氨基三亞甲基膦酸 (ATMP)

 

產品概述

氨基三亞甲基膦酸（Amino Trimethylene Phosphonic Acid，簡稱 ATMP）是一種有機磷酸鹽類化合物，CAS 號為 6419-19-8，分子式為 N(CH₂PO₃H₂)₃，相對分子質量為 299.05。

性能與用途

ATMP 具有良好的螯合、低限抑制及晶格畸變作用，可有效阻止水中成垢鹽類形成水垢，特別是碳酸鈣垢的形成。本產品在水中化學性質穩定，不易水解，在水濃度較高時具有良好的緩蝕效果，其鈣螯合值可達 300 mg/g。

ATMP 廣泛應用於火力發電廠、煉油廠的循環冷卻水、油田回注水系統，可減少金屬設備或管路腐蝕和結垢。同時，ATMP 在紡織印染等行業用作金屬離子螯合劑，也可用於金屬表面處理劑。ATMP 的中性鈉鹽形式（ATMP·Na₄）適用於中性到酸性配方，特別適合火力發電廠、煉油廠的循環冷卻水和油田回注水系統；ATMP 的部分鉀鹽溶液（ATMP·Kx）具有比鈉鹽更高的溶解度，尤其適合油田回注水系統。

ATMP 固體為結晶性粉末，易溶於水，易吸潮，便於運輸和使用，尤其適用於冬季嚴寒地區。

技術指標

本品符合 HG/T 2841-2005 及 HG/T 2840-2010 標準，外觀為無色或淡黃色透明液體或白色顆粒狀固體，活性組分含量 ≥50.0%（液體）或 ≥93.0%（固體）。

使用方法

ATMP 常與其他有機膦酸、聚羧酸或鹽等復配成有機水處理劑，用於各種不同水質條件下的循環冷卻水系統。用量以 1~20 mg/L 為佳；作緩蝕劑使用時，用量為 20~60 mg/L。

包裝與貯存

液體用塑料桶包裝，每桶 25 kg 或 250 kg；固體用內襯聚乙烯袋的塑料編織袋包裝，每袋淨重 25 kg。貯於室內陰涼通風處，防潮、嚴防曝曬，貯存期十二個月。

安全防護

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

Polyamino Polyether Methylene Phosphonic Acid

  PAPEMP is a new kind of water treatment agent. PAPEMP has high chelation and dispersion effects, high value of calcium tolerance, and good scale inhibition effects. PAPEMP can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system in situations of high hardness, high alkali and high pH value. PAPEMP has excellent scale inhibition ability to calcium carbonate, calcium sulfate and calcium phosphate. PAPEMP can efficiently inhibit the formation of silica scale, stabilize metal ions such as Zn, Mn and Fe. PAPEMP can be used as scale inhibitor for reverse osmosis system and multistep flash vaporization system in which high salt concentration, high turbidity and high temperature are usually encountered (such as high temperature and high turbidity in coal vaporization system), accessory agent for woven & dyeing (for example, yellow turnback inhibition agent), as alternatives of EDTA, DTPA and NTA .
