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.

When surfactants are adsorbed on the metal surface, their hydrophilic groups are adsorbed on the metal surface. Due to the different properties of hydrophilic groups, they are physically or chemically adsorbed on the metal surface. The adsorption of different surfactants on the metal surface follows different adsorption isotherms.

Reactive flame retardants participate in the polymerization reaction as a monomer, so the polymer itself contains flame retardant components. Its advantage is that it has little impact on the service performance of polymer materials and has long flame retardancy.

Alkyl glycosides have good surface and interface properties. APG is a moisture-absorbing solid, which is generally dissolved in water and difficult to dissolve in some common organic solvents. However, it has good solubility and surface activity in acid solution, and its solubility and surface activity in alkali solution are more prominent than other non-ionic surfactants. When in use, it can be prepared into a stable inorganic salt active solution with a concentration of 20% ~ 30%.

Using the green non-ionic surfactant alkyl glycoside as the main raw material and deionized water as the solvent, a new type of green clothing cleaning wipes with excellent decontamination effect and friendly to the environment was developed. The properties of surface tension, stability and decontamination when compounded with other surfactants were investigated.

Due to the different flame retardant mechanism of various flame retardants, it is difficult to achieve the ideal effect by using a single flame retardant. Composite flame retardants are usually used.

The impact of surfactants on food safety can mainly include two aspects. On the one hand, surfactants themselves are enriched in animals and plants, and show their own toxicity with the accumulation of food chain in human body; On the other hand, the existence of surfactants accelerates the absorption of other toxic substances by plants, resulting in harm to food safety production.

Firstly, it comes from renewable plant resources, which is conducive to the protection and saving of limited resources. Secondly, the products made from it can be 100% biodegradable in the environment and re-enter the natural cycle. The biodegradability test shows that this degradation process is fast and complete. According to the internationally recognized OECD Test method, all tests show that APG has excellent primary biodegradability and final biodegradability. Alkyl glycosides do not harm the environment under all environmental conditions and have excellent environmental compatibility.

What are the advantages of surfactant synergistic repair technology? Surfactant synergistic remediation technology has become a very potential remediation technology of organic soil pollution. It mainly uses the solubilization of hydrophobic organic pollutants by surfactant solution to promote the desorption and dissolution of organic pollutants adsorbed on soil particles, and finally move out of the soil environment, so that the soil can be repaired. In the technology of bioremediation of contaminated soil, adding an appropriate amount of surfactant when necessary can disperse microorganisms and promote growth.

In the preparation process of down jacket cleaning wipes, the effects of different ratios on the performance of wipes were observed. Combined with the use feeling and decontamination effect of wipes, it was considered that formula 5 was better when the mass fraction of green non-ionic surfactant alkyl glycoside (APG) was 12%, the mass fraction of surfactant AEO-9 was 5%, and the mass fraction of SCA was 3%.
