The action mechanism of dispersants can be summarized as steric hindrance and electrostatic stabilization. Dispersants have a great characteristic in molecular structure, namely “amphiphilicity”, hydrophilicity and lipophilicity. The lipophilic group of traditional dispersants is generally a hydrocarbon chain structure, and …

Application examples of dispersants
The detergents used in washing clothes and dishes in daily life are typical dispersants. Detergents disperse stains in water by stripping and coating them, thus achieving the purpose of washing. In scientific research, dispersants are added before the reaction to …

Dispersant Design
When designing a dispersant for sludge/varnish control and high temperature deposit inhibition, the process usually begins with the selection of the polymer tail, which is responsible for maintaining oil solubility. The most commonly used polymer is polyisobutylene (PIB), which is …

The role of dispersants
The role of dispersants is to use wetting dispersants to reduce the time and energy required to complete the dispersion process, stabilize the dispersed pigment dispersion, modify the surface properties of pigment particles, and adjust the mobility of pigment particles. …

Molecular structure characteristics and surface adsorption mechanism of dispersants
Polymer dispersants maintain the performance of pigment particles in the medium through electrostatic repulsion and steric hindrance. In order to make the dispersion system uniform and stable and meet the performance requirements, the molecular structure of the polymer dispersant adsorbed …

Dispersion mechanism of dispersants
1、 Electrostatic repulsion theoryPigment particles in aqueous dispersions and even in oily dispersions are charged for different reasons. Since the particles are charged, an equal amount of countercharge will inevitably be adsorbed around their interface to form a double layer …

Do you know the structural principle of water-based dispersants?
Dispersant is an amphiphilic chemical that can increase the compatibility of oily and aqueous components in the same system. Dispersants are additives that can enhance and improve the dispersibility of solid or liquid materials. With the development of today’s society, …

Let you know the performance characteristics of water-based dispersants
Dispersant is a surfactant with two opposite properties, lipophilicity and hydrophilicity, in the molecule. It can evenly disperse the solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, and at the same time …

Don’t know about waterborne coating dispersants?
Dispersants are used to disperse various powders in solvents in a reasonable manner, and to stably suspend various solids in solvents (or dispersions) through certain charge repulsion principles or polymer steric hindrance effects. Aqueous dispersants are surfactants that have both …

Small papermaking dispersant, a force that cannot be underestimated
The principle of dispersant is to distribute solid tiny particles as evenly as possible in another incompatible material. It refers to a coarse dispersion system composed of insoluble particles distributed in the outer phase of liquid or semi-solid. Dispersant can …
