1. ELECTROSTATIC SPRAYING

 

• Used to coat an object to,

- reduce corrosion

- protect against scratching

- stop contact with air/water/chemicals/etc

- alter appearance

 

• Electrostatic paintig methods

- increases the production rate

- reduces paint wastage

- are well suited to automation

- give good finishes

 

• The basic process is,

- before/as the paint is sprayed, it is given a negative charge (extra electrons).

- The workpiece is positively charged, thus attracting the paint particles

- The paint is generally sprayed at the workpiece, the electrostatics even out the dispersion, and reduce wastage.
