Fluorosurfactant in different fields
Fluorosurfactants are an important class of special surfactants. Fluorinated surfactants are widely used in various fields, including biomedicine, because of their high surface activity, thermal stability and chemical stability. Fire applications, cosmetics, lubricants, paints, polishing and adhesives. For example, in textile production, fluorosurfactants play an important role in the treatment of non-ionic fluorosurfactants on the surface of fabrics, which can form a stable fluorocarbon layer on the surface of the fabric, which can greatly reduce the surface energy of the fabric. , showing properties that are not achieved by general hydrocarbon or silicone finishing, such as water repellency, oil repellency and soil repellency. In addition, in the production of leather, nonionic fluorosurfactants are mainly used as pigment dispersants, water and oil repellent finishes, and emulsifiers in synthetic leather finishes. When it is used as a pigment auxiliary agent and blended and blended with the pigment, the dispersibility of the pigment and the uniformity of the color carrier can be effectively improved, the pigment is not easily agglomerated, and the color becomes more vivid. Nonionic fluorosurfactants have a high surfactant and good self-assembly ability, and are a class of excellent foaming agents. As a foaming agent, non-ionic fluorosurfactant has the advantages of strong sand-carrying ability, easy backflow, less usage, and less damage to the formation. It can be applied to coalbed methane mining.
