Title Design of the Safety And Environmental Color Smoke
Abstract
The new type of color smoke agent is designed to solve the problems existing in traditional formula from two aspects, in terms of safety, with the modified barium nitrate instead of potassium chlorate as oxidant, which can not only overcome safety problems caused by the high activity of potassium chlorate, and solved the defect of pure barium nitrate which cannot easily ignited and greatly improved the safety reliability; from the aspects of environmental protection, the use of environmentally dyes, avoid the toxic and harmful substances, reduce the pollution of the environment. In this experiment, first, design the modified barium nitrate with different combustion reaction formula through theoretical calculation, and the formula are positive oxygen balance, zero oxygen balance and negative oxygen balance. Then select the ones with good smoke effect , compared with the formula which used high potassium chlorate as an oxidant. The formula with modified barium nitrate as oxidant are low sensitivity, good stability, but are not easy to ignite, and formula with potassium perchlorate as the oxidant are easily ignited, but the sensitivity is high.So the final design of the formula with two kinds of oxidizer,compared the different proportion of content formula,and select the best formula which can easily ignited and the sensitivity is low, smoke effect is good.
