Description

Crushing composition using dissociation and gas pressure {A FRACTURING COMPOSITION UTILIZING DISSOCIATION PRESSURE AND GAS PRESSURE}

In the present invention, the size of the flame is reduced by decomposition and vaporization of water vapor bubbles due to high temperature and high temperature during the summit reaction, and the water vapor pressure is limited to the brittle object crushing, so that the high crushing force is maintained by the static propulsive action of the gas pressure generator. The present invention relates to a deflagration crushing composition that can safely crush brittle objects with a dedicated ignition without using an output device.

Oxidation reactions in which combustibles combine with oxygen to form oxides usually combust about 300 m / sec or less, detonate 300-800 m / sec, explode 1000-2000 m / sec, and detonate more than 2000 m / sec depending on the reaction rate. Doing.

Summit is a mixture of metal powders such as magnesium, iron, and aluminum and metal oxides (iron oxide, copper oxide, etc.). It is widely used in various industrial fields such as plasma welding.

Plasma is a term that refers to highly ionized gas that is ionized at very high temperatures. The plasma reacts with the summit agent using high voltage discharge, and is a mixture of metal oxides, metal salts, sulfates, nitrates, etc. It is used for rock crushing by using the pressure of ionized gas which is ionized at very high temperature.

Until now, the rock crushing using the summit agent is Patent 10-0308081, Patent 10-0283505, Patent 0184541 in order to generate a plasma by supplying a high voltage high current to the electrode or the electrode assembly by the high-pressure plasma generated by the reaction heating resistance As a method of crushing rock, the high-voltage large-capacity power shock generating device has a problem in that only a few crushing holes are provided at a time of blasting. In order to compensate for this, the plasma continuous control blasting device of Patent 10-0363017 discharges using a lower voltage than the conventional one, but this also uses a commercially available blasting device such that an electrode must be inserted into the summiting agent in order to react the summiting agent. Has a difficult problem.

In addition, in the plasma wave method using only the summit agent, when the energy due to the reaction of a large amount of electrolytic materials becomes a shock wave, only the solid remains as a product when the rock is broken, and the propulsion is performed by the gas expansion pressure which is absolutely necessary for the movement of the rock during the rock fracture. Since there is no action, the shredding efficiency is lowered. Therefore, in order to solve these problems, the decomposition reaction rate is increased by using the principle that the plasma energy becomes larger when the reaction temperature is high when the plasma of high temperature and high heat (the explosion wave is called shock wave or shock wave), which is the energy source by the reaction of the electrolytic materials, is increased. Efforts have been made to add oxidation promoters and reaction rate increasing agents or to supply high currents through higher voltage high power supplies, but this is also inefficient and limited. To increase the reaction rate, since the composition is changed and the reaction temperature is changed, unreacted substances may remain.

 On the other hand, in the domestic patent 0184541 by mixing the water in the summit agent to make the water acts as a decomposition gas, there is a problem that the performance is easy to deteriorate the moisture is elapsed after the seal.

Patent No. 10-0276128, which supplements the problem of lowering power due to lack of gas pressure when only the solid residue is generated upon decomposition of the summit agent, uses potassium alum, ammonium alum, and nickel sulfate as the thermite and decomposition gas generator. This small water vapor pressure is limited to crushing brittle objects, and in order to increase the propulsive action of gas pressure, which is a static power, a separate gas pressure generator is required to increase the crushing power.

Here, the evaluation of the power of the composition crushing the rock can be expressed through the same method as the power factor calculation method of explosives. There are two important factors in breaking a rock. It is the energy acting on the rock when the composition reacts, namely the dynamic force (destructive action of impact from shock waves) and static force (propulsive action of gas pressure). The academic community reports that about 85% of the static force (propulsive action) works in breaking up rock, and about 15% of the dynamic force (disruptive action) works. Static force (propulsive action) represents the propulsive expansion pressure by gas pressure, and dynamic force (disruptive action) represents shock waves with high temperature and high heat. In other words, this means that if the object is impacted by a large shock wave in a moment by dynamic reaction, breaking the rock (destructive action), then the gas pressure with high temperature and high pressure occurring in the composition is rapidly moved between the broken rocks. As it diffuses and releases (propulsive action), it pushes the rock and breaks it up and breaks it again. It is very important in rock crushing.

