摘要
介绍了一种去铝材表面机械纹路的化学酸洗液,通过正交试验得到的最佳配方为:每1L溶液中含100gNH4F、68gHBF4、35mLH2O2和0.12gTx-10(壬基酚聚氧乙烯醚),时间10min,温度50°C。各因素对酸洗效果的影响作用由大到小依次为:NH4F>HBF4>H2O2>酸洗时间。该工艺操作简单,去纹速度快,效果好。
A chemical pickling solution for eliminating mechanical streak on the surface of aluminum alloy was introduced.The optimal formulation determined by orthogonal test is as follows：100 g NH4F,68 g HBF4,35 mL H2O2,and 0.12 g Tx-10（polyoxyethylene nonylphenyl ether） in 1 L of water,time 10 min and temperature 50 °C.The affecting factors on chemical pickling are in the following descending order：NH4F HBF4 H2O2 time.The process has advantages of easy operation,fast de-streaking and good effectiveness.
