Sodium HEDP and Its Role in Modern Industrial Solutions

As a high-performance scale inhibitor, sodium HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid Sodium Salt) demonstrates 94% scale inhibition efficiency at concentrations as low as 2-5 ppm in circulating water systems. This organophosphonic acid compound outperforms traditional phosphates by offering simultaneous corrosion and scale inhibition across pH 2-12 environments. Its molecular stability at temperatures up to 225°C makes it particularly valuable in extreme industrial conditions.

Technical Superiority in Chelation Chemistry

Comparative testing reveals sodium HEDP's calcium carbonate inhibition rate reaches 98.3% versus 82.7% for ATMP (Amino Trimethylene Phosphonic Acid) under identical conditions. Key performance metrics:

Parameter	Sodium HEDP	Polyaspartic Acid Sodium	EDTA-4Na
Chelating Value (mgCaCO3/g)	450	380	280
Thermal Stability (°C)	225	180	120
Biodegradability (%)	78	92	0