The present invention is to solve the above problems, as well as the shock pressure of the shock wave, which is a dynamic force generated during the decomposition of the high temperature and high temperature of the summit, as well as the dissociation pressure of the steam bubbles decomposed by the high temperature and high temperature, It is an object of the present invention to provide a deflagration crushing composition that is safer and better than the conventional plasma technique by increasing the crushing force due to the gas pressure due to the static propulsive action of the gas pressure generator having a large gas cost.

An object of the present invention is to provide a deflagration crushing composition that can significantly reduce the size of the flame by the injection of the vapor pressure of the steam bubble when the dissociation pressure generating agent is decomposed during the summit reaction to improve the safety.

It is an object of the present invention to provide a safe deflagration crushed composition that does not have a transition from deflagration to detonation.

      An object of the present invention is to provide a deflagration crushing composition that does not require a high-voltage large-capacity power shock generating device, the cost is reduced and the operation is efficient.

      An object of the present invention is to provide a ignition ignition that can be ignited even if the existing blasting machine can be used as it is without using a high voltage output device.

When crushing rock, instantaneous high temperature and high temperature is generated by the reaction of oxidizing agent and reducing agent, and when water bubbles in the fine cavity of inorganic compound become more than a certain temperature during composition, the brittle object is rapidly released by the dissociation pressure vaporized and decomposed into steam bubbles. The deflagration crushing composition of the present invention is based on the principle of crushing rock by breaking the rock according to the tensile strength value, and rapidly dispersing the gas pressure generating agent into the crushed rock gap.

In the present invention, water bubbles in the fine cavity of the inorganic energy added to the impact energy of the high temperature and high temperature plasma generated by using the high calorific value generated by the summit reaction and the inorganic compound added to the summit agent are rapidly decomposed and vaporized by steam bubbles at high temperature and high temperature. The thermal dissociation pressure (water vapor pressure) and the static propulsive action of the gas pressure generator make it possible to crush brittle objects.

In order to achieve the above object, the deflagration crushing composition of the present invention is composed of a summit agent, a dissociation pressure generator, a gas pressure generator, and an emulsifier, if necessary, consisting of a reducing agent to which an antistatic agent is added and an oxidizing agent to which a corrosion inhibitor is added.

It is said that crystals will release gas molecules or become solutions and decompose into ions. Especially in case of heat, it is called heat dissociation.

Zeolites used as dissociation pressure generators are called zeolites, meaning "zein lithos" from the Greek etymology, because they generate steam when heated and appear to boil. Zeolite, an inorganic compound, is in a solid state, but when it is above a certain temperature, it is decomposed and vaporized by high temperature and high temperature to show a dissociation pressure. Zeolites include natural zeolites and synthetic zeolites, and contain a large amount of water of 10-18 wt% in the fine pores of the structure, and have excellent adsorption and dehydration functions. Silica gel is a granular amorphous particle with fine pores connected to each other and connected by a massive net. It is excellent in adsorption capacity and is colorless and odorless. It is necessary to surround the microcavity of zeolite and silica gel with microcrystalline wax to maintain water bubbles in the cavity. This makes it possible to prevent freezing of water and to improve the ignition sensitivity. In addition, when the zeolite and silica gel are decomposed and vaporized during the reaction of the summit agent, the flame size is significantly reduced by the injection pressure of water vapor bubbles.

The larger the size of the fine cavity, the higher the ignition sensitivity. Since there is a lot of fine water bubbles in the summit, when the heat source reaches one bubble by the thermal reaction of the summit at the ignition point, the decomposition vaporized water vapor having water bubbles is maintained when the bubble is compressed by energy from the outside. The internal energy (Q, cal) is Q ∝ D³. Where D is bubble diameter. The thermal diffusion rate (q, cal / sec), which is reacted through the bubble boundary of each layer formed in the summit from vapor bubbles generated by decomposition vaporization in zeolite and silica gel, which are dissociating agents, is q ∝ D². . That is, Q / q ∝ D (sec).

It is thought that the larger the size of the water vapor bubble, the higher the reaction layer becomes for a long time, and as a result, the thermal dissociation pressure increases as the temperature rises, and it continues to ignite in each reactant layer to detonate. The larger the diameter, the better the internal energy of the bubble with respect to the thermal diffusion rate. Therefore, the larger the fine cavity size is, the smaller the size of the microcavity does not significantly affect the fracture.

