Nanometer Materials in the Applications of Propellants and Explosives
Firstly, Nanometer metal oxides CuO、 Fe_2O_3、 Bi_2O -3 and PbO was prepared by solid state reaction at room temperature, because these metal oxides are usually used in propellants and explosives. The catalysis of these nanometer metal oxides for AP thermal decomposition was investigated by thermal analysis.
Green technologies to demilitarize propellants and explosives include molten salt oxidation technology for demilitarization products,photocatalyzing process to destruct waste water containing energetic compounds,treatment technologies for recycle,recover and reuse(R~3) of propellants and explosives.
The six techniques,the conformity and exact expression of relative information content of propellants and explosives,the unity of high-energy and high-security,the controllability of energy release,the technique of cleaning combustion and explosive,the extension of physical and chemical action in process of combustion and explosive,non-lethal weapons and chemical warfare agent as basic direction and developed strategy of propellant and explosive in the circumstances of weapon informationization,are presented.
n this paper,the designed method of MIS in scientific research of propellant and explosive industry used FOXBASE is introduced. This system includes contract management,fund management,official document management,achievement management,etc. It has a series of functions of appending,index,statistics,calculating,report forms and data transmitting among department.
This paper enumerates the methods generally used in measuring the thermoexplosion parameters of explosives and propellants at present at home and abroad. The characteristics of the approximately adiabatic system for dynamic measurement of the thermoexplosion parameters of explosives and propellants are discussed, and the scientific character and the practicality of the method are explained.
The paper introduces the implementation of the high accuracy loading control system of the device for friction sensitivity of gunpowder and explosive. The computer-controlled electrohydraulic servo system is designed. Through the feedback information of the high accuracy force sensor and appropriate control tactics,the accurate control of the loading force is implemented, and the demand of the loading force of the device is reached.
The paper mainly introduces the realization of the electrohydraulic system on the high-accuracy angle control of the device for friction sensitivity of gunpowder and explosive. The main strcture of the original device is reserved, and the electrohydraulic computer-control system is designed to realize the automatic hoisting of the swing-hammer. The height of the swing-hammer is made real-time detection through photoelectric coder, and the automatic control of the height of the swing-hammer is realized.
The process involves no alkali metals, chlorides or transition metals such as chromates, and thus produces propellant and explosive grade ammonium perchlorate of high purity and with no associated instability or pollution problems.
Propellant and explosive manufacturers must treat day-to-day waste streams, and the government must treat overage and obsolete rocket motors.
