Zincate galvanizing brightener BZ-513 is the product of Bigely Technology, which integrates the advantages of domestic and foreign galvanizing technology and adopts the imported raw materials from Germany, which is suitable for cyanide-free alkaline zinc process, with simple process maintenance, good brightness and no brittleness of plating, and uniform thickness in high and low zones. Then, how to maintain BZ-513 when using?
1, To strictly control the impurity content of the added raw materials, especially on the plating quality has a greater impact on the copper, iron, lead and other trace metal impurities. The plating solution should be treated with activated carbon and zinc powder every half month.
2, Regularly analyze the content of zinc and alkali in the plating solution, and make zinc and alkali to maintain a certain ratio. Generally rack plating control alkali: zinc = 10:1; barrel plating control alkali: zinc = 12:1, and in the production process more Hull tank to detect whether the plating solution is in a normal working condition.
3. The anode area used for zincate zinc plating is usually anode area: cathode area = (1.5-2):1. The amount of zinc metal dissolved in the plating solution depends on the concentration of alkali dissolved in the plating solution, the anode area, the temperature, the amount of carry-out and carry-in, and the current efficiency. It is recommended that some or all of the zinc anode plates be removed when plating is stopped to prevent elevated zinc levels in the plating solution.
4, The operating temperature of this process, in the zincate plating solution is 20-30 ℃ range can be bright and detailed galvanized layer, the best plating speed and go ability. The temperature is high, the zincate galvanizing brightener consumption increases, low current area is not easy to bright, covering ability and dispersion ability will be worse; temperature is too low, will make the current efficiency is reduced, affecting the deposition speed of the galvanized layer.
