Each pyrotechnic composition has specific sensitivity such as electrostatic discharge (ESD) sensitivity and friction sensitivity (FS), and it also has specific ignition performance, including luminous intensity (LI) and burning rate (BR). These parameters depend on the concentration of pyrotechnic composition ingredients. In this study, Mg/Ba(NO₃)₂/novolac resin compositions were prepared using different weight ratios (wt.%) of Mg, Ba(NO₃)₂, and novolac resin. Then, they were investigated by their FS, LI, and BR. The results showed that by increasing Ba(NO₃)₂ concentration from 33.76 to 84.54 wt.% Ba(NO₃)₂, the FS increases from 343 N to 65.5 N. However, the LI and BR of this composition increased by increasing Ba(NO₃)₂ concentration until a 3/1 stoichiometric ratio of Mg/Ba(NO₃)₂ (from 13086 to 20588 cd (candela) and 11.25 to 13.71 cm/s, respectively for 33.76 to 64.92 wt.% Ba(NO₃)₂) and decreased afterward (from 20488 to 53.24 cd and 13.71 to 6.45 cm/s, respectively). For Mg/Ba(NO₃)₂/novolac resin containing 3 to 12 wt.% novolac resin FS increased from 56 to above 360 N. LI and BR decreased from 20057 to 1203 cd and 17.3 to 1.2 cm/s, respectively. The stoichiometric ratio of Mg/Ba(NO₃)₂ has the highest enthalpy of reaction. Therefore, it can be concluded that it has the highest LI and BR.

成分比对Mg/Ba(NO3)2/酚醛树脂烟火组合物摩擦敏感性和燃烧性能的影响

每种烟火成分都具有特定的敏感性，例如静电放电（ESD）敏感性和摩擦敏感性（FS），还具有特定的点火性能，包括发光强度（LI）和燃烧速率（BR）。这些参数取决于烟火组合物成分的浓度。在本研究中，使用不同重量比（重量百分比）的Mg、Ba(NO ₃ ) ₂和酚醛清漆树脂制备了Mg/Ba(NO ₃ ) _{2 /酚醛清漆树脂组合物。}然后，他们被他们的 FS、LI 和 BR 调查。结果表明，通过将 Ba(NO ₃ ) ₂浓度从 33.76 提高到 84.54 wt.% Ba(NO ₃ ) ₂，FS 从 343 N 增加到 65.5 N。但是，该组合物的 LI 和 BR 通过增加 Ba(NO ₃ ) _{2浓度直到 Mg/Ba(NO 3} ) ₂的 3/1 化学计量比（从 13086 到20588 cd（坎德拉）和 11.25 至 13.71 cm/s，分别为 33.76 至 64.92 wt.% Ba(NO ₃ ) ₂）并随后下降（分别从 20488 至 53.24 cd 和 13.71 至 6.45 cm/s）。对于含有 3 至 12 wt.% 酚醛树脂的 Mg/Ba(NO ₃ ) ₂ /酚醛清漆树脂，FS 从 56 增加到 360 N 以上。LI 和 BR 从 20057 年分别降低到 1203 cd 和 17.3 到 1.2 cm/s。_{Mg/Ba(NO 3} ) ₂的化学计量比具有最高的反应焓。因此，可以得出结论，它具有最高的 LI 和 BR。
