Various surfactants mixed with alkaline additives will have a significant impact on the cleaning ability.
When various surfactants are mixed with alkaline additives, their cleaning ability may be enhanced. Alkaline additives can neutralize the acidic components in the stains, making it easier for the stains to be detached from the surface. For example, when removing oil stains, the oil stains usually contain acidic substances such as fatty acids. Alkaline additives can react with them to saponify, converting insoluble oil stains into water-soluble soap substances, and surfactants can further reduce the surface tension of the solution, making these saponification products easier to disperse and wash away.
The cleaning ability changes of different types of various surfactants mixed with alkaline additives are also different. After anionic surfactants, such as sodium dodecylbenzene sulfonate, are mixed with alkaline additives, their anionic groups are more stable under alkaline conditions, and can better play an emulsifying and dispersing role, thereby enhancing the cleaning effect on stains such as oil stains and dust. When nonionic surfactants, such as polyoxyethylene ethers, are mixed with alkaline additives, their hydrophilicity will change, and to a certain extent, they can also improve the solubility of some stubborn stains.
However, not all mixing can improve cleaning ability. If the mixing ratio is not appropriate, the cleaning effect may be reduced. Too much alkaline additives may corrode certain surfaces and damage the items being cleaned; while too low a surfactant content may not fully play its role in reducing surface tension and dispersing stains.
In addition, cleaning ability is also affected by factors such as the concentration, temperature and use environment of the mixed system. Within a certain range, increasing the concentration of the mixed system can enhance the cleaning ability, but too high a concentration may lead to increased costs and increased environmental burden. Temperature also has an important impact on cleaning ability. Properly increasing the temperature can accelerate the chemical reaction rate and increase the activity of the surfactant, thereby improving the cleaning effect, but too high a temperature may reduce the stability of the surfactant and alkaline additive.
Different types of stains also have different requirements for the cleaning ability of the mixed system. For protein stains, alkaline conditions may cause protein denaturation, but suitable surfactants are needed to assist in removing the denatured protein from the surface. For stains on the surface of some special materials, such as some plastics or delicate fabrics, it is necessary to carefully select the types and proportions of surfactants and alkaline additives to avoid damage to the materials.
In short, the change in cleaning ability after various surfactants mixed with alkaline additives is a complex process, which is affected by a variety of factors. In practical applications, it is necessary to reasonably select the types, proportions and use conditions of surfactants and alkaline additives according to the specific cleaning needs and the characteristics of the cleaned objects to achieve the best cleaning effect.
