USAGE
Mud
dehydrating agent:
activated-sludge method
normally can be used to process urban and industrial sewage water,
biochemistry mud is normally colloid with strong hydrophilicity,
has high organic content, and is difficult to dewater.
Cationic-polyacrylamide can be used to process, has small dosage
and high dewatering efficiency, and is easy to separate.
Paper-making
adhesive:
In the paper making industry, the
product can directly generate static bridging effect with inorganic
salt ions, fiber and other organic organic polymers for achieving
the effects of intensifying the physical intensity of paper,
reducing fiber or cationic PAM paper reinforcing agent, being a
water soluble cationic polymer containing carbamyl and the like,
and the product can effectively improve the paper intensity, reduce
loss of fiber and filler, and accelerate water filtration, and has
the effects of intensifying, residency and filtration assistance.
The product also can be used in white water treatment and has the
prominent effect of flocculation in deinking process.
Treatment of Sewage Water and
Organic Waste Water:
the product shows
electropositivity in acid or alkaline media, thereby the product is
extremely effective for flocculation, sedimentation and
disambiguition of sewage water whose suspended particulates are
provided with negative charge such as waste water of alcohol plant,
waste water of brewhouse, waste water gourmet powder factory, waste
water of sugar making plant, waste water of manufactured meat
plant, waste water of beverage factory, waste water of printing
& dyeing mill, and the like. The effect of using
cationic-polyacrylamide is several times or dozens of times better
than using anionic-polyacrylamide, nonionic- polyacrylamide or
inorganic salt since the waste water is generally provided with
negative charge.
Used as water treatment
flocculation agent of tap water plants with rivers as water
sources:
The product has small dosage,
excellent effect and low cost, the effect is better when it is
matched with organic flocculation agent particularly. It will
become highly-effective flocculation agent for water plants on the
river basins of Yangtze River, Yellow River, Huaihe River and other
rivers.
Oil field chemical
agent:
It can be used as
anti-clay-swelling agent, thickening agent for oilfield
acidification, and the like.

USAGE
Oil-displacing agent of oil field tertiary
oil recovery:
It can adjust the rheology of
filled water, increase the viscosity of driving liquid, improve
water drive wave and efficiency, lower water phase permeability in
ground layer, and enable water and oil to flow forward at even
speed. Its effect is that it is mainly used in tertiary oil
recovery of oil fields in the aspect oil production, and raw oil of
about **0 to **0ton more can be produced through filling the
macromolecule polyacrylamide product one ton.
Well drilling mud raw
materials:
in oil field exploration and
development and exploration of geology, water and coal, it is used
as adhesive of well drilling mud raw materials, can improve the
service life of drill bits, improve the drill speed and drilling
footage, and reduce plug in replacing drill, and has prominent well
slough preventing effect, and it can be used as fracturing fluid of
oil fields or plugging agent of controlling profile and plugging
water.
Industrial Waste Water
Treatment:
Water sources of many tap water
factories in China come from rivers, the sand and mineral contents
are higher, water is muddy, the water still can not achieve demands
although passing through sedimentation and filtration, and
flocculating agent needs adding; however huge adding amount
generates increased mud amount and bad effect. The adding amount is
only 1/*0 of inorganic flocculating agent if anionic-polyacrylamide
is adopted as flocculating agent, but the effect is several times
better than the organic flocculating agent, and even dozens of
times. If the river water with severe organic matter pollution can
be matched with anionic-polyacrylamide for use, the effect will be
better.
Paper-making
adhesive:
The product can be used as fining
agent, residency agent, filtration aid and paper dry and wet
intensity reinforcing agent in paper-making industry.
