Cleaning Operations - Non-atomized Cleaning

Non-atomized cleaning is a process for applying coatings to surfaces. The controlled spraying increases the material transfer efficiency and reduces styrene emissions by minimizing overspray loss.

This process is accomplished by three means:

• Operation of the spray gun at the lowest applicable fluid tip pressure.
• Use of proper spray gun handling techniques.
• Use of close capture mold configurations to minimize overspray of the surface area.

Controlled spray has the additional benefit of reducing waste and other non-value activities associated with overspray. The work area requires less frequent cleanup, and PPE stays cleaner and can be used longer before it needs to be replaced. When selecting equipment, it is important to know the flow rate requirement - or the amount of material that will be sprayed in a given period.

The flow rate is primarily controlled by three factors:

• Size of the spray tip and pump pressure
• Resin viscosity
• Resin temperature

Non-atomized discharge of a cleaning solvent can be done into a waste container that is kept closed when not in use.
