POWDER DUSTINESS EVALUATION METHOD AND POWDER DUSTINESS EVALUATION DEVICE.

摘要

The purpose of the present invention is to provide a method that enables more precise evaluation of the dustiness of a powder. Provided is a powder dustiness evaluation method in which a powder to be evaluated is dropped onto a liquid contained in a box, which causes the powder to scatter as dust within the box, and the concentration of dust in the air within the box is measured by a dust measuring device. Also provided is a powder dustiness evaluation device comprising a box in which a liquid is contained, and a dust measuring device that measures the concentration of dust in the air within the box when a powder to be evaluated is dropped onto the liquid contained in the box and scatters as dust.
