Definitions
- the present invention has been made to solve the problems of the conventional rapid expansion metal mixture described above, the technical problem to be solved by the present invention is to provide a metal mixture blasting capsule that can easily initiate the oxidation reaction by electric spark. .
- the technical problem of the present invention described above is an outer passage, an inner passage accommodated inside the outer cylinder, a space between the solid lubricant powder, which is an anti-friction agent, and a powder between the solid lubricant powder, which is an antioxidation agent, an oxidizing agent, sodium nitrate powder, an oxidizing agent, a ferric oxide powder, an aluminum powder, and a powder.
- It is composed of an inorganic filler powder which is a filler and is filled between the outer cylinder and the inner cylinder, a rapid expansion metal mixture, sodium nitrate powder as an oxidizing agent, ferric oxide powder as an oxidizing agent, copper oxide powder as an oxidizing agent, aluminum powder as a reducing agent and a reducing agent, and It can be solved by a metal mixture blasting capsule consisting of a magnesium powder mixed in a larger weight ratio than an aluminum powder and filled in the inner cylinder, and a metal spark blast capsule including an electric spark generating means recessed in the rapid trigger metal mixture.
- the present invention unlike the conventional electrode is installed only in the interior of the rapid expansion metal mixture, after filling the inner cylinder by selecting only a group of substances (emergency triggered metal mixture) that the metal oxidation reaction is smooth and accurate by the electric spark, Fill the outer cylinder with the expansive metal mixture while the inner cylinder is inserted into the outer cylinder and detonate the sparking metal mixture in the inner cylinder with an electric spark, thereby causing a chain oxidation reaction of the expansive metal mixture in the outer cylinder at a high temperature.
- the triggering of the oxidation reaction of the mixture is greatly improved, and since the same energy can be applied to increase the number of capsules that can be applied at the same time more than 10 times, there is an effect of remarkably improving the workability of the rock site.
- FIG. 1 is a cross-sectional view showing the outer cylinder, the inner cylinder and the electric spark generating means of the metal mixture blasting capsule according to an embodiment of the present invention.
- FIG. 2 is an enlarged view of an important part of FIG. 1.
- FIG. 3 is a cross-sectional view illustrating a state in which the rapid expansion metal mixture and the rapid trigger metal mixture are respectively filled in the outer and inner cylinders of the metal mixture blasting capsule shown in FIG. 1.
- Figure 4 is a cross-sectional view showing the outer cylinder, the inner cylinder and the electric spark generating means of the metal mixture blasting capsule according to another embodiment of the present invention.
- FIG. 5 is a cross-sectional view illustrating a state in which the rapid expansion metal mixture and the rapid trigger metal mixture are respectively filled in the outer and inner cylinders of the metal mixture blasting capsule shown in FIG. 4.
- the solid lubricant powder and the inorganic filler powder are very useful components for the production process of the expanded metal mixture and to prevent air contact, but may act as an obstacle in triggering the oxidation reaction of the expanded expanded metal mixture by electric spark. Therefore, the present invention does not use a rapidly expanding metal mixture for the purpose of triggering an oxidation reaction around the electrode.
- the inner cylinder 7 is filled with a rapid-triggered metal mixture 23 consisting of sodium nitrate powder as oxidant, ferric oxide powder as oxidizing agent, copper oxide powder as oxidizing agent, aluminum powder as reducing agent and magnesium powder as reducing agent.
- the electric spark generating means (11a, 11b, 13) is recessed and installed in the flash metal mixture (23).
- the metal mixture blasting capsule according to the present invention excludes solid lubricants and inorganic fillers around the electric spark generating means (11a, 11b, 13), and has a small amount of oxygen, but oxidizes the copper oxide that gives out oxygen at a relatively low temperature.
- the sparking metal mixture 23 containing a magnesium powder as a reducing agent, which is included in the inner cylinder 7, is included in the fuel cell, and the amount of heat generated during oxidation is relatively low. This allows the oxidation reaction to be triggered very quickly without failure.