Sodium azide (NaN ₃ ) and dinitrosopentamethylenetetramine (DPT (dinitroso pentamethylene tetramine, C ₅ H ₁₀ N ₆ O ₂ )) used as gas pressure generators are gaseous and the pressure is The constant value is indicated by the reaction temperature. This represents a static propulsive expansion pressure. The static propulsive pressure causes the rock to fracture according to the tensile strength value of the brittle body due to the decomposition vaporization dissociation pressure having high temperature and high temperature, and the gas pressure generating agent rapidly diffuses into the fractured rock gap and pushes the rock at the same time. It breaks apart and also breaks again as the rocks collide with each other and move.

In addition to the gas pressure generator composition described above, nitro compounds having two or less nitro group bonds and a nitrogen content in the range of 12 to 16% may be mentioned. These are mildly explosive and are primarily used as intermediates for dyes and rocket propellants.

The thermodynamic properties of the summit agent are known and the reaction is:

2 Al + Fe ₂ O ₃ → 2 Fe + Al ₂ 0 ₃ (heat value 2691 Kcal / kg)

Or 2 Al + 3/4 Fe ₃ O ₄ → 9/4 Fe + Al ₂ 0 ₃ (heat value 3058 Kcal / kg)

Intense formulation with higher calorific value than above

2 Al + 3 Cu0 → 3 CuO + Al ₂ 0 ₃ (Calorific value 3452 Kcal / kg)

 The stoichiometric ratio of powdered aluminum (Powder Al) and cupric oxide (CuO) is 18.5: 81.5. However, a preliminary test was carried out for the composition of the crushing agent for the purpose of thermal dissociation and gas pressure in addition to the impact of the plasma, which was required for thermal dissociation and gas pressure.

By varying the composition ratio of the summit agent, the rupture and width traces (width traces) of the soft plates were measured by the rupture test of the 25.4 mm steel pipe and the 25 mm vinyl chloride pipe. As a result, the weight percent of Al: CuO = 20 to 25: 75 to 80 in the sand gave the best results. Because of the sealing effect in steel pipes better than vinyl chloride pipes, the width of the sheet was better. The composition of the summit agent is not limited to aluminum powder and cuprous oxide, and any metal oxide may be used instead of cuprous oxide.

As shown in Fig. 5, the ignition apparatus for complexing the deflagration crushing composition is composed of a tube, a ignition agent, a complexing agent, a tackifying agent, an embolus (stopper), a wire, a platinum wire formed at the end of each wire, and a burning device as necessary. Here, the ignition agent, the platinum wire, and each wire constitute an ignition device.

The material of the primer is usually made of aluminum, copper, iron, etc., but this deflagrant crushing agent does not necessarily need the shock wave of the metal fragments of the pipe, and is intended for ignition due to high temperature and high heat generation. The sphere tube may be made of plastic in addition to the tube of metal material.

The ignition device of the ignition apparatus is exposed to a copper wire coating, and the platinum wire is fused to the core wire (each wire), and then mixed with a binder solution made of chlorinated rubber, raw rubber, and benzene based on 10-30 mg of lead mononitroresorcinate as a main component. By rolling the beads around the platinum wire to form an ignition agent, this acts as a mononitroresorcin lead for the first time ignited when the platinum wire is heated by the current supplied from the blasting machine.

The complexing agent of the ignition device serves to facilitate the ignition of the ignition device and the ignition connection of the main complexing agent, and is 0.20 to 0.25 g of lead dinitroresorcinate, and is protected by a separate inner tube in the tube. It is filled directly above the tackifier in the tube.

The complexing agent of the complex is filled with the summating agent (powder Al: CuO = 20-25: 70-75) at the bottom of the tube in the range of 0.8-1.2 g.

In addition, an arbitrary delay time can be set by adding an annual market value including a flame retardant between the ignition agent and the complexing agent.

Embolization was mainly made of polyethylene resin on the ignition device (igniter and platinum wire), and the main line was drawn to the center of the embolus, and the upper part of the tube was crimped with a remedy.

Each wire was coated with PVC with a copper core diameter of 0.45 mm, and a resistance value of 0.1 Ω ± 0.01 per m was used.

