Saudi Arabia pesticide industry cooperation case

The Saudi Arabian customer is engaged in the pesticide suspension industry. They have equipped our pesticide sand mill.

The rapid grinding and stability have been recognized by the customer. Suspension is a viscous and flowable suspension formed by mixing the pesticide original drug with a carrier and a dispersant and ultra-finely dispersing and grinding by wet method. It is a solid original drug that is insoluble or slightly soluble in water with the help of certain additives, and is dispersed in water relatively evenly through ultra-fine grinding to form a highly suspended, flowable and stable liquid-solid system with fine particles. Suspension is usually composed of active ingredients, dispersants, thickeners, anti-precipitants, defoamers, antifreeze agents and water.

The manufacturing technology of suspension concentrate is relatively complex. Because its technology involves multiple disciplines such as pesticide chemistry, pesticide formulation, physical chemistry, and chemical machinery. Although suspension concentrates have appeared as early as the 1970s, their promotion scale is relatively limited due to the development of technologies such as grinding machinery and surfactants.

At present, most suspension concentrate products produced in China have poor physical stability, are prone to stratification and precipitation during storage, and the active ingredients of pesticides are difficult to disperse evenly, and even agglomerates cannot be poured out of the packaging, which seriously affects the promotion and use of suspension concentrates, a new pesticide formulation, in agricultural production.

First of all, the pesticide suspension must determine the formula and processing route, that is, determine a processing method based on the properties of the active ingredients of the selected pesticide. In addition, the selection of wet dispersion grinding equipment for processing is also very important, which often affects the quality of the product. Li Tengda's special pesticide suspension processing equipment for sand mills for pesticides has advanced technical levels and provides production value for its industry.
