Description

Penetration force generating device and method for treating explosives using same {Apparatus for Generating Spray Penetration and Explosive Ordnance Disposal Method by Using it}

The present invention relates to a penetrating force generating device and a method for treating explosives using the same.

Through the September 11 terrorist attacks and the Mumbai bombings in India, the international community has declared a war on terrorism and is making every effort to eradicate it. In normal war, most victims are military and military officials, while terrorist targets are mostly innocent citizens.

Terrorists' terrorist tactics include plane terrorism, such as the September 11 terrorist attacks, Taliban suicide bombers and rocket attacks, but most of the bombings are carried out by terrorist-generated explosives, such as the Boston Marathon.

When such explosives are found, military / surface anti-terrorism teams are dispatched to go through the explosives disposal process.

The method of handling explosives by manpower has high processing accuracy and success rate, but there is a fatal problem that can seriously damage the life of EOD personnel if it fails. In the case of the treatment method by machine, the treatment accuracy has increased dramatically by the recent development of mechanical and electronic technology, but the treatment accuracy and the success rate are lower than the treatment of the explosive by manpower, and the explosive treatment machine is very expensive. There is a problem.

In order to solve the above problems, a method of treating explosives using a wide variety of machines has been proposed.

KR Patent Publication No. 10-2011-0085650 (inventive name: water injection launcher) discloses an explosive treatment technology using a grenade launcher shaped water cannon, but it requires a very expensive cost to manufacture the water cannon. There is a problem that the accuracy of handling explosives is reduced by water cannons.

KR Patent Publication No. 10-2001-7000389 (name of the invention: a device for removing a combat means) discloses a device for removing explosives by the penetration force generated by the explosive explosion. However, the above-described apparatus is very dangerous because the explosives are treated by the explosive power of the explosives, and there is a disadvantage in that the manufacturing cost is relatively high.

Numerous papers and patent documents are referenced and cited throughout this specification. The disclosures of the cited papers and patent documents are incorporated herein by reference in their entirety to better understand the state of the art to which the present invention pertains and the content of the present invention.

The present inventors made diligent research efforts to develop an apparatus for treating explosives, which is manufactured in a very inexpensive method, but has greatly increased treatment success rate and safety. As a result, the above-mentioned problems can be completely solved by attaching a dopant wire in a spiral shape to the outer circumferential surface of a conical or truncated cone structure, and then filling the liquid inside the cone or truncated cone and then attaching it to a homemade explosive. The present invention was completed by finding out.

Accordingly, it is an object of the present invention to provide an explosive treatment apparatus.

Other objects and advantages of the present invention will become more apparent from the following detailed description of the invention, claims and drawings.

The present invention provides an explosives treatment apparatus.

The present inventors made diligent research efforts to develop an apparatus for treating explosives, which is manufactured in a very inexpensive method, but has greatly increased treatment success rate and safety. As a result, the above-mentioned problems can be completely solved by attaching a dopant wire in a spiral shape to the outer circumferential surface of a conical or truncated cone structure, and then filling the liquid inside the cone or truncated cone and then attaching it to a homemade explosive. It was confirmed.

According to an aspect of the present invention, the present invention is a conical explosive support having a conical or truncated conical shape; Explosives coupled to the outer peripheral surface of the explosive support; A rear cover covering the portion where the explosives are coupled to the explosive support and coupled to the explosive support; And a front cover covering the bottom surface and coupled to the explosive support or the rear cover.

The term 'penetration force' as used herein may mean a penetrating force.

As used herein, the term 'cone' refers to a surface made up of a line segment of this vertex and each point on the circumference, given a vertex that is not on the plane of the circle, the surface and the first It may mean a three-dimensional figure surrounded by a circle.

As used herein, the term “conical cone” may refer to a figure consisting of a side that does not include a vertex of a cone and a cut surface among two three-dimensional figures formed by cutting a cone into a plane parallel to the base.

The conical or truncated cone-shaped structure used in the present invention has a constant thickness only in the outer circumferential surface thereof, and the inside thereof is empty, so that a liquid or gas may be filled.

It is very important to use a cone or truncated cone shaped structure in the present invention. The reason is that when an explosive force is applied to the outer circumferential surface of the cone or truncated cone shape, a shock wave that imparts a penetrating force may be generated due to the shape characteristic of the structure.