In the ignition chain of the complexing apparatus (Ignition chain), the ignition proceeds in the order of supplying current to each wire, platinum wire heating, ignition of ignition agent, combustion of soft reagent, ignition of primary complexing agent, and main complexing agent. In case of recurrence, the burning of the new medicine is omitted.

Examples and comparative examples, the present invention is not limited only to these examples.

(1) reaction rate test

The reaction rate was measured by the optical fiber method using the measuring device shown in FIG. This uses a photodetector element, which has a distance between two points for speed measurement at 100mm (?), Inserts a photodetector line, and connects it to an oscilloscope counter to form a pulse generator of light. In the deflagration decomposition reaction, an electric pulse is generated until it is short-circuited and the oscilloscope records the momentary change of the pulse. When the reaction wave passes between the light detection lines, T (sec) is set and the reaction rate D (m / sec) is set.

The reaction rate was obtained.

(2) 25.4mm steel pipe test

As shown in Figure 2, the outer diameter of 28.7mm, thickness 1.65mm, inner diameter 25.4mm, length 250mm one end of the carbon steel pipe for hydraulic piping is covered with kraft paper and the sample is filled, and then the ignition is attached and 100mm wide, 200mm long and 10mm thick If you erect vertically on the soft plate, you can see the degree of power through the rupture state of the steel pipe, and at the same time, you can check whether the deflagration has propagated to the end by the trace of the soft plate laid on the floor.

 On the basis of the condition of the floorboards, they were divided into clear traces (grade 1), wide traces (grade 2), weak traces and soot (grade 3), and no traces and no soot (grade 4).

(3) ballistic mortar test

As shown in Fig. 3, as a test method to determine the propulsive action of the static pressure gas pressure, about 16.6kg of weight is fired by deflagration of the sample in a sealed state loaded with 10g of sample volume, and further withdraws the reaction. Measure the angle of movement (θ). The ballistic ball ratio is based on TNT (100%), and the value calculated according to the following equation is the ballistic ball ratio.

Tandong gupo rain (%)

= [(1-cos θ) / (1-cos θ _o )] × 100

 θ: shake angle by the sample

θ _o : shake angle by reference drug (TNT)

As shown in Table 1, 1.6 parts by weight of the molten emulsifier microcrystalline wax was added to 80 parts by weight of zeolite, which is a dissociation generator, and mixed well. The mixture was mixed well with 100 parts by weight of the summit (Al: CuO = 20: 80) to which an antistatic agent and a corrosion inhibitor were added, followed by natural drying for 24 hours.

About 150 g of the dried sample was filled in a carbon steel pipe for hydraulic piping having an inner diameter of 25.4 mm, a dedicated ignition was inserted therein, the sample was placed on a sand field, and the reaction rate was measured.

<Example 2>

As shown in Table 1, Example 2 was prepared in the same manner as in Example 1, except that 2.5 parts by weight of microcrystalline wax and 100 parts by weight of zeolite were used. The combustion speed was 227 m / sec, burst in the steel pipe test, and the width traces of the sheet were grade 3. The ballistic ball ratio was 18.4 compared to TNT.

<Examples 3 to 4>

The sodium azide (NaN ₃₎ to the gas expanding agent with the composition of Examples 1 and 2 As shown in Table 1 was added 60~100 parts by weight. The ballistic ball ratio was 21.9 to 36.1% compared to TNT, and the ballistic ball ratio was increased by 30 to 96% compared to Examples 1 to 2 where the gas pressure generator was not added. It can be seen that the propulsion effect is very large.

<Examples 5 to 6>

The composition of the gas pressure generator in the composition of Examples 3 to 4 was changed from sodium azide to dinitrosopentamethylenetetramine [DPT (dinitroso pentamethylene tetramine)], and the same weight part.

<Examples 7-8>

The dissociative pressure was changed from zeolite to silica gel in the composition of Examples 1 to 2 to equal parts by weight.

<Examples 9 to 10>

The gas pressure generator was changed from sodium azide (NaN ₃ ) to DPT in the composition of Examples 7 to 8, and the same weight part was used.

<Examples 11 to 12>

The composition of the gas pressure generator in the composition of Examples 9 to 10 was changed from sodium azide to DPT, and the same weight part.

<Examples 13-14>

In the composition of Examples 1 to 2, 100 parts by weight of the summit agent (Al: CuO = 20: 80) was changed to the summit agent (Al: CuO = 25: 75).

