摘要

摘要: 造浆率是勘探行业用膨润土的主要技术指标,利用实验手段确定膨润土的造浆率指标时,事先需要进行大量的摸索性实验工作。由于受检土样技术参数不明确,实验人员操作经验存在差别,导致操作过程的盲目性很大,特别是人工处理实验数据的过程会造成明显误差,致使造浆率指标的测定过程比较繁琐,准确度不高,方法的可操作性较差。室内实验结果表明,利用Excel的趋势线拟合功能能够有效消除上述各环节中存在的误差,并且可以从根本上消除实验过程中的盲目性。实验数据的验证过程证实,以拟合趋势线方程计算得到的膨润土含量为基准配制悬浮液,测得的Fann35黏度计读数与理论值十分吻合,表明该方法可以快速而准确地确定膨润土的造浆率。

Abstract: Yield is an important parameter of bentonite.The determination of this parameter is quite complex and time consuming. Lack of known properties of clay samples and difference in laboratory operator's skills play an important role in the success of the determination. Repeatability of determining the yield of bentonite is poor, and different persons measuring the yield of the same bentonite sample may give different results. It has been found that these problems can be mitigated or even eliminated using Excel's trend line fitting function. Validation of experiment data proves that clay suspension formulated with bentonite determined by the "trend line fitting" function has Fann35 readings closely agree with theoretical values, indicating that this method of yield determination is accurate and efficient.
