This product could be used as corrosion
inhibitor in cooling water circulation
system and boiler water. Also, it
is a chelant agent in cyanogen-free
plating industry and a water-softening
agent in printing and dyeing industry.When
used alone, 2~10mg/L is expected.
When built with HPMA by ratio ETDMP:HPMA=1:3,
it can used in water treatment of
low pressure boiler. This product
can also built with BTA, PAAS and
zinc salt.

¡öProperties:
This product shows good stability
under high pH value,hard to be hydrolyzed.
Its low toxicity could be easily turned
out of human body. This product works
effectively under temperature 200¡æ.
It can chelate with Fe¡¢Cu¡¢Al¡¢Zn ions
by forming stable chelating compound,
thus it can dissolve oxidized materials
of these metal surfaces. Its resistance
to acid, alkaki and oxidative chlorine
is better than that of other organophosphines.
Especially, this product has good
antiscale and visible threshold effects.
When used together with other agents,
it showes good synergistic effective
performance.
¡ö Use£º
This product is mainly used in boilers
and heat exchanger pipe-lines as scale
inhibitors and corrosion inbitors.
It can also be used as metal and non-metal
cleaner, and as stabilizer and color
fixing agent in textile blenching
industry. When used as antiscale and
corrosion inhibitor, 5~10ppm is expected,
when used as crrosion inhibitor, 100~200mg/L
is expected. When used as abluent
agent, 1000~2000mg/L is expected.This
product usually used together with
Polycarboxylic antiscale and dispersing
agents .

¡ö Properties::
This product is a popular organophosphine
corrosion inhibibor and a high efficienct
antiscale, it is chemically stable,
difficult to be hydrolyzed, difficult
to be destroyed by acid or alkali,
safety in use, no toxicity, no pollution,
good water solubility and etc. Due
to its including phosphonic and carboxylic
group simultaneously, in systems of
high temperature, high hardness and
high pH, its antiscale property is
better than that of HEDP and ATMP,
similar to that of PBTCA, and hard
to form unsoluble organic calcium
phosphate scale. In addition, it is
a powerful corrosion inhibitor, 5~8
times better than that of HEDP and
EDTMP. When built with polymers of
low molecular weight, its corrosion
inhibition effect is excellent. When
built with dispersant, the effect
of antiscale and corrosion inhibition
is even better.
¡ö Use£º
HPAA could be widely used as antiscale
and corrosion inhibitor in circulation
cooling water system for steel &
iron, petro-chemitry, power plant
and medical industry. It is an excellent
antiscale and corrosion inhibitor
for cooling water system when built
with zinc salt. It is especially suitable
for low hardness water in south China.
