【摘要】 研究了HPAM和金属离子Ti⁺⁴、Mn⁺⁴、Cr⁺³、Zr⁺⁴、Al⁺³、Fe⁺³交联冻胶的性能,讨论了PAM水解度、pH值、温度和无机盐对交联冻胶性能的影响,给出了不同冻胶的成胶条件。指出Cr⁺³冻胶的抗盐、抗剪切能力强,但抗温能力较差;Ti⁺⁴、Zr⁺⁴冻胶是一种性能优良的冻胶。更多还原

【Abstract】 The study on properties of HA PM and its gel cross-linked by Ti⁴⁺,Mn⁴⁺,Cr³⁺,Zr⁴⁺,Al³⁺ and Fe³⁺ was conducted. The influence of hydrolyzing degree,pH,temperature and inorganic salts on cross-linked gel properties was investigated and the conditions of the gel formation were also determined. It pointed out that the gel cross-linked by Al³⁺ has potential resistance to salt and to shear,but low resistance to temperature;the gels treated with Ti⁴⁺ and Zr⁴⁺ are gels with good properties.更多还原
