The defoamer has the characteristics of small dosage and obvious effect. It is widely used in industrial production. The performance characteristics and application environment of different types of defoamers have certain pertinence, and the dosages are also different. The defoamer is affected by the penetration coefficient and the dispersion coefficient.
For the defoamer to be effective, these two coefficients need to be greater than zero
Defoamers are generally added in small amounts and are called "industrial monosodium glutamate". The defoamer needs to have good defoaming and anti-foaming effects. If the system has foamed, you can walk quickly to destroy the elastic membrane of the bubble and make it burst. When the system is going to foam, the defoamer can prevent the production of bubbles.
In order for a defoaming agent to have defoaming and anti-foaming effects, it must have the following performance characteristics: low surface tension, low HLB value, insoluble in the foaming medium, but can be evenly dispersed in the foaming medium, resulting in continuous, Balanced defoaming ability.
For the defoamer to work, it must first penetrate into the liquid film between the foams. The penetration capacity of the defoamer is represented by E (E>0), that is, the penetration coefficient of the defoamer needs to be positive; secondly, the penetration of the defoamer On the liquid film, it must be quickly dispersed. The dispersion capacity can be represented by the dispersion S (S>0). That is to say, the dispersion coefficient of the defoamer also needs to be positive. When the penetration coefficient and the dispersion coefficient of the defoamer are both For this reason, defoamers have defoaming capabilities.

The defoamer must be targeted for purchase-the effect is more ideal
The defoamer needs to have good penetration and dispersion properties in order to eliminate and inhibit foam well. The defoaming agent has a certain pertinence. When in use, it can be purchased according to its own environment and the requirements of the defoaming agent. A single defoaming agent can be added, or multiple defoaming agents can be used together to enhance the defoaming effect. At present, compound defoamer is a trend, mainly for the general effect of compound defoamer, and it is easy to use.
