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.
