Expert Surface Perparation, Dry Strippng with Plastic Media Blasting

Glossary

Blasting pressure -
the amount of pressure with which the media is applied from the nozzle, measured in pounds per inch (psi)
Chemical stripping -
the use of liquid chemical to remove a top coating. This is commonly done by immersing the part in a tank
Dry stripping -
the use of dry media, usually an abrasive, to remove a top coating from a part. Common dry stripping techniques include sanding, sandblasting, and plastic media blasting
Etching -
the process of cutting or incising lines or grooves into a surface of a material or part
Flow rate -
the volume of media passing through the nozzle, usually measured in pounds per minute
Glass beading -
the use of glass beads to etch, clean or prepare surfaces
Nozzle -
the end of the media blasting hose through which the media is expressed. An operator can control the nozzle's aperture and angle to the workpiece
Plastic media blasting -
a dry stripping technique utilizing plastic particles made in various degrees of hardness and cut into various shapes
Rotisserie -
a device for rotating parts to give the operator access to hard to reach areas, such as interior angles or the underside of a part
Sandblasting -
a dry stripping technique utilizing silica sand as the abrasive media
Substrate -
the underlying surface structure of a part or material
Surface coating -
a material adhered to the top surface of a part, commonly a finish such as paint, powder coating or sealant
Workpiece -
the part or material being processed
