Embodiment 1
[0067] A liquid phase ion derusting solution is prepared, and the liquid phase ion derusting solution contains: 2 wt% ammonium chloride, 1 wt% potassium sulfate, and the rest is deionized water.
[0068] The specific rust removal process is as follows:
[0069] The workpiece A to be derusted is made of No. 45 steel, the size is 70mm×50mm×2mm, and it is exposed to the outdoors for two weeks.
[0070] a. Install the steel material to be derusted on the hanger, soak it in the sodium hydroxide solution with a prepared concentration of 20wt% for 15 minutes to degrease, and rinse it with deionized water for 2 minutes after degreasing;
[0071] b. Heat the liquid plasma derusting solution to 80°C, put the hanger with the steel to be derusted on the support of the liquid derusting machine, and immerse in the liquid derusting solution; put the liquid derusting The positive pole of the rectifier of the machine receives derusting steel, the negative pole of the rectifier is connected in...
