摘要:
基于非储压干粉灭火装置的安全、高效等特点，设计不同氧化剂配比的产气药柱的基本配方，对比不同氧差下药柱的燃速，并对残渣进行XRD试验分析、产气量测试比较。结果表明：氧化剂含量对燃速和产气量影响很大，设计氧差时要考虑氧化剂耗氧量；药柱燃烧后残渣过多会降低性能。为寻求稳定燃速和低残渣，应控制氧差在-15至-20之间为佳。最优基本配方（质量分数）是氧化剂77.2%、可燃剂11.4%、黏结剂11.4%。氧差-15时，燃速达到8.95 g/s，产气量为0.245 L/g；较某消防药柱产气量提升19%。
Abstract:
Based on safety and high efficiency of dry powder fire extinguishing device with non-pressure storage, basic formulas with different oxidizer ratios were designed for the gasproducing grains. Burning rate under different oxygen differences was compared, the residue was analyzed by XRD test, and the gas production was also compared. The results show that oxidant content has a great influence on burning rate and gas production, so oxygen consumption of the oxidant should be considered when oxygen difference is designed. Too much residue after combustion will reduce performances. In order to seek stable burning rate and low residue, the best oxygen difference should be controlled to be around －15 to－20. In the optimal basic formula, mass fractions of oxidizer, combustible agent, and binder are 77.2%, 11.4%, and 11.4%, respectively. When oxygen difference is －15, burning rate is 8.95 g/s, and gas production is 0.245 L/g. Compared to a firefighting grain, the gas production increases by 19%.
