Specific applications of silicone defoaming agents for pesticides
During the processing and use of pesticide preparations, when pesticide emulsions, suspensions and other liquids containing surfactants are stirred, shaken or impacted, foam can easily occur. These foams contain toxic substances, so adding silicone defoamer can eliminate them. The main applications of bubbles are as follows:
1. Many bubbles will be generated during pesticide processing, packaging, field dilution and use. Foam treatment has become an urgent problem to be solved in the production and use of pesticide preparations. People use silicone defoamer to eliminate foam in the preparation system, which is very good. Solved the problem of defoaming.
2. The diffusion speed is accelerated and the viscosity is reduced. Defoaming agents are added during the production process to control foam. These substances have low surface tension and are easy to spread on the surface of the solution. After entering the bubble liquid film, they replace the surface active molecules on the original liquid film surface, reducing the surface tension at the contact point. lower than elsewhere in the liquid film. Due to the high surface tension of the foam liquid film, the diffusion speed is accelerated by reducing the viscosity, which shortens the life of the foam and eventually ruptures and is eliminated.
The above is the specific application of silicone defoamer in pesticides. By eliminating bubbles, the purpose of ensuring product quality and producing high-performance pesticides is achieved!
