The solubilization of oil by surfactant micelles may be an important mechanism for removing a small amount of liquid dirt from the solid surface. Various organic substances insoluble in water are added to different parts of the micelle due to their different properties to form a transparent and stable solution. The non-polar oil is added and dissolved in the non-polar core of the micelle

At present, when the material departments or industrial departments conduct scientific research on inorganic powder, they often use ball milling to obtain inorganic powder with narrow particle size distribution or ultra-fine powder. Crushing itself is also a reversible process. Large particles are crushed into small particles, and small particles can also coalesce to form large particles.

The application of surfactants in the field of nano material preparation has been familiar to everyone, and from another point of view, the development of nanotechnology has entered the stage of "the difficulty is not how to prepare nanoparticles, but how to establish the relationship between macro and micro, and how to apply nano materials", The role of surfactants in the application of nano materials is very important.

Surfactants can be divided into anionic, cationic, amphoteric and non-ionic types according to whether their groups can be ionized and the properties of ionized groups. It is generally composed of nonpolar lipophilic groups and polar hydrophilic groups. The two groups are located at both ends of the molecule to form asymmetric hydrophilic and hydrophobic structures.

In the treatment and recovery of ceramic industry wastewater such as slurry and glaze slurry wastewater, precipitant or flocculant is often added. Its function is opposite to that of dispersant, which can promote the destabilization and aggregation of colloidal system, so as to improve the dehydration of mud and grouting efficiency.

Surfactant can promote the deformation or destruction of the surface by adsorbing on the structural defects on the surface of mineral solid particles. That is, the adsorption of grinding aid molecules on particles reduces the surface free energy of particles or causes dislocation migration of surface lattice, resulting in point defects or line defects, so as to reduce the strength and hardness of particles and promote the generation and expansion of cracks.

Anionic surfactants can also be used to modify at. Jin Yeling and others modified dolomite attapulgite with stearic acid and used it to fill natural rubber and styrene butadiene rubber. The results show that the filling amount of dolomite Attapulgite Modified by stearic acid in the compound is greatly increased, which can reach 110 g / 100 g.

In home decoration, the commonly used kitchen sealant is divided into two types according to its properties: neutral sealant and acid sealant. The places where sealant is generally used in home decoration are: the dumb mouth on the back of wood line, sanitary ware, toilet, cosmetic mirror in the bathroom, the gap between wash basin and wall, etc.

Today's laundry detergent is basically mixed with a variety of surfactants. It's not accurate to say that there is no ionic surfactant at all. In fact, fatty alcohol polyoxyethylene ether sodium sulfate (AES) basically exists. The irritation of AES at low concentration is very weak.

Surfactants can be used for in-situ and ectopic remediation of organic contaminated soil. Ectopic remediation mainly refers to excavating the contaminated soil into an impermeable container, then removing the organic pollutants in the soil with surfactant, and continuously discharging the contaminated liquid from the soil.

Alkyl glycoside, abbreviated as APG, is a biosurfactant synthesized from renewable natural fatty alcohol and glucose. It is a new type of non-ionic surfactant with comprehensive performance. It has the characteristics of ordinary non-ionic and anionic surfactants. It has high surface activity, good ecological safety and compatibility. It is an internationally recognized "green" functional surfactant.

The surface activity of alkyl glycosides is better than other common surfactants. With the increase of alkane chain, the critical micelle concentration decreases and the activity increases significantly. Alkyl glucosides have good foaming power and foam stability. Due to the special hydrophilic group structure and unique oligomer distribution, alkyl glycosides have very good compounding properties.

Alkyl polyglycoside (APG) is a non-ionic surfactant synthesized from renewable plant materials such as fatty alcohol and glucose. Compared with petrochemical raw materials, it is a natural, mild and green product with sustainable development. The application of APG is helpful to the development of tableware detergent in the direction of mild, non-toxic, non irritating, good degradability and strong decontamination.

When the oxide scale is removed from the surface of parts for strong corrosion, various harmful gases are generated in the corrosion process, and acid mist is generated when the gas escapes, which has a great impact on the environment and equipment. If a small amount of OP emulsifier is added to the pickling tank, a layer of foam can be generated on the surface of the pickling solution to prevent the acid mist from escaping.
