Explore The Technical Means Of Red Phosphorus Smoke Attenuation Of Infrared Radiation

Started from obscuring mechanism of phosphorous smoke and thermodynamics property of compositions of red phosphorus smoke-producing mixtures, calculation of therrnodynamic parameter is programed, and formulas of red phosphorus smoke-producing mixtures is based on the results of calculation in this text. Reaction mechanism of the mixtures is tried to change by entering metal powder and metal oxides, organic matter that contains much carbon and special binders into the mixtures in order to produce more substances of infrared extinction and arrive at the aim of infrared extinction.Results of experiments have testified that smoke generated by some formulas has improved the effect of extinction in infrared waves. The reasons of the extinction are analysed by compositive experiments of typical formulas. Basic compositions of anti-infrared red phosphorus smoke-producing mixtures are fixed. Furthermore, the relation between mass of smoke-producing mixtures as well as relative humidity and infrared transmittance is analysed, and the influence between special binder and compatibility and stability of the mixtures is also studied and analysed in this text.
