In the plating industry, zinc replacement solutions are an important part of the pre-treatment of aluminum and its alloys. Aluminum, although widely used for its lightweight and high strength properties, must first overcome its naturally occurring oxide film and low surface activity when it comes to plating other metal layers on its surface. This is because the oxide layer significantly reduces the adhesion of the metal layer. The application of zinc replacement fluids is the key to enhancing this adhesion.
In the steel surface treatment process, the application of steel chemical degreasing powder is crucial, which is directly related to the quality of subsequent coating, plating, welding and other processes. However, in practice, sometimes degreasing is not clean, which is mainly caused by the following factors:
In modern industrial production, plating technology is widely used in many industries, such as automotive, electronics, aviation, etc., to improve the wear resistance, corrosion resistance and appearance of workpieces. Moisture treatment in the plating process is crucial, because moisture will directly affect the bonding force of the plating layer, film-forming effect and even the performance of the plating layer. To solve this problem, dewatering agents have been developed to provide a suitable solution for the plating industry.
In the production of electroless nickel plating for mechanical parts, plating factories often face the following two troubles: one is the untimely supply of electroless nickel plating additives; the other is the lack of technical service. These problems not only affect the customer's production efficiency, but also may adversely affect the plating quality. However, when the customer, Mr. Lin, encountered these problems, he chose to come to Bigely Technology for inspection and got a satisfactory solution.
In the electroplating industry, trivalent chromium colored zinc passivator is widely used due to its environmental friendliness and good corrosion resistance. However, when using this passivator, the pH value becomes one of the factors affecting the quality of the passivate layer. In this paper, we will discuss in depth how pH affects the quality of the passivate layer.
In the development and use of alkaline zinc brightener, zinc oxide as an important component, its role should not be underestimated. This article will introduce the role and benefits of zinc oxide in alkaline zinc brightener from several aspects.
