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:
In the pre-treatment stage of the plating process, conventional pickling processes (hydrochloric acid, etc.) are usually used to remove oxidized layers and rust from the surface of the workpiece. However, this process can lead to hydrogen embrittlement of the plated layer, which significantly affects the mechanical properties and service life of the plated product. Hydrogen embrittlement is a phenomenon in which the ductility and toughness of a material are significantly reduced in the presence of hydrogen, leading to an increase in its brittleness and susceptibility to fracture during use.
With the continuous development of modern industry, alloy workpiece has been widely used in many fields with its excellent performance. However, in the surface treatment process of alloy workpiece, chemical degreasing is an essential and important process. Corrosion sometimes occurs after chemical degreasing of alloy workpieces, which makes many engineers and technicians very confused. Below we will discuss the root cause of this problem from various perspectives.
The correct use of a plating dewatering agent can have a positive impact on the plated layer after the plated product has been rinsed in water. In this article we will talk about what benefits can be achieved.
As we all know, in the production process of plastic plating, the colloidal palladium adsorbed on the surface of the plastic workpiece after palladium activation does not have catalytic activity, which is due to its surroundings are wrapped by divalent tin ions, the use of plastic plating accelerator can dissolve the palladium around the divalent tin so that it is exposed to deal with, so that palladium ions will have catalytic activity. So what do we need to pay attention to when we use the plastic plating accelerator?
Electroplated colored zinc passivation process is vital in the corrosion protection of steel and metal products. The passivation process is mainly divided into two types: trivalent chromium passivation and hexavalent chromium passivation, and each of these two technologies has its own advantages and disadvantages. In this article, a detailed comparison of trivalent chromium and hexavalent chromium passivation will be made in terms of the performance of the passivated film layer, production costs and environmental costs, in order to help plating factories to choose the appropriate passivation process!
