Viscous foam layers (>1.2m thick) in chemical multi-effect evaporators reduce heat transfer by 30% and cause overflow accidents due to surfactants and high salt content (Cl⁻>50,000mg/L). Chemi Tech’s defoamer (KM-8805) delivers:
Nanocarrier penetration: 200nm silicone-polyether particles disrupt foam lamellae;
Charge adaptation: Zeta potential adjusts (±30mV) to resist cation interference;
Thermal resistance: Stable at 250℃ without degradation.
Case study:
A Jiangsu pesticide plant eliminated foam-induced shutdowns with 60ppm KM-8805:
Heat exchange efficiency restored to 92%;
Evaporation capacity increased by 28%;
Annual savings: RMB 2.1 million.
Dosage: 40-80ppm via metering pump.
