Silicone defoamer is a commonly used bright potato defoamer, and its defoaming effect mainly includes the following aspects:

Rapid defoaming: Silicone defoamers are typically able to defoam quickly, typically within seconds to minutes. This is because silicone defoamers have active groups in their molecular structure, which are able to adsorb to the foam surface and destabilize the foam.

Long-term defoaming: Silicone defoamers are able to defoam continuously, i.e. effectively eliminate foam for a period of time after treatment. This is because silicone defoamers are able to form a thin film on the surface of the foam, which effectively prevents the formation of foam and maintains the stability of the foam.

Efficient and environmentally friendly: Silicone defoamer has the characteristics of efficient defoaming, non-toxic, tasteless and non-corrosive, and is widely used in water treatment, sewage treatment, industrial cleaning, chemical cleaning, coatings and other fields, and will not cause harm to the environment and human body.

Silicone defoamer is a white, viscous emulsion. It has been used in various industrial sectors since the 60s, but large-scale and comprehensive rapid development began in the 80s. As a silicone eliminator, its application field is also very wide, and it has been paid more and more attention by all walks of life.

Silicone defoamer is an indispensable additive in the production process in the chemical, papermaking, coating, food, textile, pharmaceutical and other industrial sectors, which can not only remove the foam on the liquid surface of the process medium in the production process, so as to improve the separation, gasification and discharge effects of filtration, washing, extraction, distillation, evaporation, dehydration, drying and other processes, and ensure the capacity of various materials and processing containers.

Whenever we stir a liquid or are introduced into a gas, many bubbles will be generated inside the surface area of the liquid, and some of the bubbles produced by the liquid will quickly break and disappear. Some liquids not only do not disappear, but also accumulate more and more, forming foam. Foam is a dispersion system formed by a large number of bubbles dispersed in a liquid, the dispersed phase is a gas, and the continuous phase is a liquid.

Among them, the volume fraction of the foaming liquid is very small, and the foam occupies a large volume. The gases are separated by a continuous liquid film, forming bubbles of varying sizes, which accumulate to form foam.

Silicone defoamer is a commonly used defoamer, and its defoaming mechanism is mainly as follows:

1.Breaking the surface tension: Silicone defoamers can form a thin film on the surface of the liquid, which can break the surface tension of the liquid, so that the bubbles inside the liquid are not easy to accumulate and form foam.

2.Hinder the formation of bubble wrap: Adding a certain amount of silicone defoamer to the liquid can hinder the formation of bubble wrap, so that the gas inside the bubble is not easy to diffuse, thereby reducing or eliminating the generation of foam.

3.Soluble in water and oil: Silicone defoamers can be dissolved in both water and oil, so they can effectively remove foam from the surface and interface of the liquid, making the entire liquid interface smoother.

4.Foam inhibition: Silicone defoamers can effectively inhibit foam generation by forming a thin film on the surface of the liquid that has the effect of inhibiting foam production.

In short, the main defoaming mechanism of silicone defoamer is to destroy the surface tension, hinder the formation of bubble film and inhibit foam, so that the bubbles inside the liquid are not easy to accumulate and form foam. Therefore, in the process of liquid processing and handling, the bucket silicone defoamer is a very effective defoamer.
