Understanding Sodium HEDP in Modern Industrial Chemistry

Sodium HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid) has emerged as a high-performance scale and corrosion inhibitor, demonstrating 68% higher efficiency than traditional phosphonates in cooling water systems. As the sodium salt of polyaspartic acid derivatives, it combines thermal stability (up to 200°C) with exceptional calcium ion tolerance (300 ppm), making it indispensable for industrial water treatment.

Technical Superiority in Corrosion Prevention

Third-party testing reveals sodium HEDP achieves 92-95% corrosion inhibition rates in steel pipelines at 50 ppm concentration, outperforming ATMP (85%) and HEDP acid (88%). Its unique molecular structure enables:

pH stability across 2-12 ranges
Biodegradation rate of 81% within 28 days
Zero phosphorus discharge in closed-loop systems
