In the electroplating industry, the appearance and corrosion resistance of galvanized black passivated products have always been the focus of manufacturers' attention. Many manufacturers often encounter the problem that the appearance of galvanized black passivate is not black enough and the salt spray performance is not up to standard during the production process of using trivalent chromium black zinc passivate. In order to help electroplating manufacturers to solve this problem, we have summarized a three-step solution through our service cases over the years.
In the electroplating industry, air agitation, a critical process operation, has a profound effect on the quality of the plated layer. The following will explore in detail how air agitation affects plating quality and explain why it is important to select a potassium chloride galvanizing brightener that supports air agitation.
Mr. Lin operates a company that specializes in acid zinc plating and processing. His factory has been enjoying a reputation for stable plating quality and in the industry. However, some time recently, Mr. Lin encountered a tricky problem: when using potassium chloride zinc plating brightener, the plating layer appeared to have bad alignment and lack of brightness abnormality.
Alkaline galvanizing is a common surface treatment process widely used in industrial manufacturing and maintenance. As a core component in the alkaline galvanizing process, the content of sodium hydroxide (NaOH) plays a key role in the quality and dispersing ability of the coating. In this paper, we will discuss how the sodium hydroxide content affects the dispersing ability of the plated layer when using alkaline galvanizing brighteners.
Mr. Fu's company is a tin-plating factory in Shenzhen that processes electronic products. The parts they produce need to have good welding properties, otherwise they will directly affect the conductivity and service life of electronic products. However, recently Mr. Fu has encountered problems with the appearance of his products being not white enough and poor welding performance when using dull tin additives.
In the cases where Bigely Technology has provided services, the problem of color change after acid tin plating has always been a pain point for customers. However, this problem can be solved by using our acid tin plating additive.
