Alkyl polyglucoside surfactants can form hydrophobic groups on the surface of the fiber and reverse adsorption outwards, so as to reduce the dynamic and static friction coefficient of the fiber material, so as to obtain a smooth and soft handle. Generally, surfactants and finishes are always used together. Surfactants can effectively reduce the static friction coefficient of fiber materials, while finishes can reduce the dynamic friction coefficient of fiber materials. The effect of soft lubrication can be expressed by the difference between static friction coefficient and dynamic friction coefficient. The smaller the difference is, the stronger the soft lubrication is.

Surfactant molecules have both hydrophilic and lipophilic groups, which is also called amphiphilic. Due to this characteristic of surfactants, they can form micelles in water at appropriate concentration: the hydrophilic head is attracted by water outward, and the lipophilic tail is repelled by water and faces inward. In the process of washing clothes, oil stains are pulled to the interior of micelles by lipophilic groups, and the whole micelles are taken away by water.

Surfactants, also known as interfacial active agents, are organic compounds that greatly reduce the interfacial tension of solutions at low concentrations. The molecules contain hydrophilic polar groups (such as hydroxyl, carboxyl, sulfate, amino and ether bonds) and hydrophobic nonpolar groups (such as various C-H chains). According to their structures, they can be divided into four types: anionic, cationic, nonionic and amphoteric.

Polyether amine technology is often used as a kind of foaming agent after polyether amine is generated. Of course, it is because of the existence of such products that we can achieve a good effect when using products. However, when we use it in styrofoam, what should we pay attention to?

In the washing process of textile processing, some processes should not only consider the washing effect, but also consider the softness and fading of the fabric. Therefore, the development of new surfactants with good washing effect and maintaining the softness and color stability of the fabric has become a hot spot in the research and development of new surfactants.

Surfactant is known as "industrial monosodium glutamate". It is not only widely used in chemical industry and many other traditional industries and technology fields, but also in high-tech fields such as materials, energy and life science.

The production of biosurfactant by fermentation has the advantages of low production cost, variety and simple technology, which is convenient for large-scale industrial production, but the cost of separation and purification of the product is high.

Sealant is a kind of material widely used in our life. It is a kind of similar ointment, which is a kind of adhesive commonly used in family. Its main components are sodium silicate (Na2O · msio2), acetic acid and organic silicone. Once the material is exposed to the air, it will solidify and play a role of adhesion, and the adhesion performance of different types of silicone adhesive is not the same. Deacetylation, dealcoholization and deamination are the main components of silicone adhesive. Because the cured silicone adhesive is translucent, it is also called glass adhesive.

The price of sealant is not the higher the better, there are many kinds of sealant, silicone sealant, polyurethane sealant, polysulfide sealant and so on. And each kind of sealant classification is different, it has different classification standards, can be classified according to the base material, can also be classified according to the purpose, can also be classified according to the performance.

New gemini surfactants and biosurfactants are widely concerned because of their high efficiency and environmental friendliness. The solubilization efficiency of Gemini surfactants and biosurfactants is higher than that of traditional surfactants.

What are the requirements for the application of flame retardants in foam plastics? With the expansion of the application scope of rigid polyurethane foam, the performance of foam plastics has higher requirements, among which flame retardants are the main problem. Rigid polyurethane foam is widely used in refrigerators, refrigerators, refrigerators, refrigerators and other insulation materials. The basic defects of buildings, tanks and pipes are flammable. Now, together with the flame retardant manufacturers, what is the requirement for the application of flame retardants in foam plastics?

In the process of continuous improvement and improvement of polyether amine technology, it has been more and more perfect, and the products produced have also been greatly improved. It is mainly used as a curing agent. Then through the improvement of technology, the application field of polyether amine curing agent is also expanding, and it will develop to other different industries in the future.

The surface viscosity is closely related to the firmness of the surface film. Because the membrane has surface pressure and viscosity, it must be elastic. The higher the surface pressure and viscosity, the greater the elastic modulus. The elastic modulus of the surface adsorption film is very important in the process of foam stabilization.

The trend of surfactant's steady growth in the world provides a good external environment for the development and expansion of cosmetics industry, and the requirements for product structure, variety, performance and technology are also higher and higher. Therefore, it is necessary to systematically develop safe, mild, biodegradable and special surfactants, provide theoretical basis for the development and application of new products, focus on the development of glycoside

In recent years, although the small functional varieties of surfactants have developed rapidly, there is still a big gap between the total number of varieties and the demand of developed countries and industries. It is still necessary for the whole industry to make joint efforts, innovate and tackle key problems, develop new varieties, and then fill the gap, catch up with the development, and adapt to the demand.

Surfactants are special structural molecules with hydrophilic and lipophilic groups, so they have a series of application functions, and are widely used in various fields of plastic industry as auxiliaries.

Flame retardant is a kind of functional assistant which can give flame retardancy to flammable polymer. It is mainly designed for flame retardancy of polymer materials. There are many types of flame retardants, which can be divided into additive flame retardant and reactive flame retardant according to the use method. At present, the additive flame retardants mainly include organic flame retardants and inorganic flame retardants, halogen flame retardants (organic chloride and organic bromide) and non halogen flame retardants.

The conversion method is also called two-step method. Firstly, low-carbon glucoside is formed by the reaction of glucose and low-carbon alcohol, and then high-carbon glucoside is formed by the alcohol exchange reaction of low-carbon glucoside and high-carbon alcohol. This method solves the problem of the solubility of glucose and high-carbon alcohol between raw materials, makes the synthesis easier to realize, and overcomes the disadvantage of producing caramel in the process of direct glycoside, but the process is complex, and the transformation of low-carbon glycoside and high-carbon glycoside is not complete generally.

Silicon containing surfactant is a new type of surfactant developed with the development of new silicone materials. It not only has the characteristics of high temperature resistance, weather aging resistance, non-toxic, non corrosive and high physiological inertia, but also has excellent performance of reducing surface tension. It is a special surfactant next to fluorine-containing surfactant. In the textile industry, silicon-containing surfactants give textiles soft, smooth feel, anti-bacterial, anti-static, hydrophilic, waterproof and other special functions.
