Comparative advantages of hyperdispersants and dispersants

Super dispersants are a new and efficient type of polymer based dispersant, which overcome the limitations of traditional dispersants in terms of molecular structure.

Super dispersant, also known as polymer dispersant, is an efficient polymer dispersant with a molecular weight between 1000 and 10000.

Compared with traditional surface treatment agents and dispersants, it has the following advantages: ① Super dispersants use anchoring groups instead of hydrophilic groups on surface modifiers, making adsorption irreversible and difficult to desorb; ② Replacing the lipophilic groups on surface modifiers with polymer solvation chains, with adjustable chain length, can effectively stabilize the space It can form extremely weak and easily mobile micelles, which can quickly move towards the surface of particles and provide wetting protection. Therefore, hyperdispersants are widely used in pigment dispersants, concrete additives, ceramic dispersants, coal water slurry, drilling mud, cosmetics, food additives, pharmaceuticals, biotechnology and other fields. So the advantages of super dispersants compared to dispersants are more obvious, but opinions vary. Using super dispersants does not necessarily mean they are better than dispersants. Different products require different additives. Compared to dispersants, super dispersants have a polymer structure, higher prices, higher technical barriers, and different application levels. So as long as we are clear about the application of additives in product selection, we need to understand the advantages of super dispersants!
