Electrolytic Porous alumina Ceramic Membrane for Zinc Nickel Alloy Anode
Introduction of Zinc Nickel Alloy Anode Electrolytic Ceramic Membrane Products
This is a new technology that has only been applied in recent years, using ceramic membrane to protect metal anodes instead of traditional metal anodes such as nickel or steel, which can prevent chelating agents and other organic components from migrating from the electrolyte, to prevent the oxidation.
The zinc nickel alloy anode electrolytic ceramic film produced by our company is carefully formulated with high-quality ceramic raw materials and has excellent corrosion resistance to strong alkalis. Due to the high temperature (around 1500 degrees) used for firing (resulting in higher raw material costs, kiln investment costs, and firing costs), the mechanical strength is relatively high. The key technology of the product lies in its high porosity and uniform distribution of pores, moderate pore size, thin cylinder wall (5-7mm), very low resistance during electrolysis, and the ability to obtain uniform current distribution, which is the key to product performance.

It also reduces the formation of cyanide, organic carbon, and carbonate products, improves the efficiency of electroplating. The electroplating efficiency of zinc nickel plating solution can also be maintained at the initial level for many years, reducing operating costs.
The production lines for installing ceramic membrane anode equipment worldwide are increasing year by year, with a large amount of usage. Some production lines have been in operation for more than 10 years. This is a proven and mature technology.
