Study on anti-infrared performance of organohalogen polymer smoke agent

Abstract Presented herein is an experimental study on the organohalogen polymer smoke agent. In box experiment, transmittance of agent at 3-5 μm and 8-14 was used as index, effects each factor anti-infrared performance were analyzed by orthogonal test method. The results showed that main factors affecting extinction properties in infrared band zinc magnesium mass ratios Zn-Mg alloy powders, Particle size types polymer, secondary ratio. best composed 30% Zn-10%Mg powder (>325mesh), 50% CP-70, 20% KClO 4 to 3-5μm 8-14μm bands 27.67% 58.07%, respectively, corresponding TOP 93.82 m 2 ·kg 1 39.69 . combustion Zn compared experiment. instead has a faster burning speed, larger flame area, higher temperature.
