Basic Research on Powder Adhesion

Abstract

Regarding the relationship between powder adhesion and flow velocity, when the flow velocity is low, low-speed adhesion occurs due to the small force to peel off the adhesion, and when the flow velocity is high, high-speed adhesion occurs due to the large adhesion force such as electrostatic force.

In this report, we examined the effect on the relationship between powder adhesion and flow velocity when the physical properties of the powder change, using fine powder on the order of several μm to nm, for which needs have been increasing in recent years. In addition, I examined by experiments how much the flow velocity was specifically appropriate for each powder.
