Abstract

1. Способ оценки совместимости взрывчатых веществ с конструкционными материалами, включающий приведение в контакт исследуемого взрывчатого вещества с конструкционными материалами и последующий лабораторный анализ параметров газообразной среды, выделяющейся при взаимодействии анализируемых материалов, на основании которого делается оценка совместимости, отличающийся тем, что сначала измельчают совместно взрывчатые, например, тэн, и конструкционные материалы, металлы или органические вещества, затем помещают их в реакционную камеру, выполненную совмещенной с термонагревательным устройством, включают нагрев, используя неизотермический режим нагрева реакционной камеры, наблюдения в режиме онлайн ведут путем регистрации измеряемых параметров анализируемой газовой среды с получением измерительного сигнала, с одновременным сочетанием учета графических результатов термогравиметрического, дифференциально-термического методов анализа и метода ИК-спектрометрии, которые системой сопряженного с ИК-спектрометром интерфейса и программного обеспечения персонального компьютера (ПК), основанного на алгоритме построения графиков зависимостей измеряемых параметров газовой среды от времени наблюдения, преобразованы из Грам-Шмидт профиля в графический вид системы пиков ИК-спектра, а оценка совместимости (ВВ) с конструкционными материалами формируется поэтапно, на соответствие критериям совместимости, сначала по виду и времени появления и/или исчезновения продуктов взаимодействия исследуемых материалов, по изменению термических характеристик ВВ.2. Способ по п. 1, отличающийся тем, что анализ совместимости ВВ и к1. A method for evaluating the compatibility of explosives with structural materials, including contacting the test explosive with structural materials and subsequent laboratory analysis of the parameters of the gaseous medium released during the interaction of the analyzed materials, based on which a compatibility assessment is made, characterized in that the explosives are co-milled first , for example, ten, and structural materials, metals or organic substances, then place them in the reaction chamber carried out combined with a thermo-heating device, include heating using a non-isothermal heating mode of the reaction chamber, online observations are made by recording the measured parameters of the analyzed gas medium to obtain a measuring signal, while simultaneously taking into account the graphical results of the thermogravimetric, differential-thermal analysis methods and the IR method -spectrometry, which is a system associated with an infrared spectrometer interface and personal software A computer (PC) based on an algorithm for constructing graphs of the dependences of the measured parameters of the gaseous medium on the observation time is converted from the Gram-Schmidt profile to the graphical form of the IR spectrum peak system, and the compatibility assessment (BB) with structural materials is formed in stages, according to the compatibility criteria , first, by the type and time of appearance and / or disappearance of the interaction products of the studied materials, by the change in the thermal characteristics of explosives. 2.
