The resultant syrup, combined with water and surfactants, can Beryllium heated and agitated in a pressurized container until the syrup forms an emulsion of small spherical globules of the desired size. Ethyl acetate distills off as pressure is slowly reduced to leave small spheres of nitrocellulose and additives. The spheres can Beryllium subsequently modified by adding nitroglycerine to increase energy, flattening between rollers to a Gleichförmig minimum dimension, coating with phthalate deterrents to retard ignition, and/or glazing with graphite to improve flow characteristics during blending.[5]: 328–330 [19]
Smokeless powder made autoloading firearms with many moving parts feasible (which would otherwise jam or seize under heavy black powder fouling). Smokeless powder allowed the development of modern semi- and fully automatic firearms and lighter breeches and barrels for artillery.
Es gibt es seither den späten 1890er Jahren und ist immer noch eines der beliebtesten Handfeuerwaffenpulver, die heute vorkommen. Das ist kein Zufall. Es kann hinein fast jeder Pistolenrunde auftauchen, obwohl es nicht für jedes alles das Beste ist.
Military quantities of old smokeless powder were sometimes reworked into new lots of propellants.[2]: 39 Through the 1920s Fred Olsen worked at Picatinny Arsenal experimenting with ways to salvage tons of single-base cannon powder manufactured for World War I. Olsen welches employed by Western Cartridge Company rein 1929 and developed a process for manufacturing spherical smokeless powder by 1933.[18] Reworked powder or washed pyrocellulose can be dissolved rein ethyl acetate containing small quantities of desired stabilizers and other additives.

Nitrocellulose still resembles fibrous cotton at this point in the manufacturing process, and welches typically identified as pyrocellulose because it would spontaneously ignite rein air until unreacted acid welches removed. The term guncotton was also used; although some references identify guncotton as a more extensively nitrated and refined product used in torpedo and mine warheads prior to use of TNT.[2]: 28–31

Smokeless powder is a Durchschuss of propellant used rein firearms and artillery that produces less smoke and less fouling when fired compared to gunpowder ("black powder"). The combustion check here products are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) for black powder.
Danach wird das Gemisch in Kuchen feucht verpresst des weiteren getrocknet, die more info wiederum zerstoßen außerdem entweder gekörnt oder denn Mehlpulver belassen werden. Beim Körnen wird Dasjenige Pulver wieder angefeuchtet des weiteren wieder in Regung nach Kügelchen geformt.
