Problems solved by technology

Because the ammonium nitrate in the expanded ammonium nitrate explosive is expanded, its density is low. On the one hand, the volume power of the product is reduced. On the other hand, the increase in the specific surface area also increases the hygroscopicity of the product. If the processing quality fluctuates, the product’s The storage properties will change; the mechanical sensitivity of powdery emulsion explosives is low, and after being made into latex matrix and then dehydrated into powder, the product cost will be higher, especially the kinetic energy consumption and the investment in disposable equipment.

Abstract

A non-TNT high-energy powder explosive is prepared from composite wax (4-6%), additive (0.5-4%) and ammonium nitrate (rest) through changing the oxidant and combustible agent to liquid state, mixing, airflow atomizing for dewatering, granulating, drying and cooling in sealed water cooler. Its advantages are no environmental pollution, and high explosion power.

Description

technical field [0001] The invention belongs to an explosive and its preparation method, in particular to powdery explosive without TNT and its preparation method. Background technique [0002] At present, in my country's powdery explosives, explosives containing ladders account for about 50% of the total. Although this type of powdered ammonium-ladder explosives has high power, a wide range of raw materials, easy production and relatively safe, TNT is a nitro compound. The physiological functions of the human body are seriously affected, and people who have been exposed to it for a long time will be chronically poisoned and cause blood system diseases; ammonium nitrate has a strong tendency to absorb heat and agglomerate, which not only affects the production, storage, transportation and application of explosive products, but also reduces the explosive performance , or even lose performance. Common powdered explosives that replace powdered ammonium ladder explosives include ...
