Surfactant has the ability to strongly adsorb on the surface of particles, adding in the processing of pesticide formulations helps to disperse and suspend the particles, and ensure the re-dispersion when adding water to dilute in the spray barrel to prevent the aggregation of particles.

The research on the application of surfactants in the field of disinfection has developed rapidly in recent years, and the types and quantities of related products approved for marketing are constantly increasing.

Surfactant molecules are first adsorbed on the interface between the oil and the solution. Under the action of the lipophilic and hydrophilic groups of the surfactant, coupled with the convection and stirring of the solution, the oil gradually detaches from the metal surface and enters the solution. , in the form of very small balls to form an emulsion.

Biosurfactants are also used in pulp and paper industry, textile industry, ceramic industry and uranium ore processing. Pellerin and others successfully used the heteropolysaccharide produced by Macrocystis pyrifera and brown nitrogen-fixing bacteria (Azotobacter vinelandii) as a dispersant in the ceramic industry.

At present, there are not many types of high-grade fatliquors. Although there are waterproof, antistatic, antifouling, soft and plump fatliquors, there is a lack of good mercerized fatliquors.

Surfactants are a major component of detergent decontamination formulations. Except for special applications, these products are discharged into the environment after use, either directly or after treatment in sewage treatment plants. However, the anionic surfactants that are relatively difficult to biodegrade are the main ones in detergents.

Mechanism and application of surfactants in tertiary oil recovery.

When the polymer burns, carbon formation in the condensed phase can achieve the purpose of flame retardancy. When the thickness of carbon on the surface of the material reaches 1mm, it can withstand a high temperature of 743°C without catching fire. In coatings, pentaerythritol, polyphosphate and melamine can be used as good carbonizing agent, carbonizing catalyst and blowing agent respectively. If the three are added to the coating in a certain proportion, a flame retardant coating with excellent performance can be made.

Subtilis surfactant (Surfactin), also known as subtilis peptide, is a cyclic ester peptide produced by Bacillus subtilis. It consists of a nonapeptide linked to β-hydroxy-ω-methylmyristic acid by a cyclic depsipeptide bond, and is another well-known class of biosurfactants with antimicrobial properties. According to the amino acid sequence, Surfactin is divided into three types

Glyphosate additives have been widely used in my country. With the increasing environmental protection requirements, low toxicity to aquatic organisms, improvement of product efficacy, different application purposes and specific market requirements, the impact on glyphosate products The research and development of dosage forms also put forward new requirements accordingly.

Biological degradation surfactants is a method that is more studied at present, and has been adopted by some sewage treatment plants. This method can be roughly divided into the active sludge method, anaerobic digestion method, and the method of self -purification of the soil. They all use microorganisms to use the characteristics of the surfactant as the only carbon source to complete the surface active agent to complete the surface active agent. degradation.

In the treatment and recycling of ceramic industry wastewater such as mud and glaze wastewater, precipitants or flocculants are often added. Its role is opposite to the dispersant, which can promote the desertation and gathering of the glue system to improve the dehydration and grouting efficiency of the mud.

During in-situ remediation, the applied biosurfactant may also be adsorbed on the soil, which may also affect the physical, chemical and biological properties of the soil.

When using amino terminated polyether, there are many aspects that need attention. We should not be careless. Only better use of the product can make it give play to its unique performance advantages and achieve good results in application. When using it, we must do a good job, pay attention to the problems that may occur, and then solve them in a timely manner.

The construction process of polyether amine is very simple, as long as you master its operation steps, and then further improve it on this basis. The above introduction is expected to be helpful for your future use.

In the treatment and recovery of ceramic industrial wastewater, such as slurry and glaze slurry wastewater, precipitators or flocculants are often added. Contrary to dispersant, it can promote the destabilization and aggregation of colloidal system, so as to improve the dehydration of mud and grouting efficiency.

Before use, carefully check whether the power cord is connected and robust. The wire of the linear driver of the controller and the cigarette lighter cannot be placed on the lifting link and between the upper and lower bed frames. Frequently check to avoid power failure of the wire. In the process of application, people cannot jump on the bed surface.

Alkyl polyglycosides contain two groups with opposite polarity or solubility. The polar part is a hydrophilic group, and the non-polar part is a hydrophobic or lipophilic group. Generally, it can be divided into non-ionic, anionic, cationic and zwitterionic types.

When aluminum hydroxide is blended with rubber, it is difficult to form a good interface between the two, and a large amount of filling will inevitably cause great damage to the physical and mechanical properties of rubber. Li Juan et al. used ATH, chlorinated paraffins and Sb2O3 together. The inorganic flame retardant ATH can meet the higher flame retardant requirements without having to be filled with a very high fraction, and at the same time, it does not affect the physical and mechanical properties of rubber.

Alkyl polyglycoside surfactant, synthesized from renewable natural fatty alcohol and glucose, is a new type of non-ionic surfactant with comprehensive performance. It has the characteristics of both common non-ionic and anionic surfactants, high surface activity, good ecological security and solubility, and is internationally recognized as the first choice of "green" functional surfactant.
