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...
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...
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...
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...
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...
