In addition to the above-mentioned main uses, fluorine-containing surfactants are used as industrial monosodium glutamate, which can be said to be used in various fields of industry. Domestically, there are cultural relics protection, electroplating, pigments, coatings and inks, sealing and solid propellants for the aerospace industry. Wait. In fact, the application of fluorine-containing surfactants is far more than the above-mentioned fields. It has already been applied in many fields abroad. Due to the high price, it has not been applied in our country. Such as metal surface treatment agents, fluxes for electronic components, glass ceramic industrial cleaning agents, additives, water and oil repellent and antifouling treatment agents, photosensitive film coating additives, photosensitive emulsion emulsifiers and defoamers, high-grade concrete additives and asbestos Wetting agent, leather waterproof, oil, and antifouling treatment agent, protein foam fire extinguishing agent and light water foam fire extinguishing agent additives for fire fighting, blood substitute emulsifiers, pesticides and herbicide additives, daikin ptfe powder etc.
Adding a small amount of fluorocarbon surfactants in the coating industry can improve the leveling of the paint and increase the smoothness of the coating. With the improvement of people’s living standards, the application of fluorocarbon surfactants in coatings is becoming more and more. Wider. This chapter will give a brief introduction to the basic characteristics of fluorocarbon surfactants, the basic properties of aqueous and non-aqueous solutions, and the relationship between structure and surface activity, so that readers can use these knowledge to better choose fluorocarbons in actual work. Surfactant.
Classification and performance of fluorocarbon surfactants
The classification of fluorocarbon surfactants is the same as that of general surfactants, and there are many ways to classify fluorocarbon surfactants. According to the different polar groups in fluorocarbon surfactants, they are divided into two categories: ionic and non-ionic. Ionic surfactants can be divided into three categories: anionic, cationic and zwitterionic. A brief introduction to them is given below.
