    Title  Propellant surface deterring processing technology

    Abstract To deter the propellant surface treatment is to improve the combustion performance, access to important technical progressive combustion method. Currently, the traditional deterred technique applies only to single-base propellant plasticizer-free and plasticizer content is low (<15%) of the double-base propellant, for high energy propellant plasticizer content, difficult to solve deterred agents penetrate to the propellant surface to form a concentration gradient and the long-term storage during the conflict between the anti-migration.

      This paper is to discuss the new design and desensitized TPTM with azide reaction of nitramine propellant activity deterred process by liquid phase granular seven holes on the drug for DA deterred, in propellant surface to form a concentration gradient, discussion of different process conditions Effect on the deterred. Closed bomb test results show that desensitized with traditional polyester propellant energy after the PPA reduction deterred more desensitized TPTM new deterred propellant after the energy is essentially the same. Heat accelerated aging test results show that, TPTM anti-migration performance is poor, not suitable for DA desensitized propellant; to TPTM desensitized propellant for the before and after the combustion is essentially the same aging, anti-migration performance is good. Comprehensive comparison of TPTM desensitized propellant for the deterred effect of temperature is 60 ℃, deterred, deterred agent in volume of 3% 1h propellant deterred better overall performance.

    Title  Anti infrared interference materials research

    Abstract In order to study the infrared smoke screen material, this paper first infrared spectral characterization of a variety of common materials, get some common materials in order to understand the infrared spectra, infrared absorption properties of these materials; then the cordierite was prepared, and the study of infrared spectrum, its SEM, particle size and TG, effects of temperature and the change and process change on cordierite prepared, cordierite infrared ceramic material with infrared absorption properties of the prepared; at the same time, in order to enhance the bronze powder as the performance of infrared smoke screen material, SiO2/bronze powder composite particles were prepared by sol-gel method, study process conditions of agitation on the influence of cladding material, and the change of bronze powder composite particles were various properties.
