Dispersion is a process by which (in the case of solid dispersing in a liquid) agglomerated particles are separated from each other, and a new interface between the inner surface of the liquid dispersion medium and the surface of the dispersed particles is generated. This process is facilitated by molecular diffusion and convection. With respect to molecular diffusion, dispersion occurs as a result of an unequal concentration o… WebAEROSOL Fiche de Données de Sécurité conformément à la Loi sur les produits dangereux (11 février 2015) Date d'émission: 09-02-2024 Version: 1.0 07-27-2024 FR (français) Page 1 RUBRIQUE 1: Identification 1.1.
