EDTMPS is a nitrogen-containing organic phosphonate that serves as an advanced cathodic corrosion inhibitor, demonstrating 3-5 times greater efficiency than conventional inorganic polyphosphates. This water-soluble, environmentally friendly compound exhibits exceptional chemical stability and thermal resistance, maintaining effective scale inhibition performance at temperatures up to 200°C. Its unique molecular structure allows dissociation into eight ions in aqueous solution, enabling superior chelation with multiple metal ions and formation of complex macromolecular networks that effectively disrupt normal scale crystallization processes. EDTMPS demonstrates particular effectiveness against calcium sulfate and barium sulfate scales.
Superior Corrosion Inhibition: Cathodic protection with 3-5x efficiency of inorganic polyphosphates
Excellent Scale Prevention: Effective against carbonate, sulfate, and barium scales
High Thermal Stability: Maintains performance at temperatures up to 200°C
Multi-Functional Application: Combines scale inhibition, corrosion control, and chelation properties
Environmental Compatibility: Non-toxic and readily biodegradable
Enhanced Solubility: Excellent water solubility for easy application
Synergistic Performance: Compatible with various water treatment formulations
