PAPEMP
(Polyamino
Polyether Methylene Phosphonate)
Identification
Synonyms:
CAS No.:
Structural Formula:
M.W.: around 600
Application
A
new generation of water treatment agent with
very good chelating
and dispersion ability, high calcium
resistance ability, and excellent antiscale
dispersion effects. Widly used as anti-scale
and corrosion inhibitor in
circulating cool water system, oilfield refill water system in
condition of high hardness, high
alkali and high pH value to prevent formation of calcium
scale, silica scale, and stabilize such metal ions
as Zn, Mn and Fe. PAPEMP can also be
used in prefilming antiscale agent in inverse
osmosis system and in 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),
auxiliary for weave, dyeing and papermaking
as substitute for EDTA, DTPA and NTA.
