Petroleum composition is often very complex, and this complexity is often interwoven with the complexity of structural components of contaminated soil, resulting in the complexity of pollution characteristics and consequences.

In the past two years, the Ministry of science and technology of the people's Republic of China, two major oil companies, PetroChina and Sinopec have organized a series of research projects on surfactant compounding, and organized large oil fields, scientific research institutes and universities to carry out a series of research projects, and achieved some basic research results. In the surfactant flooding system of Zhongyuan Oilfield, Changqing Oilfield, Dagang Oilfield and Yanchang oilfield, several low permeability reservoirs have been selected for field test, and the effect of EOR is obvious. In Zhongyuan Oilfield, the displacement efficiency of composite surfactant in formation water is 7.68% higher than that of petroleum sulfonate. Shengli Oilfield developed a low-cost composite surfactant for oil displacement in Zhuangxi area with high temperature and low permeability. The exploratory application test of the agent was carried out in No.5 zhuangzang 50 well group in 2006. As of May 2007, the oil production of 6 wells in this well group increased by 1656 tons.   

Surfactants can also be used as dispersant, wetting agent, foaming agent, crystallization control agent, bactericide and so on in food production, and also can prolong the fresh-keeping period of food.

Surfactants are one of the main components of detergent detergents. Except for special purposes, these products are discharged into the environment directly or after being treated by sewage treatment plants. However, anionic surfactants, which are difficult to biodegrade, play an important role in detergents. The discharge of surfactant containing wastewater not only directly harms the aquatic environment, kills microorganisms in the environment, inhibits the degradation of other toxic substances, but also leads to the reduction of dissolved oxygen in water, especially the nitrogen and phosphorus containing surfactants will cause eutrophication of water. When the concentration of surfactant in wastewater reaches a certain concentration, it will affect many processes such as aeration, sedimentation, sludge nitrification, etc.

A new type of polyol type non sucrose fatty acid esters (SE) is a new type of polyol non-ionic surfactant, which is white or yellowish brown powder, block or yellowish viscous resin. Since the hydrophilic lipophilic equilibrium (HLB) of sucrose fatty acids does not change with temperature, the range of HLB is wide (1-16). Sucrose ester can be used not only as w / O emulsifier, but also as O / W emulsifier. Sucrose ester has good emulsifying, dispersing, solubilizing, penetrating, foaming, viscosity adjusting, anti-aging, antibacterial and other properties. At the same time, it is non-toxic, especially safe to human body, non irritating, degradable, and will not cause environmental pollution. Due to its excellent characteristics, sucrose ester is widely used in food, chemical industry, cosmetics, etc Oil mining, fruit preservation, textile and agriculture industries. Se is a food additive and medicinal material recommended by FAO and who. China also approved the use in the 1980s.

The use of surfactants alone has little harm. There are two reasons for the damage to crops caused by surfactants in pesticides. One is that surfactants increase the solubility of drugs, and the other is the effect of surfactants on crops. For example, after spraying wheat chemical hybrid agent genesis, there is burning phenomenon on the last two leaves of plants.

Surfactant in pesticide is one of the indispensable components of pesticide preparation which can not be used directly. It can not only improve the use effect of pesticides, but also reduce the amount of pesticides, reduce the impact of pesticides on the environment, and bring great benefits to agricultural production.

Polyether amine in the production or transportation storage, for each step of the operation requirements must be accurate, not sloppy, then the above on the chemical safety technology knowledge, I hope to help you.

The application of surfactants in leather production has broad prospects, but there is still a certain distance from surfactants to leather additives. How to use surfactants skillfully in leather production requires the combination of surfactant researchers and Leather Technologists, starting from the characteristics and needs of leather processing, to do in-depth and detailed research. However, with the progress of society, environmental protection is more and more advocated and valued by people, and the development of leather industry is bound to be challenged. Therefore, it is very urgent to develop and research new surfactants for leather production.

The fabric itself is easy to ignite and burn, so in order to increase the safety, it is necessary to add flame retardant into the fabric after processing. In this way, once the fire occurs, the fire will not be intensified immediately, and it can be effectively isolated.

At present, flame retardants are mainly divided into organic, inorganic, halogen-free and halogen-free. Among the organic flame retardants, brominated flame retardants have some advantages in many aspects, but they have been hotly discussed by environmental protection experts. In halogen-free flame retardant system, red phosphorus can be regarded as an excellent role, with the advantages of less addition, good flame retardant effect, wide application range and good environmental protection effect.

Sealant is one of the commonly used materials in buildings, which can be used for sealing and bonding various joints or holes in building parts such as building exterior enclosure, interior decoration and window structure. Different building joints have different requirements for the performance of sealant. The sealant used in exterior wall, bathroom, toilet, kitchen, balcony, floor heating system floor, insulating glass and other building parts should have high waterproof and moisture resistance.

Surfactant industrial cleaning agent manufacturers found that the current industrial cleaning agent industry is almost the same as the "traditional manufacturers", and they basically follow the old road of traditional industrial cleaning agent manufacturers, and the marketing means are also poor. Industrial detergent manufacturers believe that for industrial detergent manufacturers, it is a good choice to boost social marketing with the help of distributors.

Biosurfactant is a kind of multifunctional and excellent treatment agent, which has the characteristics of biodegradation and low toxicity. It has a wide application prospect in environmental remediation. But up to now, due to the high production cost, it is still unable to compete with the synthetic chemical products on the market, which also affects its wide application. It is necessary to improve the production process of microbial surfactant, increase the yield and reduce the production cost. A kind of

Polyether amine in the use, it is inevitable that there will be improper operation, this is due to our lack of understanding of it, then the direct way to solve this problem is to integrate its basic content, so that it will be easier in case of emergency. Next, we will briefly introduce its emergency handling matters I hope you will know how to deal with these situations in the future.

The halogen-free flame retardant for PP is a kind of nitrogen phosphorus flame retardant. It is a halogen-free and intumescent flame retardant specially developed for polypropylene. It has good compatibility in polypropylene, has little effect on the mechanical properties of plastics, and has excellent processing stability in the processing process. PP special environmental flame retardant is different from halogen-containing flame retardant. In the process of combustion, dense expanded carbon layer is produced to achieve the purpose of heat insulation and air flame retardant, without irritating hydrogen halide gas and black smoke. It is an environmental friendly flame retardant.

Polyether amine technology is mainly through a series of technology to produce the products we need, so what are the characteristics of the products produced? I hope you can deepen the understanding of polyether amine in the following introduction.

In the application of surfactants in cosmetics, anionic surfactants are more and more widely used. They have rich foaming property, good emulsifying ability, moderate cleaning power and special skin affinity, which can meet the requirements of hair cleansers. Cationic surfactants can be used in hair care products, Including hair conditioner and hair styling gel, it is also a very effective antistatic agent to make hair more supple. Zwitterionic surfactant itself has low toxicity, low irritation to skin and eyes, so it is widely used.

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 by 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 aspects, people have a strong interest in the use of this technology in the industrial field. The enhancement of global environmental awareness has promoted the trend of biosurfactants replacing chemical surfactants.

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.
