Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, and more specifically, to a chemical nickel plating processing device. Background Art

[0002] Both chemical nickel and electroplating nickel are methods for protecting metal surfaces. Chemical nickel is a coating method that uses a chemical reaction to form a protective nickel alloy layer on the metal surface. This coating features uniform nickel alloy particles, high hardness, and high wear resistance, making it widely used in many industries, such as the automotive, food, and medical industries. Electroplating nickel is an electrochemical method for depositing pure nickel on a metal surface. In an electrolyte, the ions in a solution containing nickel ions are reduced to metallic nickel. This coating is very evenly distributed on the substrate surface and provides excellent corrosion resistance.

[0003] Chemical nickel is usually applied to the surface of metal parts by dissolving a reagent in a bath. Without a disturbance mechanism, uneven concentration of the bath will lead to reduced coating quality and poor overall effect. Utility Model Content
