| Résumé : |
Adhesives, any substance that is capable of holding materials together in a functional manner by surface attachment that resists separation. "Adhesive" as a general term includes cement, mucilage, glue, and paste—terms that are often used interchangeably for any organic material that forms an adhesive bond.
To ensure adhesion, the adhesive must wet the surface of the adherend. The first basic rule of adhesion is that the adhesive must wet the surface. Second, upon solidification, the adhesive must not, develop internai of residual stress sufficient to disrupt the bond. Solidification generally causes a contraction or shrinkage of the adhesive. If this contraction causes internat stress in the adhesive equal to its tensile strength, an outside force in a similar direction will cause rupture of the joint within the adhesive.
Adhesion is the force of intermolecular attraction evidenced in the phenomena of wetting wherein molecules of adhesive are more attractedto molecules of adherend than to each other. When surfaces are held together by interfacial forces, they are said to show good adhesion. Good adhesion requires very close contact. ln the case of adhesive bonding this is achieved by flow of the adhesive and wetting of the substrate. Adhesion strength is the force required to pull the adhesive clearly from the surface.
This article focuses on adhesives, exploring the various classifications and categories available and explaining their respective characteristics, advantages, and disadvantages. |
