Abstract
Способ получения сферического пороха для дробовых патронов к гладкоствольному спортивно-охотничьему оружию 12, 16 и 20 калибров, включающий загрузку в реактор в водную среду нитроцеллюлозы, графита или технического углерода, приготовление порохового лака в водной среде, диспергирование на сферические частицы, обезвоживание пороховых частиц сернокислым натрием и удаление этилацетата, отличающийся тем, что первоначально в 10 мас.ч. воды готовят суспензию катализаторов горения, состоящих, по отношению к массе НЦ из 1,2…1,8 мас.% свинец (II) - медь (II) фталат оксида, 0,3…0,5 мас.% технического углерода (сажа) и 0,1…0,3 мас.% графита, после чего в реактор заливают 4…6 мас. ч. воды и при выключенной мешалке загружают 1 мас. ч. нитроцеллюлозы с содержанием оксида азота 212…214 мл NO/г или нитроцеллюлозы с 10…30 мас.% возвратных отходов от предшествующих операций и заливают суспензию катализаторов горения в течение 5…10 мин при температуре в реакторе 50°С, затем при температуре 50…60°С заливают этилацетат, загружают к массе пороха 0,1…0,3 мас.% дифениламина, готовят пороховой лак в течение 20…60 мин при температуре 50…68°С, вводят 0,7…1,2 мас.% мездрового клея по отношению к воде и ведут диспергирование порохового лака на сферические частицы в течение 20…40 мин, при температуре 68°С вводят от 0 до 0,1 мас.% сернокислого натрия и ведут процесс отгонки растворителя при следующих температурных режимах в рубашке реактора: подъем температуры теплоносителя в течение 25…30 мин до 68…78°С, выдержка в течение 30…40 мин при температуре 76…78°С, подъем температуры теплоносителя в течение 15…20 мин до 78…84°С, выдержка в течение 30…40 мин при температуре 82…84°С, подъем температурA method of producing spherical gunpowder for shotgun cartridges for smooth-bore sports and hunting weapons of 12, 16 and 20 calibers, comprising loading nitrocellulose, graphite or carbon black into the reactor in an aqueous medium, preparing powder varnish in an aqueous medium, dispersing onto spherical particles, dehydrating powder particles with sulfate sodium and the removal of ethyl acetate, characterized in that initially in 10 parts by weight water prepare a suspension of combustion catalysts, consisting, in relation to the weight of the SC of 1.2 ... 1.8 wt.% lead (II) - copper (II) phthalate oxide, 0.3 ... 0.5 wt.% carbon black (carbon black ) and 0.1 ... 0.3 wt.% graphite, after which 4 ... 6 wt. including water and with the mixer turned off, load 1 wt. including nitrocellulose with a nitric oxide content of 212 ... 214 ml NO / g or nitrocellulose with 10 ... 30 wt.% return waste from previous operations and pour the suspension of combustion catalysts for 5 ... 10 min at a temperature in the reactor of 50 ° C, then at a temperature 50 ... 60 ° C is poured ethyl acetate, loaded to a mass of gunpowder of 0.1 ... 0.3 wt.% Diphenylamine, a powder varnish is prepared for 20 ... 60 min at a temperature of 50 ... 68 ° C, 0.7 ... 1.2 wt. .% glue glue in relation to water and disperse the powder varnish on spherical particles for 20 ... 40 min, at a temperature of 68 ° C, from 0 to 0.1 wt.% Sodium sulfate is introduced and the solvent is distilled off at the following temperature conditions in the reactor jacket: raising the temperature of the coolant for 25 ... 30 min to 68 ... 78 ° C, holding for 30 ... 40 min at a temperature of 76 ... 78 ° C, raising the temperature of the coolant for 15 ... 20 min to 78 ... 84 ° C, holding for 30 ... 40 min at a temperature of 82 ... 84 ° C, raising the temperature
