Abstract
An inductive explosion non-directional industrial detonating cord for engineering explosion belongs to cord explosion equipment. Comprises a core wire, a core medicine and an inner and outer wrapping layer. The invention is characterized in that: the core explosive is superfine high explosive or sensitized powder high explosive. When the detonating cord is used for networking, the size of an included angle between a blasting branch line and a blasting main line is not limited, the networking procedure is simple and convenient, the mutual inductance performance is good, the inductive blasting is non-directional, and the blasting reliability and safety are improved. The explosion propagation performance, the temperature resistance, the water resistance and the tensile property of the explosion propagation material all accord with the standard of an industrial detonating fuse, and the explosion propagation material is suitable for being widely used in engineering explosion.
Description
The present invention relates to a kind of rope class explosive in the engineering explosion field.
Industrial detonating fuse is reliable because of its propagation of explosion, stretching resistance is strong, acid-proof alkaline is good, high-and low-temperature resistance, easy to use, thus in engineering explosion, be used widely, and the primacord fuse kind is also answered the needs of blasting technology development and is constantly increased, as cotton yarn primacord fuse and plastic detonating cord, general industry primacord fuse and low energy industrial detonating fuse etc.Owing to when these primacord fuses are used for the explosion networking, require the angle of branch line and main line propagation of explosion direction more can not oppositely connect greater than 90 °, promptly feeling quick-fried has directivity to require, therefore pretty troublesome when explosion is networked, and has carelessness will cause miso-fire slightly.In addition, owing to feel the quick-fried directivity that has, with the blasting cap initiation primacord fuse time, the primacord fuse at detonator rear portion left behind, and stays potential safety hazard at the explosion scene.Common plastics primacord fuse and 5g/m that developed recently gets up, the low energy fuse of 3g/m is the core medicine with coarse grain shape PETN or RDX all, can not realize feeling quick-fried non-directional.The external sticking medicine core low energy fuse of moulding of invention in the recent period, as USP4, the sticking medicine core primacord fuse of moulding described in 232606, dose is 0.1～2.0g/m, moulds medicine core density height because of sticking, and has added many non-explosivity materials, so the quick-fried performance of sense descends to some extent, more can not realize feeling quick-fried non-directional.
Purpose of the present invention aims to provide the quick-fried direction-free industrial detonating fuse of a kind of sense, promptly to the angle no requirement (NR) of the propagation of explosion direction of explosion branch line and main line, also can reliably feel quick-fried when oppositely connecting.
The present invention is realized by following technical proposals.Non-directional industrial igniting fuse for sympathetic detonation is by heart yearn 1, core medicine 2, interior looping layer 3, middle looping layer 4, outer looping layer 5 and cover plastic layer 6 outward and form, and it is characterized in that core medicine 2 adopts ultra-fine powdery high explosives or through the powder or granule high explosive of sensitization.After the high explosive superfine grinding, mechanical sensitivity changes very little, and the principle that shockwave (detonation wave) sensitivity improves greatly, under the prerequisite that guarantees production, use safety, superfine grinding by high explosive or add the shock sensitivity that sensitizing agent improves primacord fuse core medicine, and be equipped with suitable looping layer and outer covering layer, and improve the mutual inductance performance of primacord fuse, realize that sense is quick-fried non-directional.
The present invention compares with existing industrial detonating fuse, is characterized in: the mutual inductance performance is good, and the networking formality of having felt quick-fried non-directional, easy has improved the explosion reliability, has eliminated the potential safety hazard at the residual primacord fuse in detonator rear portion.When being used for the networking of bulk blasting double insurance loop, aperture branch line and main line must not be linked to be " fourth " font, reduce the networking workload more than 60%, and the 1m primacord fuse can be saved in every hole.Its explosion transfer performance, heatproof water repelling property, tensile property etc. all meet the industrial detonating fuse standard.
The present invention is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of product of the present invention.
As shown in the figure, the present invention is by heart yearn 1, core medicine 2, interior looping layer 3, middle looping layer 4, outer Looping layer 5, cover plastic layer 6 outward and form. The high explosive average grain diameter that core medicine 2 adopts is 5-50 Tai'an PETN of μ m or RDX RDX or HMX HMX or hexanitro-stilbene HNS, the core medicine can also be Aforementioned high explosive adds sensitizer and forms. Sensitizer is potassium hyperchlorate, lead orthoplumbate, peroxidating Lead, one or both in barium peroxide, aluminium powder, silica flour, titanium valve, zirconium powder, the boron powder. Heart yearn 1 With interior looping layer 3 be cotton yarn, middle looping layer 4 and outer looping layer 5 are cotton yarn or plastic knitting band, and Can only adopt one deck. When the looping layer all adopts cotton yarn, can cancel outer cover plastic layer, outer coating waterproof Coating and make the sense quick-fried non-directional cotton yarn primacord. By the present invention, it is quick-fried to can be made into the above sense of 3g/m Non-directional serial low energy fuse also can be made into the above quick-fried non-directional general industry of sense of 10g/m Primacord.
With embodiment the present invention is further described below.
Heart yearn 1 is three or four three plying cotton yarns, and core medicine 2 is ultra-fine Tai'an PETN, and its median size is 12 μ m, and dose is 5 ± 0.3g/m, and interior looping layer 3, middle looping layer 4 and outer looping layer 5 are cotton yarn, cover high pressure polyethylene plastic 6 outward, and it is thick to be 0.25mm.The primacord fuse propagation of explosion of making is reliable, feels quick-fried non-directional, and explosion velocity is 6000m/s, and stretching resistance is 40kg, and the anti-outlet capacity of heatproof is strong.
