Embodiment 1
[0038] A continuous cleaning process for the surface of metal plated parts, comprising the following steps:
[0039] Step a: Rust removal: put the metal plated parts to be cleaned into hydrochloric acid solution, the concentration of the hydrochloric acid solution is 10g / L, and the temperature is 70°C, and remove the surface particles and rust of the metal plated parts to be cleaned;
[0040] Step b: water washing: wash the metal plated parts after derusting in step a with ultrasonic water for 3 minutes;
[0041] Step c: degreasing: put the metal plated parts washed in step b into a degreasing solution at a temperature of 80° C. for 5 minutes to remove the grease on the surface of the metal plated parts; the 1 L degreasing solution is composed of 20 g of Prepared by adding water to sodium phosphate and 20g of sodium carbonate decahydrate solution;
[0042] Step d: Washing: ultrasonically wash the metal-plated parts degreased in step c once, and the duration of ultrasonic wash...
