Abstract
Przedmiotem wynalazku jest trójbazowa, bezdymna mieszanina prochowa zawierająca trzy podstawowe składniki energetyczne i strukturalne w postaci nitroestrów: nitrocelulozy, nitrogliceryny i diazotanu glikolu dietylenowego (dinitrodwuglikolu) a także ftalan dietylu spełniający rolę plastyfikatora, stabilizator stałości chemicznej – N,N'-dietylo, N',N'-difenylomocznik (Centralit-I) oraz dodatki technologiczne - wazelinę i grafit, ułatwiające formowanie mieszaniny prochowej w celu otrzymania ziarna prochowego o odpowiednim kształcie i wymiarach. Tego rodzaju masy prochowe charakteryzują się stosunkowo niską kalorycznością, zazwyczaj bliską wartości 4600 J/g, co powoduje, że są przydatne do wytwarzania bezdymnych prochów artyleryjskich o niskiej erozyjności. Z kolei niska erozyjność prochów przyczynia się do wydłużenia żywotności luf dział artyleryjskich. Istota trójbazowej masy prochowej według wynalazku, zawierającej: nitrocelulozę, nitroglicerynę, diazotan glikolu dietylenowego, stabilizator stałości chemicznej – N,N'-dietylo, N',N'-difenylomocznik oraz wazelinę i grafit polega na tym, że mieszanina prochowa składa z 50,0-52,1 części wagowych nitrocelulozy o zawartości azotu stanowiącego 13,28% jej masy, 31,0-32,1 części wagowych nitrogliceryny, 12-13 części wagowych diazotanu glikolu dietylenowego, 2,5-3,0 części wagowych Centralitu-1, 0,8-1,0 części wagowych wazeliny, 0,8-1,0 części wagowych ftalanu dietylu i 0,08-0,1 części wagowych grafitu. Z mieszaniny prochowej według wynalazku można otrzymać drobnoziarnisty bezdymny proch o kaloryczności bliskiej 4600 J/g oraz parametrach balistycznych, zapewniających odpowiednią prędkość wylotową pocisku miotanego w wyniku spalania ładunku prochowego.The subject of the invention is a three-base, smokeless powder mixture containing three basic energy and structural components in the form of nitroesters: nitrocellulose, nitroglycerin and diethylene glycol dinitrate (dinithrodiglycol) as well as diethyl phthalate acting as a plasticizer, stabilizer of chemical stability - N, N'-diethyl, N ' , N'-diphenylurea (Centralit-I) and technological additives - petroleum jelly and graphite, facilitating the formation of a powder mixture in order to obtain a powder grain of the appropriate shape and dimensions. Such powder masses are characterized by relatively low calorific value, usually close to 4600 J / g, which makes them suitable for the production of smokeless artillery powders with low erosivity. On the other hand, the low erosion of gunpowder contributes to the extension of the service life of artillery gun barrels. The essence of the three-base powder mass according to the invention, containing: nitrocellulose, nitroglycerin, diethylene glycol dinitrate, chemical stability stabilizer - N, N'-diethyl, N ', N'-diphenylurea as well as petroleum jelly and graphite consists in the fact that the powder mixture consists of 50, 0-52.1 parts by weight of nitrocellulose with a nitrogen content of 13.28% of its weight, 31.0-32.1 parts by weight of nitroglycerin, 12-13 parts by weight of diethylene glycol dinitrate, 2.5-3.0 parts by weight of Centralit 1, 0.8-1.0 parts by weight of petroleum jelly, 0.8-1.0 parts by weight of diethyl phthalate and 0.08-0.1 parts by weight of graphite. From the powder mixture according to the invention, it is possible to obtain fine-grained, smokeless powder with a calorific value close to 4600 J / g and ballistic parameters ensuring an appropriate muzzle velocity of a thrown projectile as a result of combustion of a powder charge.
