摘要:
A method for preparing a pyrotechnic composition which comprises preparing a composition in a gel form using nitrocellulose and a nitro compound other than nitrocellulose, adding an oxidizing agent, a combustible material and a color rendering agent to the composition, followed by mixing, forming the resultant mixture into a desired shape, and then drying; and a pyrotechnic composition obtainable by using the method. This method can be used for simplifying a production process while maintaining the effect of a star and a lance used in a pyrotechnic composition, particularly in a firework composition.
摘要:
The present invention comprises a solid double-base propellant composition having on a weight basis from about 2 to about 23 percent of a light metal fuel, from about 14 to about 35 percent of a particulate solid oxidizer, from about 12 to about 35 percent triaminoguanidinium hydrazinium diazide and from about 30 to about 50 percent of a plasticized nitrocellulose binder.
摘要:
The present invention comprises a solid double-base propellant composition containing on a weight basis from about 5 to about 40 per cent of a crystalline substantially non-solvated aluminum hydride, from about 21 to about 33 per cent nitronium perchlorate and from about 30 to about 60 per cent of a plasticized nitrocellulose binder.
摘要:
A composite, double-base, solid rocket propellant composition which utilizes beryllium hydride as a high energy fuel in combination with a nitro-nitrate ester plasticizer. The particular ester plasticizer used in the propellant composition serves to produce the high non-equilibrium flame temperatures needed for attaining high beryllium hydride combustion efficiencies.
