Physical property & Characteristics of PAM
a. physical property: (CH2CHCONH2)r
PAM is a linear polymer. It is soluble to water, insoluble to common organic solvents like benzene, ethylbenzene, esters, acetone.
PAM is hygroscopic and the hygroscopicity is correlative to its ionization.
The aqueous solution of PAM is an almost tran***rent thick liquid which is nontoxic and noncorrosive.
PAM is stable to heat up to 100℃. Above 150℃, it decomposes to nitrogen and transmolecular iminization accures, which render it insoluble to water.
The density of PAM is 23℃ 1.302 g/ml, and its vitrification temperature is 153℃. PAM shows non-newton fluid features under stress.
b characteristics
1) flocculation£ºsuspending particles can be flocculated by PAM via charge-patch neutralization or bridging mechanism.
2) adhesive ability
3) friction reduction£ºTrace amount of PAM in water can effectively reduce 50-80% of frictions.
4Thickening£ºPAM possesses thickening ability at acid or neutral condition.
At PH>10, hydrolysis accures, rendering half network structure which enhances the thickening effect.
c mechanism:
1flocculation: When PAM is used to effect flocculation, certain factors should be concerned:
electrokinetic potential on the surface of granules, viscosity, turbidity and PH.
The electrokinetic potential makes granules repulsive to each other.
PAM neutralizes the charges on the surface of the granules and help flocculation.
2) bridging effect£ºGranules can be attached by PAM which takes effect like bridges.
The granules finally go towards aggregates.
3) surface absorption£ºPolar functional groups in PAM can effect surface absorption.
4supporting effect:PAM moleculars connect the dispersed phases via mechanical, physical and chemical forces,
thus forming network structure to support the phases.
Application:
1) In papermaking process, can improve the wet strength ,used for retention aid agent, intensifier.
2) Used for coagulant, flo |
