2-羥基膦酰基乙酸 (HPAA)

 

產品概述

2-羥基膦酰基乙酸（2-Hydroxy Phosphonoacetic Acid，簡稱 HPAA），CAS 號為 23783-26-8。

性能與用途

HPAA 化學穩定性好、不易水解、不易被酸鹼所破壞；本品使用安全可靠、無毒無污染，能提高鋅的溶解度，具有極強的緩蝕作用，緩蝕性能比 HEDP、EDTMP 高。

HPAA 主要用做金屬的陰極緩蝕劑，廣泛用於鋼鐵、石化、電力、醫藥等行業的循環冷卻水系統的緩蝕阻垢，特別適合用作我國南方低硬度、易腐蝕水質的緩蝕劑。HPAA 與低分子量的聚合物一起組成的有機緩蝕阻垢劑性能優良，與鋅鹽復配效果更佳。

包裝與貯存

用塑料桶包裝，每桶 25 kg 或 250 kg。貯於室內陰涼處，貯存期為十二個月。

安全防護

本品為酸性液體，操作時注意勞動保護，應避免與皮膚、眼睛接觸，接觸後用大量清水沖洗。

Sodium Salt of Polyaspartic Acid

  PASP is a kind of biopolymer materials, of which molecules contains abundant amido bond, carboxyl and other active groups. Amido peptide bond has biological activity and high chemical stability, hard to decompose at high temperature; carboxyl group can be complex with many metal ions in water, which make PASP have high chemical activity in aqueous solution; in each structural unit of PASP , the oxygen and nitrogen atoms can easily form hydrogen bonds with water molecules, it has good hydrophilicity and water solubility. The special molecular structure of PASP ensures that it has good dispersing ability, corrosion inhibiting properties, excellent biodegradability and environmental friendly characteristics.

HEDP: The Eco-Friendly Powerhouse Redefining Industrial Sustainability

 As the global industrial landscape shifts toward sustainability, businesses are no longer choosing between performance and environmental responsibility—they’re demanding both. In this quest for greener operations, Hydroxyethylidene Diphosphonic Acid (HEDP) has emerged as a transformative solution, proving that industrial efficiency and eco-friendliness can go hand in hand. Far beyond its renowned scale-inhibiting and corrosion-resistant capabilities, HEDP’s environmental advantages are rewriting the rulebook for how industries approach chemical management, making it the top choice for forward-thinking companies. The most compelling environmental attribute of HEDP lies in its biodegradability—a game-changer in a market saturated with persistent, eco-harmful chemicals. Unlike traditional phosphates and synthetic inhibitors that linger in waterways for years, breaking down fragile aquatic ecosystems, HEDP undergoes natural degradation under aerobic conditions. Through microbial activ...
