WebA dispersion is a system in which distributed particles of one material are dispersed in a continuous phase of another material. The two phases may be in the same or different states of matter . Dispersions are classified in a number of different ways, including how large the particles are in relation to the particles of the continuous phase ... Web¾A stable colloidal system is one in which the particles resist flocculation or aggregation and exhibits a long shelf-life. ¾Depends upon the balance of the repulsive and attractive forces that exist between particles as they approach one another. ¾If all the particles have a mutual repulsion then the dispersion will remain stable.
Webcolloidal suspensions and association colloids. In certain circumstances, the particles in a dispersion may adhere to one another and form aggregates of successively increasing size, which may settle out under the influence of gravity. An initially formed aggregate is called a floc and the process of its formation flocculation. WebCoaxial mixers have shown a uniform energy dissipation rate throughout the mixing tank and a high mass transfer rate. However, to the best of our knowledge no investigation …
