Anionic polyacrylamide(APAM) series products are water-soluble linear polymers
synthesized with high polymerization degree, easily soluble in water, almost
insoluble in benzene, ether, lipids, acetone and other general organic
solvents.

The anionic polyacrylamide produced by Xinhuan Water Treatment can be used as
coagulant aid, retention agent, sludge dewatering agent and coagulation
precipitant. Because its molecular chain contains a certain number of polar
groups, it can adsorb the suspended solid particles in water, make the bridge
between particles or make the particles coalesce to form large flocs through
charge neutralisation, so it can accelerate the settlement of the particles in
the suspension, and it has the effect of accelerating the clarification of the
solution and promoting the filtration, etc.

Anion Polyacrylamide is mainly used to purify drinking water and domestic
sewage, purify industrial sludge and dewatering agent and coagulation and
sedimentation agent. It is mainly used to purify drinking water and domestic
sewage; purify industrial water and industrial wastewater; purify mine and
oilfield re-injection water; purify papermaking, electroplating, electronics,
dyeing and finishing, pharmaceuticals, metallurgy, coal washing, tannery and
various chemical wastewater. The most suitable type of product should be
selected according to the conditions and water quality of the system to be
treated.

Usage and precautions:

1、Anionic polyacrylamide can not be directly added to the sewage, it must be
dissolved in water and treated with its aqueous solution before use.

2、The water used to dissolve the granular polymer should be clean water (such
as tap water), not sewage. Room temperature water can be used, usually without
heating. When the water temperature is lower than 5 ℃, the dissolution rate is
very slow. As the water temperature rises, the dissolution rate will
accelerate, but above 40 °C, the polymer degradation rate will accelerate,
thus affecting the use effect. Generally speaking, tap water is suitable for
preparing polymer solutions. Strong acid, strong alkali, high salt water is not
suitable for preparation.

3、Fully dissolved. When dissolving, the water should be stirred sufficiently,
and then add the powder slowly and evenly to prevent large flocs and fish eyes
from clogging pipes and pumps.

4、Stirring speed is generally 200 rpm, and the time is not less than 60
minutes. Appropriately increase the water temperature 20-30 ℃, can accelerate
the dissolution. The maximum temperature of the liquid should be less than 60
℃.

5、Determine the dosage. The concentration of anionic polyacrylamide solution
is recommended to be 0.1%-0.3%, i.e., add 0.1g-0.3g of polymer powder to 1
litre of water. Determine the dosage by experiment before use. If the dosage is
too small, it will not work. If the dosage is too large, PAM will not
flocculate, but disperse and stabilise.

6、Wash the work site with water frequently to keep it clean. Because of the
viscosity of PAM, the surface of PAM scattered in the well is smooth when it
meets water, which can prevent the operator from slipping and causing safety
accidents.
