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%.

From the perspective of actual use effect, the fuel additive containing polyether amine (PEA) does have a good carbon removal effect, but it is just a gimmick for the promotion of fuel saving and power improvement. These effects can hardly be detected in the actual use process, unless your engine has too serious carbon deposition, it just helps you recover to the normal level.

Surfactant is often used in the industrial industry, for the use of surfactant, most of them are used in the washing and textile industry, for all the fine industry, can not leave the use of surfactant. All our industries, including the pharmaceutical industry, are also inseparable from the use of surfactants. In addition, the paper industry is also a field of fine industry. In the paper industry, surfactants are also widely used.

The oil-related structure of surfactants is different from that of long chain hydrocarbons, and the following structures are expanded:

When polyether amine is in production or transportation and storage, the operation requirements of each step should be accurate, and do not be careless. Then, the above knowledge on chemical safety technology is expected to help you.

In recent years, the development and use of environmentally friendly surfactants has been paid more and more attention by the world for the needs of environmental protection and biological safety.

When using polyether amine, we need to pay special attention to ensure the quality of the product, ensure its purity, and not be mixed by other substances. Therefore, when we use this kind of curing agent, we must pay attention to the following matters, so that we can better ensure the use effect of the product.

Amino acid surfactants show good biodegradability, biocompatibility and high safety. They can be decomposed into fatty acids and amino acids by enzymes in human body. The results showed that sodium N-acyl amino acid had less irritation and higher safety than sodium dodecyl sulfate.

There are many kinds of flame retardants. According to the classification of chemical elements, they can be divided into halogen-free flame retardants and halogen-free flame retardants. Halogenated flame retardants include brominated or chlorinated flame retardants, in which organic brominated flame retardants are the main ones; Halogen free flame retardants include phosphorus, phosphorus nitrogen, inorganic metal hydroxide, boron, silicon and molybdenum.

Alkyl polyglycosides are white powder, the actual product is cream or light yellow, it has no obvious melting point. It is soluble in water 'ethylene glycol' pyridine, but insoluble in general organic solvents. The solubility in water decreases with the increase of alkyl chain length and increases with the increase of degree of polymerization.

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.
