Description

Technical Field

[0001] The present invention relates to the technical field of microenvironment control for accelerated storage tests, and particularly to a method for controlling the microenvironment of initiating explosive devices during storage. Background Art

[0002] With the in-depth research of technicians on the storage tests of initiating explosive devices, more and more evidence shows that the long-term storage of initiating explosive devices is mainly affected by the temperature, humidity, and volatile atmosphere in the local microenvironment. By simulating the microenvironment of initiating explosive device storage, it is beneficial to more accurately carry out accelerated storage tests. Among them, a large part of the volatile atmosphere in the storage space comes from the non-metallic viscous materials (also known as companion specimens, such as adhesives, greases, paints) around the initiating explosive devices during the storage test. The volatile atmosphere generated by such companion specimens will directly / indirectly affect the performance of the initiating explosive devices. Therefore, accurately simulating the microenvironment of initiating explosive device storage is of great significance for carrying out long-term storage tests of initiating explosive devices.

[0003] Currently, when simulating the microenvironment of initiating explosive device storage, most of the focus is on accurately controlling the temperature and humidity, but the key point of accurately controlling the volatile atmosphere is ignored. Even in some individual solutions, companion specimens are used and can generate a volatile atmosphere (placing a small open bottle filled with adhesive / grease / paint in the storage space), but there is no quantitative control of this microenvironment factor of the volatile atmosphere, and there are no relevant standards and established general methods.

[0004] More critically, the existing solutions cannot always ensure that the volatile atmosphere generated in the storage space is uniform, and cannot ensure the consistency of the microenvironment experienced by a large number of initiating explosive devices and multiple batches of initiating explosive devices during the storage test. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for controlling the microenvironment of initiating explosive device storage, which can at least solve the technical problem of "not quantitatively controlling the microenvironment factor of the volatile atmosphere" existing in the existing solutions.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions.

[0007] A method for controlling the microenvironment of initiating explosive device storage, the steps include:

[0008] Step 1, determine the type of the initiating explosive device and the main microenvironment characteristics it experiences during storage, including temperature, humidity, and volatile atmosphere;

[0009] Step 2, select a viscous substance that can generate a volatile atmosphere on or around the initiating explosive device as a companion specimen;

[0010] Step 3, place the initiating explosive device and the companion specimen with a set weight together in a closed test device;

[0011] Step 4: Set the temperature and humidity inside the closed test device according to the requirements of the accelerated test, and conduct the accelerated storage test of the initiator. During the accelerated test, the microenvironment formed inside the closed test device is the simulated storage microenvironment.

[0012] Furthermore, an initiator placement rack is provided inside the closed test device. The space below the initiator placement rack is used to store the constant humidity solution, and the space above the initiator placement rack can temporarily store the volatile atmosphere.

[0013] Furthermore, to solve the technical problem that "the existing solutions cannot always ensure the uniformity of the volatile atmosphere generated in the storage space and cannot ensure the consistency of the microenvironment experienced by a large number of initiators during the storage test", the initiator placement rack includes multiple layers of thin sheets of the same specification arranged overlappingly, and the upper surface of the thin sheet is used to brush the accompanying test samples.

[0014] Preferably, the upper surface of the topmost thin sheet around each initiator is brushed with a set weight of the accompanying test sample. Each layer of thin sheet adopts a standard thickness and a standard weight, and the thickness of each layer of thin sheet is not greater than 3 mm.

[0015] Furthermore, to ensure the consistency of the microenvironment experienced by multiple batches of initiators during the storage test, after the accelerated storage test of each batch of initiators is completed, first remove the thin sheet brushed with the accompanying test sample, then continue to brush the upper surface of the topmost thin sheet with a set weight of the accompanying test sample, then place the next batch of initiators at the designated position on the initiator placement rack, and then continue to conduct the accelerated storage test.

