Method for decreasing sensitivity by coating single-compound explosive with norepinephrine
A technology of norepinephrine and elemental explosives, which is applied in the directions of explosives, non-explosive/non-thermal agent components, non-explosive desensitizers/passivators, etc., can solve the problem of high mechanical sensitivity, and achieve reduced mechanical sensitivity and reaction conditions Mild, friction-reducing effect

Embodiment 1
[0017] (1) Weigh 0.12g Tris (trishydroxymethylaminomethane), measure 100ml water, stir and mix thoroughly, so that Tris is completely dissolved in water, and prepare a solution with a Tris concentration of 10mmol / L and a pH value of 8.5.
[0018] (2) Take 0.5g norepinephrine and add it to the Tris solution prepared in step (1) to prepare a solution with a norepinephrine concentration of 5 mg / ml;
[0019] (3) Add 5.0 g of HMX granules to the norepinephrine solution in step (2), and let stand for 24 hours;
[0020] (4) Washing with water, filtering, separating and drying the HMX particles at a drying temperature of 50° C. to obtain HMX particles coated with desensitization on the surface. like figure 1 and figure 2 as shown, figure 1 Scanning electron micrographs of the surface of uncoated HMX particles, figure 2 It is a scanning electron micrograph of the coated HMX particle surface, which shows a uniform norepinephrine film on the surface. The characteristic drop height...
Embodiment 2
[0022] (1) Weigh 0.24g Tris, measure 100ml water, stir and mix thoroughly, so that Tris is completely dissolved in water, and prepare a solution with a Tris concentration of 20mmol / L and a pH value of 8.9.
[0023] (2) Take 0.5g norepinephrine and add it to the Tris solution prepared in step (1) to prepare a solution with a norepinephrine concentration of 5 mg / ml;
[0024] (3) Add 5.0 g of HMX granules to the norepinephrine solution in step (2), and let stand for 24 hours;
[0025] (4) Washing with water, filtering, separating and drying the HMX particles at a drying temperature of 50° C. to obtain HMX particles coated with desensitization on the surface. The characteristic drop height of HMX is increased from 32.0cm to 48.0cm; the friction sensitivity is reduced from 100% to 30%.
Embodiment 3
[0027] (1) Weigh 0.12g Tris, measure 100ml water, stir and mix thoroughly, so that Tris is completely dissolved in water, and prepare a solution with a Tris concentration of 10mmol / L and a pH value of 8.5.
[0028] (2) Weigh 1.0 g of norepinephrine, add it into the Tris solution prepared in step (1), and prepare a solution whose norepinephrine concentration is 10 mg / ml;
[0029] (3) Add 5.0 g of HMX granules to the norepinephrine solution in step (2), and let stand for 24 hours;
[0030] (4) Washing with water, filtering, separating and drying the HMX particles at a drying temperature of 50° C. to obtain HMX particles coated with desensitization on the surface. The characteristic drop height of HMX is increased from 32.2cm to 46.0cm; the friction sensitivity is reduced from 100% to 30%.