However, the shock wave imparting the aforementioned penetrating force is not necessarily generated by a conical or truncated cone-shaped structure, but is a structure in which the cross-sectional area of the shape increases as it goes down from the upper direction, such as a bell shape or a vulcanized mechanical shape. In all cases, penetration forces occur.

According to a preferred embodiment of the present invention, the cone angle of the structure may preferably be from 60 ° to 180 °, more preferably from 90 ° to 165 °, most preferably 150 °.

As used herein, the term “conical angle” may refer to an angle between any bus bar present in the cone and the bus bar opposite to the bus bar. In the case of a truncated cone shape, the cone angle may not exist, but in the present specification, it is assumed that a curved point exists in the truncated cone shape.

When the cone angle is less than 60 ° or when the cone angle is more than 180 °, the penetrating force is greatly reduced, and the shock wave is not transmitted in a certain direction during the explosion, so that the damage caused by the explosion may increase. do.

The most preferable cone angle in the present invention is 150 ° because the strongest penetrating force and propulsion force using the water jet occur at this angle.

According to a preferred embodiment of the present invention, the internal volume of the structure may preferably be 0.1-100 L, more preferably 0.3-10 L, and most preferably 0.5-3 L.

When the internal volume of the structure is less than 0.1 L or more than 100 L, it is unlikely that it will be actually used considering the size of a conventional commercial explosive. Therefore, the most preferable internal volume of the structure may be 0.5-3 L. It is effective to use 0.5 L structures for handbags or 007 bags, and 2-3 L structures for simultaneous handling of vehicle doors and homemade explosives.

According to a preferred embodiment of the present invention, the explosive is a dopant, and may be formed by winding in a spiral shape on all or part of the side surface of the structure.

The plastic explosives may be applied to the conical structure to manufacture the device of the present invention, but it is most preferable to use a dopant in consideration of manufacturing difficulties and storage difficulties.

The dopant wire is wound around the outer circumferential surface of the structure and is formed in a spiral shape. Even when the wire is wound in a spiral shape, the winding force can be dramatically increased than the winding of the dopant wires at close intervals. This is because when the dopant is ignited, it is observed to burst at the same time with the naked eye, but in reality, a sequential explosion occurs from the part where the electric primer 3 is installed. Because you can't concentrate on that.

According to a preferred embodiment of the present invention, the kind of dopant may be selected from the group comprising preferably 5 g / m, 10 g / m, 20 g / m and 40 g / m.

When the volume of the conical or truncated structure is 0.5 L or less, it is preferable to use 5 g / m dopants, and when the volume of the cone or truncated structure is more than 0.5 L and 1 L or less, 10 g / m dopant is used. When it exceeds 1 L, it is preferable to use 20 g / m or 40 g / m dopant, but it is not limited to this, Various types of dopant can be used according to the objective.

According to a preferred embodiment of the present invention, the amount of the dopant may be preferably 1-10000 g, more preferably 10-2000 g, and most preferably 40-200 g.

When the amount of the dopant is less than 1 g or when the amount of the dopant is more than 10000 g, the explosive force is too small or too large to be used for explosive treatment. Considering that conventional commercial explosives are produced using ordinary suitcases or briefcases, the amount of dopant is most preferably 40-200 g.

According to a preferred embodiment of the present invention, the thickness of the structure may be preferably 0.1 mm to 30 mm, more preferably 0.3 mm to 10 mm, most preferably 0.5 mm to 2 mm. .

If the thickness of the structure is less than 0.1 mm, the thickness of the structure is very thin, it is not easy to manufacture the product, there is a risk of easy breakage during transportation. If the thickness of the structure exceeds 30 mm, the thickness of the structure is very thick, the penetration force during the explosion There is a problem that is significantly reduced.

When considering conical or conical shaped structures that fit the size of homemade explosives, the structural thickness is most preferably 0.5 mm to 2 mm.

 According to a preferred embodiment of the present invention, a liquid may be filled in the conical or truncated conical structure, and the liquid may be water or a viscous liquid.

Such water or viscous liquid is very important in the present invention.

When the water or the viscous liquid is not filled in the conical or truncated cone-shaped structure, the penetrating force is increased compared to the case of filling the water or liquid, but the driving force generated by generating the water jet is water. Or there is a drawback that is significantly reduced compared to the case of filling the liquid.

In general, in order to process the homemade explosives, it is also important to penetrate the homemade explosive case by generating a penetrating force, but more importantly, after passing through the casing, destroy the wire or circuit board of the homemade explosives instantaneously and cause the homemade explosive to explode. It is necessary to completely stop the function of, it is not easy to completely destroy the homemade explosives with a simple penetration force.

