Our innovative plasma technology
The term plasma is increasingly used today because plasma technology has already established itself as a key and cross-sectional technology in many industries as a modern technology standard. But what is plasma?
What is plasma?
When it comes to plasma, we speak about the fourth aggregate state – besides solid, liquid and gaseous. By supplying so much energy to a gas that the critical number of electrons leave the atomic shell, the gas is ionized and moves from a gaseous state to a fourth state – plasma is formed. Energy is usually supplied by the application of a high-voltage source. The plasma that is generated is a matter with a high, unstable energy level.
Although physicists and chemists only started talking about plasma in relatively recent times, plasma related phenomena have played a role in the life of human beings ever since primeval times. Lightening created fire and the northern lights made our forefathers contemplate the existence of higher beings. Both of these natural effects are based on plasmatic discharges.
The history of experimental plasma physics began around the year 1700 with attempts to create electrical luminous effects in evacuated glass bulbs. In 1747 Benjamin Franklin invented the lightening conductor and Michael Faraday first raised the question of the four states of matter: solid, liquid, gas and fire as the fourth state (plasma). Werner von Siemens developed the first technical plasma application in 1857 with his ozone generator, which was used to generate ozone by means of electrical discharge.
Ground-breaking developments in lighting technology (neon tubes, glass lasers, plasma displays), and in plasma chemistry, for example, in the production of diamond coatings or plasma welding, are based on the ability to master the fourth state of matter and have become an integral part of everyday production. Today, plasma technology is in the process of fundamentally revolutionising conventional production procedures in industry, as well as applications in the hygiene sector and in medical technology.
Here at Relyon Plasma we have decades of experience in the development and implementation of specialist plasma components for manual and in-line processes.
Relyon Plasma’s plasma products have already been successfully integrated into the following applications:
- Surface activation and functionalization to increase wettability
- Cleaning of metals, glass and plastics
- Preparation for coating processes
- Plasma-assisted adhesive joints and laminating processes
- Optimization of digital and 3D printing
- Improvement of seals
- Plasma-induced reduction of metal surfaces
- Food treatment for quality and longer shelf life
- Sterilization of tissue and surfaces heat-sensitive plastics
- Germ and odour reduction
Advantages of atmospheric pressure plasma
What is the advantage of atmospheric-pressure plasma over low-pressure plasma? Atmospheric plasma systems are much cheaper than low-pressure plasma systems because they do not require expensive vacuum chambers and pumps. In addition, in most cases compressed air is used as process gas, which reduces the need for expensive gases. At the same time it is very versatile – it can be integrated both into batches and into the running conveyor systems. Thus, atmospheric pressure plasma increases production throughput while saving chemical consumables, safety equipment and training.
Different applications – different technologies
According to the different demands that our customers have on us, we have two different technologies in our product portfolio:
Piezoelectric Direct Discharge Technology (PDD Technology®): For sensitive processes requiring cold active plasma.
Pulsed Atmospheric Arc Technology (PAA Technology®): For fast processes that require maximum performance.
