An effective method to stabilize a suspension involves the use of additives capable of modulating electrostatic repulsion between particles through a direct action on the electrical double layer.<\/p>

These chemical agents, generally electrolytes, increase the ion concentration in the system, affecting the characteristics of the double layer and helping to stabilize the suspension under specific conditions.<\/p>

The ELECTRICAL DOUBLE LAYER is a structure formed at the interface between a solid phase and a fluid, characterized by a non-uniform distribution of electric charges. It consists of two main areas: an inner layer, where adsorbed ions are bound to the solid surface, and a diffuse layer, composed of free ions distributed in the fluid under the influence of electric and thermal forces.<\/p>

The stabilization of suspensions is due to the electrostatic repulsion generated between particles, which prevents their approach and subsequent aggregation. The double layer plays a crucial role in maintaining particle dispersion and preventing agglomeration by regulating this repulsion through the thickness and density of the charge distribution.<\/p>

The presence of multivalent ions, such as calcium and magnesium, can compress the electrical double layer, reducing its thickness. This leads to a decrease in the repulsive force between particles, favoring aggregation phenomena. When particles come close and form agglomerates, the system may experience an increase in viscosity or become unstable.<\/p>","protected":false},"excerpt":{"rendered":"
