The surfactant can be liquid or solid. Depending on the different chemical structure and physical properties, the surfactant can exist in liquid or solid forms.
Some common liquid surface active agents include: anion surfactants (such as sulfate, sulfate, sulfonate, carboxylic acid salt, etc.), cationic surfactant (such as ductinium salt), non -ionic surfactants (such as polyether, polyetric, polyetry Ethylene alcohol, etc.) and bisexual surfactants (such as sodium dulate sulfate, etc.).
Some solid surfactants include: adsorbents (such as silicone, activated carbon, etc.), solid collagen (such as silicon, colloid titanium dioxide, etc.) and nanomaterials (such as nanohide, nano -zinc oxide, etc.). These solid surfactants usually exist in the form of powder or particles.
Different surfactants play an important role in different application areas. Line surfactants are often used in the fields of detergents, emulsifiers, foam agents and other fields, while solid surfactants are often used in catalysts, adsorbents, lubricants, etc. field.
Surface active agent is a substance that can reduce the surface tension of liquid and improve the moisture performance of the liquid. They are composed of molecules with hydrophilic and hydrophobic properties, one part interacts with water, and the other parts interacts with non -polar matter. This characteristic allows the surfactant to form a film on the surface of the liquid and change the nature of the liquid and solid surface contact. Surface active agents are widely used in detergents, emulsifiers, foaming agents, moisturizers and other fields.
