Plasma à pression atmosphériqueUn plasma à pression atmosphérique (ou plasma à PA ou plasma froid) est le nom donné à une catégorie spéciale de plasma pour lequel la pression approche celle de l’atmosphère.
Le plasma à pression atmosphérique marque une nette différence avec le plasma basse et haute pression. En effet, contrairement à ces derniers aucune enceinte de traitement n'est nécessaire. Ce type de plasma peut donc être utilisé directement sur ligne de production, évitant ainsi l'utilisation de vide qui est extrêmement onéreuse.

| Résumé : |
The use of recyclates confronts companies with new requirements in the processing, bonding, printing and labeling of materials and components. Atmospheric plasma technology, in which Plasmatreat GmbH has specialized, has established itself as a key technology: it often makes the use of recycled plastics possible in the first place – and also proves to be the means of choice on the way to more environmentally friendly, more resource-efficient production processes. |
| Note de contenu : |
- Flawless, long-lasting UV digital printing on recycling cups
- Solid connection in 3D printing of metal and recycled plastic
- The automotive industry relies on dashboards with recycled content
- More environmentally friendly processes and raw material saving
- Plasma technology drives sustainable development
- Fig. 1 : The injection-molded recycling cup is treated with openair-plasma to increase the surface energy of the non-polar plastic
- Fig. 2 : A high surface energy is decisive for the wetting of the printing ink in UV digital printing and creates the prerequisite for good adhesion of the solvent-free printing inks
- Fig. 3 : Thanks to the adhesive layer, which is applied to the metal carrier using the PlasmaPlus process, the pen holder made of carbon fiber-reinforced, bio-based polyamide holds on to the surface
- Fig. 4 : The pretreatment with plasma makes non-polar plastics susceptible to adhesion processes and ensures a firm connection of the different, sometimes even incompatible materials, for example when laminating dashboards made of recycled materials with powder-sintered molded skins made of soft plastic |
