The application principle of surfactant in water-based metal cleaning agent is to weaken or offset the adhesion of oil on metal surface by the properties of wetting, permeation, emulsification, dispersion and solubilization of surfactant. The oil is emulsified into the washing solution by mechanical and physical methods, and then it is suspended or solubilized in micelles.

Alkyl glucosides have the advantages of ordinary nonionic and anionic surfactants: high surface activity, high viscosity, rich foam, fine and stable. The results showed that the combination with other surfactants had obvious synergistic effect; It has strong dispersing ability to calcium soap, and can be used in hard water; The stimulation to epidermis, mucosa and living cells is very low; It is easy to be biodegraded in natural environment and less pollution. APG is made from starch or hydrolyzed sugar and fatty alcohol. Its raw material is very wide, and more and more attention has been paid to APG in recent years.

The solubilization of surfactant makes oxygen molecules supersaturated in water solution, which is equivalent to increasing the saturation solubility of oxygen in water. The saturated solubility of oxygen in aquaculture water is not more than 9mg / L. when surfactant is added to the aquaculture water, the saturation solubility of oxygen in the aquaculture water can be increased.

Alkyl polyglycosides in the cosmetics industry, solvent mainly used in cosmetics, hair oil, hair and other products. Due to the differences in structure and polarity of oily components in cosmetics, the mechanism of solubilization is also different.

The dilute solution of surfactant obeys the law of ideal solution. The adsorption capacity of surfactants on the surface of the solution increases with the increase of the concentration of the solution. When the concentration reaches or exceeds a certain value, the adsorption amount will no longer increase. These excess surfactants molecules are disordered or exist in a regular way. Both practice and theory show that they form a connective complex in a solution, which is called micelles.

With the maturity of the market, printing and dyeing auxiliaries are also mature, and the high-quality auxiliaries of various manufacturers are gradually recognized by the industry. We are glad to see that more and more printing and dyeing enterprises begin to choose qualified suppliers, and more and more auxiliary manufacturers are moving towards the market on the basis of qualification.

"Printing and dyeing wastewater treatment technology policy" is formulated based on long-term engineering practice and the evolution of textile printing and dyeing wastewater quality. The key point is that the concentration of printing and dyeing wastewater is not very high, so the first stage of anaerobic process, namely anaerobic hydrolysis and aerobic biological treatment process, is adopted.

Surfactants have been widely used in synthetic fiber oil industry, and will be widely used with new varieties and continuous improvement of performance. But we should also see that there are many problems in the domestic practical application, such as the instability of product quality brings difficulties in oil agent deployment and unstable quality of oil agent; The monotony of surfactant makes it difficult to select the oil blending agent.

Surfactant can reduce the interfacial tension and make the wetting angle θ Near zero, the solid powder can be dispersed spontaneously in surfactant solution. Meanwhile, surfactant can help liquid wet the inner surface of solid, make liquid penetrate into the channel and void between the particles' internal aggregates, provide certain pressure, and under the action of mechanical force, the reinforcement bond force of particle aggregation will be destroyed. At the same time, surfactant can help grind, reduce the surface energy of particles, prevent the surface of damaged surface from bonding, and thus achieve the purpose of preventing particle aggregation.

Phosphorus fabric flame retardant is a kind of flame retardant with rich resources, low wood forming and wide application. It has the advantages of colorless, transparent, high efficiency, low toxicity, wide use and low cost. It can be used in PU foam plastics, UP, EP and other fields. Due to its dual functions of flame retardant and plasticizing, the fire retardant of phosphorus based fabrics has been paid attention to, including phosphate, halophosphate, compound phosphate and its derivatives, polyphosphate and red phosphorus.

Compared with ionic surfactants, nonionic surfactants have less foam generation and are less stable. Some surfactants are easily soluble in water and can't reduce the surface tension below 30dyne / cm. For example, alkyne glycol system, organic silicon system (Tegopren) and fluorine (perfluorooctanoate) surfactant are very water-soluble and can reduce surface tension to below 25dyne/cm. They are all effective defoamers. The mechanism of defoaming is to replace the foaming surface film produced by easily foaming surface active agents with completely different membranes. The surface tension of the defoamer must be lower than that of the surfactant, so that the defoamer can be used spontaneously. It was developed on the existing membrane.

Alkylglycosides are alkylglycosides synthesized from glucose and fatty alcohol. They are widely used in real life. There may also be many friends who don't know it very well. Here we will give you a detailed introduction of its performance characteristics.

The environmental problem is a concomitant problem of industrial development. Today, the major textile exporters all over the world have launched "green products" and "environmental protection products", we should pay attention to environmental protection and ecological indicators, and strive to develop green surfactants with good environmental compatibility, excellent ecology and excellent performance.

In order to adapt to the international development trend, the surfactant industry in China started late and the foundation was weak. In order to adapt to the international development trend, it should focus on the development of glycoside surfactants; systematically research and develop soybean phospholipid surfactants, which have both surface activity and biological activity, and are special surfactants; develop sucrose fatty acid ester series products, sucrose fatty acid ester has non-toxic,

In the building materials, most of the building plastics are flammable materials, a few are flammable materials. Plastic has the characteristics of high combustion heat, high gun temperature, fast combustion speed, releasing a lot of smoke and toxic gases in fire. Therefore, building plastics must have flame retardant properties. Professional flame retardant manufacturers will introduce the flame retardant treatment methods of building materials to you.

Alkyl polyglycoside refers to the synthesis of alkyl polyglycoside with glucose and fatty alcohol. It is widely used in real life, and many friends may not know it very well. Let's introduce its performance characteristics.

Surfactant plays an important role in emulsion polymerization of industrial scale polymer production. Emulsion polymerization needs four components: water, monomer, surfactant and initiator. The concentration of surfactant in the system should be higher than the critical micelle concentration to ensure the formation of micelles.

The solubilization of surfactant promotes the supersaturation of oxygen in aqueous solution, which is equivalent to increasing the saturated solubility of oxygen in aqueous solution. The saturation solubility of oxygen in aquaculture water is generally less than 9 mg / L. the addition of surfactant can increase the saturation solubility of oxygen in aquaculture water.

It can produce rich and delicate bubbles. Because of these delicate bubbles, the friction of clothing, especially fine clothing, such as wool and silk products in washing machine, is reduced, which is beneficial to fabric protection.

Some surfactants can be used to disperse fine solid particles (especially pigments) in liquids. Surfactants attach to pigment particles by selective adsorption.
