  • 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.

    2021-04-21 16:51:38
    In order to adapt to the international development trend, the surfactant industry in China started late and the foundation was weak. In order to adapt to the international development trend, it should focus on the development of glycoside surfactants; systematically research and develop soybean phospholipid surfactants, which have both surface activity and biological activity, and are special surfactants; develop sucrose fatty acid ester series products, sucrose fatty acid ester has non-toxic,
  • The quality of flame retardant can not be judged by single method

    2021-04-19 13:31:37
    In the building materials, most of the building plastics are flammable materials, a few are flammable materials. Plastic has the characteristics of high combustion heat, high gun temperature, fast combustion speed, releasing a lot of smoke and toxic gases in fire. Therefore, building plastics must have flame retardant properties. Professional flame retardant manufacturers will introduce the flame retardant treatment methods of building materials to you.

  • Surfactant can prevent or solve many problems in coating technology

    2021-03-31 15:56:59
    The paint may produce high surface tension during spraying and maintain the high surface tension until sprayed onto the bottom, so the initial wetting effect is not good. Surfactants can be used to change this state, but it is necessary to choose them because the amplitude and speed of surfactant reducing dynamic surface tension are different. The effect of water soluble surfactants on reducing dynamic surface tension is very small, but not easy to dissolve in water.
