Dispersant is an interfacial active agent with two opposite properties of lipophilicity and hydrophilicity within the molecule.
Dispersion refers to the mixture formed by the dispersion of one substance (or several substances) into another substance in the form of particles.
Dispersants can uniformly disperse the solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, and also prevent the sedimentation and condensation of particles, forming amphiphilic reagents required for stable suspensions. Houhuan chemical R & D and production of water-based additives and oil-based additives in various industries, related surfactant categories.
The dispersion system is divided into: solution, colloid and suspension (emulsion). For solution, solute is a dispersant and solvent is a dispersant. For example, in NaCl solution, the dispersant is NaCl, and the dispersant is water. The dispersant refers to the material dispersed into particles in the dispersion system. Another substance is called dispersed substance.
The functions of using industrial pigment dispersant are as follows:
1. Use wetting dispersant to reduce the time and energy required to complete the dispersion process, stabilize the dispersed pigment dispersion, PP adhesion promoter, modify the surface properties of pigment particles, and adjust the mobility of pigment particles.
2. Reduce the interfacial tension between liquid-liquid and solid-liquid. Dispersants are also surfactants. Dispersants are anionic, cationic, non-ionic, amphoteric and polymeric. Among them, anionic type is used most.
3. Dispersant an auxiliary agent that can improve the dispersibility of solid or liquid materials.
