Abstract

The application of 3D printing technology in the field of explosives has been a research hotspot in recent years. As the most common explosive additive, how to improve the reactivity of aluminum powder has been widely concerned by many scholars. In order to explore the influence of coating modification process on the safety of aluminum powder in 3D printing process, Hartmann tube and Ignition temperature test system were used to study the sensitivity of dust samples to energy and temperature. The results show that the sensitivity of coated aluminum powder to electrostatic energy is significantly reduced, and the sensitivity to temperature is slightly increased. Better modification technology improves the safety of aluminum powder in 3D printing process. And the flame front propagation law is studied, the results show that the modified aluminum powder has more excellent reactivity. It provides basic theoretical data support for the safe application of the modification technology of aluminum powder in the 3D printing process, which has important reference value for the future application research of 3D printing technology in the field of explosives, and is also one of the key development directions in the future. in constructing both.
