AI Technical Summary
In the production process of water-based metallic coatings, excessive stirring can lead to the introduction of a large amount of air, generating bubbles. Allowing the mixture to stand and defoam requires a significant amount of time, which affects the production speed.
A combination of vacuum defoaming and mechanical defoaming is used. A vacuum pump creates a vacuum state, causing the bubbles to expand and burst. Defoaming mesh and defoaming needles are used to mechanically break the bubbles. Combined with the stirring effect of the stirring component, the defoaming efficiency is improved.
It accelerates the defoaming speed of water-based metal coatings, improves production efficiency, reduces the time for static defoaming, and enhances the practicality of the reactor.