When filling the water or viscous liquid inside the structure it is possible to completely stop the function of the explosives by the water jet propulsion generated by the explosion.

According to a preferred embodiment of the present invention, the viscosity of the viscous liquid may preferably be 10-2000 cP, more preferably 100-1000 cP, and most preferably 400-600 cP. .

Filling the structure with viscous liquid instead of water can significantly increase the penetration and propulsion. If the viscosity of the liquid is less than 10 cP has little problem that the viscosity is not given to the liquid does not increase the penetration and driving force, if the viscosity of the liquid exceeds 2000 cP viscosity is so high that the penetration and driving force is rather reduced there is a problem.

As shown in the experimental example described below, when the viscosity of the liquid to be filled is 400-600 cP, the penetration and propulsion force can be significantly increased as compared to using general water.

According to a preferred aspect of the present invention, the penetrating force generating device of the present invention may include a rear cover.

The liquid filled in the rear cover and the rear cover serves to prevent the shock wave generated by the explosion of the dopant line from being dispersed.

However, when the plastic back cover is simply used, the rear cover is completely destroyed when the bombardment line is exploded, so that the shock wave generated by the explosion cannot be effectively prevented from being dispersed.

However, when the rear cover is made of a metal material such as iron or stainless steel, the rear cover may be prevented from being exploded by the explosion of the dopant line, thereby effectively preventing the shock wave generated by the explosion from being dispersed. .

If all the rear cover is made of metal, there is a problem that the manufacturing cost is greatly increased. Therefore, if the rear cover is used in a normal case and a higher penetrating force and a driving force are required, the metal of the metal material that closely bonds with the plastic rear cover is required. It may also be possible to additionally combine the secondary rear cover.

The features and advantages of the present invention are summarized as follows:

(a) the present invention is a conical or truncated conical explosive support with an open base; Explosives coupled to the outer peripheral surface of the explosive support; A rear cover covering the portion where the explosives are coupled to the explosive support and coupled to the explosive support; And a front cover covering the bottom surface and coupled to the explosive support or the rear cover.

(b) When the penetration force generating device of the present invention is used to treat explosives, the explosives treating device can be manufactured at a very low cost (manufacture cost of 10,000 won).

(c) When the penetrating force generating device of the present invention is used to treat explosives, it is possible to protect precious life of EOD personnel because it is treated by explosives by mechanical method.

(d) When the penetration force generating apparatus of the present invention is used for explosives treatment, the success rate of explosives treatment can be increased drastically, and the damage caused by the explosion treatment can be minimized because most of the shock wave propagates only in a certain direction.

Description of Penetration Force Generator

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

39 is a partial cutaway perspective view of the penetrating force generating device according to an embodiment of the present invention.

Referring to FIG. 39, the penetration force generating apparatus 1 according to the exemplary embodiment of the present invention includes an explosive support 10, a dopant line 50, a front cover 60, a rear cover 70, and the like.

Here, the depletion line 50 may be replaced with various kinds of explosives such as Composition-4 Explosives (C4), trinitrotoluene (TNT), and the like.

The dopant line 50 is coupled to and supported by the explosive support 10, which will be described with reference to FIGS. 40 and 41.

FIG. 40 is an exploded perspective view of the penetrating force generating device shown in FIG. 39, and FIG. 41 is a longitudinal cross-sectional view of the penetrating force generating device shown in FIG. 39. It demonstrates with reference to FIG. 40 and FIG. 41 together. For reference, the explosives are omitted from FIG. 40 for convenience of description.

40 and 41, the explosive support 10 has a conical shape with an open bottom surface. The detonation line 50 is coupled to the explosive support ground 11 of the explosive support 10, and the explosive support ground 11 refers to the outer circumferential surface of the explosive support 10 having a conical shape. For reference, the dopant line 50 and the explosive support surface 11 may be coupled using an adhesive or a double-sided tape.

The explosive support 10 may have a different magnitude of load applied to the explosive support 10 according to its size or the weight of the explosive support line 50 to be supported by the explosive support 10. Therefore, the material and thickness of the explosive support 10 can be arbitrarily selected as necessary so that the explosive support 10 can maintain its shape.

For example, the explosive support 10 may be made of a synthetic resin such as polypropylene for convenience of manufacture, and may have an appropriate thickness according to the required rigidity. For example, the explosive support 10 may be manufactured by cutting a pulley propylene sheet of 0.1 to 30 mm thick.

