How to avoid coating damage during the use of PI silver plated film?

PI (polyimide) silver plated film is widely used in various fields such as electronics, optics, and medical due to its unique conductivity, reflectivity, and temperature resistance. However, inPI silver plated filmDuring the use, damage to the coating is an issue that cannot be ignored. Coating damage not only affects the performance of PI silver plated film, but may also shorten its service life. Therefore, how to avoid coating damage has become a key technical challenge in the application of PI silver plated film. As a leading enterprise in the research and development of new materials and technologies, Advanced Institute (Shenzhen) Technology Co., Ltd. has achieved significant results in the protection technology of PI silver plated film coating. This article will provide a detailed introduction on how to avoid coating damage during the use of PI silver plated film, and share the relevant technology and experience of Advanced Institute (Shenzhen) Technology Co., Ltd.

Analysis of the causes of coating damage

There are various reasons for coating damage, mainly including mechanical damage, chemical corrosion, high-temperature oxidation, etc. Mechanical damage may be caused by improper operation, friction, scratches, and other factors; Chemical corrosion may be caused by direct contact between corrosive gases, liquids, or solids and the coating; High temperature oxidation is caused by the prolonged exposure of the PI silver plating film to a high temperature environment, where the silver layer reacts with oxygen in the air, resulting in the deterioration of the coating.

Measures to avoid coating damage

1. Thoroughly clean and surface activate treatment

in usePI silver plated filmBefore, it should be ensured that the membrane surface is free of oil stains, dust, and impurities. These pollutants may affect the adhesion between the silver plating layer and the substrate, increasing the risk of coating damage. In addition, surface activation treatments such as plasma treatment or chemical etching can be used to increase the active sites on the surface of the PI film, which is beneficial for the tight bonding between the coating and the substrate, and improves the stability and oxidation resistance of the coating.

2. Environmental control and protection

In the usage environment, corrosive gases such as hydrogen sulfide, sulfur dioxide, etc. should be avoided, as these gases can have adverse effects on the coating, accelerate the corrosion and damage of the coating. At the same time, the PI silver plated film should be stored in a dry, ventilated, and sun free place to avoid moisture and high temperature environments that accelerate the oxidation of the silver layer. During storage and transportation, professional packaging materials (such as foam plastic, bubble film, etc.) should be used to package PI silver coating film to prevent friction and scratches during storage.

3. Control operations and avoid mechanical damage

During the operation, it is necessary to avoid mechanical scratches, wear, and other damage to the PI silver plated film. You can use professional operating tools and ensure gentle operation techniques. At the same time, regularly clean the PI silver plated film to remove surface stains and impurities, and maintain the cleanliness of the coating. Once discoveredPI silver plated filmSurface damage or defects should be repaired or replaced in a timely manner to prevent further expansion of the damage.

4. Select high-quality materials and processes

Select PI film with high chemical corrosion resistance and stability as the substrate, and adopt advanced silver plating technology (such as pulse electroplating) to improve the density and uniformity of the silver plating layer, thereby reducing pores and defects and enhancing oxidation resistance. In addition, it is also possible to consider adding a protective layer or performing post-treatment on the silver plating layer, such as passivation or sealing treatment, to further improve the corrosion resistance and adhesion of the coating.
