How to Use Polyurethane Catalysts to Reduce Bubbles in Products? 1. Three main sources of bubbles in polyurethane catalysts(1) Introduce air into raw material stirring(2) Solvent volatilization during curing(3) Side reactionsGenerally, it is possible to change the ...
Functions of Dodecyl Dimethyl Amine Oxide Dodecyl dimethyl amine oxide (lauryl dimethyl amine oxide) is a colorless or slightly yellow transparent liquid at room temperature. It is a special type of surfactant, which is colorless or slightly ...
Definitions and Types of Amines 1. Definition of amineThe definition of amine in organic chemistry is "a derivative of ammonia." It comprises nitrogen atoms with lone pairs of electrons and is classed as an organic nitroge...
Chemical Properties of Primary Amines 1. Stability of primary aminePrimary amine is flammable, and its vapour may combine with air to generate explosive combinations, with an explosion limit of 5% to 21%. (4.95 percent -20.75 percent ). A...
Roles and Principles of the Surfactant 1. Emulsification of the surfactantDue to the large surface tension of oil in water, when oil is dropped into the water and stirred vigorously, the oil is crushed into fine beads and mixed with each o...
Preparation Method and Application of Primary Amine Amines are organic compounds in which the hydrogen atoms of ammonia are replaced by hydrocarbon groups. The compounds formed by replacing one, two or three hydrogen atoms in the ammonia molecule with ...
Application of Surfactant in Pesticide Emulsion The pesticide produced in the factory is called technical medicine before it is processed into shape. The solid technical substance is called raw powder, and the liquid technical substance is called c...
Application of Surfactant in Basic Formulation of Pesticide 1. The application of surfactants in wettable powdersWettable powders are powdery formulations that can be wetted by water when added to water. Surfactant wettable powder is composed of pesticide orig...
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...
