6 Special notes on using the plasma process
6.1 General description
Treating surfaces with atmospheric plasma has several advantages. Examples include
an increase in surface energy to achieve better surface wetting. Optimum surface wetting
is the first and often most decisive step to achieving a good imprint, a uniform coating, a
consistent coat of lacquer or an integrally bonded adhesive application. The bond at this
boundary layer often determines the longevity and adhesive strength of this material
pairing.
Atmospheric-pressure plasma increases throughput in many industrial processes, while
at the same time saving the costs of solvents or chemical primers.
We have successfully integrated our plasma products into the following application fields:
•
ultra-fine cleaning of metal, glass and plastics;
•
surface activation and surface functionalisation for optimised wetting action;
•
plasma-assisted laminating processes;
•
plasma-assisted adhesive bonded joints;
•
plugging and sealing;
•
plasma-induced reduction of metal surfaces;
•
chemical-free bleaching of textiles;
•
treatment of food products to improve quality and shelf life;
•
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
•
Natural leather and synthetic leather
•
Natural fibres, wood and paper
Since the plasma treatment is always just a single part of the entire process, it is
important that the additional parameters are known in order to achieve an optimum
result.
Typical influencing variables could be:
•
Plasma process: distance from substrate, speed, power setting, type of gas
(compressed air or nitrogen), gas flow, design of exchange modules.
•
Substrate/workpiece: material composition, contamination, electrical conductivity,
thermal conductivity, moisture content.
•
Workpiece treatment: contamination before or after the plasma process, the time
elapsed between the plasma process and the follow-up process.
