摘要
针对地浸铀矿层的非均质性特点,研究了以部分水解聚丙烯酰胺和柠檬酸铝为原料合成的流体控制剂在地浸矿层中的成胶性能。通过分析交联剂的不同配比及浓度、聚合物的相对分子质量及浓度、模拟地下水矿化度等对流体控制剂成胶性能的影响,确定流体控制剂最优合成条件,保证其有效交联形成弱凝胶。
Aim at the characteristics of ore bed in-situ leaching uranium,the gelling properties of fluid control agent which prepared by hydrolyzed polyacrylamide and aluminum citrate in the ore bed in-situ leaching are studied.According to the analysis of the fluid control agent gelling factors which are different ratio and concentration of cross-linking agent,relative molecular mass and concentration of polymer and simulation of groundwater salinity.In order to ensure them crosslinked efficiently,the optimum synthesis conditions are defined.
