Problems solved by technology

However, whether it is the huge acceleration and kinetic energy obtained, or the strong external force impact, there are potential dangers for the high polymer bonded explosive samples containing explosives with high content and high sensitivity. Therefore, ultrasonic extraction technology is used in high polymer The pretreatment of polymer-bonded mixed explosive samples has not been applied for a long time. According to the data search conducted by the applicant, no literature reports have been found on the direct application of ultrasonic extraction technology to polymer-bonded mixed explosive samples.

Embodiment Construction

[0022] According to the technical scheme of the present invention, the pretreatment method of the high polymer bonded explosive sample of the present invention comprises the following steps:

[0023] Step 1, processing the same batch of high polymer bonded explosive samples into sample blocks of suitable size;

[0024] Step 2, weighing 0.5000 g of the prepared sample block, and adding it to a stoppered glass container;

[0025] Step 3, measure 30mL of acetone, and add it into the above-mentioned stoppered glass container;

[0026] Step 4, place the stoppered glass container containing the sample and acetone in the ultrasonic instrument, and adjust the power density to not less than 0.2W / cm 2 , not higher than 0.5W / cm 2 , ultrasonic extraction for 15min to 20min;

[0027] Step 5: After the ultrasonic extraction is completed, take out the stoppered glass container to obtain the sample solution; the next step of analyzing the RDX content in the polymer bonded explosive compone...

Abstract

The invention discloses a pretreatment method of a polymer bonded explosive sample. The method comprises the steps of: processing a polymer bonded explosive into a sample block with an appropriate size, conducting ultrasonic extraction in an ultrasonic instrument with acetone for 15min-20min, and adjusting the power density to a range not less than 0.2W / cm<2> and not higher than 0.5W / cm<2>, thus obtaining a sample solution, i.e. able to carry out the next step of ingredient content analysis of the polymer bonded explosive with a routine method. The method of the invention effectively solves the problems of time-consuming pretreatment of explosive samples and poor repeatability of extraction results, and provides reliable data for design and application of explosive formulas.

Description

technical field [0001] The invention belongs to the technical field of explosives, and mainly relates to a pretreatment method for explosives, in particular to a pretreatment method for polymer bonded mixed explosive (PBX) samples. Background technique [0002] Gunpowder can be used as projectile propellant and rocket propellant; explosives can be used in the military as explosive charges for ammunition such as artillery shells, aerial bombs, missiles, mines, torpedoes, and grenades, as well as detonators for nuclear bombs and military blasting. It is widely used in mining, road construction, water conservancy construction, engineering blasting, metal processing, etc., and also widely used in scientific and technological fields such as seismic exploration. In the field of explosives analysis, due to the rapid development of modern analysis technology, the detection breadth, precision and analysis efficiency have been qualitatively improved. However, the sample preparation t...
