The washing effect
Sodium alkylbenzenesulfonate is a yellow oily substance, which can form hexagonal or rhombic intense flake crystals after purification. Can be applied in the fruit and clean tableware, alkyl benzene sulfonic acid sodium in the amount of detergent used in the largest, with large-scale automatic production, low price, used in detergent sodium alkyl benzene sulfonate has branched chain structure (ABS) and linear structure (LAS), two kinds of branched chain structure biodegradability is small, can cause pollution to the environment, and linear structure easy biodegradation, biodegradability is greater than 90%, the environmental pollution is small.
Sodium dodecyl benzenesulfonate is neutral, sensitive to water hardness, not easy to oxidize, strong foaming power, high cleaning power, easy to be mixed with a variety of additives, low cost, mature synthesis process, wide range of applications, is a very excellent anionic surfactant. Dodecyl benzenesulfonate has significant decontamination effect on particle dirt, protein dirt and oily dirt, especially on the particle dirt of natural fiber. The decontamination force is enhanced with the increase of washing temperature, and the effect on protein dirt is higher than that of non-ionic surfactant, and the foam is abundant. However, sodium dodecyl benzenesulfonate has two disadvantages. One is that it has poor resistance to hard water, and its decontamination performance can be reduced with the hardness of water. Therefore, the detergent with its main active agent must be used with a proper number of chelating agents. Second, strong degreasing ability, hand washing when the skin has a certain irritation, wash clothes feel worse after the use of cationic surfactant as a softener rinse. In recent years, sodium dodecyl benzenesulfonate is often used in combination with non-ionic surfactants such as fatty alcohol polyoxyethylene ether (AEO) for better comprehensive washing effect. The main use of sodium dodecyl benzenesulfonate is to prepare various kinds of liquid, powder and granular detergents, scrubbers and cleaners.
An emulsifier is a substance that improves the surface tension between the phases in the emulsion to form a uniform and stable dispersive system or emulsion. Emulsifiers are surface active substances with both hydrophilic and hydrophilic groups in the molecules. They concentrate on the oil/water interface, which can reduce interfacial tension and reduce the energy required to form emulsion, thus increasing the energy of emulsion. As an anionic surfactant, sodium dodecyl benzenesulfonate has good surface activity and is hydrophilic. Therefore, sodium dodecyl benzenesulfonate has been widely used in the preparation of emulsions such as cosmetics, food, printing and dyeing AIDS and pesticides.
Any object has its own static charge, which can be either negative or positive. The accumulation of static charge makes life or industrial production affected or even harmful, and the chemical that causes inconvenience or harm to production or life is called antistatic agent. Sodium dodecyl benzenesulfonate is an anionic surfactant, which can make the surface of fabric, plastics and other surface affinity moisture. Meanwhile, the ionic surfactant also conducts electricity, which can make the static electricity leak in time, thus reducing the danger and inconvenience caused by static electricity.
The products of sodium dodecyl benzenesulfonate are widely used. In addition to the applications mentioned above, they are often used as textile auxiliaries for cotton fabric refining, desizing auxiliaries, levelling agent for dyeing, and metal degreasing agent in metal plating process. Used in the paper industry as resin dispersant, felt detergent, deinking agent; Used as penetration degreaser in leather industry; Used as anti-caking agent in fertilizer industry; In the cement industry, it is used in many aspects such as aeration agent alone or as a compound.
