摘要本文对CuO在高温下进行灼烧预处理,进而研究预处理的氧化铜反应活性的变化以及对GN/CuO、ADC/CuO气体发生剂的热性能及点火性能的影响。X射线衍射实验结果表明:经过350℃、450℃、600℃灼烧处理后的CuO未发生晶型转变,但晶形变完整,结晶度变好,晶粒尺寸在经600℃灼烧后增大,表面活性降低。TG-DSC联用热分析测试结果表明:经灼烧处理的CuO提高了GN/CuO和ADC/CuO混合物的热分解稳定性和分解速率。点火实验结果表明:未经灼烧和经350℃、450℃灼烧的CuO与GN或ADC的混合物均能被点燃,而经600℃灼烧处理的混合物不能被点燃。综合来看,不同灼烧温度预处理的CuO反应活性不同,从而对GN/CuO和ADC/CuO混合物的热性能及点火性能有不同的影响。25365

Title Study on the reactivity of copper oxide
Abstract
In this paper,the copper oxide (CuO) is beneficiated by calcining at high temperatue.Then,the thermal and ignitability experiments are carried on to study the change of the reactivity of CuO and the effects of CuO pretreatment on the characteristics of GN/CuO and ADC/CuO.The X-ray diffraction experiments results indicate that the crystal transition does not occur after the CuO pertreatment,but the crystallinity becomes better and the crystal grain size increases after calcining at 600℃ with the surfactivity decreasing .The thermal analysis testing results on GN/CuO and ADC/CuO show that the heat decomposition stability of GN/CuO and ADC/CuO is improved with the burned CuO.At the same time,the gas producing rate also increases.Ignition experiment results also illustrate that mixtures consisting of the CuO which are not calcined and are calcined at 350℃,450℃ as oxidant all can be ignited.However,the mixtures containing the CuO calcined in 600℃ are not ignited. In general, the different calcinate temperature on CuO has different influence on the reactivity of CuO and the thermal and ignition performance of GN/CuO and ADC/CuO.