[0016] Furthermore, multiple rows of strip-shaped grooves are provided on the top plate of the sample placement rack, and through holes communicating with the solution storage part are provided beside each strip-shaped groove; an adjusting plate is provided below the top plate of the sample placement rack, and multiple arc-shaped cylinders are provided on the adjusting plate; arc-shaped grooves are provided on the side wall of the strip-shaped groove, and the arc-shaped cylinders on the adjusting plate can be inserted into the arc-shaped grooves; the strip-shaped grooves are used to place strip-shaped initiator test articles, and when the top wall of the arc-shaped cylinder on the adjusting plate is lower than the upper surface of the top plate, the space directly above the arc-shaped cylinder is used to place column-shaped initiator test articles; the top plate is composed of all the thin sheets and the support plates for carrying the thin sheets, and the holes corresponding to each other on all the thin sheets together form the strip-shaped grooves and the arc-shaped grooves.

[0017] Furthermore, to facilitate the quick replacement of different batches of accompanying test samples and ensure the stability of the accompanying test samples, an adjusting screw is connected to the adjusting plate, and the nut at the top of the adjusting screw can be unscrewed; the adjusting screw is in threaded cooperation with the support plate and penetrates through the top plate. When the adjusting screw is rotated clockwise, the adjusting plate moves upward, and when the adjusting screw is rotated counterclockwise, the adjusting plate moves downward; and when the adjusting screw is rotated clockwise to make the adjusting plate in the upper limit position, the top wall of the arc-shaped cylinder is flush with the upper surface of the top plate.

[0018] Further, a round hole is provided on the support plate, and the hole wall of the round hole and the groove wall of the arc-shaped groove are located on the same circumferential surface.

[0019] Further, there is a notch between the two arc-shaped cylinders used to match the two arc-shaped grooves in the same strip-shaped groove. The outer diameters of the two arc-shaped cylinders are slightly smaller than the diameter of the round hole; the through holes provided on the top plate and the through holes provided on the adjusting plate have the same specifications and are coaxially arranged; the first air flow path is jointly formed by the through hole on the adjusting plate, the space between the top plate and the adjusting plate, the notch and the round hole; the second air flow path is jointly formed by the through hole on the adjusting plate, the space between the top plate and the adjusting plate, and the through hole on the top plate.

[0020] Further, the specific steps for removing the thin slice brushed with the test article include: first unscrewing the nut on the top of the adjusting screw, then taking out the thin slice brushed with the test article upward, and then screwing the nut on the top of the adjusting screw back on.

[0021] Beneficial effects: Compared with the prior art, adopting the solution of the present invention can not only quantitatively control the microenvironmental factor of the volatile atmosphere, but also always ensure that the volatile atmosphere generated in the storage space is uniform. More importantly, it can ensure the consistency of the microenvironment experienced by a large number of initiating explosives and multiple batches of initiating explosives during the storage test; adopting the solution of the present invention can ensure that the initiating explosives are affected by the volatile atmosphere of the test article in at least four directions during storage, which is conducive to a more comprehensive analysis of the influence of the volatile atmosphere on the initiating explosives; adopting the solution of the present invention, without replacing the sample placement rack, is not only applicable to controlling the microenvironment experienced by columnar initiating explosives, but also applicable to controlling the microenvironment experienced by strip-shaped initiating explosives, and can also control the microenvironment experienced by columnar initiating explosives and strip-shaped initiating explosives at the same time; adopting the solution of the present invention also facilitates the quick replacement of test articles of different batches and ensures the stability of the test articles, which is conducive to the quick connection of batch tests.

