What factors affect the defoaming effect of defoamer? - Jiangsu Saiouxinyue Defoamer Co., Ltd.

The following factors will affect the defoaming effect of the Defoamer:

Types and ingredients of defoamer: Different types of defoamer have different defoamer principles and scope of application. For example, Silicone defoamer works well in water-based systems, while polyether defoamer works well in some oil-based systems.

Taking silicone defoamer as an example, if the content of silicone oil is insufficient, it may not be able to effectively play The role of defoamer.

The properties of the foam system: including the pH value of the system, temperature, viscosity, surface tension, etc. For example, at high temperatures, some defoamants may lose their activity; Under acidic or alkaline conditions, the performance of the defoamer may also be affected.

For example, in the treatment of highly alkaline papermaking wastewater, some defoamer may not be effective because it is not adapted to the pH value.

The amount of defoamer: too little may not achieve the ideal defoamer effect, and too much may lead to side effects, such as affecting product quality or other adverse phenomena.

If the amount of defoamer is insufficient in the production of coatings, bubbles may still appear in the coating.

Adding method and timing: adding directly, adding in batches or adding at a specific stage will affect the defoaming effect.

For example, in the fermentation process, if the timing of the defoamer is not appropriate, it may interfere with the normal growth and metabolism of microorganisms.

Stirring speed and intensity: excessive stirring may re-create foam and weaken the effect of the defoamer; Insufficient stirring may lead to uneven distribution of defoamer.

In chemical production, strong agitation sometimes leads to the formation of a large number of foams, at which time the amount of defoamer and the frequency of addition need to be adjusted accordingly.

Compatibility with other additives: If the defoamer interacts with other additives in the system, its defoamer performance may be affected.

For example, in detergent formulations, some surfactants may antagonize the defoamer.

Speed and stability of foam production: If the foam production rate is very fast and high stability, defoaming will be more difficult and may require more efficient defoaming agents or increased dosage.

Like some high-speed stirring reaction systems, foam generation is rapid and stubborn, and the requirements for defoamer are high.

Changes in the concentration and composition of the system: For example, in wastewater treatment, the effect of the defoamer may fluctuate as the composition and concentration of the wastewater changes.

In short, in order to obtain a good defoaming effect, it is necessary to consider the above factors comprehensively, and optimize the selection and use conditions of defoaming agents through experiments and practical applications.