The rear cover 70 is coupled to the explosive support 10 in a shape that covers the explosive support ground 11 of the explosive support 10, that is, the portion where the explosive line 50 is coupled. Injection hole 71 is formed in the explosive support 10, the sealing member 75 and the stopper 73 may be coupled to the injection hole 71, which will be described again below.

The front cover 60 is coupled to the explosive support 10 or the rear cover 70 in a shape to cover the open bottom surface of the explosive support 10. The edge portion of the front cover 60 may be coupled together to the front cover 60 and the explosive support 10, as shown, and, if necessary, to one of the explosive support 10 and the rear cover 70. May be

A space is formed between the explosive support 10 and the front cover 60, which will be referred to as a launch fluid filling space 12.

The volume of the firing fluid filling space 12 may be changed according to the amount of penetration force to be formed by the penetrating force generating device 1, the amount of the dopant line 50, and the like, and the volume ranges from 0.1 to 100 l (liter). It can be formed within.

The launch fluid filling space 12 is filled with a launch fluid (not shown). As the launch fluid, air or a viscous fluid may be used.

Meanwhile, a space is formed between the dopant line 50 and the rear cover 70 coupled to the explosive support ground 11, which will be referred to as a full color space 72.

The rear cover 70 and the color space 72 are for supporting the explosive force so that when the detonation line 50 explodes, tamping, that is, the explosive force is directed in the X direction shown in FIG. 41, the color space 72 is provided. It may be filled with a viscous fluid (not shown) to obtain a sufficient coloration effect.

When the back cover 70 is damaged by the impact transmitted through the viscous fluid filled in the color space 72 when the detonation line 50 explodes, the color rendering effect may be significantly reduced. To prevent this, the rear cover 70 may be made of a high impact resistance metal or a synthetic resin such as polycarbonate.

If the amount of the dopant 50 used is large, that is, if the explosion force of the dopant 50 is expected to be very strong, the auxiliary cover (not shown) may be coupled to the rear cover 70. That is, the auxiliary cover (not shown) is coupled in a shape surrounding the rear cover 70, but the auxiliary cover (not shown) is also made of metal or synthetic resin having high impact resistance, so that the rear cover 70 is exploded by force. It can prevent damage.

Primer 51 is for detonating the dopant line 50, the primer 51 is coupled to one end of the dopant line (50).

Here, one end portion of the dopant line 50 to which the primer 51 is coupled is disposed at the center of the explosive support ground 11, and the dopant line 50 is disposed spirally toward the edge of the explosive support ground 11.

An electric primer may be used as the primer 51, and the primer 51 and the blasting device 53 may be connected to the conductive line 52.

The above-mentioned injection hole 71 is formed to fill the viscous fluid in the color space 72 or to draw the conductive line 52. After filling the viscous fluid in the color space 72, the through hole 76 is formed. Viscous fluid may be prevented from flowing out of the rear cover 70 through the injection hole 71 by using the stopper 73 inserted into the sealing member 75 and the through hole 76 formed. In this case, the stopper 73 may have a drawing hole 74 for drawing the conductive line 52.

The operation of the penetrating force generating device 1 according to the embodiment of the present invention having the structure as described above will be described.

In order to generate a penetrating force using the penetrating force generating device 1, the built-in explosive charge, that is, the dopant line 50 is exploded.

As described above, since the primer 51 is connected to the dopant 50, the detonator 50 may be detonated by operating the blast blast 53 to explode the primer 51.

If the detonation line 50 is detonated by the primer 51, the detonation line 50 will explode from one end to the other end in a short time, so that the detonation line 50 starts from the portion disposed at the center of the explosive support ground 11. Explosion is initiated and propagates to the edge of the explosive support ground 11.

Accordingly, the explosive force generated at the center of the explosive support ground 11 is directed to the direction indicated by X in FIG. 41 by the viscous fluid filled in the rear cover 70 and the color space 72, and the depletion line 50 is The explosive force generated in the process of exploding from one end to the other end is also directed to the X direction by the explosive-condensation support surface 11 having a conical shape.

Therefore, the fluid in the firing fluid filling space 12 is ejected in the shape of a kind of jet stream while puncturing or breaking the front cover 60, so that a very high penetration force is applied toward the X direction.

