Fluorinated surfactants refer to surfactants in which all or part of the hydrogen atoms in the carbon hydrogen chain are replaced by fluorine atoms.
Characteristic
High surface activity: Fluorinated surfactants have extremely low surface tension and can significantly reduce the surface tension of liquids at very low concentrations. For example, in some industrial applications that require rapid spreading and wetting, such as in the formulation of coatings and inks, fluorinated surfactants can enable coatings or inks to spread rapidly on the substrate, forming a uniform coating.
Good chemical stability: It has high tolerance to strong acids, strong bases, strong oxidants, etc. In some special chemical environments, such as in electroplating solutions, fluorinated surfactants can exist stably under strong acidic and oxidizing conditions, playing a role in improving the electroplating effect.
High thermal stability: able to maintain its surface activity performance at high temperatures. In high-temperature industrial processing, such as high-temperature printing and dyeing processes, fluorinated surfactants can effectively exert their wetting, emulsifying, and other functions.
Application Area
Fire protection field: used for preparing efficient fire extinguishing agents. Fluorinated surfactants can reduce the surface tension of water, allowing fire extinguishing agents to better spread on the surface of combustibles and improve fire extinguishing efficiency.
Textile industry: widely used in waterproof, oil resistant, and stain resistant finishing of fabrics. Fluorinated surfactants can form a low surface energy film on the surface of fabrics, giving them water repellent, oil repellent, and stain resistant properties.
Electronic industry: During the cleaning process of electronic components, fluorinated surfactants can effectively remove oil and impurities from the surface of electronic components, and due to their good chemical stability, they will not cause corrosion to electronic components.
