Electroless nickel plating is a common and important process, which aims to provide the surface of products with wear-resistant, corrosion-resistant and aesthetic properties. However, in practice, we often encounter the problem of discoloration of the appearance of the plated layer, especially the water stains formed during the drying process after washing, which is the main cause of the poor appearance of the plated layer. To solve this problem, Bigely plating dewatering agent BC-13 can ensure the bright and beautiful appearance of the plated layer.
In the process of using zinc-nickel alloy natural color passivator, when there is a problem with the passivation film, such as blue passivation film, is this caused by the problem of passivator? Actually, it's not. Maybe it's the plating solution.
In the previous article we mentioned two factors affecting the alignment in the low area in zinc-nickel alloy plating process, respectively, sodium hydroxide and zinc concentration, which is analyzed from the point of view of the concentration of the main salt of the plating solution, in fact, there is another factor that affects the low zone of the alignment factor, that is, the concentration of the complexing agent.
Mr. Tu from Wenzhou, Zhejiang Province is the owner of a processing plant that processes plastic plating and multi-layer nickel plating. Recently, Mr. Tu found that the palladium activation working solution he used in the production process would produce more hydrochloric acid fog. Considering that the acid fog would pollute the environment and harm human beings, Mr. Tu wanted to find a colloidal palladium water without acid fog.
Electroless copper plating is a technology that deposits a copper coating on the surface of a substrate by means of a chemical reaction without an applied current. This technology is widely used in the electronics industry, printed circuit board manufacturing and other areas where high electrical conductivity and excellent surface properties are required. In electroless copper plating solution, accelerator is one of the crucial additives, which can significantly accelerate the copper plating reaction rate, improve the quality of plating and production efficiency.
Mr. Liu in Huizhou, Guangdong Province, is an electroplating factory owner engaged in the galvanization processing of various hardware products and stamping parts. Recently, Mr. Liu found that the black passivation solution always exceeds the phosphorus standard when discharging wastewater, as this violates the discharge standard of the electroplating park, so Mr. Liu would like to replace a phosphorus-free black zinc passivation solution in a hurry.
