adhesion

Examples of adhesion in the following topics:

• Capillary Action

  • On the other hand, when intermolecular forces occur between different types of molecules (especially when they are part of different phases of matter), they are referred to as adhesive forces, or resulting in adhesion.
  • It occurs when the intermolecular attractive forces between the liquid and the solid surrounding surfaces (adhesive forces) are stronger than the cohesive forces within the liquid.
  • If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container act together to lift the liquid.
  • A convex meniscus occurs when the molecules have a stronger attraction to each other (cohesion) than to the material of the container (adhesion), causing the surface of the liquid to cave downward.
  • The curvature of the surface at the top of a column of fluid in a narrow tube is caused by the relative strength of the forces responsible for the surface tension of the fluid (cohesive forces) and the adhesive forces to the walls of the container.

• Polymers

  • Indeed, applications of these materials as fibers, flexible films, adhesives, resistant paints and tough but light solids have transformed modern society.

• Regio and Stereoisomerization in Macromolecules

  • Thus, atactic polypropylene is useless as a solid construction material, and is employed mainly as a component of adhesives or as a soft matrix for composite materials.

• The Age of Plastics

  • Many modern adhesives involve the formation of a plastic bonding substance.

• Indoor Pollution: Formaldehyde

  • Formaldehyde is frequently used in adhesives and as a strengthening agent in paper products like facial tissues.

• Characteristics of Condensation Polymers

  • Step-growth polymerization is also used for preparing a class of adhesives and amorphous solids called epoxy resins.

• Chemical Manufacturing

  • Products include electronic chemicals, industrial gases, adhesives and sealants as well as coatings, industrial and institutional cleaning chemicals, and catalysts.

• Empirical Formulas

  • Suppose you are given a compound such as methyl acetate, a solvent commonly used in paints, inks, and adhesives.

• Types of Synthetic Organic Polymers

  • Similarly, thermosets similarly become hard and cannot change shape once they have set; for this reason, they are often used in adhesives.
