How to select surfactants for clay stabilization and acidizing measures
1.Surfactants for stable clay Stabilizing clay involves two aspects: preventing the swelling of clay minerals and preventing the migration of clay mineral particles. For preventing clay swelling, cationic surfactants such as amine salt type, quaternary ammonium salt type, pyridinium salt type, an...Read more -
How to select surfactants for the exploitation of heavy oil and waxy crude oil
1.Surfactants for heavy oil extraction Due to the high viscosity and poor fluidity of heavy oil, its exploitation is faced with numerous difficulties. To recover such heavy oil, aqueous solutions of surfactants are sometimes injected into the downhole. This process converts the high-viscosity hea...Read more -
The Relationship between the Structure and Dispersibility of Surfactants
Aqueous dispersion systems are most commonly used, and they can typically be employed to analyze the relationship between surfactant structure and dispersibility. As hydrophobic solid particles, they can adsorb the hydrophobic groups of surfactants. In the case of anionic surfactants, the outward...Read more -
The Five Major Functions of Surfactants
1.Emulsifying Effect The comprehensive affinity of the hydrophilic and lipophilic groups in surfactant molecules for oil or water. Based on experience, the range of the Hydrophilic-Lipophilic Balance (HLB) value of surfactants is limited to 0–40, while that of non-ionic surfactants falls within 0...Read more -
How much do you know about the wetting and solubilization effects of surfactants
Wetting effect, requirement: HLB: 7-9 Wetting is defined as the phenomenon where the gas adsorbed on a solid surface is displaced by a liquid. Substances that can enhance this displacement capacity are called wetting agents. Wetting is generally categorized into three types: contact wettin...Read more -
The development of green surfactant technology and products
Green surfactant technology and products have advanced rapidly, with some achieving internationally leading standards. The production of novel green surfactants using renewable resources such as oils and starches has become a major focus in recent research, development, and industrialization effo...Read more -
Application of Surfactants in Asphalt Pavement Construction
Surfactants have extensive applications in asphalt pavement construction, mainly including the following aspects: 1. As Warm Mix Additives (1) Mechanism of Action Warm mix additives are a type of surfactant (e.g., APTL-type warm mix additives) composed of lipophilic and hydrophilic groups ...Read more -
What are the principles behind the emulsifying and solubilizing actions of surfactants?
The steadily growing global trend of surfactants provides a favorable external environment for the development and expansion of the cosmetics industry, which in turn imposes increasingly higher demands on product structure, variety, performance, and technology. Therefore, it is imperative to syst...Read more -
What do you know about crude oil demulsifiers
The mechanism of crude oil demulsifiers is rooted in the phase-transfer–reverse-deformation principle. Upon addition of a demulsifier, a phase transition occurs: surfactants capable of generating an emulsion type opposite to that formed by the emulsifier (known as reverse-phase demulsifiers) come...Read more -
What are the factors that contribute to emulsion stability
Factors Governing the Stability of Emulsions In practical applications, the stability of an emulsion refers to the dispersed phase droplets’ ability to resist coalescence. Among the metrics for gauging emulsion stability, the rate of coalescence among dispersed droplets is paramount; it can be d...Read more -
What are the applications of nonionic surfactants
Nonionic surfactants are a class of surfactants that do not ionize in aqueous solutions, as their molecular structures lack charged groups. Compared to anionic surfactants, nonionic surfactants exhibit superior emulsifying, wetting, and cleaning capabilities, along with excellent hard water toler...Read more -
What are fatty amines, and what are their applications
Fatty amines refer to a broad category of organic amine compounds with carbon chain lengths ranging from C8 to C22. Like general amines, they are classified into four major types: primary amines, secondary amines, tertiary amines, and polyamines. The distinction among primary, secondary, and tert...Read more
