(sodium hedp)
Sodium HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid) has emerged as a high-efficiency scale inhibitor with 82% higher chelation capacity than traditional phosphonates. As the sodium salt of polyaspartic acid derivatives, it demonstrates exceptional thermal stability (up to 225°C) and pH tolerance (2-12), making it indispensable for:
Third-party testing reveals sodium HEDP's 86% biodegradation rate within 28 days (OECD 301D), outperforming ATMP (43%) and EDTMP (51%). Key technical parameters:

(sodium hedp)
A: Sodium HEDP is widely used as a scale and corrosion inhibitor in water treatment systems, particularly in cooling and boiler water applications. It also acts as a chelating agent in detergents and cleaning formulations. Its stability under high temperatures and pH variations makes it ideal for industrial processes.
A: Sodium HEDP is considered low-toxicity and biodegradable under specific conditions, complying with environmental regulations. However, its dosage must be controlled to avoid excessive phosphorus discharge. Always follow local guidelines for safe usage.
A: Sodium HEDP is a phosphonate-based compound for scale inhibition, while Polyaspartic Acid Sodium Salt is a biodegradable polymer used for dispersing minerals. The latter is preferred in eco-sensitive applications. Both enhance water treatment but function differently.
A: Yes, Polyaspartic Acid Sodium Salt is a green alternative to phosphonates like Sodium HEDP due to its biodegradability and low environmental impact. It effectively inhibits calcium carbonate and sulfate scales. Adoption depends on system requirements and regulations.
A: Sodium of Polyaspartic Acid is used in agriculture as a fertilizer additive, in water treatment for scale control, and in detergents for reducing mineral buildup. Its biocompatibility also makes it suitable for biomedical applications. Versatility drives its cross-sector adoption.
