Relationship between Adhesive Force and Dispersibility of Sub-micron Particles [Translated]†
Adhesive forces of sub-micron particles of limestone were measured by using a split-cell type tensile strength tester under various vapor pressure conditions of water, ethanol and acetone. The adhesive force generated by ethanol vapor or acetone vapor adsorption was smaller than that generated by water vapor adsorption. Agglomerated particles generated from a micro-fluidized bed of the limestone sample with various atmospheric gases were dispersed by a high speed gas stream through a small pipe, and the size distribution of the agglomerates was measured. The agglomerates containing adsorbed ethanol were easily dispersed into the single particles by about half the force required for the agglomerates containing adsorbed water, which qualitatively corresponded to the decrease in the adhesive force of the particles by adsorbing ethanol vapor instead of water vapor.† This report was originally printed in J. Soc. Powder Technology, Japan. 27(3), 159-164 (1990) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of the Soc.
