occulation effect.
2, adhesiveness, can pass the mechanical, physical, chemical, bonding effect.
3, drag-reducing: PAM can effectively reduce the friction resistance of fluid, the water add trace PAM would drag reduction of 50-80%.
4, thickening: PAM under the condition of neutral and acid are thickening effect, when the PH value in more than 10 ℃ PAM easy to hydrolysis.Half the reticular structure, thickening will be more obvious.
