Capsule Suspension refers to a pesticide formulation in which a small container with a core-shell structure is formed by synthetic or natural polymer materials, the pesticide is coated in it, and suspended in water. It includes two parts: a capsule shell and a capsule core. The capsule core is a pesticide active ingredient and a solvent, and the capsule shell is a film-forming polymer material. This dosage form is divided into a continuous phase and a discontinuous phase. The continuous phase is water and additives, and the discontinuous phase is the coated pesticide microcapsules.

1.The lasting effect is long, the pesticide ingredients are released slowly after application, and the underground application can last for 80-120 days.
2.The contact toxicity and peculiar smell are greatly reduced, and the harm to the operators is greatly reduced;
3.Reduce phytotoxicity, and prevent the harm of chemicals to seeds and seedlings when used for seed dressing or root irrigation.
4.The active ingredients are isolated from water and alkaline pesticides, and when used with alkaline pesticides, their stability will not be affected.
5.The amount of organic solvents is reduced by 30-100%, which greatly reduces the environmental pollution caused by harmful aromatic hydrocarbons, which is beneficial to environmental protection.
6.The use of medicine during the flowering period of fruit trees reduces the harm to bees and other beneficial organisms and protects natural enemies.
7.Reduce the number of medications and the amount of medications used, which is conducive to saving labor and resources.
8.Pre-emergence herbicides can reduce leaching, so that the active ingredients are adsorbed on the soil surface (the adsorption is mutual), which is conducive to the formation of a chemical soil film, thereby improving the utilization of pesticides and reducing phytotoxicity, and avoiding negative crop yields.

Shanghai Rucca also optimizes the production equipment of suspension concentrate to meet the bead mills needs of more customers.
Production process of suspension concentrate
1. Feeding: small batch, manual operation, large batch, automatic operation.
2.High-shear dispersion: uniform mixing, initially dispersed to below 70 microns;
3.First-level coarse grinding: use grinding media 1.6-1.8, and the fineness reaches about 10 microns;
4.Two-stage rough grinding: use grinding media 1.0-1.2, and the fineness reaches about 5 microns;
5. Fine grinding: use medium 0.7-0.8, fineness reaches about 3 microns;
6.Finally to save.

The main purpose of such grinding is to grind the technical material to the required particle size. Generally, D90 requires 5 microns, strictly <3 microns. For now, traditional sand mills have the following problems: adopt dynamic and static ring separation, can not use small grinding media; low grinding efficiency; large product particle size, wide distribution, affecting efficacy and storage; more bubbles, affecting efficiency; production There is a phenomenon of stuck beads; the mechanical seal is easy to leak and pollutants flow, which affects production.

However, Shanghai Rucca group uses a sand mill with a static centrifugal structure, which can effectively increase the flow area and increase the output; use fine zirconium beads to improve product quality.
Compared with the traditional sand mill, its advantages are
1.The discharge area is large, and a small medium can be used to maintain a large flow;
2.Can use tiny grinding media,and reduce the cost of medium.
3. High energy density design, high efficiency, narrow particle size distribution, and large output;
4.Not easy to break beads, easy to maintain, and higher equipment stability;
5.Strong scalability to meet the different needs of customers.

And the advantages of the machine itself can only be known by yourself, so Shanghai Rucca also has a special laboratory for customers to test in order to obtain more accurate data.
