There are many advantages to using Plasmatreat’s Openair-Plasma® surface technology. The main advantage is the enormously high efficacy when compared to other methods for the activation of surfaces. The Plasmatreat Openair-Plasma® surface treatment technology simply results in better and more durable surface activation. Plasmatreat’s Openair-Plasma® systems are also very easy to integrate into existing production lines, they are environmentally friendly, space-saving and have low operating costs.
Public current (230V/400V) as well as a compressed-air supply are sufficient. An extraction system is also required.
The result of the surface treatment depends on the speed of the passing material, on the effective distance of the nozzle end, and on the width of the treatment area. Partially, processing speeds of up to 400 m/min can be reached. When treating EPDM-/ TPE sections, e.g., the speeds run are about 2 to 30 m/min.
Plasmatreat has demonstrated in many user operations that its Openair-Plasma® technology can provide superior surface treatments as activation and cleaning than the use of solvents and, in many cases, allow users to completely abandon the use of environmentally damaging substances such as benzene or acetone.
Normally it is extremely difficult to pre-treat composites because of the differing electrical and thermal conductivities. In the Plasmatreat Openair® atmospheric plasma process, low temperature plasma is applied to the material to be activated allowing superior surface treatment without any negative effects on composite materials.
Plasmatreat’s plasma systems and nozzles require very little space and are easily installed into existing production lines. We can easily adapt our pre-treatment stations (plasma nozzles within a protective covering with extraction) to your individual manufacturing conditions.
The only operation expenses will result from the electricity and compressed-air consumption, and the ordinary maintenance costs. No costly operating supplies or other consumables are needed.
Plasma is much cooler than other combustion flames (about 300°C). With most applications, the temperature of the moving material increases by about 15 °C. The process is cool enough that even fingernails can be treated using Plasmatreat’s Openair-Plasma® method.
No ozone is released during the plasma pre-treatment. Nitrogen oxides and monoxides can be produced when certain materials are pre-treated. For this reason complete Plasmatreat Openair® plasma surface treatment systems incorporate an extraction system to remove any such emissions.
You need nothing other than electrical energy and oil-free compressed air. If you do not have a separate compressed-air supply, we can provide the systems with low-pressure side channel compressors for you.
There is a risk of electric shock directly inside the plasma flame. The nozzles themselves are grounded and therefore can be directed by hand without risk of electrical shock.
The length of time that the activation effect will last will vary depending on the material activated. The effect is strongest directly after the treatment, then fades gradually and settles at a level higher than before pre-treatment. Under ideal circumstances production steps such as coating or painting should be carried out directly after the pre-treatment. However, activation by Openair-Plasma® shows an extreme long-time stability in comparison to other pre-treatment methods. We would be pleased to discuss with you in detail how the activation effect will work in your particular application.
About 1 to 2 cm. The necessary adjustments to achieve the proper distance are very simple and their use in the production process is uncomplicated. The components are not subject to mechanical wear and tear.
Plasmatreat’s Openair-Plasma® flames infiltrate into grooves and small areas. The pre-treatment effect is even intensified in corners. Thus, you can effectively pre-treat plane surfaces as well as complicated shapes.
This process is a plasma surface treatment method where ions react with the material‘s surface. It does not change the mass in any way.
