METHOD FOR ASSESSING COMPATIBILITY EXPLOSIVES WITH STRUCTURAL MATERIALS AND DEVICE THEREFOR Russian patent published in 2016 - IPC G01N33/22 G01N21/35 

FIELD: blasting operations.

SUBSTANCE: group of inventions relates to investigation of change of properties of explosive substances (ES) by means of heat agents, as well as laws of processes of thermal decomposition of ES in presence of structural materials. Method of evaluating compatibility of explosives with structural materials, involving bringing in contact of analysed explosive with structural materials and further laboratory analysis of gaseous medium released during reaction of analysed materials, from which is score compatibility, first ground together explosive, for example, heating coil, and structural materials, metals or organic substances, then they are placed into reaction chamber made in form of heating device, heating is switched on alternating isothermal and non-isothermal modes of heating reaction chamber, observation in online mode is carried out by registration of measured parameters of analysed gas medium to produce measurement signal with simultaneous combination of taking into account graphic results of thermal gravimetric differential thermal analysis methods and IR spectrometry method, which is interfaced with system of infrared spectrometer interface and PC software algorithm based charting relationships of measured parameters of gas medium from time of observation, converted from Gram-Schmidt profile in graphical view peaks of infrared spectrum. Invention also covers device for realising said method.

EFFECT: possibility of reliable determination of developing critical conditions of incompatibility of contacting with ES structural material, as well as higher information value of estimation.