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. However, the descriptions of the following embodiments are only used to help understand the principle and core idea of the present invention, and do not limit the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, improvements made to the present invention without departing from the principle of the present invention also fall within the protection scope of the claims of the present invention. Embodiment

[0032] First, the closed test device used in the present invention will be described. As Figures 1 to 10 The shown closed test device includes a box body 1. A sample placement rack 2 is arranged in the inner cavity of the box body 1. A solution storage part is arranged below the sample placement rack 2 (the sample placement rack 2 divides the inner cavity of the box body 1 into two spaces. The space 30 below the sample placement rack 2 is the solution storage part, and the space above the sample placement rack 2 is a volatile atmosphere temporary storage space). The solution storage part is used to store a constant humidity solution (glycerol aqueous solution or saturated brine solution); A micropore with a diameter not greater than 2 mm is arranged on the box body 1. This micropore is used to connect the internal and external environments of the box body 1 (the function of this micropore is to prevent the pressure in the inner cavity of the box body 1 from being too high, that is, to keep the inside of the box body 1 at normal pressure).

[0033] Combined with Figure 2As shown, the sample placement rack 2 is composed of a frame 28, a top plate with a lifting rod 5, an adjustment plate 22, and an adjustment screw assembly. The top plate and the adjustment plate 22 are stuck inside the frame 28. The frame 28 is used to rest on the support platform 53 on the inner wall of the box body 1. Specifically, the groove 54 at the lower part of the frame 28 is just stuck on the support platform 53, and the side wall of the frame 28 is in contact with the inner wall of the box body 1. Multiple rows of strip-shaped grooves 20 are provided on the top plate of the sample placement rack 2, and through holes 4 communicating with the solution storage part are provided beside each strip-shaped groove 20. An adjustment plate 22 is provided below the top plate of the sample placement rack 2, and multiple arc-shaped columns 23 are provided on the adjustment plate 22. Arc-shaped grooves 24 are provided on the side wall of the strip-shaped groove 20, and the arc-shaped columns 23 on the adjustment plate 22 can be inserted into the arc-shaped grooves 24. The strip-shaped grooves 20 are used to place strip-shaped pyrotechnic test articles (referred to as pyrotechnics for short). When the top wall of the arc-shaped column 23 on the adjustment plate 22 is lower than the upper surface of the top plate, the space directly above the arc-shaped column 23 is used to place column-shaped pyrotechnic test articles. Among them, the frame 28 has a bottom plate 52 with a through hole 4. The through hole 4 on the bottom plate 52, the through hole 4 provided on the top plate, and the through hole 4 provided on the adjustment plate 22 have the same specification and are coaxially arranged. The adjustment plate 22 can just rest on the bottom plate 52.

[0034] In this embodiment, in combination with Figure 2 , Figure 3 and Figure 7 As shown, the top plate is jointly composed of multiple overlapping thin sheets 17 and a support plate 19 for carrying the thin sheets. The thin sheets 17 are placed on the support plate 19. The holes corresponding to each other on all the thin sheets 17 jointly form the strip-shaped groove 20 and the arc-shaped groove 24. The thickness of each thin sheet 17 is 2 mm, and each thin sheet 17 has a standard weight. After all the thin sheets 17 are overlapped together, a top plate with a strip-shaped groove 20 and an arc-shaped groove 24 is formed. A round hole 27 is provided on the support plate 19, and the hole wall of the round hole 27 and the groove wall of the arc-shaped groove 24 are located on the same circumference.

[0035] In this embodiment, an adjustment screw 25 is connected to the adjustment plate 22. A nut 18 is fitted on the adjustment screw 25. A circular limit platform 29 is provided at the bottom of the adjustment screw 25. The limit platform 29 is just located in the circular groove at the bottom of the adjustment plate 22, and the bottom wall of the limit platform 29 is flush with the bottom wall of the adjustment plate 22. The lower part of the adjustment screw 25 passes through the hole 55 on the lug on the adjustment plate 22 and has a clearance fit with the hole 55. The middle part of the adjustment screw 25 is in threaded fit with the threaded hole on the lug on the support plate 19 and penetrates through the top plate. The upper middle part of the adjustment screw 25 has a clearance fit with the hole on the lug on the thin sheet 17. When the adjustment screw 25 is screwed clockwise, the adjustment plate 22 moves upward. When the adjustment screw 25 is screwed counterclockwise, the adjustment plate 22 moves downward. And when the adjustment plate 22 is in the upper limit position by screwing the adjustment screw 25 clockwise, the top wall of the arc-shaped column 23 is flush with the upper surface of the top plate.

