Plastic plating is a method of imparting a metallic appearance and performance to a plastic substrate by depositing a metallic coating on it. Roughening is a key step in the plastic plating process and is critical to the quality of the final coating. However, inadequate roughening can cause a number of problems that affect the performance and appearance of the final product. In this article, we explore the effects of insufficient roughening.
Roughening is the physical or chemical creation of microscopic roughness on a plastic surface to enhance the adhesion of subsequent plating. Insufficient roughening results in a weakened bond between the plating and the plastic substrate. This incomplete bonding directly affects the adhesion of the plating, which may lead to defects such as peeling and blistering of the plating during use, seriously affecting the durability and aesthetics of the product.
Specifically, insufficient coarsening can lead to several major problems:
1. Insufficient adhesion: the plating layer is easy to peel off from the plastic surface, affecting the service life of the product. Poor adhesion may be particularly evident when subjected to mechanical stress, thermal stress or chemical corrosion.
2. Surface defects: The uniformity of the plating layer is negatively affected by the appearance of localized thin films, pinholes or blistering and other defects. These defects not only affect the appearance, but may also lead to increased galvanic corrosion and reduced protective performance.
3. Mechanical properties decline: due to the combination of the plating and the substrate is not strong, so that the plating can not be a good transfer of stress, resulting in the plating in the stress of fracture or peeling.
Through the above analysis, we can find that insufficient roughening of plastic plating will seriously affect the adhesion, appearance and mechanical properties of the plated layer. Through the use of Bigely roughing additives and strict control of process parameters, it is possible to rough plastic workpieces in place, improve the quality of plating and ensure the performance and service life of plated products.