Such penetrating power can be used for various purposes, such as demolition of a blast pool of a terrorist group and perforation of the entrance and exit of a place where the terrorist group is hiding. It needs to be adjusted to have a size.

The magnitude of the penetrating force is the size of the cone angle θ, whether the material charged in the firing fluid filling space 12 is air or viscous fluid, the viscosity of the viscous fluid filling the firing fluid filling space 12, the explosive ground The amount of the dopant 50 coupled to (11), the dose of the dopant 50 may be changed.

42 to 44 show a modified example of the explosive support shown in FIG.

Referring to FIG. 42, one modification of the explosive support 20 has a truncated cone shape. Therefore, a partially planar portion may be formed in the central portion of the explosive support ground 21. This planar portion may be used for the purpose of easily fixing a primer (see 51 in FIG. 39) connected to one end of the dopant 50.

The explosive support surface 21 of the explosive support 20 may have a conical outer circumferential shape like the explosive support ground 11 described with reference to FIGS. 39 to 41.

Another modification of the explosive support 30 shown in FIG. 43 has a convex curved shape with the explosive support ground 31, and another modification of the explosive support 60 shown in FIG. 44 is an explosive support ground 41. It has a concave curved surface shape.

When the explosive grounds 31 and 41 have a curved shape, the amount of the explosive line (50 in FIG. 1) that can be coupled to the explosive grounds 31 and 41 per unit length is increased, so that the explosives having a relatively small size are increased. It is also possible to obtain the effect of generating a higher penetration force with the support (30, 40).

In addition, the spirally disposed dopant line 50 is a distance from the center of the explosive line ground (31, 41) to the edge of the explosive line ground (31, 41) to rotate one turn, the distance of the The degree of dispersion or concentration of the penetrating force generated by the difference in length may be adjusted by the explosive supporting surfaces 31 and 41 having a curved shape.

Therefore, the explosive support paper surfaces 31 and 41 having an appropriate curved shape can be selected and used according to the degree of concentration or dispersion of the required penetration force.

On the other hand, when a viscous fluid is used as the material to be filled in the firing fluid filling space 12 and the color space 72, water, an aqueous alcohol solution, an aqueous solution of ethylene glycol may be used as the viscous fluid.

Here, alcohol and ethylene glycol are for lowering the freezing point of water, and when the penetration force generating device 1 according to an embodiment of the present invention is used in a low temperature environment, the viscous fluid is frozen to reduce the color rendering effect but generate penetration force. This is to prevent the weakening.

Experimental Example 1 Experiment by Cone Angle

The penetrating and propulsive force (pushing force) tests of the penetrating force generator according to the cone angle were performed. The 5 g dopant used a total of 45 g of 9 g depth lines, and the 10 g dopant used a total of 85 g of 8.5 m dopant lines. The rear cover and / or cone-shaped structure was filled with liquid and used. In the embodiment in which the cone-shaped structure was filled with water, 1 L of water was filled and 2 L of water was filled inside the rear cover. In the embodiment of not filling the conical structure with water, the liquid inlet for the structure is sealed so that water does not enter when the water is filled through the rear cover liquid inlet.

Specific experimental results are shown in Table 2 below (see FIGS. 7 to 34).

Experiments with a cone angle of 60 ° to 120 ° determined that 150 ° was the most appropriate.

Since 1 g of the water to be fired did not sufficiently boost the 5 g / m of the bomber, it was not tested at 5 g / m after 120 °. When manufacturing a penetrating force generating device at 5 g / m, it is preferable to produce a cone-shaped structure to 0.5L or less.

As a result of ultra-high speed camera shooting, the water filled inside the cone-shaped structure is the resistance of the shock wave, or obstacle, caused by the explosion of the bombardment line, and the water only pushes through the iron plate that has not passed through after the shock wave passes through the steel plate. The state played a role. But the force of the water was so great that it was as powerful as a water cannon.

When the explosives were handled, the outer casing of the explosives penetrated the shock wave, followed by water, cutting the various wires in the explosives and destroying BAT.

Experimental Example 2 Experiment by Cone Shape Thickness

The cone angle is 90 °, there is no amount of water to be fired, the amount of water to be colored is 2 L, the amount of dopant is 10 g, 8.5 m, and the thickness of the cone-shaped structure is 1 T to the thickness of 0.5 T in Experimental Example 1 The difference between the fabricated cone-shaped structure and the penetration force was compared. The results are shown in Table 3 below.

