Characteristics and storage of agricultural defoamer
Jul 08, 2024
Agriculture is an important foundation for the construction and development of a country's national economy, I am the world's largest agricultural importer and exporter, the development of agriculture is also rapidly changing. In the process of rapid development of agriculture, it is also inseparable from the use of pesticides, such as herbicides used in weeding, insecticides used to kill insects and so on belong to pesticides. Agricultural defoamer is a kind of anti-foaming agent applied in the process of pesticide production, which is of great help to the improvement of pesticide production efficiency and the optimisation of production quality.
In the production process of pesticides, many chemical additives will be added, the surface activity of chemical additives is very strong, after mixing and vibration, it becomes a foaming substance, which produces a lot of foam. In addition, during the production, the chemical additives in the pesticide react with each other to produce carbon dioxide gas, which also leads to the non-stop production of bubbles; when shaking and vibrating, many bubbles will also be produced.
The accumulation of a large number of bubbles will cause the solution to overflow to the periphery, and the overflowing solution not only causes a waste of raw materials, but also pollutes the surrounding environment. In addition, the foam penetrates into the machine, will cause machine failure, resulting in machine stoppage and production, slowing down the pesticide production schedule. Agricultural antifoam agent is based on silicone as raw materials through a special process of compounding. It has the following characteristics:
1. Good dispersion performance, easy to disperse in water, solution, will not be deposited at the bottom of the solution;
2. Good defoaming and foam inhibition performance, defoaming thoroughly without residue, after adding, in the packaging, transport and use of the process will not appear the phenomenon of secondary foaming;
3. It will not affect the basic properties of the original solution, and will not affect the use of other chemical additives;
4. It is recommended to add 0.1%-0.5%, a small amount can achieve the desired antifoaming effect;
5. It can still maintain good defoaming property under high temperature, strong acid and alkali;
6. Will not pollute the environment, environmentally friendly products.
Storage of agricultural defoamer:
Agricultural defoamer is generally stored in a cool, dry and ventilated place at room temperature, avoiding direct sunlight. The diluted defoamer can not be stored for a long time, it should be used in a short time to complete.
