A dispersant is a chemical substance that can disperse precipitates or particles in a liquid to prevent them from re settling at the bottom. Different types of dispersants are suitable for different substances and applications. The following are common types of dispersants:
Polymer dispersants: including anionic polymers and cationic polymers, with high molecular weight and good dispersion effects. Polymer dispersants are commonly used to disperse solid materials such as pigments, fillers, and ceramics.
Surfactant dispersant: It belongs to a polymer with a dual affinity of oil and water in chemistry, which can promote particle dispersion. Surfactant dispersants are typically used to disperse liquid substances such as paints and dyes.
Organic acid salt dispersants include citric acid, oxalic acid, and lactic acid, which can form complexes with metal ions and form stable solutions in water. Organic acid salt dispersants are commonly used to disperse metal ions and salts.
Silicate dispersant: With high specific surface area and active surface, it can disperse particles into liquids and form stable dispersed states on the liquid surface. Silicate dispersants are commonly used to disperse pigments, slurries, and cellulose.
It should be noted that there are various types of dispersants, and different dispersants have different applicability and effects in different application fields and processes. Choosing the correct dispersant can improve product performance and production efficiency.
