By increasing the amount of Na-HA, the kaolinite suspension will transform from non-Newtonian fluid into Newtonian fluid. The order of their activity may be shown as follows: weathered bituminous coal Na-HA> lignite NaNHA> peat, Na-HA. 随着HA-Na添加量的增加,高岭土悬浮液由非牛顿流体向牛顿流体转化,其敏感程度为风化烟煤HA-Na>褐煤NHA(硝基腐植酸)-Na>泥炭HA-Na。
