Explosion Phenomena and Key Factors of Liquid Explosive Materials

1 Explosion Phenomena and Key Factors of Liquid Explosive Materials 

Explosions from liquefied gas pipes, gasoline tanks, chemical processes of industry, gas inside mines, coal dust, and all explosive materials are chemical explosions. The explosion caused by mixtures of inflammable liquid leakage and air is also chemical one. All staffs, which can have chemical explosions, are named explosives. If the used staff is in liquid or sol-gel, this is the explosion from liquid explosive materials. This chapter studies the explosion variation law and features of liquid explosive materials. 

The explosive abilities are determined by the exothermicity, rapidity, and gas production of explosion reaction. 

1 Heat/Energy Releasing of Liquid Explosive Explosion 

All explosion reactions are exothermic with the formation of new molecules. Considering the decomposition of a compound, certain amount of energy must be supplied to activate the molecules or break the chemical bonds, which subsequenfly generate new compound and release heat. If the released heat cannot activate the subsequent reactions, the chemical reactions will terminate automatically. To maintain such a reaction, energy has to be supplied from the environment. Obviously, these materials are not explosives. If the energy released from the initial explosive reaction activates the unreacted molecules, and the explosive reaction propagates continually until all reactants are consumed.
