Zakusilo R. The regularities of influence of composition and method of obtaining of explosive composition and polymeric carrier on the properties of shock-tube

Thesis is devoted to the solution of actual scientific-economic task of creation of domestic detonating shock-tube for blasting by determination of conformities of depend-ence of detonation behavior of shock-tube on composition, packing factor and size of crystals of detonating composition, amount and adjectives of layers of polymeric composition-carrier. Polymeric carrier composition, crystalline structure and the geometry of the particles of explosive substances fixed at the polymeric carrier where proved to be the basic factors determining operating characteristics of shock-tube. The influence of polymeric material and method of obtaining the polymeric composition on the detonation descriptions of explosive substance is determined and it is proven that for the complete localization of detonation wave in the cavity of the tube of shock-tube it must be three-layered, consist of the system of linear polymers. It is established that the influence of the composition of materials, density and size of the crystals of explosive substance on the sensitivity of shock-tube to the initial impulse and the stability of detonation wave is approximated by parabolic dependences, which provides the possibility of the optimization of the characteristics of shock-tube. It is proven that the realization of the phase transition of octogen beta-modification into the alfa-modification directly in the cavity of polymeric carrier in the process of its extrusion increases the sensitivity of shock-tube to the initial impulse. The new technology of the production of the domestic of shock-tube is created, which allow to increase safety of blasting.
