火工药剂感度的一般概念是指药剂在受到外界能量作用时发生激发化学反应的难易程度。外界能量有很多形式:如:机械作用(撞击、摩擦、针刺)、热作用(火焰、加热)、波作用(冲击波、爆轰波)、电作用(电火花、静电)、光作用、粒子作用等,与能量形式相对应,药剂表现出相应的感度。试验表明:外界能量形式不同,引起药剂发生激发化学反应所需能量的大小也不相同,药剂的感度不仅决定于所用材料的化学结构、组成、物理化学性能,还与药剂的物理状态、装药条件有关,感度是大量因数的函数。这涉及到药剂的激发化学反应机理,机理不同,所需E栅(能栅,为表征感度的特征量)的大小也不同。
The general concept of pyrotechnic sensitivity refers to the ease with which the chemistries trigger chemical reactions when subjected to external energy. There are many forms of energy in the outside world: mechanical action (impact, friction, acupuncture), thermal action (flame, heating), wave action (shock wave, detonation wave), electrical action Role, etc., corresponding to the form of energy, the agent showed the corresponding sensitivity. Experiments show that the energy forms of external agents are different due to different external energy forms. The sensitivity of the agents not only depends on the chemical structure, composition, physical and chemical properties of the materials used, but also the physical state of the agents, the charge Conditions, sensitivity is a large number of factors as a function of. This involves the chemical activation mechanism of the agent, the mechanism is different, the required E-grid (energy grid, to characterize the sensitivity of the characteristics of the amount) is also different.
