During steel processing, transportation and storage, the surfaces of steel parts are often contaminated with a variety of oils. These oils not only affect the appearance of steel parts, but also may have a negative impact on subsequent processing and use. Therefore, it is important to understand the types of oil and grease on the surface of steel parts and which steel chemical degreasing powder to use.
In the plating process, zinc-nickel alloy is favored for its good corrosion resistance and mechanical properties. However, in order to ensure the quality of the plating layer, the pretreatment process of the workpiece, especially the oil and rust removal, is particularly important. In this article, we will discuss in detail the key points that need to be paid attention to when using zinc-nickel alloy additives, such as the workpiece oil removal and rust removal pre-treatment process.
Plastic plating process occupies an important position in modern industrial production, especially the direct plating of ABS plastics, which can be plated with a beautiful and durable metal layer on the surface of the plastic by means of an appropriate pretreatment process. Colloidal palladium activator plays a crucial role in this process. However, plating factories often encounter the problem of high dosage and high cost of colloidal palladium activator. How to reduce the dosage and cost of colloidal palladium under the premise of guaranteeing the plating effect has become a technical challenge that needs to be solved nowadays.
In the electroplating process, black zinc passivator is widely used in the post-treatment of galvanized layers to improve the corrosion resistance and decorative properties of the coating. However, in practice, the phenomenon of whitish coating sometimes occurs, which not only affects the appearance quality of the product, but also may reduce its protective properties. In this issue, we will analyze the causes of this phenomenon.
In the electroplating processing industry, for beginners, in the face of complex processes and countless specialized knowledge, often feel at a loss. Mr. Zhang, who is interested in building a new electroplating production line by himself, came to Bigely Technology Company, which supplies zinc plating brightener, on the recommendation of a friend, hoping to find a breakthrough to enter the electroplating industry here.
Some customers inquired that in the production process of using matte tin additives, sometimes the plating in the low area of the workpiece is prone to leakage of plating, what is the reason for this?
