What is silicone defoamer

Dear user friends, do you often see a lot of bubbles in daily life and industrial production? The appearance of these bubbles will not only slow down the progress of industrial production, but also affect the use of equipment, and even affect the quality of the product. certain influence. Therefore, silicone defoamer came into being.

Silicone defoamer is a kind of defoamer made from silicone oil and silicone. It is a white viscous emulsion. It is a silicon-containing surfactant, a family of organosilicon compounds, which has been used in various industrial fields since the 1960s, but its large-scale and comprehensive rapid development began in the 1980s. As a silicone defoaming agent, its application fields are also very wide, and it has attracted more and more attention from all walks of life. Silicone defoamers are usually of the polysiloxane type. For example: polydimethylsiloxane containing acrylate functional groups and polyether-modified polydimethylsiloxane. Therefore, organic silicones have high temperature resistance, low temperature resistance, stable physical properties, chemical inertness, and very low surface tension, and are commonly used defoaming agents.

Silicone defoamer has a wide range of applications and is suitable for various industries such as water treatment defoaming, coatings, adhesives, industrial cleaning, metal washing, agricultural fertilizers, fermented foam, oil field mining and other industries.

So why do we use silicone defoamer? What are its advantages and features?

1. After the silicone defoamer is added, it can quickly dissolve into the foam, reduce the surface tension of the foam, destroy the elasticity of the liquid film, and achieve the purpose of rapid defoaming and long-term foam suppression;

2. It has good water solubility and fast dispersion, and can quickly dissolve with the original solution without oil drift or precipitation;

3. Adding it to the original solution will not affect its performance and quality, nor will it change its appearance and color.
