| 摘 要： | 粘土被氟硼酸、土酸处理后，阳离子交换容量（CEC）、交换性氢都将降低，且残余酸液还具有一定的降低CEC的能力。实验表明，这是由于酸土反应后，粘土的矿物本性发生了变化，生成了主要成分为石英的“非土”物质。

| Abstract: | When clay mineral has been treated by fluoboric acid and mud acid,cation exchgnge capeity (CEC) and exchange hydrogen ion will be decred,and the Spent acid still has some capability to lower CEC. The reason for this is that the property of clay mineral is changed,and the non-clay product,most of which is silica,is formed in the process of clay with acid. |

| Keywords: | fluoboric acid mud acid clay swelling performance test |
