Sodium HEDP: Revolutionizing Water Treatment Chemistry

As a high-performance corrosion and scale inhibitor, sodium hedp
(1-Hydroxy Ethylidene-1,1-Diphosphonic Acid Sodium Salt) demonstrates 73% better stabilization efficiency compared to conventional phosphonates. Industry reports indicate a 9.2% annual growth in demand since 2020, driven by its synergistic compatibility with polyaspartic acid sodium salt formulations. This compound achieves 98.5% calcium carbonate inhibition at 5-10ppm concentrations across pH 8-11 environments.

Technical Advantages Over Traditional Corrosion Inhibitors

Sodium HEDP exhibits three key technical superiorities:

Thermal stability up to 220°C vs. 180°C for ATMP counterparts
60% lower phosphorus content than HEDP acid formulations
Compatibility with chlorine dioxide (up to 15ppm residual)

Field tests in power plant cooling systems show 42% longer equipment lifespan when using sodium of polyaspartic acid blends compared to orthophosphate-based treatments.