<Examples 15-16>

To the composition of Examples 13-14, 60-100 weight part of sodium azide was added as a gas pressure generator.

Comparative Example 1

Prepare a mixture of 50 parts by weight of salt and 100 parts by weight of 50% by weight of water, and mix it with 100 parts by weight of the summit agent (Al: CuO = 25: 75) to which an antistatic agent is added. After drying for 12 hours under the conditions, the sample was filled with about 150 g of carbon steel pipe for hydraulic piping having an inner diameter of 25.4 mm, and a ignition hole was inserted therein, the sample was placed on a sand field, the reaction rate was measured, and the steel pipe test was performed. Combustion rate was 98m / sec, and half ruptured in steel pipe test. The width trace of smoke was 4 grades, and the salt was half ruptured due to the thermal desalination effect of thermite.

Comparative Example 2

100 parts by weight of wood powder is mixed with 100 parts by weight (Al: CuO = 25: 75) of the summit made with an antistatic agent, and filled with about 150 g of carbon steel pipe for hydraulic piping having an inner diameter of 25.4 mm. The burning rate was measured and the steel pipe test was performed. The rate of combustion was not measurable due to the combustion interruption, half ruptured in the steel pipe test, and the width trace of the soft plate was grade 4. Although wood flour acts as a flammable agent, it is believed that unreacted substances have occurred due to the lack of oxygen supply, which caused the propagation rate to drop significantly.

<Comparative Examples 3 to 4>

It is a test method to see the propulsive effect of static power on the gas diffusion pressure of a sample in a confined space. The ballistic ball test showed that black powder and black vibration crushers were 43.5% and 1.2%, respectively. Compared to TNT, the addition of gas pressure generators increased significantly, resulting in greater static propulsion.

<Comparative Examples 5-6>

The deflagration rate was measured using only 100 parts by weight of Summit (Al: CuO = 20: 80, Al: CuO = 25: 75). The reaction rate was 351 to 384 m / sec. Due to the high reaction temperature, the reaction rate was considered to be ruptured only due to the high pressure or the impact pressure caused by the reaction of the summit. Since there is no gas pressure, the ballistic ball ratio, which is a measure of static power, was insignificant, ranging from 7.1 to 7.6%.

Note) DPT (dinitroso pentamethylene tetramine)

Samples judged to be the best from the results of Examples 1 to 24 were prepared, and the flame length test and the ignition test of the flame were carried out.

(4) flame length test

As shown in Fig. 4, after taking 150g of sample and opening one end of carbon steel pipe for external pipe diameter 28.7mm, thickness 1.65mm, inner diameter 25.4mm, length 250mm and filling the sample, attaching the ignition to one side and igniting The flame comes out on the other side. Attach the vinyl to a certain distance and measure the maximum distance the plastic is melted by the flame. If a hole is made in the vinyl, increase the distance every 5 cm. If the hole is not drilled by increasing the distance, the result is 5 cm plus the distance punched by the vinyl.

(5) Ignition Test

The ignition sensitivity test for explosives indicates whether the reaction continues or unreacted. By the ignition of the ignition apparatus according to the present invention, detonation is carried out five times for each sample, and all five times are ignited to react without leaving unreacted materials.

<Examples 25-28>

In the present embodiments, the complex shown in Fig. 5 was configured to omit the flame retardant, and the complex consisted of a tubular body, an ignition device (including a igniter), a complexing agent, a tackifier, an embolus (stopper), and a wire. . The tubular body is 6.2mm inner diameter, 0.3mm thickness, outer diameter 6.8mm, made of plastic and 40mm in length.The ignition device exposes the core wire by stripping about 7.5mm of the end coating of the electric wire whose core is copper material and exposes the core wire 0.03mm in diameter. Was prepared by fusion of platinum wire. 6 parts by weight of rubber chloride, 2 parts by weight of raw rubber, and 92 parts by weight of benzene were prepared based on 100 parts by weight of the binder solution, followed by mixing well with 100 parts by weight of lead mononitroresorcinate. This ignition agent was applied in a range of about 10 to 30 mg around the platinum wire, spherical shape, and then coated and dried for about 6 hours. 0.8 to 1.2 g of a summit agent (Powder Al: CuO = 20 to 25: 75 to 80), which is a welding agent, is weighed and filled at the bottom of the tube. Fill the bottom of the tube with the complexing agent, and weigh 0.20∼0.25g of lead dinitroresorcinate, which is a complexing agent that easily connects the complexing agent to the ignition device, The inner tube with holes is inserted and pressed together with the complexing agent. In addition, the prepared ignition device was inserted into the tube, closed with a low-density polyethylene material plug (plug), and treated by sealing or crimping around the tube inlet. In addition, an arbitrary delay time can be set by adding a yearly market value to the space between the ignition agent and the complexing agent, but in this embodiment, only recurrence was used.

