Abstract

In order to obtain the pattern of moulding powder pressed explosives formability, the effects of pressurisation temperature, pressurisation pressure, pressurisation rate, holding time and moulding powder particle size on charge density were studied. The relative density of the pillar can be increased by about 2% by increasing the press temperature by 45ºC; the press pressure is positively correlated with the press pressure within a certain range of variation, and when the pressure increases to a certain value, the density increases slowly; the slower the press punch falls, the higher the yield and goodness rate is. The compression rate of 0.5mm/s can make the yield and good quality rate of the pillar reach 100%; increasing the holding time can improve the density of the pill; the density of the pillar is larger and then decreases as the particle size becomes larger.
