Definitions
- the present invention refers to a thermal spark conductive tube, applied as a signal transmitter for connection and initiation of explosive columns, usually supplemented by a retarding fuse or used as a retarding unit, which employs pyrotechnic mixing.
- low-toxicity nanometer with superior thermal performance of the spark which maintains the advantages of the current pyrotechnic shock tube over the shockwave conduction tube, ie product with higher transmission sensitivity and sensitivity, maintenance of propagation even with cuts or pipe holes and low risk classification in pipe transport and process with possibility of continuous and separate dosing of non-activated components, concomitantly with the formation of the plastic tube and has additional advantages of reducing or even eliminating the use of water contaminants groundwater, lower risk of lead to an electrostatic discharge from the human body to its end, and to use the process of producing the pyrotechnic mixture quite simple and with less risk of accidents due to friction and mechanical shocks.
- U.S. Patent No. 3,590,739 is the original reference for conventional shock tube. Describes a plastic extrusion process forming a circular tube with an outer diameter ranging from 2.0 to 6.0 mm and an inner diameter ranging from 1.0 to 5.0 mm, where continuously and concomitantly secondary explosive dust such as HMX, RDX or PETN or Pentaerythritol or Nitropenta Tetranitrate, previously mixed with Aluminum Powder, on its inner periphery, at the same time as the tube is formed, obtaining a product called non-electric shock tube, found in the market under such trade names. such as NONEL and EXEL, which when initiated by a primary explosive fuse, generates a shock and impact gas wave at speeds of 1,800 to 2,200 m / s;
- NONEL and EXEL which when initiated by a primary explosive fuse, generates a shock and impact gas wave at speeds of 1,800 to 2,200 m / s;
- Applicant's Brazilian patent PI 8104552 is the original reference for the pyrotechnic shock tube. It describes a plastic extrusion process forming a circular tube with an external diameter ranging from 2.0 to 6.0 mm and an internal diameter ranging from 1.0 to 5.0 mm, where pyrotechnic mixing powder K 2 Cr 2 0 is continuously and concomitantly introduced.
- Signal transmission tubes are usually complemented by the insertion of a retarder cap at its end, consisting of a metal capsule containing a secondary explosive layer pressed into it, followed by a primary explosive layer, and a a retarding element consisting of a metal cylinder containing within it a compressed pyrotechnic powder retarding mixing column and often an additional pyrotechnic initiator mixing column sensitive to the heat generated by the percussion and impact wave.
- reaction products generated are basically hot gases which, when exited at the opposite end of the tube, undergo heat loss expansion, which makes it difficult to initiate delayed pyrotechnic mixtures.
- either a sensitive pyrotechnic mixing column is required to continue the explosive train or more longer heat-sensitive pyrotechnic mixtures to be used.
- RDX or Nitropenta in plastic tubes is low, requiring the use of special manufacturing processes and the use of special plastic resins, usually ionomeric polymers such as Surlyn, to minimize the presence of non-adherent powder and avoid unloaded tube portions;
- the conventional shockwave conduction tube has low sensitivity of energy transmission through a gap between two air gap aligned tube portions, generally smaller than 1 cm, so that any cuts or holes in the tube failures due to loss of shock wave pressure;
- Iomeric resins represent a high cost relative to more common resins such as polyethylenes;
- Tube deflagration velocities range from 1800 to 2200 m / s according to the specifications released by the manufacturers, ie +/- 10% around the average velocity, which interferes with the accuracy of the delay element.
- US patents 5, 173,569, 5,435,248, 5,942,718, and Brazilian patents PI9502995 use a shock tube as an electronic delayed primer primer.
- Such fuses are characterized by a high precision electronic delay element, but the delay time error of a given tube length is incorporated into the error inherent in the electronic circuit.
