Title Research of smokeless safety ignition composition and applied in the ignition wire
Abstract
The smokeless safety ignition composition is designed by use guanidine nitrate and barium nitrate complexes as oxidizer,boron powder as combustibles,iron(III) oxide as addenda which is used to increase the combustion speed.Using the thermal analysis equipment to determine iron(III) oxide as accelerators. Research on the combustion performance , smoke and sensitivity density through the experiment of burning rate,the concentration of smoke and the experiment of sensitivity .Then prepared the formula into ignition wire to test.The results show that: when guanidine nitrate/barium nitrate/boron = 55/30/15 and add 3% iron(III) oxide extra,the combustion speed of the line 0.95 cm/s, the ratio of black powder which produces smoke reduction of 72.1%,sensitivity lower than black powder.
Keywords ignition composition smokeless thermal analysis sensitivity guanidine nitrate
