The effects of the content , granularity and purity of the raw materials ( zirconium powder , viton and dicyandiamide ) on the combustion rate were measured and their effects on its detonation heat and its combustion heat were estimated . the investigation on the combustion reaction mechanism showed that surface decomposition of dicyandiamide was the control step of the combustion reaction . the slowdown and combustion - resistant effects of dicyandiamide were of endothermic characteristic 测量了锆粉、氟橡胶、双氰胺等原材料含量、粒度、纯度等对药剂燃速的影响，估算了它们对药剂爆热和燃烧热的影响，并对药剂燃烧反应机理进行了探索研究，发现双氰胺的表面分解是药剂燃烧反应的控制步骤，其减速、阻燃作用具有吸热特征，氟橡胶对药剂的热输出有较大贡献。
Theoretical analysis and testing results demonstrated that viton , a new substitute of the former plasticizer , could noticeably improve its performances , which has been proved as the important improvements of the mixture . due to the favorable thermochemistry performance , dicyandiamide can act as a good combustion - rate regulator . the addition of antistatic agent can desirably increase the antistatic capability of the mixture , and the testing results showed that the performance of the improved mixture was excellent 理论分析和测试结果均表明了以氟橡胶取代耐水点火药中原粘合剂将使药剂的各项性能有明显的改善，是耐水点火药改进的重要方面；双氰胺具有良好的热化学特性，作为耐水点火药改进中的燃烧速度调节剂具有很好的调速效果；抗静电剂的加入，进一步提高了药剂的抗静电能力，测试分析表明改进后药剂的性能更加优异。
Authogonal experiment is designed by combining adding additive , increasing the autumn temperature and decreasing the proportion of urotropine and nitric acid . the better conditions of technology are : the mount of dicyandiamide is 0 . 8 % of the mount of urotropine , the autumn temperature is 30 , the proportion of urotropine and nitric acid is 1 : 1 1 ; the mount of urea nitrate is 0 . 9 % of the mount of urotropine , the autumn temperature is 30 , the proportion of urotropine and nitric acid is 1 " . 11 本研究综合添加剂的加入量、提高成熟期温度和降低乌洛托品与硝酸的投料比进行了正交实验研究，确定其较佳工艺条件为：双氰胺的加入量为乌洛托品加入量的0 . 8 ，成熟期温度30 ，乌洛托品与硝酸的投料比1 ： 11 ；硝酸脲的加入量为乌洛托品加入量的0 . 9 ，成熟期温度30 ，乌洛托品与硝酸的投料比1 ： 11 。