- the inner cylinder (1) has a large amount of heat generated during oxidation, but the expansion force is very large, but only the aluminum powder which oxidizes at a relatively high temperature is included as a reducing agent in a large amount to maximize the expansion force of the blast capsule.
- the mixing ratios of the sodium nitrate powder, ferric oxide powder, copper oxide powder, aluminum powder, and magnesium powder constituting the flash metal mixture are 10% to 27% by weight of sodium nitrate powder and ferric oxide powder 15 to the total weight. Wt% to 30 wt%, copper oxide powder 10 wt% to 28 wt%, aluminum powder 5 wt% to 14.99 wt%, magnesium powder 15 wt% to 28 wt%. At this time, the weight ratio of the magnesium powder to the total powder is always higher than the weight ratio of the aluminum powder to the total powder. When the aluminum powder weight ratio is larger than the weight ratio of magnesium powder, the oxidative triggerability is greatly reduced.
- the rapid expansion metal mixture may further include a trace amount (less than 2% of the total mass) of the waterproofing agent. It is preferable to use oil as a waterproofing agent.
- the metal mixture blasting capsule according to the present invention has a hollow cylindrical outer cylinder 1, an outer cylinder upper cap 3 coupled to an upper end of the outer cylinder 1, and the outer cylinder ( It includes an outer cylinder lower cap (5) coupled to the lower end of 1).
- the outer cylinder 1 is short in length, the inner cylinder 7 is coupled to only one end and the other end is sealed by the outer cylinder lower cap 5.
- the center portion of the outer cylinder upper cap 3 is formed in a hollow shape, and the inner cylinder 7 is formed in the center portion of the outer cylinder upper cap 3.
- the inner cylinder upper cap 19 In the inner cylinder 7 and the inner cap upper cap 19, electrodes 11a and 11b fixed by the electrode holder 15 are installed.
- the electrodes 11a and 11b are connected to the DC high voltage generator (not shown) by lead wires 21a and 21b penetrating through the inner cylinder upper cap 19.
- the inner cylinder upper cap 19 is sealed by an electrode holder 15 made of rubber or silicon, and the inner lead upper cap 19 is surrounded by an upper lead wire 21a, 21b by a rubber or silicon lead wire sealing material. Wrapped by (17), it completely blocks air or moisture from entering the inner container.
- the lower end of the inner cylinder 7 is sealed by the inner cylinder lower cap 9a.
- Coupling portion between outer cylinder lower cap (5) and outer cylinder (1), Coupling portion between outer cylinder upper cap (3) and outer cylinder (1), Coupling portion between outer cylinder upper cap (3) and inner cylinder upper cap (19), Inner cylinder upper cap (19) and the coupling portion of the inner cylinder (7) is attached by an adhesive and completely sealed.
- the inner cylinder upper cap 19 After the inner cylinder upper cap 19 is injected, the leader line sealing member 17 and the electrode holder 15 are inserted in the inner cylinder upper cap 19 with the leader lines 21a and 21b and the electrodes 11a and 11b inserted therein. ), The inner cylinder upper cap 19, the lead wires 21a and 21b, the lead wire sealing material 17, the electrode holder 15, and the electrodes 11a and 11b are integrally formed.
- the inner cylinder is coupled to the inner cylinder upper cap 19 in the state in which the rapid trigger metal mixture 23 is filled in the inner cylinder 7, and in this process, the electrodes 11a and 11b are recessed in the rapid trigger metal mixture 23. By doing in this way, the airtightness of the inner cylinder 7 can be ensured completely.
- a resistance line 13 connecting the (+) electrode 11a and the (-1) electrode 11b is connected to the lower ends of the electrodes 11a and 11b, and the DC high voltage generator generates a high voltage of 3K (V) or higher. , 11b), so that the electric wire is generated between the electrodes on both sides as the resistance wire melts.
