Structural Formula:
Properties:
This product has structural features of both phosphonic acid and
carboxylic acid group, which enable its excellent antiscale
corrosion inhibition properties. Its antiscale property under
high temperature is far better than that of organophosphines.
It can also improve the solubility of zinc salt, has good
chlorine oxidation resistance and good composite synergy.

Usage:
This product is the widely used high effective agent as
composite antiscale corrosion inhibitor, it is also the
excellent stabilizer for zinc salt. It is widely used in
circulating cool water system and oilfield refill water
system as antiscale corrosion inhibitor, especially
suitable to use together with zinc salt and copolymer.
It can be used in situations of high temperature, high
hardness, high alkaline and high index of condense
multiples, it is used as chelating agent and metal
detergent in lavation fields.
This product is usually used together with zinc salt,
copolymer, organophosphine, imidazole and other water
treatment agents.
