Measurement of the Adhesive Force between Particles of Powdered Materials and a Glass Substrate by Means of the Impact Separation Method. III. : Effect of Particle Shape and Surface Asperity
スポンサーリンク
概要
- 論文の詳細を見る
The effect of particle shape and surface asperity on the adhesive force between particles of powdered materials and a glass plate was investigated by the impact separation method. It was found that the adhesive force between particles and the glass plate generally increased as the particle shape approaches a sphere and there is a linear relationship between the logarithm of adhesive force and shape index, regardless of the material. This result may be related to the effective area of contact and the contacting state between particles and the substrate. The presence of protuberances or fine particles on the surface reduced the adhesive force between particles and the plate. The mechanism is discussed on the assumption that the adhesive force is solely due to the van der Waals force.
