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 commonly used modification methods are: (1) physical-chemical adsorption modification with stearic acid; (2) Its surface was modified by titanate, aluminate and other coupling agents; (3) Alkyl phenolic resin and nitrile rubber were used to modify its surface in situ.

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.

Glyphosate itself is a low toxicity pesticide, which will be fully biodegradable in the natural environment soon after being absorbed by the soil. The current research believes that it will not harm the environment. However, fatty amines are highly toxic to aquatic fish and mammals and difficult to biodegrade, so its safety has been questioned more and more.

Alkyl glycosides can be completely biodegradable, non-toxic and harmless to the environment. As a surfactant, they can strengthen the dissolution and hydrolysis of organic waste, accelerate the process of anaerobic decomposition of waste, and can be applied in the industrial process of anaerobic decomposition and treatment of waste.

Alkyl polyglycosides (APG) is a new type of non-ionic biosurfactant. Its raw materials come from renewable plants, such as corn, coconut oil, palm kernel oil and so on. APG does not contain K + and Na + plasma and can be completely degraded into H2O and CO2 within 7 days. As an environment-friendly surfactant, APG can promote the dissolution and hydrolysis of organic matter in waste, so as to reduce the time of AD process.

Alkyl glucosides have the advantages of ordinary nonionic and anionic surfactants: high surface activity, high viscosity, rich foam, fine and stable.

When the pH of alkyl glycoside leaching solution was 5.2 and the concentration was 85 g / L, the removal rates of CD, Cu, Pb and Zn in soil reached 77.7%, 40.5%, 24.5% and 20.0% respectively.

The main film forming materials in emulsion coatings are usually polymer emulsions, synthetic resin emulsions prepared by emulsion polymerization, or emulsified polymer resin emulsions produced by post emulsification process, and emulsifiers play an important role in them.

The basic feature of surfactants is that they can significantly reduce the surface tension of solvents. Generally, alkyl glycosides with alkyl carbon chain length greater than 8 carbons have surface activity and critical micelle concentration (CMC).

Application of liquid hand soap: many people feel that the liquid is not viscous enough after dissolving the soap. For soap makers who advocate nature, it is a big problem to find a non-toxic, harmless and efficient thickener. Alkyl glycosides can definitely satisfy soap makers in terms of safety, because AGP is indispensable in many children's shampoos and shower gels.

Surfactants are often used in industrial industries. For the use of surfactants, most of them are used in washing and textile industries. For all fine industrial industries, they can not leave the use of surfactants. All industries related to our industry, including the pharmaceutical industry, are also inseparable from the use of surfactants, as well as the paper industry, which is also a field of fine industry. Surfactants are also widely used in the paper industry.

Surfactant can reduce the interfacial tension and reduce the wetting angle θ Close to zero, the solid powder can be spontaneously dispersed in the surfactant solution. At the same time, the surfactant can help the liquid to wet the inner surface of the solid, make the liquid penetrate into the channels and voids between the aggregates inside the particles, provide a certain pressure, and destroy the strengthening bond force of the particle aggregates under the action of machinery.

Alkyl glycosides, as a multifunctional treatment agent, can be selected and used according to different needs of drilling fluid. Alkyl glycosides with different structures can not only inhibit sloughing, lubrication and environmental protection, but also improve the solid capacity of drilling fluid and the temperature resistance of polymers in drilling fluid. They can also be used as viscosity reducer and fluid loss reducer of conventional drilling fluid, dispersant and retarder of cement slurry, emulsifier of oil in water drilling fluid and foaming agent of microbubble system.

Alkyl glycoside (APG) has excellent ecological and toxicological properties and outstanding physical and chemical properties. It is especially suitable for washing products and personal care products in contact with human skin. In addition, it can be used as functional additives in daily chemical industry, pharmaceutical industry, industrial emulsifier, food industry, biochemical industry and agricultural chemicals.

The application principle of surfactant in water-based metal cleaning agent is to weaken or offset the adhesion of oil on the metal surface through the wetting, penetration, emulsification, dispersion and solubilization of surfactant, and accelerate the oil to separate from the metal surface and enter the washing solution by mechanical and physical methods to be emulsified, dispersed and suspended or solubilized micelles.
