FIELD: closed volumes fire extinguishing chemical mean generating inert gasses; mean is used for fire extinguishing in different branches of national economy, in which usage of traditional means is not allowed or ineffective, for example, especially pure chemical and other productions, accumulating batteries compartments of ships, separate joints of aeroplanes, computer units. SUBSTANCE: closed volumes fire extinguishing chemical means diluting fire atmosphere with inert gas are made in the form of ammonium azide tablets pressed to density of 1.31 - 1.32 g/cu-cm and covered by protective film of polymeric lacquer. High density of proposed mean allows to produce record volumetric concentration of nitrogen per initial substance weight and volume unit, products of proposed mean burning are ecologically pure. EFFECT: chemical mean allows to produce record volumetric concentration of nitrogen per unit of initial substance weight and volume, products of its burning are ecologically pure. |
