Hypertonic auxiliaries are commonly used in nonionic, anionic, and anionic and nonionic hybrid types, all of which are in the category of surfactants. Regardless of the use of any type of hypertonic agent, its common application characteristics are: good wettability, spreadability, adhesion and strong penetrating ability, in the correct application, can achieve knockdown Fast speed, anti-raining, significantly improve the efficacy, reduce the amount of pesticides , reduce the cost of preparation, reduce environmental pollution and reduce the resistance of agrochemical products to harmful organisms, and improve the systemic effect of drugs on plants. A common feature of hypertonic agents is that they have different degrees of surface tension reduction (the surface tension of standard water is 72mN/m). Generally speaking, the surface tension of hypertonic agents is mostly below 40mN/m. The surface tension of the agent is as low as 20.5 mN / m. The lower the surface tension value, the faster the product's expansion speed, but the quality of the high-permeability agent cannot be defined by the expansion speed of the auxiliary agent. The expansion speed does not represent the speed of the penetration force of the additive, and the quality of the high-permeability agent. And the reasonable selection depends on the speed values ​​of the "wetting speed" and the "penetration force" of the hypertonic agent species. Therefore, the faster the wetting rate and the penetration force of the hypertonic agent, the more the effect of the hypertonic agent Ok, the quality will be better. Although the quality of some hypertonic agents is excellent, but the price is expensive, the addition amount is large and too high to increase the cost of the preparation, or because the pH value is easily decomposed and unstable under the acid-base condition, and the user is also far away. Therefore, the basis for selecting high-purity and high-permeability agents is to scientifically determine the time values ​​of "wetting rate" and "penetration" of different concentrations of hypertonic agents and their corresponding ladder experiments and stability experiments. value. Only in this way can the true quality of the hypertonic agent be identified and the variety of the corresponding hypertonic agent selected.
