Nano metal powder special for ammunition acceleration

Abstract

The invention relates to nano metal powder, in particular to nano metal powder special for ammunition acceleration, which solves the problem of low emission initial speed of the weapon in the prior art caused by lower emission blasting explosive energy of a common weapon. A zero-border grain cutting production process for the nano metal powder is adopted at the temperature of between 5 DEG C zero and 25 DEG C and comprises the following steps: setting high-frequency cutting times at 4,500 to 5,000 times per minute to produce nano powder or copper powder, sorting powder materials with relatively dispersed grain distribution of D3=15nm, D25=30nm, D50=50nm, D75=70nm and D97=95nm respectively, then performing surface polishing treatment on the sorted aluminum powder or copper powder grains, and forming a layer of anti-oxidation layer on the surface of the powder grains. Proper amount of nano metal powder materials added into the propellant powder of the weapon can increase the initial speed of a bullet body so that the penetrating power of the bullet body is strong and the killing power is high.

Description

technical field [0001] The invention relates to a nanometer metal powder, in particular to a special nanometer metal powder for speeding up ammunition. Background technique [0002] At present, the light weapons, artillery, and missiles in active service in various countries all over the world have the problems of low initial speed and slow flight speed. The existence of these problems is mainly caused by the insufficient instantaneous release energy of the propellant body. At present, the used bullets of light weapons and artillery, the propellant body of artillery shells and the constituent materials of blasting powder bodies are basically chemical powder bodies, which all lack the characteristics of instantaneous energy release. Therefore, the initial velocity of light weapons bullets in various countries in the world is generally low; The initial velocity of the shells of the artillery of various countries is generally at; 442.m / s---1Km / s, such as the initial velocity ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problem in the prior art that the energy of the blasting charge of ordinary weapons is relatively small, resulting in a small initial velocity of weapon launch, the present invention provides a special nano-metal powder for ammunition speed-up.
