Use Of Stainless Steel Cathode Plate

- Nov 07, 2018 -

Permanent Cathodic Electrolysis - Concepts Permanent Cathodic Electrolysis refers to electrolytic cathodes, also known as "starting pole pieces", produced by specialized processing plants. There are two kinds of initial pieces: 1 titanium plate; 2 stainless steel plate. Both can be reused, called "permanent cathodes." At present, the non-embroidered steel plate is widely used, and the permanent cathodic electrolysis method is mainly used for metal electrolytic refining. Electrolysis is based on the principle of oxidation-reduction reaction. Cu2 in the electrolyte is positively charged, flows to the cathode, is concentrated at the cathode, is reduced to metallic copper, and adsorbed on the cathode. The purity of the cathode copper is high. Features of Permanent Cathode Copper Electrolysis Technology Stainless steel cathode plates can be used repeatedly, and do not require home release agents, straightening, etc. in the electrolytic cell. It is protected by cathodic protection in the electrolytic cell and does not corrode. It has been proved that the service life can reach more than 15 years, even if the damage is mostly mechanical damage, and the small mechanical damage is also repaired. Under normal circumstances, the annual damage rate is <1. %. Compared with the traditional method, it has the characteristics of high current density and small pole distance. The current density can reach 350 or so, and the pole distance is about 100cm. 2. Short cathode cycle The cathode cycle is 68 days. The short cycle is beneficial to the quality of the cathode copper and can reduce the chance of long cathode particles. 3. Low disability rate Because the cathode plate is straight, the power line is evenly distributed, and it is not easy to be short-circuited. Therefore, the anode is dissolved more uniformly, and the utilization rate of the anode is improved. 4. Low steam consumption The average steam consumption per ton of cathode copper in the permanent cathode method is below 0.4t, and the traditional method is around 0.6t. 5. High tank voltage, high DC power consumption Advantages of permanent cathode and electrolysis technology 1. Simplified process flow Since the stainless steel cathode plate can be used repeatedly, the tedious production process of the initial pole piece is eliminated, the production process is simplified, and equipment and venue are reduced. And the operator. 2. Good product quality 1 The stainless steel cathode plate is straight and not easy to be deformed, and the power line is evenly distributed during electrolysis, so that the cathode copper is precipitated densely and evenly with few particles. 2 The cathode copper is stripped from the cathode to avoid surface oxidation and contamination caused by the initial sheet during the production and storage process, and an impurity interlayer is formed at the center of the cathode copper after the groove is introduced. 3 The product has no hanging and easy to clean. 3. Large output per unit area The pole pitch is small, the current density is large, there is no production workshop for the initial pole piece, and the area of the electrolysis workshop is small, so the output per unit area is large. 4. Low production cost and good economic efficiency
