In many industrial production and processing processes, the appearance of foam is often a headache. Whether in the chemical, food, pharmaceutical, or coating, sewage treatment and other industries, foam may bring a series of problems, such as reducing production efficiency, affecting product quality and even increasing production costs. The correct use of defoamers is particularly important. So, how to master the use of defoamers to achieve the best results?

1. Choose the right defoamer

Choosing the right defoamer is the first step to success. Different processes and environments require different types of defoamers. For example, high-temperature resistant defoamers should be selected for high-temperature environments, while under acid and alkali conditions, corresponding acid-resistant or alkali-resistant defoamers need to be chosen. In this process, it is crucial to understand the performance and scope of the application of defoamers.

In addition, in some fine chemicals or food processing, if the foam may affect the production process or product quality, adding a defoamer before foaming is an effective preventive measure. For example, in pharmaceutical or cosmetic production, adding a defoamer in advance can prevent the generation of foam, control the foam from the source, and ensure smooth production.

2. Adding method: more is not better

Accurately controlling the amount of defoamer added is the key to ensuring the effect. The more defoamer might not be the better. Excessive addition will not only increase costs, but may also cause side effects. Therefore, conducting a small-scale test before actual use to determine the most appropriate amount.

In terms of adding method, if the system is relatively simple and easy to stir, you can choose to add the defoamer directly; for more complex systems, you can dilute the defoamer before adding it to ensure that it is evenly distributed in the system.

3. Continuous observation and dynamic adjustment

During use, it is very important to continuously observe the defoaming effect. If you find that the defoamer is not effective, do not rush to increase the dosage, but analyze the possible reasons first. For example, changes in system temperature or adjustments in stirring speed may affect the defoaming effect.

4. Continuous dripping and intermittent addition: flexible use

For the situation where the foaming liquid is flowing or circulating, continuous dripping of the defoamer is an efficient method. This method is suitable for continuous processes in chemical production and can continuously and effectively control foam. At the same time, precise control of the dripping speed and amount through the metering pump can also effectively avoid waste of resources.

On the other hand, intermittent addition is more flexible for scenarios where foam is generated irregularly. By diluting the defoamer first and replenishing it at any time when foam is generated, the regeneration of foam can be effectively controlled.

5. Pay attention to storage and use details

The storage conditions of the defoamer should not be ignored either. It should be kept in a cool and dry place, away from direct sunlight and high temperature to prevent performance degradation. Especially silicone defoamers are very sensitive to temperature changes, and a suitable storage environment helps to maintain their activity and effect.

Conclusion

Mastering the correct use of defoamers can not only effectively solve the foam problem, but also improve production efficiency and product quality. By choosing the right defoamer, accurately controlling the addition amount, flexibly using the addition method, and paying attention to storage details, companies can easily control the foam during the production process and ensure smooth production.
