Antiscalant :PAPEMP
Chemical name:Polyamino Polyether Methylene Phosphonate (PAPEMP)
Molecular weight: about 600
Properties of PAPEMP:
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. PAPEMPcan 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 .

結構式：
一、產品性能：
PAPEMP為最新一代水處理劑，具有很高的螯合分散性能和很高的鈣容忍度及優異的阻垢性能，該藥劑可作為循環冷卻水系統的阻垢緩蝕劑，特別適用於高硬度、高鹼度、高pH的循環冷卻水系統和油田水處理。對碳酸鈣、磷酸鈣、硫酸鈣的阻垢性能優異，同時可有效地抑制矽垢的形成，且具有良好的穩定金屬離子如鋅、錳、鐵的作用。 PAPEMP用於反滲透系統的膜阻垢劑，多級閃蒸系統等高含鹽量、高濁度、高溫系統的阻垢和緩蝕（如煤汽化系統高溫高濁水系統的阻垢），紡織印染助劑和造紙助劑（返黃抑制劑），可替代EDTA、DTPA、NTA等。
二、質量指標
| 項 目 | 指 標 |
| 外 觀 | 琥珀色透明液體 |
| 固體含量 % ≥ 45.0 | |
| 活性組份（以PAPEMP計）% ≥ | 40.0 |
