a vacuum chamber and establishing a vacuum adsorption force on the countertop, the substrate is tightly adhered to the countertop, avoiding wrinkles in the substrate during the coating process. This ensures the flatness and stability of the substrate during the coating process, resulting in a high-quality preparation of the coated film.

The process of preparing fluorescent diaphragms

The process of preparing fluorescent diaphragms includes substrate preparation, coating process, drying process and other steps.

1) Substrate preparation

Choose a soft substrate, such as polymer film or paper, and make sure it has a flat surface that is suitable for vacuum adsorption and fixation on the countertop.

2) Coating process

The substrate is placed in a vacuum chamber and the vacuum adsorption device is activated to fix it on the table top. Then, the fluorescent material is applied to the surface of the substrate, and the vacuum adsorption force is used to ensure the flatness of the substrate during the coating process and avoid the formation of wrinkles.

3) Drying process

The coated fluorescent film is dried to remove residual solvent and moisture, and the stability and weather resistance of the film are improved.

Application areas and advantages

Vacuum adsorption coating technology has obvious advantages in the preparation of fluorescent diaphragms. First of all, by fixing the substrate on the table, the wrinkles of the substrate during the coating process are avoided, and the flatness and stability of the coating film are ensured. Secondly, this technology can achieve precise control of the coating process and ensure the thickness and uniformity of the coating film. Therefore, in the fields of LED lighting, displays, etc., vacuum adsorption coating technology is often used in the preparation of fluorescent diaphragms to ensure product quality and performance.

Challenges and prospects

Although vacuum adsorption coating technology has obvious advantages in the preparation of fluorescent films, there are still some challenges, such as the optimization of coating process parameters, the selection of coating materials, and the treatment of substrates. In the future, we will further improve the technology, improve the quality and stability of the coating film, expand the application of fluorescent film in various fields, and provide more possibilities for the research and application of functional materials.

conclusion

Vacuum adsorption coating technology plays an important role in the preparation of fluorescent films, by fixing the substrate on the table to avoid wrinkles affecting the coating effect, so as to achieve precise control of the coating process and high-quality production. With the continuous advancement of technology, vacuum adsorption coating technology will play an increasingly important role in the preparation of functional materials, providing more possibilities for applications in various fields.
