Sodium HEDP: A High-Efficiency Scale Inhibition Solution

Sodium HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid) demonstrates 92% scale inhibition efficiency at concentrations as low as 2-5 ppm, outperforming conventional phosphonates. As the sodium salt of polyaspartic acid derivatives, this compound combines thermal stability (up to 200°C) with exceptional chelation capacity (CaCO₃ binding: 450 mg/g). Market data reveals a 17.3% CAGR growth in industrial applications since 2020, driven by its dual functionality as corrosion inhibitor and dispersant.

Technical Advantages Over Traditional Corrosion Inhibitors

Comparative analysis shows sodium HEDP provides:

38% longer equipment lifespan vs. orthophosphate-based inhibitors
72-hour sustained pH stabilization (8.5-9.2 range)
0.02 mm/year corrosion rate in steel pipelines (ASTM G31 standard)

The polyaspartic acid sodium salt structure enables biodegradation rates exceeding 80% within 28 days, addressing environmental concerns associated with persistent organic pollutants.
