Attenuation mechanism of foam
Under the condition of gravity and pressure difference, the liquid membrane of foam will flow and discharge liquid unevenly, and the gas in the bubble will continue to diffuse and permeate due to the different pressure difference on both sides of the bubble membrane, so the instability of foam itself is mainly reflected from the dynamics. [4]
The attenuation mechanism mainly includes the diffusion of gas through the liquid film and the discharge of liquid from the liquid film. These two properties are inherent attributes of foam itself, and have nothing to do with the existence of surfactant. However, these two attenuation mechanisms only play an obvious role in the initial stage of foam system formation. With the attenuation of foam system, these two effects gradually weaken, making the foam attenuation rate gradually slow. [
Sweden The antifoaming agent for aquaculture wastewater treatment is paint defoamerfor the aquaculture wastewater industry system. It can quickly disperse in water, is easily soluble in water, is not easy to break emulsion and float oil, and is fast in paint defoamer and long in inhibiting foam. It does not change the oxygen content of water quality or the microorganisms in the water, and has good acid and alkaline resistance, wide application range, and good chemical stability.
