项目摘要

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.

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/固体界面处的离心力的角度，可以调节所施加的力的强度和垂直/水平力比。当垂直分力保持恒定时，颗粒去除百分比随着水平力的增加而增加然而，如果水平分力在不同的力水平下保持恒定，则随着垂直力（将颗粒拉向固体表面）分力的增加，颗粒去除率明显降低。这些结果表明，当力平行于基材平面施加时，只有水平力才能最有效地去除颗粒土壤。如果垂直力作用于平面以推动颗粒，则去除率随着垂直推力而降低。这些基础和分析调查似乎有助于去污力研究的发展。
