Alkyl glucosides have the advantages of ordinary nonionic and anionic surfactants: high surface activity, high viscosity, rich foam, fine and stable. It has obvious synergistic effect with other surfactants; It has strong dispersibility to calcium soap and can be used in hard water; Very low irritation to epidermis, mucosa and living cells; It is easy to biodegrade in the natural environment and has less environmental pollution. APG is formed by condensation of starch or its hydrolyzed sugar with fatty alcohol. The source of raw materials is very wide, which has attracted more and more attention in recent years.

Anionic surfactants such as alkyl naphthalene sulfonate, lignin sulfonate, alkyl thiosuccinate, polyoxyvinyl alkyl aryl sulfonate, etc; Nonionic surfactants such as polyoxyvinyl alkyl ether, polyoxyvinyl alkyl phenyl ether, polyoxyvinyl styryl phenyl ether, polyoxyvinyl alkyl ester, low substituted hydroxypropyl cellulose, hydroxymethyl starch sodium, microcrystalline cellulose, cross-linked polyvinylpyrrolidone, cross-linked carboxymethyl fiber sodium, effervescent disintegrating agent, etc, Two or more surfactants can be used.

Pesticide is usually prepared into liquid by its pesticide preparation, and then sprayed on crops. The pesticide preparation is made by adding various surfactants on the basis of the original pesticide. In practical application, not only a single adjuvant is used. In order to improve the efficacy, a variety of adjuvants can be used at the same time, but the interaction between all kinds of adjuvants must be paid attention to, so as to prevent the unnecessary photodegradation of pesticides and reduce the efficacy.

Flame retardant is the application of flame retardant technology in real life. It is a special chemical additive used to improve the combustion performance of combustible materials, and is widely used in flame retardant processing of various decoration materials. The material processed by flame retardant can effectively prevent, delay or terminate the spread of flame when attacked by external fire source, so as to achieve the effect of flame retardant.

The dilute solution of surfactant obeys the law of ideal solution. The adsorption capacity of surfactant on the surface of solution increases with the increase of solution concentration. When the concentration reaches or exceeds a certain value, the adsorption capacity does not increase. These excessive surfactant molecules are disordered or exist in a regular way in the solution. Both practice and theory show that they form a complex in solution, which is called micelle.

It is increasingly recognized that the use of flame-retardant materials is one of the strategic measures to prevent and reduce fire. It is a special chemical additive used to improve the combustion performance of flammable materials, which is widely used in the flame-retardant processing of various decoration materials. The material processed by flame retardant can effectively prevent, delay or terminate the spread of flame when attacked by external fire source, so as to achieve the effect of flame retardant.

Biosurfactants meet the requirements of functional food and green food additives, and can be used in functional food. Today and even in the future, biosurfactants will become a widely used food additive.

The common surfactants are coupling agents, higher fatty acids and their salts, unsaturated organic acids and organosilicon. Coupling agent is a common mineral surfactant.

Organic fluorine surfactant is one of the most active surfactants so far. On the one hand, it can reduce the surface tension to a very low value, on the other hand, it has a small amount of surfactant. Its unique properties are summarized as "three high" and "two abomination", namely, high surface activity, high chemical stability and high heat resistance stability; Its fluoroalkyls are hydrophobic to both water and oil. Another excellent performance of organic fluorine surfactant is that it has good mixing performance with hydrocarbon surfactant, and the mixture has higher ability to reduce surface tension. As long as a few organofluorine surfactants are added to the preparation, the performance of the preparation can be improved obviously.

In addition to changing the activity of aqueous solution, that is, reducing its surface tension, various washing related properties, such as penetration, adsorption, wetting, dispersion, emulsification, colloidal solution, foaming, etc., will change significantly near the critical micelle concentration.

Polyether amine, as a curing agent with elastic function, can make epoxy cured products have abundant tensile elongation and tensile strength. If the planning and manufacturing are proper, polyether amine technology can fully meet the functional requirements of low viscosity, good penetration function, strong adhesion, high tensile elongation and tensile strength.

In the series of alkyl glycosides, alkyl glycosides as a non-ionic surfactant are particularly effective in removing oily dirt. Alkyl polyglycosides have the following advantages when used in laundry detergent

When using polyether amine, it is inevitable that there will be improper operation, which is caused by our lack of understanding of it. The direct way to solve this problem is to master its basic contents, so it will be easier in case of emergency. Next, let's briefly introduce its emergency treatment, I hope you will know how to deal with these situations in the future.

Because of the hydrophobicity of organic pollutants and the possibility of pollutants being strongly adsorbed on the surface of soil particles or entering the soil pores, the concentration of pollutants in water solution will be reduced, which will result in the isolation of microorganisms and pollutants. Because microorganisms can not use extremely low concentration of pollutants, the degradation of pollutants will stop or slow down. Therefore, the decisive factor of degradation of organic pollutants in bioremediation is the low water solubility of pollutants, which limits the bioavailability of pollutants.

Polyether amine is a kind of chemical product with various applications. However, when it is applied, we usually use it as curing agent. As a curing agent with superior performance, what are the specific characteristics of polyether amine when it is used? Let's get to know it through the following. I hope you can use it better next time.

In the formula of degreasing agent, defoaming mainly starts from two aspects: adding defoaming agent or adjusting formula. The commonly used defoamers are liquids which are easy to spread on the surface of bubbles. When the defoamer spreads on the liquid surface of the bubble film, it will take away the liquid from the adjacent surface layer and make the liquid film thin locally, so the liquid film breaks to achieve the purpose of defoaming.

In the process of synthesis and production of APG surfactant, dealcoholization is a key step in industrial production. Due to the high boiling point of higher alcohols used in APG synthesis, it is very difficult to remove them.

Polymer flame retardant is a hot spot and heavy research area in recent years. This kind of flame retardant has the characteristics of easy dispersion, good compatibility and little influence on mechanical properties of materials, and has a good application prospect. This paper is inspired by this, the traditional melamine flame retardant modified by polymer, to produce polymerized melamine flame retardant, which has the advantages of traditional flame retardant and polymer flame retardant, can effectively improve the flame retardant performance and mechanical properties of the material.

Surfactant will produce a lot of acid mist in acid pickling, which not only affects the health of workers, but also pollutes the environment. At the same time, it will corrode the plant and equipment. In order to improve the rust removal effect of acid pickling and prevent acid over corrosion, adding surfactant into sulfuric acid or nitric acid in acid pickling can inhibit acid mist, speed up acid pickling and prevent over corrosion. Formula: hydrochloric acid 1 ~ 10% nitric acid 1 ~ 8% kingly phenolic acid polyoxyethylene 0.1 ~ 20%.
