Special Anionic Polyacrylamide For Paper Making - China

price: contact company for price

Polyacrylamide is a linear polymer comprised of monomers

unit with functional groups of amide that adsorb on to the

surface of particles. These particles are bridged together

by the long polymer chain drawing the particles closer

together. This process is called flocculation and is widely

used in wastewater treatment.


FLOCCULATION PAM has the ability to bridge together

particles suspended in solution by an adsorption process.

Polymers often have electrostatic charges that allow for

surface particle neutralization resulting in flocculation.

ADSORPTION AND ADHESION PAM creates reversible covalent

bonds between particle surfaces allowing the particle to

gain size and mass.

FRICTION REDUCTION PAM can effectively reduce fluid

friction in a pipe. The friction loss can be minimized by

50-80% with small amounts of PAM added to a liquid.

THICKENING PAM is used to thicken a variety of sludges

in both neutral and acidic conditions. PAM used for thicken

can have additional structures such as branched and cross-

linked. PAM will hydrolyze at pH values above 10.

When aqueous PAM solutions are mixed with sewage, the active

amide groups on the polymer chain adsorb onto the surface of

suspended material in the sewage and created bridges between

them such that they now begin to exclude water from their

newly formed structure. Once a small particle, now form

larger flocs which can improve sedimentation rates in

clarifiers, floatation rates in DAF systems and water

removal in sludge thickening equipment. PAM is widely used

in domestic sewage treatment, mining tailings pulp & paper

making, petrotextiles, oil sands and

mining industries.

Anionic PAM: It is widely used in waste water treatment of

chemical industry, municipal sewage treatment, such as coal

washing, mineral processing, metallurgy, iron and steel

industry and electronic industry. It is also used in oil

industry to enhance oil recovery which is widely used. In

addition, it can be used as paper additives and textile pulp


Cationic PAM: It is very efficient in usage and has high

dehydration rate. It is used for the waste water treatment

in alcohol factory, monosodium glutamate factory, sugar

factory, beverage factory, tanneries, dyeing and other

fields. It has a better effect to be used together with

inorganic coagulant in particular. It can be used as paper

additives as well.

Non-ionic PAM: It is the most appropriate to use NPAM, when

the sewage is acidic. It is also used as agents for the

textile pulp, paper chemicals, water shutoff agent, and

etc.Because of its non-ionic functional group, PH value and

salts have a little influence on NPAM’s flocculation. In

the neutral or alkaline conditions, the flocculation effect

is not as good as APAM, but better than APAM in acidic


Amphoteric PAM: It can be used in a wide range of PH value.

It can also be used in ore leaching with strong acid or

extract valuable metals from the acid catalyst with metals.

Amphoteric ion is not the mixing of anionic and cationic. It

is applied to all kinds of waste water treatment like oil

contamination, organic sewage, inorganic sewage, complex

sewage with frequently water quality changing and sludge

dewatering. It is also used as paper additives, oilfield

water shutoff agent, and etc.
