A: Zn HEDP is a zinc-containing hydroxyethylidene diphosphonate used as a corrosion inhibitor and scale inhibitor. It is commonly applied in industrial water treatment and cooling systems. Its chelating properties help stabilize metal ions in aqueous solutions.
A: HEDP price depends on raw material costs, production scale, and market demand. Purity levels and regional supply chain dynamics also impact pricing. Seasonal fluctuations in industrial activity may cause temporary price variations.
A: Polydisperse HEDP contains molecules of varying molecular weights, affecting its solubility and reactivity. This diversity can enhance performance in complex water treatment scenarios. However, it may require tailored dosing compared to monodisperse formulations.
A: HEDP effectively prevents scale formation and corrosion in pipelines and boilers. It works synergistically with other water treatment chemicals under high temperatures and pH variations. Its biodegradability and low toxicity make it environmentally preferable.
A: HEDP exhibits high thermal and chemical stability, ensuring long-term efficacy. However, extreme pH levels or microbial activity may reduce its effectiveness. Regular monitoring and replenishment are recommended for optimal performance.
