Direct addition: the defoamer is added directly to the system that produces the foam. This method is suitable for systems where foam generation is stable and easily accessible.

Add after dilution: For some high concentration defoamer, it may be necessary to dilute it before adding it to the system. Dilute to choose the appropriate solvent, and fully stir evenly.

Batch addition: If the foam production is more sustained and large, the defoamer can be added in batches to maintain the defoaming effect.

Online addition: In the process of continuous production, the defoamer can be continuously added to the system online through special equipment.

Note:

Select the appropriate defoamer: According to the nature of the foam system, such as pH, temperature, viscosity, composition, etc., choose the Type of defoamer that is suitable for it.

Control dosage: Too little dosage may not reach the antifoam effect, too much dosage may bring side effects, such as affecting product performance, precipitation and so on. It is generally necessary to determine the best dosage by testing.

Stir evenly: After adding the defoamer, it should be fully stirred so that it is evenly distributed in the system.

Pay attention to the timing of addition: Adding defoamer before or at the beginning of the foam is usually better.

Avoid over-dilution: Over-dilution may reduce the effectiveness of the defoamer.

Storage conditions: The defoamer should be stored in a cool, dry, well-ventilated place, away from direct sunlight and high temperature environments, some defoamer may require special storage conditions, such as refrigeration.

Safety protection: Wear appropriate protective equipment, such as gloves, goggles, etc., to avoid direct contact with skin and eyes.

Compatibility test: Before large-scale use, a small-scale compatibility test is conducted to ensure that the defoamer will not have adverse reactions with other components in the system.

Environmental compliance: Select defoamer that meets environmental protection requirements to avoid environmental pollution.
