A progressive halogen‐free multicolored smoke system to obtain white, red, violet, yellow, green, and blue smoke color is presented. The nitrogen‐rich salt guanidinium 5,5′‐azotetrazolate (GZT), which is usually applied as a gas generator or propellant ingredient, was combined with different smoke dyes (Solvent Red 1, Solvent Violet 47, Solvent Green 3, Solvent Yellow 33). These two‐component smoke mixtures offer a convenient and safe multicolor approach without the need for potassium chlorate or any other hazardous material. The common smoke characteristics with respect to burn time/burn rate, yield factor, transfer rate, as well as energetic properties were determined and compared with classic chlorate‐based formulations currently used. To the best of our knowledge, nothing comparable is known in the literature and a completely new research area in modern pyrotechnics is opened.

胍基5,5'-偶氮四唑酸盐:用于无卤烟雾信号的彩色变色龙。

提出了一种渐进的无卤素彩色烟雾系统,以获得白色,红色,紫色,黄色,绿色和蓝色的烟雾颜色。富含氮的5,5'-偶氮四唑鎓胍盐(GZT)通常用作气体发生器或推进剂成分,并与不同的烟雾染料(溶剂红1,溶剂紫47,溶剂绿3,溶剂黄33)结合使用)。这两种成分的烟气混合物提供了一种方便,安全的多色方法,而无需氯酸钾或任何其他有害物质。确定了有关燃烧时间/燃烧率,产率,传输率以及能量特性的常见烟雾特性,并将其与当前使用的基于氯酸盐的经典配方进行了比较。据我们所知,
