Abstract:
This paper studied the preparation of a kind of environmentally friendly aluminum alloy wire passivation solution. During the experiments, the composition of the passivation solution has been studied, and the optimum content of each component has been achieved. In addition, the effect of passivation technical conditions on the passivation performance has been examined. The results show the optimal composition of passivation solution as follows: 6%~8% of w(sulfuric acid), 4%~6% of w(sodium sulfate),6×1 0-4~8×1 0-4、 of w(copper sulfate), and 2%~3% of w(urea); the optimal passivation technical condition is: passivation temperature 30~40 ℃, and passivation time 10~20 s.For the aluminum alloy wire,the performance of the passivation solution was comparable to the chromate passivation solution passivation.
Key words: High efficiency, Environmental protection, Passivation solution, Component, Aluminum alloy wire
