Q: How does defoamer work?
A: The working principle of a defoamer is to penetrate the foam board. The anti-foaming agent is insoluble in the foaming medium and has surface activity; it has low viscosity and can spread rapidly on the foam surface. The anti-foaming agent has an affinity with the gas-liquid surface, which makes the foam board destabilize, causing the bubble to burst and the surface foam to burst.
