Measurement results of the adhesive force. The ratio of the measurement value of the adhesive force using a Petri dish to the theoretical reference value against the cumulative percentage. Solid, dashed, dotted, and dashed and dotted lines show the 50 μm glass beads, 100 μm glass beads, alumina particles, and silica sand, respectively. a The percentage reflects the number of detached particles/total number of detached particles ratio. b The percentage reflects the number of detached particles/total number of observed particles ratio
