摘要：

The forces of interaction between hydrophilic disperse particles in a humidified dispersion have been analyzed. The minimum volume fraction of water, which is acceptable for the application of DLVO theory formulas in computing the interaction between particles, was determined. It is shown that the formation of thin restricted water layers in gaps between hydrophilic particles gives rise to conditions for the attraction of the latter stipulated by the capillary forces that significantly change the properties of dispersions.
