HPAM/Cr^(3+)体系交联机理及HPAM/XL耐温抗盐性

Crosslinking mechanism of HPAM/Cr^(3+) system and temperaturesalt resistance of HPAM/XL.

研究了HPAM /Cr3 + 体系的交联机理 ,认为部分水解聚丙烯酰胺参与交联的基团是羧基。通过粒度分析 ,研究了交联体系的交联过程 ,提出了聚合物交联的分子球理论。利用该理论对HPAM /XL交联体系的耐温。

The crosslinking mechanism of HPAM/Cr 3+ system is studied. It is considered that the group taken part in the crosslinking in the partial HPAM is carboxyl. The crosslinking process of the system is studied and molecular ball theory of the crosslinking for polymer is advanced by the particle size analysis. The temperaturesalt resistance and shear restoration of the HPAM/XL crosslinking system are made preliminary analysis using this theory.
