Diszperzánsok

Diszperzánsok, also known as dispersants or dispersing agents, are chemical additives used to promote the separation of particles in a liquid medium and prevent them from aggregating or settling. They are crucial in many industrial processes and product formulations where a stable dispersion is required. Dispersants work by adsorbing onto the surface of particles, imparting either electrostatic or steric repulsion between them. Electrostatic dispersants create a charge on the particle surface, causing particles to repel each other due to like charges. Steric dispersants, on the other hand, form a physical barrier around the particles, preventing them from coming into close contact and agglomerating. The choice of dispersant depends on the nature of the particles, the liquid medium, and the desired stability and properties of the final dispersion. They are widely employed in industries such as paints and coatings, ceramics, pharmaceuticals, agriculture, and in the processing of pigments, fillers, and other solid materials. The effectiveness of a dispersant is often measured by its ability to reduce viscosity, improve pigment strength, and enhance the shelf life of the product.