[0036] In this embodiment, in combination withFigure 4 As shown, there is a notch 26 between two arc-shaped columns 23 for matching two arc-shaped grooves 24 in the same strip-shaped groove 20. The lateral opening of the notch 26 is arranged in the same direction as the length direction of the strip-shaped groove 20. The diameters of the two arc-shaped columns 23 are slightly smaller than the diameter of the round hole in the bottom wall of the strip-shaped groove 20 (substantially, a notch 26 is formed on a cylinder, thus forming an arc-shaped column 23 as shown in Figure 4 As shown. The diameter of the cylinder is slightly smaller than the diameter of the round hole in the bottom wall of the strip-shaped groove 20. "Slightly smaller" means that the diameter difference between the two is 3 - 5 mm).

[0037] In this embodiment, a first air flow passage is jointly formed by the through hole 4 on the bottom plate 52, the through hole 4 on the adjusting plate 22, the space between the top plate and the adjusting plate 22, the notch 26 and the round hole 27, that is, Figure 1 as shown by the short arrow in Figure 1 ; A second air flow passage is jointly formed by the through hole 4 on the bottom plate 52, the through hole 4 on the adjusting plate 22, the space between the top plate and the adjusting plate 22, and the through hole 4 on the top plate, that is,

[0038] as shown by the long arrow in

[0039] In this embodiment, a through hole 4 is arranged between adjacent strip-shaped grooves 20 in the same horizontal row. The sample placement rack 2 is placed in the middle of the box body 1. The distance between adjacent strip-shaped grooves is 15 mm. All strip-shaped grooves 20 have the same specifications, all through holes 4 have the same specifications, all round holes 27 have the same specifications, all notches 26 have the same specifications, and all arc-shaped columns 23 have the same specifications. Figure 7 When placing the initiator, three schemes can be adopted: Scheme 1, clockwise rotate the adjusting screw 25 to make the adjusting plate 22 rise to the upper limit position. At this time, the top wall of the arc-shaped column 23 is flush with the upper surface of the top plate, and the notch 26 between the two arc-shaped columns 23 coincides with the strip-shaped groove 20, which is equivalent to the arc-shaped column 23 being completely fitted in the arc-shaped groove 24. The strip-shaped groove 20 is a rectangular groove, as shown in Figure 10As shown in the figure, in this case, only the cylindrical initiator needs to be placed in the arc-shaped groove 24 and the round hole 27, and it is supported by the top wall of the arc-shaped column 23. Solution three: Rotate the adjusting screw 25 counterclockwise to make the adjusting plate 22 reach the position where "the top wall of the arc-shaped column 23 is higher than the bottom wall of the strip-shaped groove 20 and lower than the upper surface of the top plate". At this time, the upper part (or part) of the arc-shaped column 23 is fitted in the arc-shaped groove 24. Then, the long strip-shaped initiator can be placed in the strip-shaped groove 20 and the notch 26 first (equivalent to placing the long strip-shaped initiator in the strip-shaped groove 20 and passing through the notch 26), and then the cylindrical initiator is placed in the arc-shaped groove 24 and is supported by the top wall of the arc-shaped column 23.

[0040] Next, the control of the microenvironment for initiator storage using the closed test device in this embodiment will be described.

[0041] A method for controlling the microenvironment of initiator storage includes the following steps:

[0042] Step 1, determine the type of initiator and the main microenvironmental characteristics it undergoes during storage, including temperature, humidity, and volatile atmosphere;

[0043] Step 2, select viscous substances (such as adhesives, greases, paints) that can generate volatile atmosphere on or around the initiator as co-tested samples;

[0044] Step 3, place the initiator and the co-tested samples with a set weight together in the closed test device of this embodiment; the set weight of the co-tested samples is determined by those skilled in the art according to the local environment where the initiator is actually stored during the storage process, the acceleration ratio, and the contact area between the co-tested samples and the initiator.

