In the current condition of high environmental protection requirements, traditional Cr(VI) passivators are gradually being eliminated from the market due to their toxicity and pollution.
In the plating process using hard chrome additives, localized non-plating is a common problem. This not only affects the aesthetics and uniformity of the plating layer, but also may lead to a decline in product performance and failure to meet the requirements of use. So, why does hard chrome plating have localized non-plating?
In the electroplating process, degreasing is a crucial step that directly affects the quality of the subsequent plated layer. In this article, we will discuss how to check the degreasing quality of parts after using steel electrolytic degreasing powder.
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.
