    2021-06-15 11:15:43
    From the perspective of actual use effect, the fuel additive containing polyether amine (PEA) does have a good carbon removal effect, but it is just a gimmick for the promotion of fuel saving and power improvement. These effects can hardly be detected in the actual use process, unless your engine has too serious carbon deposition, it just helps you recover to the normal level.

    2021-05-26 16:27:08
    Alkyl polyglycosides are white powder, the actual product is cream or light yellow, it has no obvious melting point. It is soluble in water 'ethylene glycol' pyridine, but insoluble in general organic solvents. The solubility in water decreases with the increase of alkyl chain length and increases with the increase of degree of polymerization.
  • Application principle of surfactant in water based metal cleaning agent

    2021-05-24 09:01:33
    The application principle of surfactant in water-based metal cleaning agent is to weaken or offset the adhesion of oil on metal surface by the properties of wetting, permeation, emulsification, dispersion and solubilization of surfactant. The oil is emulsified into the washing solution by mechanical and physical methods, and then it is suspended or solubilized in micelles.
  • Emulsification and foaming of alkylglycosides

    2021-05-21 16:01:59
    Alkyl glucosides have the advantages of ordinary nonionic and anionic surfactants: high surface activity, high viscosity, rich foam, fine and stable. The results showed that the combination with other surfactants had obvious synergistic effect; It has strong dispersing ability to calcium soap, and can be used in hard water; The stimulation to epidermis, mucosa and living cells is very low; It is easy to be biodegraded in natural environment and less pollution. APG is made from starch or hydrolyzed sugar and fatty alcohol. Its raw material is very wide, and more and more attention has been paid to APG in recent years.
  • At night, surfactant has obvious effect on increasing dissolved oxygen in water

    2021-05-19 16:07:25
    The solubilization of surfactant makes oxygen molecules supersaturated in water solution, which is equivalent to increasing the saturation solubility of oxygen in water. The saturated solubility of oxygen in aquaculture water is not more than 9mg / L. when surfactant is added to the aquaculture water, the saturation solubility of oxygen in the aquaculture water can be increased.
  • The importance of alkyl polyglycosides in cosmetics industry

    2021-05-17 16:58:12
    Alkyl polyglycosides in the cosmetics industry, solvent mainly used in cosmetics, hair oil, hair and other products. Due to the differences in structure and polarity of oily components in cosmetics, the mechanism of solubilization is also different.
  • The dilute solution of surfactant obeys the law of ideal solution

    2021-05-14 16:23:50
    The dilute solution of surfactant obeys the law of ideal solution. The adsorption capacity of surfactants on the surface of the solution increases with the increase of the concentration of the solution. When the concentration reaches or exceeds a certain value, the adsorption amount will no longer increase. These excess surfactants molecules are disordered or exist in a regular way. Both practice and theory show that they form a connective complex in a solution, which is called micelles.

  • The combination of surfactants has synergistic effect

    2021-05-06 10:10:44
    Surfactant can reduce the interfacial tension and make the wetting angle θ Near zero, the solid powder can be dispersed spontaneously in surfactant solution. Meanwhile, surfactant can help liquid wet the inner surface of solid, make liquid penetrate into the channel and void between the particles' internal aggregates, provide certain pressure, and under the action of mechanical force, the reinforcement bond force of particle aggregation will be destroyed. At the same time, surfactant can help grind, reduce the surface energy of particles, prevent the surface of damaged surface from bonding, and thus achieve the purpose of preventing particle aggregation.

  • The surface tension of defoamer must be lower than that of surfactant

    2021-04-27 14:44:23
    Compared with ionic surfactants, nonionic surfactants have less foam generation and are less stable. Some surfactants are easily soluble in water and can't reduce the surface tension below 30dyne / cm. For example, alkyne glycol system, organic silicon system (Tegopren) and fluorine (perfluorooctanoate) surfactant are very water-soluble and can reduce surface tension to below 25dyne/cm. They are all effective defoamers. The mechanism of defoaming is to replace the foaming surface film produced by easily foaming surface active agents with completely different membranes. The surface tension of the defoamer must be lower than that of the surfactant, so that the defoamer can be used spontaneously. It was developed on the existing membrane.
