Du' cathode®

Du' cathode® is a zinc electrolytic cathode plate developed by our company. The production process of this product has been patented. The cathodes are designed to perfectly implement the entire zinc electrolytic process and automatic or manually stripping operation. After many years of practical tests, it is proved that our product has solved various operational problems exposed in the use of existing cathode plates in the market.

 

I. Maintenance Free

Du’ cathode® is the only proven maintenance free cathode in domestic and overseas market. Because of the use of most advanced manufacturing process and material, during its service time (3 years), no replacement or maintenance of any parts is needed based on given operating conditions. A complete cathode consists of 5 sub-systems. In the following table, we describe details and important design making the Du’ cathode® maintenance free.

II. Long Lifetime

Du’ cathode® Polymer Material Anti-corrosion Coating and Edge Strips One-time Forming Process is a subversion one in the current market.

  • • Complete anti-corrosion
  • • Coating and edge strips do not dissolve, do not fall off during the lifetime of Du’cathode.
  • • Lifetime≥three years

III. Capital Cost Savings

The prices in comparison of three types of cathode plates in the market are approximately as follows:

Du’ cathode®: Ordinary No Corrosion Resistant Cathode Plate: certain European brand partially anti-corrosion cathode plate = 1:0.9:1.5. Based on the above price relationship and service life of cathode plate, we simulated the following short-term capital cost comparison:

It clearly shows that after a short period of 3 years, savings of 65%-70% based on the initial cost can be achieved. Furthermore, the ongoing maintenance issues for using substandard cathodes will additionally increase the cost, while Du’ cathode® is maintenance free and has no maintenance cost. 

 

IV. Increased Zinc Output

The use of Du’ cathode is particularly prominent in the process of artificial zinc stripping. According to continuous observation and statistics by Baohui Group and Shaanxi Zinc Industry Co., Ltd. for more than three years, the time for stripping zinc is shortened from 4-5 hours per day to less than 2 hours. It means the electrolysis time is increased by more than two hours every day, and the output increases by 5-8%, in which the theoretical calculation is consistent with the actual statistics.

V. Reduced Energy Consumption

The company's self-produced explosion bonded contact ensures effective cross-sectional area and conductivity. A powerful explosion causes a shock wave which blows out any impurities and bonds the two metals together. After explosion bonding, the bonded plate is cut into individual explosive bonded contacts. Prior to cutting, a flaw detector was used to find out the edge where the bonding is not fully accomplished, it will then be cut and discarded, so as to ensure the highest quality of our contact.
