METHOD OF MOISTURE REMOVAL FROM PYRO POWDERS |
摘要 |
FIELD: weapons and ammunition.SUBSTANCE: proposed method comprises two-step removal of moisture brought about by wetting from powder elements. First, moisture is displaced from powder elements by ethyl alcohol in concentration of 95-96% under centrifugal force in sprinkling of powder with alcohol in amount of 0.35-0.50 l/kg for fine powders and 0.50-1.00 l/kg for medium powders with simultaneous powder expression for 2-3 min and final expression for at least 10 min. Removal of residual amount of water-alcohol mix from powder to required magnitudes is performed by drying in table drier or dry-cure cabinets by air heated to 25-40°C for at least 1 hour with simultaneous forced discharge of used air or drying in 70 mmHg-vacuum for at least 1.5 h. Batch centrifuges are used for displacement.EFFECT: fast and safe process, higher efficiency.3 cl, 2 tbl |
