Embodiment 1

[0039] Example 1: Preparation and Product Characterization of Silver Silver Silver

[0040] 10 ml of 0.1 mol / L of silver nitrate solution was prepared, 10 ml of azide solution of 0.1 mol / L, a sodium carboxymethylcellulose solution was formulated, and the sodium carboxymethylcellulose sodium solution was quantified. Sodium nitride solution. Two reaction solutions were placed in the pumping device 1 and the pumping device 2, respectively, and the insection rate was 5.0 ml / min. The temperature control device temperature is set to 65 ° C. When the temperature is heated to the set temperature, the pumping device 1 and the pumping device 2 are opened, and the nitrate silver solution 3 and the azide solution 4 flow into the microfluidic chip 5, silver nitrate solution 3 and the sodium sodium nitride solution 4 The microfluidic chip 5 is internally contacted and the reaction is mixed, and the azide suspension is produced. The azide suspension flowing from the microfluidic chip 5 is ...

Abstract

The present invention relates to a microfluidic-based conventional azide preparation system and a synthesis process. The system comprises: a fluid driving unit which is used for driving a reaction liquid; a crystallization unit which mainly comprises a temperature control device and a micro-fluidic chip, wherein the fluid driving unit drives reaction liquid to be quickly mixed in the micro-fluidicchip and react at the reaction temperature under the action of a micro-mixing structure to generate suspension liquid; and a sample collection unit which is used for collecting the suspension flowingout of the micro-fluidic chip. Based on micro-fluidic control, the required conventional azide can be rapidly prepared by fixing experimental conditions and operating parameters in the reaction process, the prepared product is uniform in crystal form, good in crystal appearance and uniform in particle size distribution, resource waste during traditional high-capacity mixed preparation is avoided,the risk in the traditional preparation process is reduced, The system is safe, environmentally friendly and controllable on the premise of ensuring the product quality, and has favorable economic benefits and application prospects.

Description

Technical field [0001] The present invention relates to the field of fireworks and detonation devices, in particular, a microfluidic conventional stacked nitride preparation system and a synthetic process. Background technique [0002] The azide is a high energy density material that relies widely to its highly efficient gas generating rate and fast energy release, widely used in various fireworks filling and various explosion, whether it is safe production or product quality. They all play a pivotal role. Among them, inorganic laminates, including antitrocking lead, laminated nitridium mercury, laminated silver, laminated copper, superimcium tant cadmium and laminated, all are exploded. Further, the organic laminated nitride such as tritrositridazrose, three-dimiming nitrogen-tri-cyanide, and nitroquis, the lead salts, etc., are also explosive. However, most of them have not been applied due to high cost, too sensitive or stability, etc., which in line with the explosive drugs i...
