Przedmiotem niniejszego wynalazku jest sposób zelatynowania nitrocelulozy materjalami dotychczas w tym celu nie sto- sowanemi, wykazuj acemi duze zalety w po¬ równaniu ze stosowanemi dotychczas przy wyrobie prochów nitrowych i celuloidu lot- nemi i nielotnemi substancjami zelatynuj a- cemi.Do tych materjalów nalezy ftalid C6i/4 CO i jego homologi, które, pomi- coy jajac ich nielotnosc, okazuja znaczna wyz¬ szosc nawet wsród najbardziej uzywanych nielotnych materjalów zelatynujacych.Ftalid jest chemicznie bardzo trwaly i uniemozliwia lub utrudnia niebezpieczny rozklad jakiemu ulegaja slabo-dymne pro¬ chy, wskutek czego jest bardzo skutecznym srodkiem ustalajacym, Poza tern odmien¬ nie od licznych srodków zelatynujacych, pochodzacych od mocznika i uretanu, jest on wolny od rozszczepien prowadzacych do polaczen zasadowych (aminów), moga¬ cych ze swej strony powodowac rozklad ni¬ trowanych estrów.Ftalid i jego homologi moga znalezc zastosowanie glównie przy otrzymywaniu prochów nitrocelulozowych z nitroglicery¬ na lub bez, lub celuloidu przez czesciowe lub zupelne zastapienie w omówionych ma- terjalach dotychczas uzywanych srodków zelatynujacych.Szczególnie waznym jest sposób ten dlaprochów nitrocelulozowych z nitroglicery¬ na, poniewaz pozwala zawartosc nitrogli¬ ceryny jeszcze bardziej zmniejszyc bez wystepowania zlych wlasnosci plynnego rozpuszczalnika, podczas gdy plastycznosc prochu na tern nie cierpi, tak, ze mozna je wprost walcowac lub wyciagac, przyczem nadaje sie im duza trwalosc, przez co uzy¬ skuje sie obnizenie ciepla wybuchu, wsku¬ tek czego rura armatnia mniej ulega nagry¬ zaniu.Ftalid moze byc wprowadzony do pro¬ chu przez rozpuszczanie go w nitroglicery¬ nie przesiakajacej nitroceluloze.Nastepujacy sposób mieszania jest jed¬ nym z wielu przykladów otrzymania pro¬ chu armatniego. nitrocelulozy 12 czesci nitrogliceryny 4—6 ,, ftalidu lub jego homologów 1—4 ,, Stosunek uzytych skladników mieszani¬ ny zmienia sie zaleznie od celu uzycia pro¬ chu strzelniczego. PLThe subject of the present invention is a method of gelatinizing nitrocellulose with materials not used for this purpose so far, showing great advantages compared to the volatile and non-volatile substances used so far in the production of nitro powders and celluloid to gelatine acemias. These materials include phthalides. C6i / 4 CO and its homologues, which, apart from their non-volatility, show a significant superiority even among the most used non-volatile gelatinizing materials. Phthalide is chemically very stable and prevents or hinders the dangerous decomposition of weakly smoky gelling materials, as a result of which it is a very effective fixative. Apart from the numerous gelatinizers derived from urea and urethane, it is free from cleavages leading to basic linkages (amines) which, in turn, may cause the decomposition of nitrated esters. Phthalide and its homologues can be used mainly in the preparation of nitrocellulo powders With or without nitroglycerin, or celluloid by partial or complete replacement of previously used gelatinizers in the materials discussed above. liquid solvent, while the plasticity of gunpowder does not suffer, so that they can be simply rolled or pulled, they are given a long durability, which reduces the heat of the explosion, as a result of which the gun tube burns less Phalide can be introduced into the powder by dissolving it in nitroglycerin that permeates the nitrocellulose. The following mixing method is one of many examples of how to obtain cannon powder. nitrocellulose 12 parts nitroglycerin 4-6 "phthalide or its homologues 1-4" The ratio of the mixture components used varies depending on the purpose of the shooting.
