| Résumé : |
Foam problems during production and application of waterborne systems are common. The reasons for the generation and stabilization of foam, and the types of foam in these systems, have been the subject of numerous discussions. Foam is generated and stabilized by the presence of surfactants commonly found in small concentrations (e.g., wetting agents and polymer emulsifiers). Destabilization of foam is achieved through the addition of substances which orient themselves at the air/liquid interface, resulting in a reduction of surface tension. This paper discusses the different types of foam, the phenomenon of foam generation, and the physical and chemical aspects of the technology and substances available to destabilize foam successfully. |
