Structural Formula
Polyamino Polyether Methylene Phosphonic Acid is a new type of water treatment agent with high chelation and dispersion effects, a high value of calcium tolerance, and good scale inhibition effects. It can be used as a scale and corrosion inhibitor in circulating cooling water systems and oilfield refill water systems, especially under conditions of high hardness, high alkalinity, and high pH values. Polyamino Polyether Methylene Phosphonic Acid(PAPEMP) has excellent scale inhibition abilities against calcium carbonate, calcium sulfate, and calcium phosphate. It can efficiently inhibit the formation of silica scale and stabilize metal ions such as Zn, Mn, and Fe.
Polyamino Polyether Methylene Phosphonic Acid(PAPEMP) can be used as a scale inhibitor for reverse osmosis systems and multistage flash vaporization systems, which often encounter high salt concentrations, high turbidity, and high temperatures (such as high temperature and high turbidity in coal vaporization systems). It can also serve as an accessory agent for woven & dyeing processes (for example, as a yellow turnback inhibition agent), and as an alternative to EDTA, DTPA, and NTA.
