Plasma Technology

What is Plasma technology?

To understand what plasma technology actually is, a simple view on the different states of aggregation is enough. It lies in the nature of materials to be merged into the next state of aggregation when they are supplied with of energy. Frozen water for example becomes liquid through a constant energy input, and with further energy it gets into a gaseous state.
Next to the three aggregation states there is a further state – the plasma.

With the plasma technology it is possible to supply gasses with further energy, so that they merge into the state of ionisation.
Plasma is highly energetic.

This charge is transferred to the surface of the processed material. Thus the surface will be merged on a higher energetic level and gains better characteristics, which is for example by adhesion.

The creation of highly energetic plasma

Our plasma generators work on the high-frequency-converter-principle. A Voltage source of 240V or 400V will be modulated to a high frequenzy in the plasma generator and creates a high voltage arc.

Simultaneously, compressed air runs through the electrode. The air-oxygen becomes ionised and leaves the electrode as highly energetic plasma.

Difference between low-pressure and atmospheric plasma

Low-pressure plasma requires a surrounding which is below the normal atmospheric pressure. This results in the fact, that the treatment has to be done in a closed system.

The problem is obvious: the treatment can only be done batch-wise. An integration in a continuous production process is not possible.

Atmospheric plasma (also atmospheric pressure plasma) can even be realised under the normal atmospheric pressure. Because a low pressure system is not required any more, the technology can be used directly in a continuous production process. The gas discharge of the atmospheric plasma can directly take place on the work piece, e.g. on the conveyor, which can lead to an enormous time saving.
