Advantages and Uses of Nonionic Surfactants Nonionic surfactants are surfactants whose molecules contain ether groups that do not dissociate in aqueous solution as the main hydrophilic group, and their surface activity is reflected by neutral m...
Three Types of Polyurethane Catalyst Product Introduction Polyurethane products can be roughly divided into foams, elastomers, and polyurethane resins. Below, WHAMINE will analyze the selection of polyurethane catalysts for these three types of products.1. F...
Introduction to the Structure and Cloud Point of Surfactants Surfactant refers to a substance that can significantly change the interface state of the solution system by adding a small amount. Surfactants are generally organic amphiphilic molecules with hydroph...
What is the Difference Between Primary, Secondary and Tertiary Amines? Ⅰ. How many amines are primary amines?Primary amines are primary amines, and amines are hydrocarbon derivatives. According to the number of hydrocarbon groups connected to the nitrogen atom in the am...
Requirements and Types of Surfactants for Oil Production 1. Requirements for surfactants in oil displacement(1) The surface activity on the oil-water interface is high, which reduces the oil-water interfacial tension to below (0.01-0.001) × 10-5N/cm, and h...
Physical and Chemical Properties of Aromatic Amines Aromatic amines refer to amines with an aromatic substituent, i.e. -NH2, -NH or nitrogen-containing group attached to an aromatic hydrocarbon. The structure of aromatic hydrocarbons usually contains o...
Application of Amphoteric Surfactant Products Amphoteric surfactants are surfactants that contain both anionic and cationic hydrophilic groups in the same molecule, whose biggest feature is that it can both give and accept protons. In the process...
What Are Cationic Surfactants? Cationic surfactants are mainly nitrogen-containing organic amine derivatives. Because the nitrogen atom in the molecule contains a lone pair of electrons, it can combine with the hydrogen in the acid...
What Are the Characteristics of Cationic Surfactants? Surfactant refers to a substance that has fixed hydrophilic and lipophilic groups, can be aligned on the surface of the solution, and can significantly reduce the surface tension. Hydrophilic groups a...
Fatty Amine: an Important Product of Oleochemical Industry Aliphatic amines refer to a large class of organic amine compounds with a carbon chain length in the range of C8-C22. Like general amines, they are divided into four categories: primary amines, second...
Application of Non-ionic Surfactants 1. Application of non-ionic surfactants in leather processingIn a series of leather processing techniques, although the amount of leather auxiliaries used is small compared to the weight of the leathe...
Introduction to the Main Performance of Polyurethane Catalyst For relatively simple polyurethane coatings, polyurethane catalysts still have certain limitations in their shape, gloss, water resistance and hardness during industrial production and application. Th...
Application of Fatty Amine Polyglyceryl Ether Surfactant Fatty amine polyglyceryl ether surfactant also has the structure of organic amine, which makes it have some characteristics of nonionic and cationic surfactants at the same time: when the addition num...
Polyurethane catalyst is an important chemical reaction promoter Catalysts are an important additive in the synthesis of resins, and this is no exception for polyurethane. Polyurethane catalysts shorten reaction time, improve production efficiency, selectively prom...
Cationic surfactant industry development status and trend Cationic surfactants are mainly nitrogen-containing organic amine derivatives. The nitrogen atoms in their molecules have lone pair electrons, which can form hydrogen bonds with hydrogen atoms in acid...
