Analytical Research of the Mechanical Action in Detergency - Contribution of Holizontal and Vertical Force Component in the Field of Ultra-Centrifuge -

本研究的目的是阐明在离心力场中去除硬表面上的颗粒固体时机械能的贡献。通过控制板/固体界面的离心力的角度，所施加的力在强度和垂直/横向力比上都是可调的。当垂向力分量保持不变时，颗粒去除百分比随着横向力分量的增加而增加。然而，如果在不同的力水平下横向力分量保持不变，颗粒的去除率随着垂直方向力分量的增加而明显降低。这些结果表明，当垂直于基质平面的力作用时，只有水平方向的力才能对颗粒土起到最有效的去除作用。如果垂直面上的力推动颗粒，则颗粒的去除率随着垂直推力的增加而减小。这一基础性和解析性的研究结果似乎有助于清洗剂研究的发展。

The object of this research has been planned to elucidate the contribution of the mechanical energy when particulate solid on a hard surface are removed in a field of centrifugal force.The force to be applied was ebjustable both in intensity and verticcal/holizontal force ratio by controlling the angle of the centrifugal force at the plate/soild interface.When vertical force component is kept constant, % particle removal increases with increasing holizontal force component.If, however, holizontal force component is kept constant at different force levels, % particle removal apparently decreases with increasing vertical( pull the particle against the solid surface) force component.These results tell that only holizontal force plays atmost effective removal of the particulate soil when the force applied parallel to the plane of the substrate.If the vertical force to the plane to push the the particle, then % removal decreases as the vertical push force increases.These fundamental and analytical survey seems helpful for the development of the detergency study.
