The foam is not aqueous solution, and the non-aqueous solution often produces a foam. If there is a surfactant, since the surface of the foam can be adsorbed, the surfactant molecule can be adsorbed, and when the molecules of these orientation arrangements with the foam surface reaches a certain concentration, the foam wall forms a sturdy film. Surfactant molecules are adsorbed in the surface of the gas liquor so that the bubble is not easy to merge.DDAC manufacturer  The relative density of the bubble is much smaller than the water, floating on the surface, and when the rising bubble passes through the liquid surface, the upper surface active agent molecule of the liquid surface is adsorbed. Therefore, the air bubble film of the adsorbed surfactant in the air is different from the bubble film in the solution, which comprises two layers of surfactant molecules. Shenzhen real stone paint is a thick slurry sand coating.double decyl dimethyl ammonium chloride supplier  Due to the rough film texture, the influence of the antifoaming agent on the coating state is relatively small. However, in actual production and construction, the antifoaming agent has a great impact on true stone paint. Let's take a look at the main ingredients of washing powder and laundry powder. The main ingredient of the washing powder is anionic surfactant: sodium alkylbenzene sulfonate. The main component of the washing powder is a surfactant (nonion + female / cationic surfactant). The anionic surfactant is an effective active ingredient in the detergent, and a film is formed on the surface of the eyeglass. This hydrophilic and intake molecule can pull the mist into a water film on the surface of the eye. Not a small bead, so you can't see the fog. Liquid oil is typically attached to the surface of the plastic by molecular weight, and solid particles are typically adsorbed by electrostatic adsorption in the plastic surface. Therefore, during cleaning and decontamination, the interaction of plastic surfaces and dirt is the most basic. Since the surfactant contained in the active water is two pro (a ionized, one hydrophilic) structure, it is preferable to adsorb the two-phase interface, the modifier beam (Fig. 9-11), the space formed by the surfactant bundle Obstacles and electrostatic rejection makes the dirt to aggregate and precipitate, but are suspended in an aqueous solution. The surface of the workpiece after cleaning is replaced by active water. After cleaning, a small amount of monolithic surfactants are separated from the water to the surface of the workpiece, dry the dehydration, obtain the cleaning workpiece, complete the cleaning and removal process. Yuhang Cooling Tower sterilized and algae ingredient ingredients and workpieces mainly adopt mechanical adhesion, molecular energy attachment, static adhesion, etc. When the cruising particles attached to the machine are less than 011 μm, it is difficult to remove, which is based on long-term observation of various crisps conclusions. Super cryogenicity, cleaning is more than three times the common surfactant or common composite surfactant; the waxable performance is superior to the international same type; the wax that cannot be cleaned for common surfactants, can be effectively cleaned; for various waxes There is a highlighted cleaning effect, paraffin, liquid wax, beeswax, stearic acid, solid abrasive matrix, synthetic wax, chlorinated wax, fused oil, polyethylene wax, oxidized polyethylene wax, etc. The main contaminants in the washing sewage come from detergents.N,N-Didecyl-N,N-dimethylammonium Chloride factory  The main active ingredient of the detergent is a surfactant and a detergent. In addition, it also contains bleach, fluorescent whitening, corrosion resistance, foam regulators, enzymes, and other auxiliary components. Sodium alkylbenzene sulfonate (ABS) and sodium linear alkylbenzene sulfonate (LAS) are commonly used in the detergent. ABS is not easy to degrade, and the residence time in the environment is longer. The biological degradation rate of LAS is significantly improved, but both have a benzene nucleus and cannot be completely decomposed. ABS and LAS require phosphate as a detergent. The phosphate discharge water is an important reason for nutrient rich. In addition, detergents can be emulsified and dispersed into hydrophobic organic contaminants such as petroleum products into the water body. A large amount of foam and detergent content in detergent sewage reaches a certain concentration, which brings difficulties to sewage treatment. Good cleaning agents not only have good contrastability, but also have a certain protective role against the skin, which requires us to try to select soft, mild surfactants. Washing companies - Characteristics and hazards of Washing Sewage: Waste Wastewater include washing wastewater, cleaning wastewater and dehydrated wastewater. The washing wastewater contains a large number of short fibers and laundry powder foams, the COD value is high, turbid; 2 cleaning waste water, less foam, small suspension, small COD value, transparent; 3 dehydration waste water, slightly better than clean water quality The main contaminants in the washing wastewater come from detergents. The main active ingredient of the detergent is a surfactant and a detergent. In addition, it also contains a bleach, a fluorescent whitening agent, a corrosion resistant, a foam regulator, an enzyme, and the like. Detergent can be emulsified into hydrophobic organic pollutants such as petroleum products into the water. A large amount of foam and detergent content in detergent sewage reaches a certain concentration, which brings difficulties to waste water treatment. Let us start from conclusion: not all amino acid surfactants are gentle. It is judged that the temperature of the amino acid surfactant depends on its pH, the soap group is not one or not! (1) The anionic surfactant is still widely used in the detergent, rather than the amount of ionic surfactant is increased, and the amount of cationic and amphoteric ionic surfactants is less. This depends mainly on the performance and economic cost of the surfactant.
