Problems solved by technology

[0010] (1) There is no test method for judging the effect of the detonation reaction. The existing detonation test is used to determine whether the detonation occurs and the distance at which the detonation occurs, and it is impossible to judge whether the detonation effect before and after the detonation is enhanced;
[0011] (2) The amount of test charge in the detonation test is different, and the explosive effect is not comparable, so it cannot be used to determine whether the explosive effect after detonation is enhanced

Abstract

The invention discloses an explosive sympathetic detonation reaction effect judgment method which comprises the following steps: by taking a main propellant grain detonation test as a reference, determining an explosion output effect of the sympathetic detonation test; and through shock wave pressure, the size of an explosion fire ball and the deformation degree of a witness plate, judging whetherthe reaction effect of the two explosives after sympathetic detonation is enhanced relative to a single explosive detonation test or not. The problem that an existing sympathetic detonation test cannot judge a reaction result after sympathetic detonation is solved. The method has the advantages of consistent determination test dose, multiple determination parameters, high credibility, and simpleand rapid field arrangement. The method is suitable for judging whether the reaction effect is enhanced after sympathetic detonation of various explosives.

Description

technical field [0001] The present application relates to a method for judging the detonation reaction effect of explosives, which is applicable to the safety evaluation of the detonation reaction of explosives. [0002] technical background [0003] The amount of explosives is a very important parameter when storing and transporting explosives. For a single type of explosives, the amount of explosives can be calculated through simple algebra, but for different types of explosives, the amount of explosives cannot be simply added or converted into TNT equivalent. The core reason for the subsequent algebraic sum is that different explosives may have the effect of superimposing and amplifying the explosion effect when they explode, that is, there may be an effect of 1+1>2. Therefore, at present, it is usually rigidly stipulated which explosives can be mixed for storage and transportation, and which cannot be mixed for storage and transportation. [0004] The danger of mixed ...
