Problems solved by technology

In addition to nitrocellulose, the main component of the double-base tubular propellant is nitroglycerin, which has high energy, strong toughness, and is not easy to be crushed. The application is dangerous and costly.
Therefore, the application of decommissioned propellants in the field of civilian explosives is mainly single-base propellants, and a large number of decommissioned double-base tubular propellants must be destroyed by open-air incineration and explosion methods. This will not only waste resources, pollute the environment, and may cause serious problems if they are not handled properly. security incident

Abstract

A double base tube-energetic colloid explosive is prepared through using 40-70% of a propellant composed of a retired double-base tubular propellant and a retired single-base granular propellant, 10-30% of ammonium nitrate, 5-20% of sodium nitrate, 0.1-10% of Sesbania cannabina Pers., 0.01-5% of a composite gelling agent and 10-30% of water. The double base tube-energetic colloid explosive is a novel colloid explosive for recycling the retired double-base tubular propellant, has the characteristics of large explosive power, strong water resistance, large density, easy charging, no crystal precipitation and long shelf life, and has the advantages of stable product quality, safe production process, large retired propellant processing capability, diversified variety and wide product application range.

Description

technical field [0001] The invention relates to the technical field of reapplication of decommissioned propellants. In particular, it relates to a civil energetic colloidal explosive manufactured by using decommissioned double-base tubular propellants. Background technique [0002] The application of decommissioned propellants in the field of civilian explosives usually adopts single-base powders, which exist in explosives in the form of pellets or powder. The reason is that the main component of single-base powders is nitrocellulose, which has low energy, brittle texture, and is easy to crush The risk of application is small and the cost is low. In addition to nitrocellulose, the main component of the double-base tubular propellant is nitroglycerin, which has high energy, strong toughness, and is not easily crushed. The application is dangerous and costly. Therefore, the application of decommissioned propellants in the field of civilian explosives is mainly single-bas...
