The new instruments of mass destruction — nanopyl

New weapons of mass destruction - nanopylLater in the armies of the world may seem nanopyl, are small particles that can cause destruction to the tremendous distance from the epicenter. South American scientists have found that the dust, which appears at industrial scale processing of various nanomaterials, has the highest probability of an explosion. For this to happen, enough sparks just 1/30 of that required to ignite the sweet dust.

Scientists conducted a study of 3 types of so-called "non-conventional dust": nanofoam, flocculants, which are produced in the manufacture of floor coverings, and hybrid consistency of flammable gases and dust. As a result, it was found that nanopyl, the size of which is less than the flour or starch, can catch fire from the smallest spark. Scientists have warned producers about the need to strengthen safety measures at industrial facilities.

In order to blow up the iron nanomaterials, for example, duralumin dust, need only 1 mJ of energy, which equals 1/60 of the amount of energy that is needed to ignite the dust from wheat. A flocculating ability Key generating static electricity, which may lead to accidental exposure. Ignite combustible materials can cause great destruction and danger to life at great distances from the epicenter of the explosion.

Dust can become deadly material at sites with a closed place — elevators, mines, various chemical plants. Excellent investigated only explosive characteristics of common dust, and the materials of the future may bring even more severe threat.

First fixed explosion flour dust happened back in 1785 in Turin. Then, trying to kill a fly, a local baker case undermined the entire economy. As a result, the explosion killed several people. After that similar cases are recorded frequently. In 2008, the state of Georgia in the United States occurred explosion sweet dust in a factory. As a result, the incident affected 13 people.

Dust — it's a hard substance with a diameter of less than 420 microns. At the current time, explosive characteristics nanofoam studied quite poorly. Similarly, it is clear that the greater the relative density of the material surface has, the stronger explosion. Apart from this, the microparticles can make ensemble — nanopowder which ignites at 1 mJ of energy.
