Description
Technical Field
The invention relates to an oxygen-containing non-toxic high-energy cloud blasting agent, and belongs to the technical field of cloud blasting agents.
Background
The cloud bomb is also called a fuel air bomb (FAE for short), and is a warhead part which is actually composed of a container filled with fuel (mostly liquid, gas and solid high-volatility combustible fuel such as ethylene oxide, propylene oxide, nitromethane, ethylene acetylene and the like) and a timing initiation device, and the solid-liquid mixed combustible fuel is cloud explosive. The action principle and the process of the cloud blasting bomb are as follows: when the warhead is at a certain height from the ground, the first detonation is carried out, so that the missile-borne chemical fuel is dispersed in the air, fine fog particles formed by dispersed fuel are quickly mixed with the surrounding air to form a combustible aerosol cloud (namely fuel air explosive) with a certain diameter and thickness, and then the missile-borne detonation detonator ignites the cloud to excite the detonation, thereby achieving the effect of destroying and killing the target.
The cloud detonation bomb has great destructive power, and is mainly embodied in three aspects of more released energy, long detonation action time and large sweep range. The cloud explosive is not a common explosive but a flammable chemical substance, and a large amount of oxygen in the air around an explosion point is fully utilized during explosion. The combustible fuel in the self component of the cloud explosion agent has high combustion speed if containing oxygen element, and the oxygen element contained in the oxygen-containing fuel has self oxygen supply capacity during combustion, so that the fuel can be combusted more fully, and the energy is released more completely. The polyether oxygenated fuel has self oxygen supply capacity, is fully combusted, reduces harmful emissions during combustion, and is a clean energy with great development prospect. Compared with the traditional cloud explosion agent, if the polyether oxygenated fuel is added into the cloud explosion agent as an additive, a higher cloud diffusion diameter can be obtained, and the secondary explosion accelerates the propagation speed of the fireball by matching with the micromolecular fuel with a lower flash point, so that the detonation is easier to achieve, the energy release is more complete, and the environment is protected and no pollution is caused in the using process.
