Special note on the operation of the plasma process
6.1
General description
Treating surfaces with atmospheric plasma has several advantages. These are e.g. the
increase of the surface energy to produce a better wettability of the surface. An optimal
surface wetting is the first and often decisive step to achieve excellent print quality,
homogeneous coating, uniform varnishing or an integrally bonded application of
adhesives. The bond at this interface often determines the durability and adhesive
strength of this material pairing.
Atmospheric-pressure plasma increases throughput in many industrial processes, while
at the same time saving costs for solvents or chemical primers. We have successfully
integrated our plasma products into the following application fields:
•
Cleaning of metal, glass and plastics
•
Surface activation and surface functionalisation for optimised wettability
•
Plasma-assisted laminating process
•
Plasma-assisted adhesive bonded joints
•
Plugging and sealing
•
Plasma induced reduction of metal surfaces
•
Chemical-free bleaching of textiles
•
Plasma sterilisation of fabric
•
Handling of food products for quality and shelf life
•
Sterilisation of thermally-unstable plastics
•
Air purification, odour and germ reduction
•
Multi-component injection moulding
Practically all technical material classes can be efficiently processed under atmospheric
pressure:
•
Metals and metal alloys
•
Plastics and composite materials
•
Glass, ceramics, inorganic composites and natural stone
•
Real leather and imitation leather
•
Natural fibres, wood and paper
Since the plasma treatment is always just one part of the entire process, it is important to
know the overall influences on the surface properties in order to achieve an optimal result.
Typical influencing factors are:
•
Plasma process: Distance to the substrate, speed, nozzle geometry
•
Substrate/ workpiece: Material composition, contamination, electrical conductivity,
thermal conductivity, moisture content
•
Workpiece treatment: Contamination before or after the plasma process, the time
duration between the plasma process and the follow-up process
