炸药

In this paper, the flame retardation of Amatol, TNT, explosive B, RDX, HMX and plastic bonding explosives manufactured from them are discussed. Several explosives with satisfied flame retardancy and explosion performances were obtained for the first time. Alloy bath method, improved hot wire test and flame test are employed to evaluate fire retardancy of fire retarded explosives.

Results show that the explosion properties of explosive containing 10%-20% RDX excel those of nitrolite, emulsive and mealiness explosive, and the explosion properties of explosive containing 40% RDX are same as those of TNT.

得到两大类型的混合炸药：Ⅰ型混合炸药（含RDX 10%-20%）的综合爆炸性能优于现有的铰梯、乳化及粉状工业炸药；Ⅱ型混合炸药（含RDX 40%）的爆炸性能与TNT相当。

Thermal absorbents and negative catalysts (including char forming promotors) are effective flame retarding additives to explosives. It had been theoretically and practically proved in this paper that it is possible to manufacture flame retarding explosives.
