[0002] In the current field of impurity removal equipment technology, nickel plating technology is a process of depositing a nickel layer on the surface of another metal. It is often used to improve the corrosion resistance, decorativeness and mechanical properties of the metal surface. Nickel plating technology is usually divided into three types: electrolytic nickel plating, hot-dip nickel plating and chemical nickel plating. Electrolytic nickel plating is the most common technology. After long-term use, nickel plating electrolyte has metal impurities and precipitation inside, which affects the nickel plating effect of subsequent products. Therefore, it is necessary to use an impurity removal device to remove impurities from the electrolyte.
