Carbon-rich Combustion Type Fast Fat Smoke Suppressant Formulation Design And Performance

In this dissertation, the mechanism figure of soot formation, the extinction theory and the testing technology of hydrocarbon pyrotechnic fast smoke agent are expounded. The paper is directed at how to enhance the infrared extinction ability and the burning speed of the burning fast smoke agent. The main components of the smoke are congeries of carbon. After the theoretical analysis and the experimental contrast confirmation, the series essential composition has designed. The mostly material of smoke agent are fluorene, the chlorinated paraffin wax is as subordination material of smoke agent, and the combustible material of smoke agent is the magnesium. The result showed, in the smoke agent, that the oxometallate and the fluoride was superior to the metal oxide and nanometer material oxidant. Some additive substance as graphite, cesium compound and the hot balance confrontation improvement smoke agent becomes the smoke performance to have well affects. The influence of the material granularity , the charge density, the atmospheric relative humidity, combustion condition has be tested and analyzed.Optimal smoke composition, which is designed by the test experiment in smoke-box experimentation. The burning speed of the medicament is top 1g/s. The percent of the IR pass through the smoke screen is only 40%. The Rich-carbon burning fast smoke agent has carried on the performance test to the essential formula.
