Abstract
The invention discloses a method for derusting copper and copper alloy and aims to provide a method which is simple in operation and capable of efficiently removing rust stains on copper and copper alloy. The method sequentially comprises the following steps of (1) uniformly mixing 1 part by weight of acidic deruster and 5-10 parts by weight of water to obtain a mixed derusting solution; (2) soaking copper to be derusted and copper alloy to be derusted into the mixed derusting solution with the temperature of 40-60 DEG C for 30-200s; (3) taking out the soaked copper and copper alloy, washing to be clean, and then, placing the copper and copper alloy into an alkaline solution to neutralize; (4) flushing the copper and copper alloy neutralized in the step (3) by using cold water, and then, flushing the copper and copper alloy by using hot water. The method belongs to the technical field of metal cleaning.
