Defoamer dosage must be dynamically adjusted based on system characteristics. Chemi Tech defoamers, with scientifically formulated active components, adapt to diverse industrial challenges.
1. Key Parameters for Dosage Control
System Type: Aqueous systems require 0.01%-0.05% dosage, while oily systems need 0.1%-0.3% to counteract higher surface tension.
Foam Severity: Gradually increase dosage in high-foam scenarios, observing suppression duration for optimal adjustment.
2. Applications in Complex Systems
High-Viscosity Fluids: In coatings or adhesives, pre-dilute defoamers to 5%-10% and use high-pressure injection or metering pumps to avoid cratering.
Multiphase Systems: Incorporate hydrophobic particles (e.g., silica) to enhance adsorption efficiency, reducing dosage by 20%-30%.
3. Dynamic Adjustment and Equipment Compatibility
Automated Dosing Systems: Install foam sensors linked to metering pumps in large reactors, achieving on-demand dosing and saving 15%-20% in usage.
Dispersion Equipment Optimization: Use high-shear homogenizers (≥2000 rpm) to ensure uniform dispersion and prevent oiling or turbidity.
