A research and testing method for detonation velocity tubes

Abstract

This invention discloses a research and testing method for detonation velocity tubes, comprising the following steps: Step 1, point setting; Step 2, point connection; Step 3, influence determination; Step 4, numerical judgment. This invention, by improving the data reading points of the detonation velocity tube and reducing the difference in the sampling test system, comprehensively verifies the detonation velocity test and uses two or more data points to cross-reference the validity of the detonation velocity value. If the data from two points far from the detonating bomb are significantly greater than the values ​​from two adjacent points, the first set of values ​​can be considered significantly affected by the detonating bomb, and this set of data is invalid. If the difference between the values ​​from the second and third sets of data points is less than 200 m / s, it can be considered a valid detonation velocity. If the difference between two adjacent sets of data is large, it can be considered that the explosive stability is insufficient. This method is beneficial for fundamentally solving the evaluation of explosive raw material performance and simultaneously reducing the significant error brought by the detonation velocity of the detonator to the detonation velocity measurement, effectively evaluating the performance and stability of explosives.

Description

Technical Field

[0001] This invention relates to the field of detonation velocity testing technology, specifically to a research and testing method for detonation velocity tubes. Background Technology

[0002] Before using detonation velocity tubes in production, it is necessary to evaluate the detonation velocity and stability of the explosive through detonation velocity testing. New test materials are prepared by testing two or more tubes of explosive. However, there is a tendency for significant data errors between two or more tubes. Due to equipment and sampling system errors, it is impossible to capture valid detonation velocity values. When there are large errors in two or more sets of detonation velocities, it is impossible to determine which tube represents the valid value, thus making it impossible to evaluate the performance and stability of the explosive. Summary of the Invention

[0003] The purpose of this invention is to provide a research and testing method for detonation velocity tubes to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a research and testing method for detonation velocity tubes, comprising the following steps: Step 1, point setting; Step 2, point connection; Step 3, influence determination; Step 4, numerical judgment.

[0005] In step one above, multiple points are first set on the detonation velocity tube and numbered as point A, point B, point C, point D, etc. At the same time, the set points are connected to the interfaces of the two sets of data of the detonation velocity meter.

[0006] In step two above, connecting points A and C, and points B and D, yields two sets of identical and very close data. Connecting points A and D, and points B and C, yields data for points B and C that are contained within the range of points A and D. Through calculation, if the test values ​​for points A and D are much higher than those for points B and C, it can be considered that the detonation velocity of this tube is affected by the detonation velocity of the initiating bomb.

[0007] In step three above, connecting points A and B, and points C and D, we can see that the detonation velocities of points A and B are much higher than those of points C and D, which confirms the influence of the detonator's detonation velocity on the latex matrix test value.

[0008] In step four above, when connecting points A and B, points B and C, and points C and D, if the detonation velocity between points A and B is much greater than that between points B and C, and between points C and D, then it can be considered that the detonation velocities of points A and B are affected by the detonating grenade, and this set of values ​​is invalid.

[0009] Preferably, in step one, the number of interfaces on the detonation velocity meter corresponds one-to-one with the number of points set on the detonation velocity tube, and the number of test points can be increased as needed at the effective detonation distance of the detonating bomb.

[0010] Preferably, in step one, point A is 800mm from the top of the detonation tube, point B is 900mm from the top of the detonation tube, point C is 850mm from the top of the detonation tube, and point D is 950mm from the top of the detonation tube, and the diameter of the detonation tube is 150mm and the length is 1000mm.

[0011] Preferably, in step four, if the segmental detonation velocity error between points B and C, and between points C and D is less than 200 m / s, it can be considered a valid reading.

[0012] Preferably, in step four, if there are large errors in the readings of points B and C, and points C and D, it can be determined that the emulsion explosive has poor stability.

[0013] Preferably, in step four, if point C and point D are larger than point B and point C, the test can be directly considered invalid.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the research and testing method of the detonation velocity tube uses multiple points on the detonation velocity tube to connect and compare two or more sets of data, ensuring the authenticity of the data during the detonation velocity test, reducing systematic errors such as different temperatures, different sensitization effects, and connection errors that may occur in multi-tube sampling; and reducing the loss of multiple tube samples.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-2 The present invention provides an embodiment of a research and testing method for a detonation velocity tube, comprising the following steps: Step 1, setting up the test points; Step 2, connecting the test points; Step 3, determining the impact; and Step 4, judging the numerical values.

[0019] In step one above, multiple points are first set on the detonation velocity tube and numbered as point A, point B, point C, point D, etc. The set points are then connected to the interfaces of the two sets of data from the detonation velocity meter. The number of interfaces on the detonation velocity meter corresponds one-to-one with the number of points set on the detonation velocity tube. Test points can be added as needed at the effective detonation distance of the detonating bomb. Point A is 800mm from the top of the detonation velocity tube, point B is 900mm from the top of the detonation velocity tube, point C is 850mm from the top of the detonation velocity tube, and point D is 950mm from the top of the detonation velocity tube. The diameter of the detonation velocity tube is 150mm and the length is 1000mm.

[0020] In step two above, connecting points A and C, and points B and D, yields two sets of identical and very close data. Connecting points A and D, and points B and C, yields data for points B and C that are contained within the range of points A and D. Through calculation, if the test values ​​for points A and D are much higher than those for points B and C, it can be considered that the detonation velocity of this tube is affected by the detonation velocity of the initiating bomb.

[0021] In step three above, connecting points A and B, and points C and D, we can see that the detonation velocities of points A and B are much higher than those of points C and D, which confirms the influence of the detonator's detonation velocity on the latex matrix test value.

[0022] In step four above, connecting points A and B, points B and C, and points C and D, if the detonation velocity between points A and B is much greater than that between points B and C, and between points C and D, then the detonation velocities of points A and B are considered to be affected by the detonating explosive, and this set of values ​​is invalid. If the segmental detonation velocity error between points B and C, and between points C and D is less than 200 m / s, it can be considered a valid reading. If there is a large error in the readings between points B and C, and between points C and D, then the emulsion explosive has poor stability. If the values ​​at points C and D are significantly greater than those at points B and C, then the test can be directly considered invalid.

[0023] Based on the above, the advantages of this invention are that, in use, it utilizes an improved conventional detonation velocity tube to read different data from multiple points. Through data analysis, it ultimately produces a valuable detonation velocity determination value, ensuring the validity of the detonation velocity test readings. This reduces the errors caused by inconsistencies in multi-tube sampling readings, which prevent the fundamental determination of detonation velocity readings.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
