Generally, surfactant and oil are always used together. Surfactant can effectively reduce the static friction coefficient of fiber material, while oil can reduce the dynamic friction coefficient of fiber material.
  • After adding alkyl glycoside surfactant into aquaculture water

    2020-03-24 16:25:53
    Oxygenation principle of surfactant: the saturated solubility of oxygen in aquaculture water can be increased by adding alkyl glycoside surfactant. According to hydrate formation theory and bimembrane theory, due to the low solubility of oxygen in water, water oxygenates in water generally form at the gas-liquid interface first, and then slowly diffuse from the gas phase to the liquid phase. Due to the solubilization of surfactants, a large amount of oxygen is dissolved in the surfactant micelles formed in the aqueous solution, so that the formation of water oxygenate in the surfactant aqueous solution can not only occur at the gas-liquid interface, but also in the water body, reducing the formation time of water oxygenate, and improving the oxygen in the water body Solubility in.

  • What are the capabilities of anionic surfactants in practical applications?

    2020-03-20 16:21:56
    In addition to being used as antistatic agent and smoothing agent, anionic surfactant can also be used as wetting agent. Succinate sulfonate is a good wetting agent. Adding this kind of surfactant into the oil agent can improve the affinity of the oil agent to the fiber, so that the oil can be evenly applied, and the oil application rate (o.p.u) can be increased as required. A series of products can also be produced with different carbon chains of R group and different EO number. However, the commercial penetrant ot (aerosol OT) is commonly used. The surface activity of OT is still strong, and its interface ability to mineral oil can reach 5.86 (mnm-1) at 0.1% concentration. However, it should be noted that when the product is mixed with other ionic and non-ionic surfactants, it is easy to make the mixture unstable, so in practical application, it should not be added as much as possible on the basis of achieving the osmotic wetting ability. Or it can be used together with other non-ionic surfactants with strong wetting ability to meet the requirements of oil agent function.
  • What are the effects of amphoteric surfactants in oil?

    2020-03-18 10:26:18
