In addition to changing the activity of the solution in the water solution, the surface active agent in the aqueous solution, that is, reduce its surface tension, and various properties related to washing, such as penetration, adsorption, moisturizing, dispersing, emulsification, gum, foaming, etc., in critical glue A significant changes will occur near the bundle concentration.

The surfactant used in the synthetic detergent is not a very pure single compound, and often contains more or less adjacent homes. Moreover, the surfactant does not account for 1/3 of the total weight in the detergent formula. The rest are various additives and auxiliary agents, which plays a different role. Therefore, the role of multiple composite detergents in the process of washing is a complex comprehensive process.

Surface active agent: After adding the surfactant to the breeding water body, the saturated solubility of oxygen in the breeding water can increase. According to the theory and bilateral theory of hydrophilic objects, because the solubility of oxygen in water is small, the water -oxygen compounds in the water body generally first form in the qi -liquid interface, and then slowly spread from the gas phase to the liquid phase.

In the water body containing surfactants, due to the soluble effect of the surfactant, the surfactant beam formed in the water solution is dissolved in a large amount of oxygen, so that the formation of the water -oxygen compound in the water solution in the surface activated agent can not only be the formation of water -oxygen compounds, At the same time, the liquid -liquid interface can also occur inside the water body, reducing the formation time of water -oxygen compounds, and increasing the solubility of oxygen in the water body.

Traditional oxygen is often an oxidation compound such as sodium carbonate, calcium peroxide, and excessive carbide. There are disadvantages of low oxygen volume and short action time. Research on aquatic drug developers shows that some surfactants have a good oxygen effect. For example, the use of twins coconut oil beet -alkali can inhibit the excessive reproduction of anaerobic microorganisms in the water body and quickly reduce the interface tension of water and air. Let the oxygen in the air import a large amount of oxygen into the water body, so that the level of soluble oxygen from the low -soluble oxygen level of the LMg / liter is 4-5.5 mg / liter.
