Polyamino Polyether Methylene Phosphonate


Molecular Weight: about 600

PAPEMP is a new kind of water treatment agent. PAPEMP has high chelation and dispersion effects, high calcium tolerance, and good scale inhibition effects. PAPEMP can be used as scale and corrosion inhibitor in circulating cooling water and oilfield water of high hardness, high alkali and high pH value. PAPEMP has excellent scale inhibition ability to prevent 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 textile & dyeing (for example, yellow turnback inhibition agent), as alternatives of EDTA, DTPA and NTA .

The dosage of PAPEMP is 5-100ppm. A difference from other agents is that the more dosage the better.
It can be used with poly carboxylic acid. High dosage can realize high cycles of concentration.

Package and Storage:
Normally in 250kg plastic drum, IBC drum can also be used as required. Storage for ten months in room in shady and dry place.

Safety Protection:
PAPEMP is acidic. Please pay attention to the protection when operating. Avoid contact with eyes and skin. In case of contact with eyes or skin, rinse immediately with plenty of water.
