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.

With the increasingly prominent environmental problems of chemical surfactants, the application of biosurfactants has attracted more and more attention. In the late 1980s, the development of biosurfactants using bioengineering technology has become a new topic in the field of international bioengineering. In the past 20 years, with the rapid development of modern biotechnology and the application of biosurfactants in oil exploitation, environmental protection, pharmaceutical, food processing and other fields, people have a strong interest in using this technology in the industrial field. The enhancement of global environmental awareness has further promoted the trend of biosurfactants replacing chemical surfactants.

In acid bath dyeing, amino groups of silk can absorb acid, neutral, direct dyes and anionic surfactants with negative charges. At this time, anionic surfactants and dyes compete for dye bases according to their affinity. When anionic surfactants have a larger affinity, the rate of dye adsorbed by fibers slows down, which reduces the dye uptake rate of anionic dyes.

The removal of silicone structural adhesive should be different from that of edible and non edible utensils. A good way is to remove it by physical methods. Use steel wire balls, knives and water sandpaper. For thick and much local areas, use a knife to scrape, then use steel wire balls to scrape, and finally use sandpaper to polish. Pay attention to avoid that the utensils that are crossed should be careful to prevent the glass glue from falling off, The removal of all-purpose glue stains, clothes infected with all-purpose glue stains, can use acetone or banana water drop on the glue stains, to use a brush to repeatedly wash, after the glue stains become soft and take off from the fabric, then rinse with water. If it can't be done at one time, it can be rinsed several times and finally cleaned. Do not use this method for fabrics containing acetate to prevent damage to the fabric.

Polyether amine can be used as curing agent, mainly to play a good viscosity, so in the field of application is relatively broad, it generally contains the primary amine connected to one end of the main chain of polyether. The main chain generally has the mixed structure of EO, PO or EO / PO, so it is named "polyether amine". One of the purposes is to use it as curing agent of epoxy jewelry adhesive. Why choose it as curing agent?

Alkyl polyglucoside (APG) is a new kind of green, mild and non-toxic non-ionic surfactant which has been developed in the world since 1990s. APG has excellent properties, low surface tension, strong detergency, rich foam, fine and stable, no irritation to human skin, complete biodegradation, no pollution to the environment, and many characteristics of non-ionic and anionic surfactants. It is compounded with most surfactants, which can enhance the efficiency of other surfactants, especially in the aspect of ecological safety. Therefore, it is called "green surfactant".
