| 摘 要： | 对经过改性处理之后的普通石英砂的润湿性能进行了研究。实验采用滴水穿透时间法（WDPT）、酒精溶液入渗法（MED）、接触角测定法三种方法。通过这三种方法来定性和定量地描述其润湿性能。实验结果表明：直接经过酸化处理的石英砂与经过硅烷化处理的石英砂的润湿性能有着明显的改变,前者较普通石英砂表现更为亲水,而后者表现出斥水性。此研究为用石英砂模拟不同润湿性能土壤提供了表面改性方法以及前期的理论准备。

| Abstract: | The wettability of surface modified quartz sand was studied by water drop penetration time（WDPT） method,molarity of an ethanol droplet（MED） and contact angle measurements.The wettability of acidified and silanized quartz sand were analyzed qualitatively and quantitatively.Under acid or silane treatment,the wettability of quartz sand changed markedly.The surface of acidified and silanized quartz sand showed more hydrophilic and hydrophobic than that of the unmodified quartz sand,respectively.This study for using quartz sand to simulate different wetting properties of the soil provides a surface modification method. |
