Decontamination and paint spraying process after sand blasting and electroplating

The invention relates to the field of metal surface treatment, and discloses a decontaminating and paint spraying process after sand blasting electroplating, which comprises the following steps: S1, blowing off floating sand on the surface of a metal material by using an air gun; s2, sand materials which are attached to the rough positions generated on the surface of the metal material part and are difficult to blow open through an air gun are polished and cleaned through an angle grinder or abrasive paper; and S3, after the sprayed material on the surface of the metal part is completely cleaned, cleaning and airing are conducted. According to the decontaminating and paint spraying process after sand blasting and electroplating, after sand residues on the metal surface after sand blasting are cleaned, the surface of a paint film formed by subsequent paint spraying can be smoother, the thickness of the paint film can be more accurately mastered, fine protrusions cannot be generated due to the sand residues on
