Coated electromagnetic shielding glassIt is a new type of glass material characterized by coating an electromagnetic shielding film on the surface of the glass, which can effectively isolate the interference of electromagnetic waves. This article will introduce the principle, manufacturing process, and application of coated electromagnetic shielding glass.
1、 The principle of coated electromagnetic shielding glass
The principle of coated electromagnetic shielding glass is to coat a layer on the surface of the glass
Electromagnetic shielding filmForm a semiconductor layer with shielding function on the surface of the glass. This semiconductor layer can resist the interference of electromagnetic waves and play a shielding role.
2、 Manufacturing process of coated electromagnetic shielding glass
The production of coated electromagnetic shielding glass mainly involves the following steps:
1. Cleaning of substrate glass: Use a specific cleaning solution to clean the surface of the glass to remove oil stains and impurities, ensuring that subsequent processes can proceed normally.
2. Coating preparation: Disperse the material used for coating in a solvent to prepare a film-forming solution. Place the pre treated glass in a vacuum device and apply coating under vacuum conditions.
3. Coating layer control: Adjust the process parameters of the coating equipment, such as deposition time, pressure, temperature, flow rate and type of reaction gas, to control the thickness and uniformity of the coating. After a certain period of time, a layer of electromagnetic shielding film is generated on the surface of the glass.
4. Baking treatment: Send the coated glass into the baking equipment for heating treatment. Only within a certain temperature range can the performance of electromagnetic shielding glass reach its optimum. After baking treatment, the glass can achieve the best shielding effect.
