Electroplating is a physico-chemical process that utilizes electrolysis to form a uniform, dense, and well-adhered coating on metals, alloys, or other conductive materials. During the plating process, the cleanliness of the surface of the workpiece is directly related to the quality of the plating. Especially, electroplating degreasing process is one of the key steps to ensure the quality of electroplating.
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.
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.
Reducing agent plays a central role in the electroless copper plating solution, and its selection and use have a significant impact on the quality of the copper chemical coating, deposition rate, and the stability and efficiency of the entire electroless copper plating process.
Electroless nickel plating technology is widely used in industrial fields, and the hardness of nickel layer is an index to guarantee the wear resistance of parts. This article summarizes the main factors affecting the hardness of electroless nickel plating layer: bath composition, plating solution pH, temperature.
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.
