【摘要】：为了研究彩虹粉引燃危险性,应用固体燃烧速率试验仪初步甄别了彩虹粉传播燃烧能力,发现堆垛状彩虹粉固体火焰传播危险性较低;采用粉尘爆炸筛选装置,判定彩虹粉具有爆炸性;应用最小点火能测定装置测定彩虹粉粉尘云的最小点火能在24~60 m J之间,最优爆炸浓度为1 167 g/m3;应用快速筛选量热仪测试,彩虹粉在227℃开始分解;固体自燃点测试仪显示彩虹粉在250℃附近会发生自燃。向彩虹粉内添加不同比例相近粒径分布的食用盐粉体进行抑爆研究,结果证明食用盐对彩虹粉具有明显的抑爆效果。
[Abstract]:In order to study the ignition hazard of rainbow powder, a solid combustion rate tester was used to screen the propagation and combustion ability of rainbow powder. It was found that the propagation risk of stacking rainbow powder solid flame was lower. A dust explosion screening device was used to determine the explosion of rainbow powder, and the minimum ignition energy of rainbow powder dust cloud was determined by the minimum ignition energy measurement device, the minimum ignition energy was between 24 and 60 MJ, and the optimal explosive concentration was 1 167 g / m3. The results of rapid screening calorimeter showed that the rainbow powder began to decompose at 227 鈩，
