Phosphate dispersants are highly effective chemical additives that are mainly used in industrial cleaning processes to improve cleaning efficiency and reduce cleaning costs. Through their special chemical structure, they can disperse and suspend dirt particles, preventing them from redepositing on …

Mechanism of action of dispersants

No Comments

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 …
