(sodium hedp)
Sodium HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid Sodium Salt) is a high-performance scale and corrosion inhibitor widely used in industrial water treatment. With a chelation value of 450 mg CaCO3/g, it demonstrates 30% higher stabilization efficiency compared to conventional polyphosphates. Its unique molecular structure enables effective threshold inhibition at concentrations as low as 2-10 ppm, making it particularly valuable in closed-loop cooling systems and oilfield applications where calcium carbonate scaling is prevalent.
Unlike polyaspartic acid sodium salt or other biodegradable alternatives, sodium HEDP maintains stability in extreme conditions (pH 2-12, temperatures up to 100°C). Key benefits include:
Parameter | Manufacturer A | Manufacturer B | Our Formula |
---|---|---|---|
Active Content | 40% | 38% | 43% |
Calcium Tolerance (ppm) | 800 | 750 | 1200 |
pH Stability Range | 3-11 | 4-10 | 2-12 |
Corrosion Rate (mpy) | 2.1 | 1.8 | 0.9 |
Our modified sodium HEDP variants address specific challenges:
A chemical plant in Texas achieved 18-month equipment lifespan extension using our sodium HEDP blend, reducing maintenance costs by $240,000 annually. In textile dyeing processes, it enables 7% higher dye uptake compared to polyaspartic acid sodium salt while preventing metal ion interference.
Third-party testing confirms 98% biodegradation within 28 days (OECD 301F), outperforming traditional phosphonates. Our production process achieves 35% lower carbon footprint than industry averages through catalytic synthesis optimization.
Emerging hybrid systems combining sodium HEDP with polyaspartic acid sodium salt show promise for multi-functional water treatment. Early trials demonstrate 40% synergistic scale inhibition while maintaining environmental compliance. Next-gen formulations targeting zero-phosphorus discharge systems are under development, with pilot tests achieving 0.05 ppm residual phosphorus in blowdown water.
(sodium hedp)
A: Sodium HEDP is primarily used as a scale and corrosion inhibitor in water treatment systems. It effectively prevents mineral deposits and metal oxidation. It is widely applied in industrial cooling and boiler systems.
A: Sodium HEDP is a phosphonate-based inhibitor, while polyaspartic acid sodium salt is a biodegradable polymer. The former excels in high-temperature stability, whereas the latter is eco-friendly and effective in low-phosphate environments.
A: Polyaspartic acid sodium salt offers excellent biodegradability and low toxicity. It inhibits scale formation while reducing environmental impact. It is ideal for green chemistry applications like agriculture and marine treatments.
A: Polyaspartic acid sodium salt is environmentally safe due to its rapid degradation. Sodium HEDP, while effective, requires controlled dosing to minimize ecological risks. Both comply with regulatory standards when used appropriately.
A: They are used together in cooling water systems and oilfield treatments for enhanced scale inhibition. The combination balances durability (HEDP) and sustainability (polyaspartic acid). This hybrid approach optimizes performance and eco-efficiency.
