¡ö Properties:
Polyacrylic acid and its sodium salt
are among the most widely used polycarboxylic
acid chemicals for water treatment
purposes today, they show excellent
inhibition effect for calcium phosphate
scales and have good dispersing effect
for Fe(OH)3 and Zn(OH)2 under high
pH value. When used alone,dosage is
2-8mg/L, preferably 4mg/L. When used
together with organic phosphonate
esters and poly phosphates, they shows
good synergistic effects. When used
in alkaline conditions and high concentration,
No scale is formed during operation.Besides,
disposal of PAA or PAAS will cause
no pollution problem.
¡ö Use::
PAA and PAAS can be used as antiscale
and dispersant in circulation cooling
water systems in power plants, iron
& steel factories, chemical fertilizer
plants, refineries and air conditioning
systems. It can be used as dispersant
in pour-cooling water of iron and
steel plants, and can also be used
together with organophosphines and
zinc salts in circulation cooling
water with high hardness and high
alkality. Dosage of PAA and PAAS should
be in agreement with water quality
and equipment materials.
¡ö Package and Storage:
25kg or 250kg in plastic drum, storage
for one year.

¡ö Properties:
This product is an organic aliphatic
acid polymeride, with average molecular
weight in range of 400-800. No toxicity,
Soluble in water, high chemical and
thermal stability. Since its dissociation
temperature is above 330¡æ, the product
exhibits obvious threshold effects under
high temperature (£¼350¡æ£©and high pH£¨8.3£©level,
It shows good antiscale property against
carbonate and phosphate scales with
effective time as long as 100 hours.
This products can also be used together
with dewatering demulsifiers for crude
oil. In addition, this product shows
certain corrosion inhibition effect,
when used together with zinc salt, effect
will be even better.
¡ö Use:
This product is usually used together
with organic phosphonate at dosage of
2- 5ppm for systems of circulatiion
cooling water, oilfield fill water,
crude oil dewatering and low-pressure
boilers. It has good antiscale and scale
stripping properties with antiscale
rate as high as 98%. When used together
with 1~2ppm of zinc salts, it can effectively
inhibit carbon steel corrosion. The
product can also be used as bleaching
agent in textile industry to reduce
dust content. When used alone or used
together with other organic phosphine,
2~5mg/L is expected, when used as corrosion
inhibitor, 10~20mg/L is expected.
¡ö Package and Storage:
25kg or 250kg in plastic drum, storage
for one year.

¡ö Properties:
This product is a low molecular weight
polyelectrolyte, a copolymer of maleic
anhydride and acrylic acid by different
proportion. Its antiscaling property
is equal to or better than HPMA, and
can bear high temperature (300¡ãC). This
product can chelate bivalence metal
ions, especially effective for calcium
sulfate scale. Also, this product shows
good compatibility with and certain
synergistic effect when used together
with other water treatment chemicals
and exhibits obvious dispersion effect
against silt deposition caused by clay,
sand, and organic materials.
¡ö Use:
This product can replace polyacrylic
acid as alkaline antiscale for industrial
circulation cooling water system in
petrochemical industry, power plant
and metallurgical industry ; When used
as antiscaling dispersant, this product
is especially suitable for windy and
dusty northern China areas and for environments
of excess of high suspended organic
materials.This product can replace HPMA
in medium and low pressure boilers and
steam locomotives. Also, this product
can used as alkaline scale and non alkaline
scale inhibitor for desalinization of
sea water, internal treatment of steam
boiler, railway engine, oil-field water
including oil-well connate brine or
injection fluid co-exists with oil in
primary and secondary recovery of oil
well. Dosage is usually 3~10mg/L.
¡ö Package and Storage:
25kg or 250kg in plastic drum, storage
for one year.

¡ö Properties:
Its antiscaling property and dispersion
property are as excellent as that of
Japanese similar product T-225. This
product shows special antiscaling and
dispersion properties to sludge of calcium
phosphate, calcium carbonate, ferric
oxide and remains of microorganism,
algae, organic and inorganic soils.
It has considerable corrosion inhibition
effects under high temperature, high
pH and high alkali. It has good compatibility
with HEDP and BTA, has good effect to
withhold sediments of zinc and calicum
phosphate.
¡ö Use:
It can be used as anti-corrosion dispersants
for circulation cooling water systems
in environment of alkali and excess
of phosphate. it can also be used as
antiscale and corrosion inhibitor for
oilfield dirty water re-filling. It
can act as dispersant of calcium phosphate
and ferric oxide upon pretreatment filming.
Normally, dosage is 10~30mg/L, when
built with HEDP and BTA to form all
organic alkaline formula, proportion
is 30~50%.

solved in water system, thus improving
whole antiscale and corrosion inhibition
properties. In addition, this product
is the best antiscale and corrosion
inhibitor agent in high condensation
index operation.
