Defoamer FAQ Section
Q: How does a defoamer work to eliminate foam?
A: Defoamer works by destabilizing foam bubbles through three main mechanisms: spreading on the foam film surface, penetrating the foam lamella, and bridging between bubbles. The active ingredients in defoamers reduce surface tension and disrupt the foam structure, causing bubble coalescence and collapse.
Q: What factors should be considered when selecting a defoamer?
A: Key factors include system compatibility, temperature range, pH conditions, shear stability, regulatory requirements, and the nature of the foaming system. Our technical team can help select the optimal defoamer formulation based on your specific application requirements.
Q: How should defoamer be stored and handled?
A: Defoamers should be stored in their original containers at temperatures between 5°C and 40°C, protected from freezing and direct sunlight. Avoid contamination and keep containers tightly closed when not in use. For best results, gently agitate or mix before use if separation occurs during storage.