[0045] Specifically:

[0046] Step 31, first unscrew the nut 18 at the top of the adjusting screw 25, then take out the topmost thin sheet 17 upward, then brush one or more layers of co-tested samples on the surface of the thin sheet 17, and weigh the thin sheet 17 with the co-tested samples. When its weight reaches the sum of the standard weight of the thin sheet 17 and the set weight of the co-tested samples, the requirement for the dosage of the co-tested samples is met. Then, reinstall the thin sheet 17 with the co-tested samples and screw the nut 18 at the top of the adjusting screw 25 tightly. Subsequently, the first batch of initiators can be placed in the strip-shaped groove 20.

[0047] Step 4, set the temperature and humidity in the closed test device according to the requirements of the accelerated test, and conduct the accelerated storage test of the initiator. During the accelerated test process, the microenvironment formed in the closed test device is the simulated storage microenvironment.

[0048] After the storage test of the first batch of initiators and detonators is completed, first unscrew the nut 18 at the top of the adjusting screw rod 25, then take away the thin sheet 17 coated with the companion specimens on the sample placement rack 2 upward, and then take out the topmost thin sheet 17 without companion specimens on the sample placement rack 2 and brush the companion specimens and place the second batch of initiators and detonators according to step 31. During the implementation process, a brand-new thin sheet 17 can be supplemented under the thin sheet 17 coated with the companion specimens each time the thin sheet 17 coated with the companion specimens is replaced, or multiple brand-new thin sheets 17 can be supplemented under the thin sheet 17 coated with the companion specimens after multiple thin sheets 17 are used.

[0049] In another embodiment, multiple thin sheets 17 coated with companion specimens can be pre-sealed with a film and then stacked into a top plate. After the storage test of each batch of initiators and detonators is completed, the topmost thin sheet 17 is taken away, and at the same time, a thin sheet 17 coated with companion specimens is opened to carry out the storage test of the next batch of initiators and detonators. This solution is mainly applicable to the situation where multiple batches of initiators and detonators of the same specification are stored and tested intensively in a short period.

[0050] During the implementation process, a layer or multiple layers of companion specimens are brushed on the upper surface of the thin sheet 17 with a brush. To prevent the companion specimens from dripping, a blank area of 2-3 mm can be reserved at the contour edge of the thin sheet 17. In this embodiment, the thin sheet 17 is made of stainless steel material, and its upper surface is a rough surface with Ra12.5-25, or the thin sheet 17 is made of a wooden board with a thickness of 3-5 mm and no adhesive, or the thin sheet 17 is made of paper with a thickness of 1-2 mm.

[0051] Adopting the solution in this example can not only quantitatively control the microenvironment factor of the volatile atmosphere, but also always ensure that the volatile atmosphere generated in the storage space is uniform. More importantly, it can ensure the consistency of the microenvironment experienced by a large number of initiators and detonators and multiple batches of initiators and detonators during the storage test; adopting the solution in this example, when the initiators and detonators are placed according to the aforementioned solution two and solution three, it can ensure that the initiators and detonators are affected by the volatile atmosphere of the companion specimens in at least four directions during storage, which is beneficial to a more comprehensive analysis of the impact of the volatile atmosphere on the initiators and detonators; adopting the solution in this example, without replacing the sample placement rack, it is not only applicable to controlling the microenvironment experienced by cylindrical initiators and detonators, but also applicable to controlling the microenvironment experienced by strip-shaped initiators and detonators, and can also control the microenvironment experienced by cylindrical initiators and detonators and strip-shaped initiators and detonators at the same time; in addition, it is also convenient to quickly replace the companion specimens of different batches and ensure the stability of the companion specimens, which is beneficial to the rapid connection of batch tests.
