In the production process of electroplating, do you have such a distress: workpiece after zinc plating after trivalent chromium blue zinc passivation, placed for a period of time the surface will be yellow, seriously affect the quality of the product, the customer will not accept such a product, then what to do?
Zincate galvanizing brightener BZ-513 is the product of Bigely Technology, which integrates the advantages of domestic and foreign galvanizing technology and adopts the imported raw materials from Germany, which is suitable for cyanide-free alkaline zinc process, with simple process maintenance, good brightness and no brittleness of plating, and uniform thickness in high and low zones. Then, how to maintain BZ-513 when using?
The pH value of Bigely neutral tin plating process is nearly neutral, which is suitable for the plating of materials susceptible to acid, alkali influence or corrosion, such as special glass, ceramic materials as the substrate of the component solderable ends, leads. So, how should we maintain the plating solution in daily production?
When methanesulfonic acid tin plating additive is used, the acidity of the plating solution is relatively low, and the corrosion is relatively small. In the use of methylsulfonic acid tin plating additives, we can understand the advantages and disadvantages of additives through performance tests. The following takes the methylsulfonic acid tin plating additive Sn-819 from Bigely Technology as an example to conduct a performance test:
In the field of electroplating, deep plating capability refers to the ability of the plating solution to deposit plated layer in the area of high and low current density, which determines the uniformity of the plated layer in the deep holes, blind holes and pits of the workpiece. Tin plating additives play an important role in enhancing deep plating capability.
Electrolytic degreasing in electroplating production is a pretreatment process that utilizes an electrolytic process to remove grease and organic contaminants from the surface of metal workpieces. Cleaning the metal surface prior to plating is critical, as oil and grease can hinder the uniform deposition of the plating layer and may lead to quality problems such as peeling and flaking of the plating layer. Electrolytic degreasing powder is a chemical agent used in industrial production to remove grease and other impurities from metal surfaces, mainly by electrolysis. The following factors should be considered when selecting a suitable electrolytic degreasing powder:
