Two states that affect the defoaming of defoamers
Defoamers have strict requirements for strong alkali and strong acid environments, which are mainly manifested in static and dynamic situations:
Defoaming in static conditions; when the liquid that produces bubbles flows back into a relatively fixed container, the defoaming effect is obvious at this time. When the gas enters the bubble, the external air pressure decreases, which is conducive to the generation and stability of bubbles. The defoamer has a shrinking effect on the bubble, which can accelerate the defoaming and cover a wide range.
Defoaming in dynamic conditions; using a stirring stick machine to rotate at high speed in a narrow space, bubbles are generated quite quickly, and dynamic temperature changes will also cause changes in defoaming.
Whether it is static or dynamic defoaming, it is necessary to do it in an appropriate amount to effectively control and eliminate bubbles. If it is used before the foaming liquid is foamed, the effect is best.
