Embodiment 1
[0034] Preparation of electrolytic paint stripper:
[0035] Sulfuric acid (98%) 40g
[0036] Urea 5g
[0037] Hydroxyethylidene diphosphonic acid 5g
[0038] Benzyl alcohol 10
[0039] Isopropanol 10
[0040] Sodium sulfate 3g
[0041] Fatty alcohol polyoxyethylene ether 2g
[0042] water 25g
[0043] Add calculated weights of water, sulfuric acid, urea, hydroxyethylidene diphosphonic acid, benzyl alcohol, isopropanol, sodium sulfate, fatty alcohol polyoxyethylene ether into the stirring tank, and mix well to obtain a water-soluble electrolytic stripping paint agent.
[0044] Paint stripping experiment
[0045] Submerge the workpiece to be stripped into the electrolytic tank, which contains the electrolytic paint stripper, place the workpiece to be stripped on the cathode, turn on the power, and perform electrolysis. The temperature of the electrolytic paint stripper is at 35°C, the current density is 15A / dm 2 , take it out after 5 minutes of electrolysis, wipe it cl...
