The working principle of organosilicon defoamer is to achieve defoaming effect by reducing the surface tension of the liquid. A thin film is formed on the liquid surface to prevent the formation and diffusion of bubbles or foam. This thin film can form a physical barrier on the surface of the liquid, preventing bubbles from generating or diffusing in the liquid. The molecular structure of organosilicon defoamers enables them to effectively adsorb on the surface of bubbles, disrupting their stability and causing them to rapidly rupture and dissipate.
In addition, organosilicon defoamers can also be applied in fields such as oilfield exploitation, papermaking, detergents, paints, and coatings. In oilfield exploitation, organosilicon defoamers can prevent bubbles generated in oil wells from hindering the flow and extraction of oil. In the papermaking industry, organosilicon defoamers can prevent bubbles in the pulp from affecting the quality and smoothness of the paper. In detergents, paints and coatings, silicone defoamers can prevent bubbles or foam from forming during construction, and improve the uniformity and quality of coatings.
