Embodiment 1
[0019] A stainless steel polishing process, comprising the following steps:
[0020] (1) Surface stain cleaning: soak the stainless steel workpiece to be polished in acetone for 30 minutes, then take it out, rinse the surface with potassium bicarbonate solution for 5 minutes, and dry to constant weight;
[0021] (2) Ultrasonic cleaning: Soak the stainless steel workpiece treated in step (1) in sodium sulfite solution for 10 minutes, and then use ultrasonic treatment for 3 minutes. After taking it out, rinse the surface with deionized water for 3 minutes, and dry to constant weight;
[0022] (3) Surface activation: Put the stainless steel workpiece treated in step (2) into a closed impregnation tank, vacuumize the tank to -0.12MPa, then inject the activation solution into the impregnation tank, and immerse the stainless steel workpiece. Treat for 2 hours, then take out the stainless steel workpiece, rinse the surface with sodium carbonate solution for 3 minutes, and dry to cons...
