摘　　要：壁面滑移的机理非常复杂,为检测材料表面能对污泥壁面滑移的影响机理,采用AR2000旋转流变仪在稳态模式下进行试验探究。从扫描曲线分析可知,当剪切应力一定时,滑移速度不依赖于间距,但是改变夹具材质时相对应滑移速度发生改变。试验结果表明:在不锈钢夹具下滑移速度最大、铝夹具最小,铜夹具滑移速度居于两者之间。In order to test the effect of material surface energy on sludge wall slip,AR2000 rotary rheometer was used to conduct shear test in steady state.According to the analysis of the scanning curve,when the shear stress is constant,the slip velocity does not depend on the spacing,but changes with the material of the fixture.The results show that the slip velocity of stainless steel plate is the largest and that of aluminum plate is the smallest,and the slip velocity of copper plate is between the two.
