摘要:为避免传统的红光烟火药形成致癌多氯芳香化合物的可能，以及减少Sr盐带来的潜在危害，研究了Sr盐对Li盐光谱的影响，设计不同含量Sr盐的无氯红光烟火药配方，并进行了性能测试。结果表明：10%Sr盐含量的烟火药即具备高亮度和高色纯度，该配方不含氯，以SrOH和Li为红光发射源，符合绿色烟火药的发展趋势。
Abstract:To avoid the possibility of forming carcinogenic polychlorinated aromatic compounds of traditional red flare pyrotechnic composition, and reduce the potential hazards associated with strontium salts, the effect of strontium salts on lithium salt spectra was investigated, a chlorine-free red flare pyrotechnic composition formulas with different strontium content was designed, and the properties were tested. The test results show that the formula containing 10% strontium salt possesses high brightness and high color purity. The formula doesn’t contain chlorine, and adopts SrOH and Li as red light emission source, which is corresponding to the development tendency of green pyrotechnic composition.
