铜材质酸洗复合缓蚀剂Lan-826和苯并三氮唑的最佳配比

Optimized proportion of Lan-826 and benzotriazole for the composite corrosion inhibitor in acid cleaning to copper material

详细考察了在对铜及铜合金进行酸洗过程中,单独加入Lan-826、苯并三氮唑以及按不同配比混合加入时腐蚀率的变化情况,确定了混合加入缓蚀剂的最佳配比。

The rosion inhibitor pickling to the gly, or adding paper comes to a conclusion on the optimized proportion of putting in mixedly the cor- , based on the detailed observation to the corrosion rate change of the process in acid copper and copper alloy, under the condition of adding Lan - 826 or benzotriazole sin- the mixed compound of the above two elements with different proportion.
