In industrial production and daily application, the generation of foam often has a negative impact on production efficiency, product quality and even safety. Therefore, the importance of defoaming performance as a key indicator for measuring the effectiveness of defoamers is self-evident.
Defoaming performance refers to the ability of defoamer to quickly eliminate foam in liquid system and inhibit the generation of new foam. It is mainly composed of three dimensions: defoaming speed, defoaming efficiency and foam suppression durability: defoaming speed refers to the time required for defoamer to be added to the foam system until the foam is significantly reduced. Defoaming efficiency is a measure of the thoroughness of defoamer to eliminate foam, usually expressed as the percentage of foam volume reduction. Foam suppression durability is to evaluate the ability of defoamer to prevent the formation of new foam within a period of time.
The optimization of defoaming performance is a key link in improving industrial production efficiency and product quality. The optimization of defoaming performance is based on the principles of surface chemistry, especially the mechanism of action of surfactants. The molecular structure of surfactant directly affects its adsorption capacity and stability on the surface of foam. The concentration of defoamers, whether too high or too low, may affect the defoaming effect, and the optimal addition amount needs to be found. Changes in system conditions such as temperature, pH value, and ionic strength can also affect defoaming performance.
The optimization of defoaming performance is a continuous process that requires constant exploration and innovation. With the advancement of technology and the strengthening of environmental awareness, defoamers will develop towards higher efficiency, environmental friendliness, and intelligence in the future. Meanwhile, interdisciplinary collaboration and cross industry communication will also provide more possibilities and opportunities for optimizing defoaming performance.
