Apstrakt

U skladu sa trendovima demilitarizacije zastarelog naoružanja i municije, koja predstavlјa teret za svaku vojsku i svaku državu, došlo je do svetskog razvoja tehnologije recikliranja koja omogućava ponovno korišćenje različitih eksploziva, kao i smanjenje potreba za opasanim sintezama ovih supstanci. Odlaganje neperspektivne municije i uništavanje bojevih glava, koje sadrže eksploziv, na otvorenom terenu često može biti skupo i ekološki neprihvatljivo rešenje, što uzrokuje kontaminaciju zemlјišta, vazduha i vode.  U ovom radu ispitane su karakteristike recikliranog trinitrotoluena TNT (r-TNT) u odnosu na čist TNT. TNT dobijen prilikom demilitarizacije starih bojevih glava i toplјenjem različitih sastava eksplozivnih punjenja koja sadrže TNT, testiran je u formi livenih i presovanih punjenja - eksperimentalnih uzoraka. Ispitana je mogućnost obrade tehnologijom livenja i presovanja kako bi se procenila mogućnost praktične primene ovog recikliranog eksploziva. Određena je brzina detonacije i ispitane su fizičke i hemijske osobine r-TNT. Osetlјivosti r-TNT i čistog TNT su upoređene. Preostale nečistoće u recikliranom eksplozivu su ispitane infracrvenom spektroskopijom sa Furijeovom transformacijom (FTIR)  i diferencijalnom skenirajućom kalorimetrijom (DSC), i urađen je test vakuum-stabilnosti. Ispitani r-TNT je pokazao veoma dobre rezultate u svim testovima i može se koristiti u različitim eksplozivnim punjenjima i za različite primene.
