The Mechanical Machining Requirements For Surface Painting

Posted by: William 2021-11-14 Comments Off on The Mechanical Machining Requirements For Surface Painting

Machining coating is to cover the metal and non-metal surface of the machined parts with a protective layer or a decorative layer. So what are the requirements for coating on the workpiece after machining?

The Mechanical Machining Requirements For Surface Painting

  • 1. The surface of the machined workpiece that needs to be painted must be removed from rust, oxide scale, grease, dust, soil, salt and dirt before painting.
  • 2. Before rust removal, use organic solvents, lye, emulsifier, steam, etc. to remove grease and dirt on the surface of the workpiece.
  • 3. The time interval between shot blasting or manual derusting of the surface to be coated and primer coating should not be more than 6h.
  • 4. The surfaces of the riveting parts in contact with each other must be painted with a thickness of 30-40μm anti-rust paint before connecting. The lap edges should be sealed with paint, putty or adhesive.
  • 5. The primer damaged by machining or welding must be repainted.

Mechanical processing requires the above 5 points for coating. When coating mechanical processing parts, the processing safety technology management should be carried out, the implementation of the relevant national standards of the coating operation safety regulations, the improvement and perfection of safety protection measures, and the production safety and personnel must be guaranteed. It is safe and must comply with relevant environmental protection requirements.
