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作用下去除坚硬表面上的固体颗粒时机械能的贡献。通过控制离心力在板/固界面处的角度，施加的力在强度和垂直/水平力比上都是可调节的。当垂直力分量一定时，颗粒去除率随水平力分量的增大而增大。然而，如果在不同的力水平下保持水平力分量不变，则随着垂直力分量（将颗粒拉向固体表面）的增加，颗粒去除率明显降低。这些结果表明，只有水平力在平行于基材平面时才能最有效地去除颗粒土。如果垂直力向平面推动颗粒，则随垂直力的增加%的去除量减小。这些基础性和分析性的调查似乎有助于洗涤剂研究的发展。

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.
