Differentians are chemicals that can evenly disperse solid particles in liquid. They are widely used in many fields, mainly playing the following functions:
Dispels: Differentians can reduce the mutual attractiveness between solid particles and make it discrete and dispersed in liquid. By acting with the surface of the particles, the dispersant can prevent the aggregation and precipitation between the particles, and maintain the uniform dispersing state of the particles.
Stability: Differentians can increase the stability of the decentralized system. They form a stable layer of decentralized dispensel siege particles by wrap the surface of the particles or change the surface charge characteristics of the particles to prevent the particles from re -converging and precipitated.
Improving liquidity: Disted agents can reduce friction between particles and improve the liquidity of the system. This is of great significance for powder, slurry and granular suspension, and can improve process performance and production efficiency.
Control particle size and particle size distribution: Differentians can control the size and distribution of solid particles. By adjusting the type and concentration of the dispersant, the particle size and particle size can be achieved, thereby meeting the requirements of specific applications.
Improve the surface activity: Some dispersagas have the nature of the surfactant, which can change the tension and nature of the liquid-solid interface. This can provide good wetability and adhesion for coatings, inks, etc. in applications that need to be in contact with solid particles.
It should be noted that different types of dispersers are suitable for different systems and particles. When selecting and using a dispersant, according to the specific application requirements and system characteristics, the appropriate dispersant should be selected and follows the correct usage methods.
