Main manifestations that affect the defoaming ability of defoaming agents
The main functions of defoamers are to suppress foam, defoam and break foam, and they are widely used in various industries. So what are the main manifestations that affect their defoaming ability?
First, the defoaming ability of defoamers in static conditions. When the liquid that produces bubbles flows back into the storage tank or directly into the packaging barrel, the environment is relatively sealed, the defoamer is increased in volume by the surfactant, and then the addition of colloidal resin can be absorbed, which is one of the factors affecting its defoaming ability.
Second, the defoaming ability of defoamers in dynamic conditions. The flowing environment is prone to produce gas, because it involves gas entering the bubbles, and the external air pressure is reduced in a short time, which is more conducive to the generation and stability of bubbles. Wetting agents and emulsifiers are added, and the two substances are used to shrink and stabilize the gas in the bubbles, and defoaming is also used.
Therefore, whether it is a dynamic environment or a sealed and narrow environment, the basic conditions for defoaming must be met, and the addition of appropriate agents can ultimately achieve the purpose of making the defoaming time longer and the defoaming effect better!
