At 13:15 on May 13, Luxi County aluminum powder plant aluminum powder workshop spray powder storage library, an explosion occurred, before and after the Treasury, the right three sides of the brick wall and the top of cement prefabricated panels were destroyed, the furnace on duty 5 employees were killed, 3 were seriously injured, the economic loss of 300000 yuan.According to the authoritative exploration, analysis, this explosion was caused by spontaneous combustion of aluminum silver, the same day, due to heavy rains, heavy air humidity, aluminum powder Chemical reaction with humid air (with a small amount of water) generates oxygen and releases a large amount of heat which ignites spontaneously at a localized temperature, causing the aluminum powder in the air, which reaches the explosion limit, to explode.
