Embodiment 2

[0033] Embodiment 2 provides a real-time online method for safely measuring the frictional electrification voltage value of explosives, which includes the following steps.

[0034] Step (S1): The person in charge of the test confirms that the remote control and recording equipment and the test equipment are both turned off, and pulls out the key of the controllable on-off key of the remote control and recording equipment in his hand. Step (S2) is executed after step (S1) is executed.

[0035] Step (S2): Fixing the explosive on the object platform in the explosion-proof room, so that the friction wheel can effectively contact the explosive. After step (S2) is executed, step (S3) is executed.

[0036] Step (S3): Place the non-contact surface electrostatic voltage sensor at a distance of 2 cm to 10 cm from the explosive, and use a conductive rod to derive the accumulated charge on the surface before the explosive test. Step (S4) is executed after step (S3) is executed.

Abstract

The invention relates to the field of an explosive friction sensitivity test, and provides a real-time online explosive triboelectrification voltage value safe determining method, for safely measuring triboelectrification voltages of packaged explosive. The method mainly comprises the following steps: binding the explosive and installing a friction wheel; setting the friction time and the friction frequency of the friction wheel; and obtaining triboelectrification voltage values of the explosive under different friction time and friction frequencies through acquisition through a non-contact type surface static voltage sensor. According to the technical scheme brought forward by the invention, life safety of personnel is guaranteed, the triboelectrification voltage values of the explosive under stimulation of the different friction time and the different friction frequency in a simulated actual application environment can be obtained in real time in an online mode, the safety risk of explosive throw-away reaction is also put to an end, and besides, remote control and recording equipment and measurement equipment are separate and are stripped and are remotely separated from each other such that great economic loss caused by damage of important instrument equipment due to the reaction of sensitive explosive in a test process is avoided.

Description

technical field [0001] The invention relates to the field of explosive friction sensitivity testing, in particular to a real-time online method for safely measuring the frictional electrification voltage value of explosives. Background technique [0002] Shaped explosives are a special kind of energetic material. In a dry environment, the accumulation of static electricity generated by the friction between explosives and contact objects may make explosives in an unsafe state. Therefore, their safety during manual handling and transportation has attracted much attention. It is necessary to evaluate the electrostatic accumulation law and response characteristics of shaped explosives during the friction process. [0003] At present, there is no instrument and method for directly and safely measuring the triboelectric voltage of shaped explosives. Contents of the invention [0004] 【Technical problems to be solved】 [0005] The purpose of the present invention is to provide ...
