  • 摘要: 针对橡胶接触界面间液体渗入特性及力学驱动机制,采用自建原位观测仪,得到橡胶-玻璃接触界面间液体(丙酮与水混合液,体积比1∶1)渗入过程.利用自编MATLAB程序及图像软件,得出橡胶-玻璃接触界面间压力与真实接触面积比关系曲线、界面内液体渗入特性及固-液界面润湿性对界面内液体渗入面积比的影响.研究表明:对于橡胶-玻璃接触界面,压力与真实接触面积比呈幂函数规律变化,液体在接触界面内的渗入路径大多出现在接触面积比较大区域;驱动液体铺展的毛细管力与阻碍液体铺展的固-液黏性阻力之间的平衡关系,是界面液体渗入特性的主要力学机制,也是决定液体铺展速度的因素.另外,实验结果表明,液体渗入面积比随固-液界面润湿性的增强而增大.该研究为橡胶接触界面的摩擦、润滑及密封机理研究奠定了一定的理论基础.
