Abstract
En la presente Tesis Doctoral se ha llevado a cabo un estudio de viabilidad para la
sustitución de procesos tradicionales utilizados hoy en día en la industria de los
electrodomésticos, como son el desengrase superficial o etapas de imprimación, por la
tecnología de plasma. El objetivo es obtener una mejora en las propiedades adhesivas de
las superficies tratadas.
Para ello, se evalúan y se seleccionan las condiciones óptimas del tratamiento de
plasma en función del proceso tecnológico a sustituir. Los parámetros a optimizar en el
proceso de plasma influyen en la intensidad del tratamiento. Asimismo, se estudia la
recuperación hidrofóbica de las superficies, determinándose así el tiempo de activación
de las mismas tras el tratamiento, esencial para poder definir tiempos de transporte y/o
almacenaje antes de la realización de procesos posteriores.
Los resultados obtenidos concluyen la posibilidad de la sustitución de los
procesos tradicionales por la tecnología de plasma, logrando tanto uniones adhesivas
con la misma o mejor resistencia adhesiva en comparación a los procesos actuales como
beneficios en ámbito económico, tecnológico, ambiental y sanitario. ---------------------------
This PhD Thesis carries out a viability study in order to replace existing processes in use nowadays at home appliances industries, as surface degrease treatment or primer steps by means of plasma technology. Our objective is to improve adhesion properties into the treated surfaces. In order to reach our objective, optimal treatment conditions have been evaluated and selected according to the concrete replaced industrial process. The parameters under study are: time exposure and sample-to-torch distance. Likewise, hydrophobic recovery is studied, in order to establish the activation period of the surfaces, which is an essential factor in determining the possibility of transport or storage of the samples after treatment. Results show possible replacement of current processes by the plasma technology, achieving adhesive bonding with similar or even better strength than classic ones and also economical, technological, environmental and healthy benefits.
