The importance of a properly selected and properly maintained racking system cannot be over emphasized.These areas play an
important roll in the selection of a properly designed racking system:
- The pretreatment system for drainage.
- The conveyor system for proper grounding
- The booth design for ease of application.
- Loading and off-loading areas for proper space.
The efficiency of your electrostatic application
equipment depends on proper grounding from the conveyor system to the parts in process. Powder applied over and over on the racking system will create a highly insulated surface that will reduce the
efficiency of the coating application equipment. Therefore, the racking system will require cleaning on a regular basis.
This can be accomplished in a number of ways, the most common of which is the removal by incineration. The racks are
placed on a furnace and elevated to a temperature high enough to burn the coating to an ash that is easily removed with water. Another method commonly used
is chemical removal, although this process is often messy, expensive, dangerous and sometimes illegal.
From the most elaborately designed racking system to the simplest style "S" hook, regular cleaning of the racking system will insure good grounding and maximum transfer efficiencies of powder
resulting in lower material costs.
