Embodiment 1
[0033] Example 1 Preparation of anode phosphor copper ball
[0034] The anode phosphorus copper ball of this embodiment, its copper raw material selects oxygen-free copper, phosphorus raw material selects yellow phosphorus, and specific preparation method comprises the following steps:
[0035] (1) After melting the yellow phosphorus and oxygen-free copper in an intermediate frequency induction furnace, the phosphor copper solution is evenly prepared by stirring in a magnetic stirring tank, and the phosphor copper solution is sent to the holding furnace for storage. The temperature of the holding furnace is 1128 ~ 1135 ℃;
[0036] (2) The phosphor copper solution prepared in step (1) is produced by the upward drawing method to produce a phosphor bronze rod with a diameter of 20-50MM, and the phosphor bronze rod is continuously stamped, and copper balls of different sizes are punched out in different molds;
[0037] (3) After polishing, deburring, cleaning and drying the copp...
Embodiment 2
[0040] Put the anode phosphor bronze ball prepared in Example 1 into the titanium blue and use it normally.
[0041] After one to several months of use, the titanium blue is taken out of the liquid surface. It can be found that the plating solution in the titanium blue anode bag has a fast flow rate and can be drained. Less, indicating that the black film falls off less.
[0042]Moreover, using the anode phosphor copper balls prepared in Example 1, the anode bag can usually be cleaned once more than six months, the frequency of cleaning the copper ball is reduced by 1 times, the frequency of cleaning the anode bag is reduced by 2 times, and the service life of the anode bag is doubled. The utilization rate can be increased by at least 4%. The utilization rate of copper balls is high, which reduces the cost of tank cleaning and material costs. At the same time, the uniform dissolution of copper balls significantly improves the quality of the coating, and high-quality coatings c...
