Wetting Agent Make Solid Materials Susceptible to Water Immersion Surfactant Reduce Surface Tension Interfacial Tension

A substance that can make solid materials more easily wetted by water. By reducing its surface tension or interfacial tension, water can unfold on the surface of a solid material or penetrate its surface, thereby wetting the solid material.

 Asubstance that can make solid materials more easily wetted by water. By reducing its surface tension or interfacial tension, water can unfold on the surface of a solid material or penetrate its surface, thereby wetting the solid material. When pesticides are hydrophobic solid powders, their surfaces are not easily wetted by water and are difficult to dissolve in water, causing them to sink and clump. If a wetting agent is added, due to the directional arrangement of wetting molecules on the surface of solids, the surface energy of water is reduced, allowing water to wet these solids and disperse the solid powder in water into a stable suspension. For example, there is wax on the surfaces of plant leaves and insects, and when the medicinal liquid is sprayed, it becomes a spherical shape due to its inability to moisten or forms after water evaporates. In order to achieve good wetting properties of the medicinal liquid and spread it on the surface of plant leaves and insects, in order to fully exert its effectiveness, it is often necessary to add wetting agents to pesticides. The wetting effect is more practical in chemical experiments, and after completing the experiment, the glass instrument must be washed clean. The cleaned glass instrument wall should be covered with a thin and uniform water film instead of water droplets. If there are water droplets hanging on the glassware, it indicates that the oil is not clean and must be washed again.
