Example Embodiment

[0032] Embodiment 1: A method for surface treatment of an electroplated copper door of the present invention, wherein:

[0033] The above methods include electro-degreasing the copper door;

[0034] Clean the copper door after degreasing by electricity;

[0035] Perform activation treatment on the above-mentioned cleaned bronze door;

[0036] Perform alkali copper treatment on the above-mentioned activated copper gate;

[0037] Clean the above-mentioned copper door after alkali copper treatment;

[0038] Perform acid copper treatment on the above-mentioned cleaned copper door;

[0039] Clean the copper door after acid copper treatment;

[0040] Perform gun black treatment on the above-mentioned cleaned copper door;

[0041] Clean the bronze door after gun black;

[0042] Passivate the above-mentioned cleaned copper door.

[0043] The above electrolytic oil treatment is to put the copper door into an aqueous solution with 25g / L-30g / L sodium phosphate and 10g / L-20g / L sodium carbonate, and the c...

Example Embodiment

[0055] Second embodiment: This embodiment is basically the same as the first embodiment, the difference is:

[0056] The above electrolytic oil treatment is to put the copper door into an aqueous solution with 29g / L sodium phosphate and 15g / L sodium carbonate, and the current flow into the cathode is 3A / dm 2 , The duration is 30s.

[0057] Following the previous process, two independent cleanings are carried out on the copper door that has been electro-de-oiled, that is, the copper door that has been electro-de-oiled is cleaned with clean water, and then cleaned again to ensure that the copper can be removed. The door is clean, and the next process will not be affected by the remaining impurities or residual liquid on the copper door.

[0058] Connected to the previous process, before the activation treatment, after electrolytic degreasing and cleaning, it also includes the step of sulfuric acid treatment to clean the copper door after sulfuric acid treatment. The sulfuric acid conce...

Abstract

The invention relates to a method for surface treatment of an electroplated copper door. The copper door treated by the existing electrochemical method has good corrosion resistance, but the accuracy of the existing electrochemical treatment process is poor, and the quality is not high, which is difficult to meet the current high-quality requirements. The present invention relates to a method for surface treatment of an electroplated copper door, wherein the method includes performing electrolytic degreasing treatment on the copper door; cleaning the copper door after electrolytic degreasing; performing degreasing on the cleaned copper door Activation treatment: performing alkali copper treatment on the copper gate after activation treatment; cleaning the copper gate after alkali copper treatment; performing acid copper treatment on the cleaned copper gate; Clean the copper door after cleaning; Carry out gun black treatment to the copper door after the cleaning; Clean the copper door after gun black; Carry out passivation treatment to the copper door after cleaning. Optimize the copper door surface treatment process, improve the accuracy of the copper door surface treatment process, and improve product quality.

Description

technical field [0001] The invention relates to a method for surface treatment, in particular to a method for surface treatment of an electroplated copper door. Background technique [0002] The existing copper door surface treatment is divided into chemical surface treatment and electrochemical surface treatment. Due to the fast electrochemical speed and high efficiency, it is suitable for mass production, and the process flow of chemical surface treatment and electrochemical surface treatment is roughly the same. For degreasing, descaling, descaling - washing - pickling and polishing - washing - neutralization - washing - coloring treatment - washing - drying and other post-processing. [0003] Existing electrochemical method: the copper after routine cleaning is anodically electrolyzed in the following solution; [0004] Sodium carbonate (Na 2 CO 3 ) is 75g / L; [0005] Ammonium sulfate ((NH 4 ) 2 SO 4 ) is 25g / L; [0006] Ammonium nitrate (NH 4 NO 3 10g / L; [0...
