As a new kind of water treatment agent, PAPEMP has high chelation and dispersion effects, high value of calcium tolerance, and excellent scale inhibition effects. PAPEMP can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system, especially in the condition of high hardness, high alkali and high pH value. PAPEMP has excellent scale inhibition ability to calcium carbonate, calcium phosphate and calcium sulfate. It can efficiently inhibit the formation of silica scale, and stabilize metal ions such as Zn, Mn and Fe.
PAPEMP can be used as scale inhibitor for Reverse Osmosis System and multistage 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), textile dyeing auxiliary and papermaking additives (for example, yellowing inhibitor), as alternatives of EDTA, DTPA and NTA, etc.
