Industrial & Metalworking
Demulsifiers
FEATURES
General Properties: Polymeric surfactants or polyelectrolytes; typically low-viscosity liquids or water-soluble powders.
Synergistic Role: Dispersants stabilize particles but can also stabilize foam bubbles. The defoamer must rapidly break the foam without causing the dispersed metal fines to agglomerate or settle prematurely.
Performance Benefits:
Improves Filtration: Prevents foam from blinding filters and carrying metal fines out of the filtration system.
Enhances Surface Finish: Keeps metal particles suspended and away from the machining zone, preventing surface scratches.
Rapid Foam Collapse: Overcomes the foam-stabilizing effect of dispersants under high-pressure coolant delivery.
