Recently a customer came to consult the pyrophosphate copper plating brightener, he is doing zinc alloy plating with cyanide-containing alkaline copper, but it is easy to produce defective products, and the plating speed is slow, and he would like to know whether there is any other alternative products. Then pyrophosphate copper plating brightener is a good alternative product.
Acid copper plating brighteners play a key role in the plating process, directly affecting the dispersing ability of the plating solution and the quality of the plated product. The dispersing ability of the plating solution is related to the uniformity and covering ability of the plated layer, which in turn affects the appearance and function of the plated parts. Therefore, how to choose acid copper plating brightener is crucial to improve the effect of plating process.
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.
What are the characteristics of steel chemical degreasing powder, we will talk about it today.
Bigely trivalent chromium blue zinc passivator BZ-212 is a new type of environmentally friendly passivation agent, which can effectively avoid the formation of hexavalent chromium in the passivation film layer, thus meeting the environmental protection requirements and market demands.
