Electromagnetic shielding film is a thin film material used to block electromagnetic radiation, which has ultra-high shielding performance. Electromagnetic radiation is a form of radiation that is ubiquitous in everyday life and can cause potential harm to the human body. Therefore, the development and production of electromagnetic shielding films with good shielding effect are essential to protect human health.
The production process of electromagnetic shielding film is very complex, and it needs to go through multiple processes to ensure product quality and performance. First of all, high-quality, high-purity materials, such as metal films, polymers, etc., need to be selected as raw materials in the production process. These materials are specially treated to form films with high shielding properties.
Secondly, a critical step in the production process is the coating technology. Coating is a key step in which the prepared metal film is evenly coated on the substrate to form an electromagnetic shielding film. By precisely controlling the thickness and uniformity of the coating, the performance of the electromagnetic shielding film can be ensured to be optimal.
In addition, the heat treatment process needs to be considered in the production process. Heat treatment is to treat the substrate coated with a metal film at high temperature to form a tight oxide film on its surface. This oxide film can improve the corrosion resistance of the electromagnetic shielding film and extend the service life of the product.
Finally, the production of electromagnetic shielding films also needs to be tested and inspected. Only through a rigorous testing and inspection process can we ensure that the product meets the requirements and has excellent shielding performance. During the test, it is necessary to use professional instruments and equipment to test the performance of the electromagnetic shielding film, including shielding effect, transmittance and other indicators.
In general, the electromagnetic shielding film with ultra-high shielding performance and its production process is a complex and sophisticated project. Only through strict production process and quality control can we produce high-quality electromagnetic shielding film products to provide protection for people's health and life safety.
