| 英文摘要 | The properties of solution in the reaction process of low concentration and high molecular weight partially hydrolyzed polyacrylamide(HPAM) and aluminum citrate(AlCit) system are investigated by using viscometer, SEM, nuclear pore membrane, dynamic light scattering and Al-27 NMR. The experimental results show that the viscosity of HPAM/AlCit crosslinking system is decreased with reaction time in lower shear rate and the system is shear thickening in higher shear rate. After crosslinking the spin-lattice relaxation time(T-1) of Al decreases with the reaction time. The linked polymer solution is formed by intra-molecular crosslink of HPAM and AlCit forming linked polymer coil(LPC) in lower concentration of the system. The LPC is a spherical coil with a mean hydrodynamic radius of 238 nm. The ability of the LPS to block the neclear pore film is related to the reaction time of HPAM/AlCit system. |