Experimental conclusion based on the structure thickness division Angle: 90 ° Angle: 90 ° Structure Thickness: 0.5 T Structure Thickness: 1.0 T Penetrate Push Penetrate Push 1 L 5 g Water × 4 11 - - Water ○ One 16 - - 10 g Water × 6 12 6 14 Water ○ 3 17 - -

The difference in structure thickness is 0.5 T, and this thickness does not significantly affect the penetration force. PP film, which is a material of commercially available conical structure, may have a thickness of 0.5 T or less, but the thickness of the film is not suitable because it is thin and there is no film of 1.0 T or more, so all three types of 0.5 T, 0.8 T and 1.0 T It was okay. However, if the thickness becomes thicker, it is not effective because it becomes the resistance of the shock wave generated by the explosion.

However, it is determined that 0.5T is suitable for small and thin materials and a small amount of dopant, and 1.0T is suitable for a large and large dopant, depending on the explosives.

Experimental Example 3 Experiment According to the Amount of Water Filled

The cone angle is 90 °, the amount of water to be fired is 2 L, the amount of water to be colored is 2 L, the amount of dopant is 10 g, 8.5 m, and the cone-shaped structure is fired in Experimental Example 1 with a thickness of 0.5 T The penetrating structure was compared with the cone-shaped structure made with 1 L of water. The results are shown in Table 4 below.

Comprehensive conclusions about the amount of water fired division 90 ° (1 L) 90 ° (2 L) Penetrate Push Penetrate Push 1L / 2L 5g Water × 4 11 - - Water ○ One 16 - - 10g Water × 6 12 - - Water ○ 3 17 2 17

It is true that the explosive force of the bomber pushes water as shown in FIG. 36, which is a phenomenon analysis using a high speed camera, but before the water pushes, the shock wave penetrates the steel plate first. Compared to the case where the amount of water discharged under the same conditions was 1 L, the number of penetrating longages was insufficient, but the number of pushing in was the same.

However, when comparing the penetrating size, the 2 L penetrating size was 6 cm to 9 cm, but the 1 L penetrating size was 13-20 cm.

Experimental Example 4: Experiment according to the exposure method

The cone angle is 90 °, the amount of water to be fired is 1 L, the amount of water to be transferred is 2 L, and the amount of dopant is 5 g, 2.5 m. The Examples were fabricated in a spiral wound at intervals between the dopants, and the penetration forces were compared. The results are shown in Table 5 below.

Experimental conclusions based on the method division Attach without gap Attach at intervals Penetrate Push Penetrate Push 1L 5g Water × - - - - Water ○ 0 6 0 4 10g Water × - - - - Water ○ - - - -

As a result, the explosive force was superior to the method of attaching the dopant line to the conical structure without any gaps.

Experimental Example 5 Experiment by Liquid Type

The cone angle is 150 °, the amount of liquid to be fired is 1 L, the amount of liquid to be colored is 2 L, the amount of dopant is 10 g, 8.5 m, and the viscosity is 1 cP ), 100 cP, 500 cP and 1000 cP to adjust the penetration test. Starch syrup was completely dissolved in water using a homo mixer, and the viscosity was measured using a viscometer. The results are shown in Table 6 below.

Comprehensive conclusions based on the liquid viscosity used division Explosive power Penetrate Push Liquid 1L fired water 3 20 100 cP 3 21 500 cP 3 22 1000 cP 2 20

Experimental results showed that the penetrating force did not change when viscosity was applied to the used liquid, but the pushing force increased and reached a maximum at 500 cP. However, when the viscosity of the liquid exceeds 1000 cP, the penetrating force and the pushing force decreased. It is considered that the liquid of the sticky substance absorbs the shock wave at the viscosity above 1000 cP.

Experimental Example 6: Experiment using fire extinguisher powder

The cone angle is 150 °, there is no liquid to be fired, the amount of water to be colored is 2 L, the amount of dopant is 10 g, 8.5 m, and instead of the liquid to be fired, the powder for fire extinguisher is filled into the cone-shaped structure to test the penetration force. It was. Experimental results show that the penetration force is 8 sheets and the pushing force is 20 sheets, which is the same as the case without filling the liquid, but the flame generated by the explosion is significantly reduced.

In general, even if the fire extinguisher powder is not used by the water contained in the rear cover, no fire has occurred. However, when the explosive to be treated contains a large number of flammable substances, the use of the fire extinguisher powder is filled with secondary fire prevention. It is preferred for feed.
