本文采用静态实验的方法,讨论了不同反应时间、不同矿物及拉度、不同碱浓度条件下,固液比(W_s)对不可逆碱耗结果的影响,同时也讨论了对可逆离子交换碱耗结果的影响。实验结果表明,随着W_s的增大,可逆及不可逆碱耗均是逐渐减小的。蒙脱土的不可逆碱耗受W_s影响的范围比辽河砂岩和石英砂大;当W_s大于0.1时,辽河砂岩及石英砂的结果已不受W_s的影响。石英砂颗粒越小,不可逆碱耗受W_s影响的范围越大。碱浓度越小,不可逆碱耗受W_s的影响也越小,反应时间无论长短,W_s均有较大影响。可逆碱耗受W_s的影响趋势与不可逆碱耗一致,且蒙脱土比高岭土受W_s的影响更大。
In this paper, the effects of solid-to-liquid ratio (W_s) on irreversible alkali consumption were discussed under different reaction conditions, different mineral concentrations and different concentrations of alkali, and the effects of reversible ion exchange on alkali consumption Impact. Experimental results show that with the increase of W_s, the reversible and irreversible alkali consumption decrease gradually. The irreversible alkali consumption of montmorillonite is affected by W_s more than Liaohe sandstone and quartz sand. When W_s is greater than 0.1, the results of Liaohe sandstone and quartz sand are not affected by W_s. The smaller quartz sand particles, the greater the range of irreversible alkali consumption affected by W_s. The smaller the alkali concentration, the less the irreversible alkali consumption is affected by W_s. The reaction time has a great effect on W_s, regardless of the reaction time. The trend of reversible alkali consumption affected by W_s is consistent with that of irreversible alkali consumption, and montmorillonite is more affected by W_s than kaolin.
