1. Biochemical oxidation surfactants widely used in the washing are meaningless to the biological purification of urban sewage. However, since its allowed concentration in water is very low, especially the nonionic surfactant contains phosphorus compounds in urban sewage, these pollutants in urban sewage must be further processed, thereby causing the cost of contaminated water treatment. Precision of Washing Sewage can enter the surfactant and polymeric phosphorus compound in the urban purification structure. Dispersing agents include surfactants. Small molecule inactive electrolyte. Polymer dispersing agent and coupling agent. The polymer dispersing agent is most important, and the polyelectrolyte is most important. Amino acid wash water refers to shampoo that is a primary surfactant as an amino acid surfactant. Amino acids are the basic unit of protein. Amino acid surfactants are amino acids of coconut oil, laurel oil or palm oil, with foaming and removal ability. Therefore, it is possible to repair the hair using amino acid washing. The name of several amino acid surfactants is simply listed. When you purchase an amino acid washing, you can compare the formula. You may ask, what is a surfactant? Here is a word - shampoo. We often say shampoo is a liquid made from surfactants. emulsification. Solid products can help clean the dirt of the head. The shampoo can be cleaned, mainly relying on surfactant. Surfactant is a substance containing hydrophilic group and a lipophilic group. During the shampoo, the ionure tail is combined with sebum or other oil, and the hydrophilic head is left in the water. Under a micelle formed by multi-surfactant molecules, the dirt is forced to pull and suspend in the water to clean clean. In addition, a small amount of acyl amino acid is added to some have a few have a relatively low rankings in the ingredient table. They are not the main surfactant ingredients, but they dominate. They are called amino acid detergents. Even some products are only equipped with a small amount of amino acids. The body of the formulation structure is a soap group, and they are also considered to have an amino acid washing face. The active agent removal oil mainly relies on the emulsification and mechanical force of the surfactant, but should pay attention to the reduction of detergent foams during use; the mechanical physiothenesis method is simple, the method is more, such as wiping, flame combustion method, thrown blasphemore. In fact, each removing method has its own advantages, so in the specific floor, it can be used according to the specific oil contrast, and the specific removal plan can be developed. The stability of the foam is closely related to surface viscosity. The surface viscosity has a large solution of the bubble life, which is difficult to remove. Further, the foam is also related to the type of surfactant, the properties and concentration of the additive. 3. Surfactant: Mainly a fatty acid group or an aromatic nonionic surfactant. Its main function is to reduce the surface tension of solder and pin metal, enhance the surface wetting force, enhance the permeability of the organic acid activator, foaming agent. Amino acid surfactants have been widely used in cosmetics and hygiene products in recent years, but we also want to remind you that amino acid is clean now, we should open your eyes when you choose. It is clear that the ingredient table is an amino acid surfactant, rather than a simple amino acid component. The basic composition of the amino acid surfactant is: oil + anl + XX amine + XX salt. Second, the components of the general cosmetic are based on the component content from large to small arrangement, the more components. Real amino acid cleaning products, the amino acid table must be the best in the ingredient table. Only two of the above two conditions can be satisfied, it can be considered true amino acid cleaning. Silica gel defoamers mainly have two types of emulsions or mixture defoamers and oil or dispersible defoamers, suitable for different occasions. Emulsion or mixture defoamer is a hydrophobic silicone oil defoaming agent that does not contain polar functional groups, mainly consisting of polydimethylsiloxane containing silica particles, which can effectively control the foam caused by the surfactant. Applicable to high viscosity system; oil or dispersion antifoaming agent is a hydrophobic silicone oil defoaming agent containing a polar functional group, mainly used to eliminate high viscosity foams in aqueous coating, more than mineral oil system defoamers Good stability. The market share of this defoaming agent is increasing, and the ink system is used for polyether modified antifoaming agents.
