1、產品性能Product performance
PAPEMP為一代水處理劑，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，它不僅有效抑制碳酸鹽，硫酸鹽水垢，鋅垢，和硅垢的生長，而且可以抑制磷酸鹽垢，同時可有效地抑制硅垢的形成，特別適用于高硬度、高堿度、高pH的循環冷卻水系統和油田水處理。且具有良好的穩定金屬離子如鋅、錳、鐵的作用。 PAPEMP用于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。
PAPEMP, a new type of water treatment agent, has high chelation and dispersion effects, high value of calcium tolerance, and good scale inhibition effects. It not only has excellent scale inhibition ability to calcium carbonate, calcium sulfate, zinc scale and calcium phosphate, and efficiently inhibits the formation of silica scale, especially suitable in circulating cool water system and oilfield refill water system in situations of high hardness, high alkalinity and high pH value, but as well as stabilizes metal ions such as Zn, Mn and Fe. PAPEMP can be used as scale inhibitor for reverse osmosis system and multi-step 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 turn-back inhibition agent）, as alternatives of EDTA, DTPA and NTA .