- the pyrotechnic shock tube has the following disadvantages:
- the plastic tube extrusion process involves the dosing of the previously prepared sensitive pyrotechnic mixture during the formation of the plastic tube, with risks of accidental initiation and propagation to the remainder of the mixture;
- the plastic tube extrusion process involves dosing the pre-prepared sensitive pyrotechnic mixture during the formation of the plastic tube with risks of accidental initiation and propagation to the remainder of the mixture;
- Tammann that actually worked commercially for the product of the previous invention was inorganic perchlorates, especially potassium perchlorate, which has been the subject of regulatory bans on several countries, such as the US and the European Union, as perchlorates contaminate water sources and may cause methemoglobinemia and hyperthyroidism by eliminating iodine.
- the main target has been explosives based on inorganic perchlorates, mainly explosive emulsions for use in underground mines, which have sodium, ammonium or potassium perchlorate in their formulations;
- Sodium and potassium perchlorates are also in the form of crystalline salts with a very large average particle diameter for direct application to the spark generating mixtures of the previous invention (mean diameter greater than 40 ⁇ ), so that it is Prior micronization (particle diameter reduction) operation is required on mechanical shock micronizers of compressed air jets, in costly multiple steps both in terms of price and energy consumption, until an average particle diameter of 1 , 5 ⁇ or less; and
- the aluminum of the present invention is in electrically insulating form because its particles are coated with a hard (mechanically resistant) desyllic layer (silicon oxide) or electrically insulating aluminum oxide.
- Potassium perchlorate has been eliminated or substantially reduced in the present invention because even low air humidity is sufficient to make pyrotechnic mixtures containing electrically conductive easily ionizable salts to fail the flash-over test.
- the use of the minimum amounts of perchlorate apply mainly in some applications where folding or knotting may occur.
- the object of the present invention has advantages of dispensing the use of Tammann low temperature substance, therefore the pyrotechnic mixture inside it is less sensitive to friction and shock, does not use or allows the substantial reduction of contaminating perchlorates. groundwater, it is approved in the flash-over test, ie it has a lower risk of conducting an electrostatic discharge from the human body to its end, and the process of producing the pyrotechnic mixture is quite simple by simply mixing the components in an elastic polymer ball mill. [047] Several tests were performed to determine the percentage ranges of the components, following name and detailed description of each:
- a 5 m long tube portion is placed between two optical sensors connected to a precision timer.
- the light of the spark as it passes the first sensor starts the timing, and when it passes the second sensor, it stops.
- the propagation velocity is obtained by dividing 5 by the time obtained in seconds.
- the tube is manually pulled by a lever, and when the desired traction effort is reached, the tube is started at one end by a hand trigger with ear plunger. Passage of the spark through the node or failure in continuity of the spark through the node is observed by the relative darkening of the tube in the burnt session. Should the tube fail, a less effort pull will be attempted with a new sample. If the spark passes the knot, a higher effort pull will be attempted on a new sample. The result of the test will be the highest traction in which 5 successive samples run flawlessly.
- a sample of the powder mixture is subjected to the impact of a known free fall weight from a specified height.
- a 30-second long delay time delay element of 9 sec containing slow-delay mixing with no additional primer layer is positioned at the end of a 6 mm crystal PVC hose.
- variable length diameter with the end of a spark conductive tube according to the formulations of the present invention 1 m in length aligned with the other end of the PVC hose.
- Tube to Tube Air Gap Test A 3 m long piece of spark conductor tube is cut transversely into two 1.5 m halves, and these halves are spaced apart by keeping them aligned within an aluminum-shaped guide. "1/2 - reed”. The largest distance the spark, when traversing the free air space between the tube portions, initiates the second portion in 5 successive samples, is noted as "Tube to Tube Air Gap".
- the tube with all the dust removed is rinsed with acetone at a flow rate of 200 ml / min. for 1 min., and in then dried by a flow of dry compressed air of 0,2 Nm 3 / min. at a pressure of 0.5 Nm 3 / min. for a minimum of 3 min. for drying acetone.
- the empty and dry plastic tube is weighed with an accuracy of 0.0001 g.
