Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

| Résumé : |
A selection of surfaces relevant to PSAs was characterized by several analytical tools to understand what substrate properties can affect peel. In some cases, such as steel and HDPE panels, the surface chemistry of the substrate is the dominant influence to adhesive performance. In the case of corrugated cardboard, the surface roughness and fiber integrity were critical to adhesion. Comprehensive analysis of the surface chemistry and roughness of the substrate can lead to ideal PSA selection, as well as aid in troubleshooting for any system showing less-than-ideal adhesion.
The data presented in this study also illustrate the importance of considering both the adhesion data and the analytical data simultaneously to determine the factors most important for a given adhesive/substrate system. For example, the surface roughness of the bottles varies, but does not vary systematically with the peel data. But, the surface chemistry of the flame treated bottle (high O and surface polarity) indicates why peel is high. Similarly, both the surface chemistry of the substrate and surface roughness can be investigated to guide troubleshooting where the adhesion is not at the desired level. Lastly, there are specific substrate and adhesive combinations that end users define as key for qualifying adhesives. This study demonstrates that the selection of substrate surfaces has a major impact in determining if a given adhesive meets performance targets. |
