[0026] Example 1:
[0027] An anti-rust process for metal parts includes the following steps:
[0028] (1) Degreasing
[0029] The metal parts are polished and put into PA30-2M degreasing solution for dipping and degreasing, the temperature of the degreasing is 50°C, and the time of the dipping and degreasing is 5 minutes;
[0030] (2) Washing
[0031] Then clean the degreased metal parts with water. The cleaning is divided into two steps. The first step is to wash the degreased metal parts with tap water for 2 minutes, and the second step is to wash them with deionized water twice;
[0032] (3) Pickling
[0033] Put the washed metal parts in an etching acid and soak for 3 minutes at 30°C. The composition of the etching acid is 300mL / L HNO3 and 6g / L NH4HF2 aqueous solution. The total acidity of the etching acid is 55 points;
[0034] (4) Wash again
[0035] Soak the acid-etched metal parts in tap water for 20 minutes, then take them out and wash them with running water twice;
[0036] (5) P...

[0044] Example 2:
[0045] An anti-rust process for metal parts includes the following steps:
[0046] (1) Degreasing
[0047] The metal parts are polished and put into PA30-2M degreasing solution for dipping and degreasing, the temperature of the degreasing is 55° C., and the time of dipping and degreasing is 6 min;
[0048] (2) Washing
[0049] Then clean the degreased metal parts with water. The cleaning is divided into two steps. The first step is to wash the degreased metal parts with tap water for 3 minutes, and the second step is to wash them with deionized water three times;
[0050] (3) Pickling
[0051] Put the washed metal parts in an etching acid and soak for 4.5 min at 45°C. The composition of the etching acid is 350mL / L HNO3 and 7g / L NH4HF2 aqueous solution. The total acidity of the etching acid 65 points;
[0052] (4) Wash again
[0053] Soak the acid-etched metal parts in tap water for 25 minutes, then take them out and wash them with running water 3 times;

Example Embodiment
[0062] Example 3:
[0063] An anti-rust process for metal parts includes the following steps:
[0064] (1) Degreasing
[0065] The metal parts are polished and put into PA30-2M degreasing solution for dipping and degreasing, the temperature of the degreasing is 60°C, and the time of the dipping and degreasing is 7 minutes;
[0066] (2) Washing
[0067] Then clean the degreased metal parts with water. The cleaning is divided into two steps. The first step is to wash the degreased metal parts with tap water for 4 minutes, and the second step is to wash them with deionized water 4 times;
[0068] (3) Pickling
[0069] Put the washed metal parts in an etching acid and soak for 6 min at 60°C. The composition of the etching acid is 400mL / L HNO3 and 8g / L NH4HF2 aqueous solution. The total acidity of the etching acid is 75 points;
[0070] (4) Wash again
[0071] Soak the acid-etched metal parts in tap water for 30 minutes, then take them out and wash them with running water 4 times;
