摘要
研究了粘土在单一碱（Ｎａ２ＣＯ３）盐水溶液和复合碱（Ｎａ２ＣＯ３与ＮａＯＨ的等摩尔混合物）盐水溶液中的膨胀行为，探讨了碱的类型和浓度变化引起粘土膨胀差异的机理。研究结果表明，粘土在碱溶液中的膨胀率随碱浓度的增加先增大后降低；粘土在复合碱溶液中的膨胀性比在单一碱溶液中的小；
The procedure of polymerization of methacrylamidoxyethyltrimethylammonium chloride (MOTAC), acrylic acid (AA) and acrylamide (AM) is presented and the terpolymer synthesized is evaluated in laboratory for filtrate loss reducing ability in various clay muds, tolerencies to NaCl and calcium salts, heat resistance and shale inhibition. All these performance properties of the terpolymer as filtrate loss reducer are good.
