Defoamer Selection and Process Compatibility in Industrial Applications

Defoamer selection must align with system characteristics:

pH & Temperature: Non-silicone defoamers are preferred for acidic (pH 1.5-2.5) or high-temperature (55-80°C) environments to avoid phase separation36.

Ionic Strength: Hydrophobic group design enables rapid interface disruption in high-metal systems (e.g., Fe³⁺ 50-80g/L)18.

Chemi Tech's solutions offer:

Customized Molecular Design: Triazine ring structures via esterification-substitution synthesis enhance chemical inertness in sulfate systems16.

Dynamic Adaptation:

Leaching Phase: High-permeability formulas minimize particle entrapment.

Extraction Phase: Compatibility with organic phases (e.g., kerosene) improves phase separation by 15-20%36.

Case studies demonstrate:

In lateritic nickel ore processing, 0.05% defoamer dosage increases scandium recovery to 92% with impurity entrainment below 0.3%16.

For vanadium-titanium magnetite, defoamers tolerate Fe³⁺ 80g/L, achieving 40% higher efficiency without emulsion thickening38.
