Zwitterionic Surfactants
An amphoteric surfactant refers to a surfactant having both an anionic and a cationic hydrophilic group, and thus the surfactant is cationic in an acidic solution, anionic in an alkaline solution, and...
Functions of Cationic Surfactant – Wetting Effect
Wetting effectWhen the solid is in contact with the liquid, the original solid/gas, liquid/gas interface disappears and a new solid/liquid interface is formed. This process is called wetting. For exam...
Functions of Cationic Surfactant – Emulsification
Emulsification refers to two liquids (such as oil and water) that are not in phase with each other. One of the liquids is uniformly dispersed into another liquid with very small particles (particle si...
Functions of Cationic Surfactant – Suspension Dispersion
The process by which insoluble solids are dispersed into a solution to form a suspension with very small particles is called dispersion. The surfactant which acts to promote solid dispersion and form ...
Functions of Cationic Surfactant – Foaming Effect
The state in which the gas is dispersed in the liquid is called a bubble. If a liquid is easily formed into a film and is not easily broken, the liquid will produce a lot of foam when it is stirred. T...
Functions of Cationic Surfactant – Solubilization
Solubilization refers to the effect of the surfactant on increasing the solubility of poorly soluble or insoluble materials in water. For example, the solubility of benzene in water is 0.09% (volume f...
Functions of Cationic Surfactant – Antistatic Effect
Soft and smoothWhen the surfactant molecules are aligned on the surface of the fabric, the relative coefficient of static friction of the fabric can be reduced. Non-ionic surfactants such as linear al...
Information About the Uses of Surfactants
1. Concept of surfactantsSurfactant refers to a substance that can significantly change the interface state of the solution system by adding a small amount. It has fixed hydrophilic and lipophilic gro...
What Are the Functional Groups of Amines?
1. Definition of amine functional groupCarbonyl groups are also present in carboxylic acids, esters and amides. However, in these compounds, the carbonyl group is only part of the functional group. Ca...
Types of Surfactants
1. Anionic SurfactantSuch active agents are more common in linear alkyl benzene sulfonate and sodium α-alkenyl sulfonate. Linear alkyl benzene sulfonate, also known as LAS or ABS, is a white or light...
What Are the Types of Polyurethane Catalysts?
The commonly used catalysts in the synthesis of polyurethane and its raw materials mainly include amine catalysts and organometallic compounds. There are many varieties of amines and organometallic co...
Reasons for Deactivation of Polyurethane Catalysts
1. Preparation and synthesis methods of polyurethane catalystsIn a three-necked flask with a reflux condenser and a stirrer, mix up 227.2g polyethylene glycol with an average hydroxyl number of 187mgK...
Characteristics and Classifications of a Surfactant
