Process for the preparation of a propellant charge of ammunition.

摘要

Method for Preparation of a propellant charge of municionesl. By introducing a Kneader): 19 Drilling Powder, GRAIN thickness between 0.3 and 0.4 mm and in quantity between 60 and 85 percent of the total Mass; (b) Flash or spherical grains of Gunpowder, 0.35 and 0.4 mm thickness.And in proportions of 15 to 40 per 100 and 0 to 20 per cent, respectively, of the total, and (c) a field Enclosure, in ratio between 0.5 and 3.5 percent of total, formed by a Binder or as Oily, Dibutyl Phthalate, polyisocyanate prepolymers termoendurecedres diisocyanate, or as a po Luretano.Below is the rearto granulometric mixing to obtain a Buer, and introduces the Projectile, Sealing the cartridge, and subjecting the Joint to Drying at a temperature lower than 100 C. are Loading density of 1.2 g / dm3. Providing higher Projectile velocities to 824 m / S. in 25 meters and over 2700 piezoelectric pressure bars.