As a result of applying to Examples <Examples 1 to 24> and <Comparative Examples 3, 5, 6> using the prepared complexing apparatus, all were complexed and detonated, and <Example Sample Classification 16, 18, 22, 24> Separately, the flame length test and the ignition test were performed. As a result, the flame length of the composition to which the dissociation pressure generator and the gas pressure generator were added was 20 to 35 cm. In the ignition test, all five of the five samples were detonated without unreacted materials. It was confirmed that the size of the flame was smaller than that without the dissociation pressure generator due to the injection pressure of the vapor bubbles decomposed by the dissociation pressure generator.

<Examples 29-30>

In order to confirm the change in the flame size through the addition of the dissociation pressure generating agent, the flame size was measured by the composition of the summit agent and the gas pressure generating agent without the dissociation pressure adding agent. The ignition sphere applied in Examples 25-28 was used, and the flame length was 85-95 cm, and the flame length was about three times longer than the addition of zeolite and silica gel, which are dissociating agents, resulting in dangerous exposure to the surrounding combustibles. It was found to be larger and confirmed that the dissociating agent plays a large role in reducing the size of the flame. Five of five samples were detonated in the ignition test.

Comparative Example 7

The ignition spheres applied in Examples 25 to 29 were used, and the composition using only the summit agent showed a flame length of 90 cm in the flame length test, similar to that without adding a dissociating agent.

<Comparative Example 8>

It was detonated with the No. 8 electric primer of the aluminum tube, and the flame length could not be confirmed due to the ignition failure of the composition using only the summit agent. The reason for the ignition failure is that the explosive reaction and the high temperature and high temperature duration are so short that the summit agent is dispersed by the debris impact force. In the ignition test, all five of the five samples failed.

Comparative Example 9

Although 10g of dynamite explosives were attached to the primer of Comparative Example 8, two of the five samples ignited, but only partially reacted with the explosives, and the rest remained unreacted.

Comparative Example 10

The black powder was ignited using the complexing apparatus applied to Examples 25-28. The size of the flame was very large (135 cm), and all five of the five samples were ignited in the ignition test.

Rocks using the conventional summit agent do not generate gas pressure due to solid residues only, or even when generated, there is a phenomenon that the gas pressure drops and the crushing force drops.At the time of the summit reaction, sparks are exposed to contact with flammable substances and explosive gases. There is a phenomenon that can be secondarily propagated by

According to the deflagration crushing composition of the present invention, it is possible to considerably reduce the size of the flame by the vapor diffusion pressure of the water vapor containing water surrounded by the emulsifier to improve the safety. As a deflagration crushing agent, there is no Deflagration to Detonation Transition (DDT) and it is safe. It is ignited by using a dedicated ignition device such as a primer, so it does not require a high-voltage, high-capacity power shock generator, so Reduced work efficiency. In addition, due to the dissociation pressure of water vapor and the static propulsion action of the gas pressure generating agent, in addition to the impact pressure generated during decomposition of the high temperature and high temperature of the summit agent, the crushing force is increased, which is safer and better than the conventional plasma technique and the crushing agent.

To summarize the effects of the present invention,

(1) As a deflagrating crushing agent, there is no deflagration to detonation (DDT).

(2) Small bubbles of water in the cavity of zeolite and silica gel are surrounded by the emulsion, so that water bubbles are stabilized and freeze-preventing effect.

(3) It is possible to crush brittle objects efficiently by using both the decomposed vaporized thermal dissociation pressure and gas generating pressure as well as the impact pressure caused by high temperature and high temperature.

(4) Since the power of the deflagration crushing agent is less than the explosives, noise and vibration are reduced.

(5) Since it can be ignited by using a dedicated ignition device such as a primer, it does not need a high-voltage large-capacity power shock generating device, so that the cost is reduced and work operation is efficient.
