Screening Smoke Performance of Commercially Available Powders I. InfraredScreening by Graphite Flake

摘要

Commercially available graphite powders are evaluated in the U.S. Army EdgewoodResearch, Development and Engineering Center Smoke Chamber. Figures of merit for weight, volume, and cost constrained applications are described to rate the screening ability of these materials in the visible and infrared. Fundamental properties called performance parameters are identified (extinction coefficient, deposition velocity, packing density, and dissemination yield) for measurements so that chamber characterization can be used to predict smoke performance in the battlefield.
