Method for preparing special nanometer aluminum and magnesium powder for bullets

Abstract

The invention belongs to the field of nanoscale metal powder, particularly relates to a method for preparing special nanometer aluminum and magnesium powder for bullets, which improves the killing effect of the bullets. The method comprises the following steps: respectively processing aluminum and magnesium materials into special spherical nanometer aluminum and magnesium powder for bullets at a high-frequency cutting rate of 5500-6000 times per minute at -5 to 0 DEG C, respectively selecting powder materials in which particles (D3=21nm, D25=31.1nm, D50=50nm, D75=76.13nm and D97=100.6nm) are narrowly arranged, then applying anti-oxidation coating and surface-treating to ensure that the surface energy of the powder particle materials is zero. The material prepared by method is used for preparing bullets, and can improve the effective lethality of bullets in the war from original 0.012% to 28%.

Description

technical field [0001] The invention belongs to the field of nano-level metal powders, in particular to a method for preparing special metal nano-aluminum and magnesium powders for bullets. Background technique [0002] At present, the effective means of ending human beings to maintain world peace is still war, and the outcome of a war mainly depends on the core force of war - weapons. [0003] Since the existence of human beings on the earth, for the sake of peace and prosperity, conflicts and wars of different scales between races and regions have never stopped. From primitive tools, cold weapons, hot weapons, nuclear weapons to the current electronic and electromagnetic weapons, etc., the main purpose is to effectively and quickly destroy the other party's vital forces, and to strive for the greatest benefit and long-term peace. For a long time to come, war will still be the main means to maintain world peace and prosperity. Therefore, for this common goal, countries aro...

Problems solved by technology

[0005] At present, the main problems existing in international and domestic individual weapon bullet technology are: the current armed conflicts and small-scale wars in various regions of the world are still dominated by individual weapons. In the gun battles of war, most of the bullets inflicted on the human body are penetrating injuries, and it is difficult to kill them with one shot. Therefore, it cannot cause direct attrition of combatants, which increases the investment in the war and the further loss of time and resources, which also leads to regional The chronic instability and indefinite procrastination of small wars

At present, there is no single-soldier weapon bullet in the world that can hit the upper half of the human body with a single shot, and at the same time, there is no single-soldier weapon bullet that can hit the lower half of the human body to completely disable it.
