[0028] Example 1
[0029] In this embodiment, the acid zinc-nickel alloy electroplating process is used for automobile parts. The specific steps of the electroplating process are as follows:
[0030] (1) Chemical degreasing: chemical degreasing is performed on the surface of the parts to be plated. The chemical degreasing uses HCM-01 with a concentration of 60g / L, the degreasing temperature is 65°C, and the degreasing time is 12 minutes; then put it in for cleaning Wash in the tank for 10s;
[0031] (2) Primary anodic electrolysis: send the plated parts after chemical degreasing into the anodic electrolytic cell for primary anodic electrolysis, at 35℃ and 3A / dm 2 Conduct electrolysis for 4 minutes under the conditions of, and then put it into the washing tank to wash for 10 seconds;
[0032] (3) Pickling: send the plated parts after an anode electrolysis into a 200ml / L hydrochloric acid pickling tank, pickling at room temperature for 6min, and then put it in the washing tank for 300s;...

[0044] Example 2
[0045] In this embodiment, the acid zinc-nickel alloy electroplating process is used for automobile parts. The specific steps of the electroplating process are as follows:
[0046] (1) Chemical degreasing: chemical degreasing is performed on the surface of the parts to be plated. The chemical degreasing adopts HCM-01 with a concentration of 80g / L, the degreasing temperature is 55°C, and the degreasing time is 8min; then put it into cleaning Wash in the tank for 5s;
[0047] (2) Primary anodic electrolysis: send the plated parts after chemical degreasing into the anodic electrolysis cell for one anodic electrolysis, at 45℃ and 6A / dm 2 Conduct electrolysis for 2 minutes under the conditions of, and then put it into the washing tank to wash for 5 seconds;
[0048] (3) Pickling: send the plated parts after an anode electrolysis into a 300ml / L hydrochloric acid pickling tank, pickling at room temperature for 4min, and then put it in the washing tank for 200s;

[0060] Example 3
[0061] In this embodiment, the acid zinc-nickel alloy electroplating process is used for automobile parts. The specific steps of the electroplating process are as follows:
[0062] (1) Chemical degreasing: chemical degreasing is performed on the surface of the parts to be plated. The chemical degreasing uses HCM-01 with a concentration of 70g / L, the degreasing temperature is 60°C, and the degreasing time is 10 minutes; then put it in for cleaning Wash in the tank for 8s;
[0063] (2) Primary anodic electrolysis: send the plated parts after chemical degreasing into the anodic electrolytic cell for one anodic electrolysis, at 40℃ and 3-6A / dm 2 Perform electrolysis for 3 minutes under the conditions of, and then put it into the washing tank to wash for 8 seconds;
[0064] (3) Pickling: send the plated parts after an anode electrolysis into a 250ml / L hydrochloric acid pickling tank, pickling at room temperature for 5min, and then put it in the washing tank for 250s;
