Foam Control in Acrylic Emulsion High-Speed Mixing

During acrylic emulsion production, high-speed mixing introduces air, causing severe foam. A chemical plant observed 80% foam coverage at 1200rpm agitation, reducing reactor capacity by 35% and causing viscosity fluctuations.

Solution with Chemi Tech Defoamer KM-325:

Emergency defoaming: Direct injection at 0.15‰ dosage reduced foam height from 45cm to 4.5cm within 3 minutes.

Long-term control: Synchronized addition with emulsifier feeding (0.05‰ dosage) suppressed re-foaming.

Results:

Annual output increased by 12,000 tons with no impact on transparency
