- 摘要:
- 通过对固体惰性介质在减轻镁粉爆炸作用的实验研究，给出影响固体惰化剂作用效果的主要影响因素。实验分别选用3种不同粒径的镁粉样品，并选取氯化钠粉末作为固体惰化介质，用20L球形爆炸测试装置进行实验，测定镁粉中加入不同含量的氯化钠粉末后镁粉爆炸的最大爆炸压力和最大压力上升速率值。结果表明：氯化钠粉末能够起到减轻镁粉爆炸影响的作用，并且随着镁粉粒度的减小，要达到相同的抑爆效果需要的氯化钠粉末的用量将加大。
- Abstract:
- Experiments were made on the effect of solid inert mediums on the magnesium powder explosion pressure and the pressure rise rate. Main fact ors affecting the function of solid inert mediums were given. Three size samples of magnesium powder were selected in experiments, and sodium chloride dust was selected as inert mediums. A 20liter spherical vessel was used to test explosion pressure and the rising rate. By changing concentration of sodium chloride dust inert mediums, the different maximum explosion pressure and the maxi mum rate of pressure rise max were acquired. The experimental results show that sodium chloride dust can be used to reduce the explosion pressure and the pressure rising rate of magnesium powder explosion. Besides, along with the reduction of the particle size of the magnesium powder, more sodium chloride dust is needed to get the same explosion suppression result.
