IntroductionAlthough industrial cleaning has existed for only a few decades, it has brought tremendous economic and social benefits to manufacturing industries.With the rapid advancement of cleaning technologies, industrial cleaning now spans virtually every industrial sector, including textiles and

IntroductionSurfactants are essential components in cosmetics, widely used for cleansing, emulsifying, dispersing, wetting, and foam formation.Depending on the type of hydrophilic group, surfactants can be categorized into anionic, cationic, amphoteric, and nonionic surfactants.Today, let’s review s

1. Surface Tension The contraction force per unit length acting on the surface of a liquid is called surface tension, expressed in units of N·m⁻¹. 2. Surface Activity and Surfactants The ability of a substance to reduce the surface tension of a solvent is referred to as surface activity, and substa

Have you ever wondered how industrial companies keep their equipment and machinery clean and free from grease and grime? The answer lies in industrial degreasers. These specialized cleaners are designed to effectively remove even the toughest grease and dirt, helping equipment maintain optimal perfo

Aqueous metal cleaning is primarily achieved through the functions of surfactants, such as emulsification, wetting, solubilization, penetration, dispersion, corrosion inhibition, and chelation.Surfactants can modify (usually reduce) the interfacial tension between two phases. They are amphiphilic co

Nonionic surfactants refer to surfactants that do not ionize in aqueous solution. Their hydrophilic groups are mainly composed of oxygen-containing groups (typically ether and hydroxyl groups). The lipophilic part of the molecule is derived from higher fatty alcohols, alkylphenols, fatty acids, fatt

Polyaspartic polyurea resins represent a class of reactive oligomers derived from the Michael addition of dialkyl aspartates with secondary amines. Distinguished by their low viscosity, adjustable reactivity, and high functionality, these resins have become essential building blocks in modern polyur
