Main components of dispersant

Dispersant is a chemical substance used to disperse solid particles or suspended solids, and its main components can include the following categories:

Polymer dispersant: Polymer dispersant is one of the most common dispersants, commonly used polymers include polyacrylamide (PAA), polyvinyl pyrrolidone (PVP), polystyrene acid (PSA), etc. These polymer dispersants have the function of adsorbing on the surface of particles, forming a charge barrier to prevent mutual attraction between particles, thereby dispersing particles in water.

Surfactants: Surfactants are also widely used as dispersants, including non ionic surfactants, anionic surfactants, cationic surfactants, etc. These surfactants can reduce the surface tension of the liquid, maintain a charged state on the surface of particles, and thus prevent aggregation and precipitation between particles.

Polymer: In addition to polymer dispersants paa, other types of polymer can also be used as dispersants, such as carboxymethyl cellulose (CMC), chitosan (Chitosan), etc. These polymers can form colloidal solutions in water, which adsorb and coat the surface of particles to achieve uniform particle dispersion.

Inorganic salts: Some inorganic salts can also be used as dispersants, such as phosphates, silicates, etc. These inorganic salts alter the charge characteristics of particles through adsorption reactions with their surfaces, thereby preventing mutual attraction between particles.

Suitable dispersants need to be selected based on the specific application and particle characteristics, and relevant product instructions and operating instructions should be followed during use.
