Abstract:
T hrough theo retical analysis, it w as found that the main facto r to af fect the deposit of aluminum pow der in TN T-RDX-Al casting charge w as the v isco sity o f the charg e. By increasing the v isco sity o f the char ge, the rate of deposit of aluminum pow der can be reduced remarkably and the const itut ions o f the charge can be w ell dist ributed. Experiments demonstr ated that remarkable effect can be achieved by using crushed RDX ( scr eened w ith 180 mesh screen) in cast ing char ge of T NT -RDX-Al ( 60/ 24/ 16) . When RDX and aluminum pow der are screened w ith 200 mesh screen and 180 mesh screen respect iv ely , even bet ter r esult s can be o btained. Besides, the above technical measures did not reduce the ov er all quality o f the charge.
