Abstract
The utility model provides a composite high-intensity plastic booster, including an external tube, an internal tube and a booster explosives wire which is arranged inside and outside of the internal tube and is made from cotton and booster explosives. The booster explosives are soaked in the fiber of a nitrified cotton rope. After being processed with special techniques, the tensile force of the rope can be 22kg and the tensile strength and the ability to resist bending and high temperature of the booster is enhanced. The cost for raw materials is low and the production technique is simple. The utility model can be widely applied in medium and deep holes explosion projects.
Description
1, technical field
The utility model relates to a kind of combined type highstrenghtpiston's detonator in the engineering explosion.
2, background technology
Plastic detonating tube does not produce characteristics such as vibrations, networking is convenient, security is good and is widely used in the engineering explosion because of its anti-stray electrical and static in the propagation of explosion process.But the stretching resistance of common plastics detonator has only below the 5kg, and anti-bending performance is poor, causes miss-firing at the on-the-spot subject to damage of explosion.Along with no cap-sensitivity bulk explosive applying in the medium-length hole blasting engineering, require to transmit detonate can initiating equipment have strong, the anti-bending of stretching resistance, the characteristics of cracky and heatproof not, and loading wire of electric detonator and common plastics primacord all do not meet above-mentioned requirements; Though industrial detonating fuse can satisfy above-mentioned requirements, in its propagation of explosion process bulk explosive in the hole is had destruction, and the cost height.The characteristics that the high strength detonator has that cost is low, surrounding medium (comprising explosive in the hole) is had no effect in the safety, propagation of explosion process, but existing product exists or tensile strength is not enough, or complex manufacturing, the problem that cost is too high.
3, summary of the invention
Technical assignment of the present utility model provides a kind of tensile strength height, anti-bending is good, production technology is simple, lower-cost combined type highstrenghtpiston's detonator.
Technical assignment of the present utility model is realized in the following manner, this detonating primer is by being made up of outer tube, interior pipe and booster explosive rope, the booster explosive rope is arranged among the interior pipe, the outside of pipe in outer tube is arranged on, the booster explosive rope is to be composited by cotton cord and primer, and primer is immersed among the fiber of nitrated cotton cord.
Combined type highstrenghtpiston's detonator of the present utility model is processed its stretching resistance through special process and can be reached more than the 22kg, has strengthened the tensile strength of detonator and anti-bending, heat-resisting ability simultaneously, and has that the cost of raw material is low, the production technology characteristic of simple.Product of the present utility model can be widely used in the medium-length hole blasting engineering.

Fig. 1 is the overall structure schematic diagram of combined type highstrenghtpiston detonator;
Fig. 2 is a primer rope cross section structure schematic diagram.
In the accompanying drawing, pipe, 3 primers, 4 cotton cords in 1 outer tube, 2.
5, the specific embodiment
Below in conjunction with accompanying drawing combined type highstrenghtpiston's detonator of the present utility model is done following detailed explanation.
Shown in accompanying drawing 1,2, technical assignment of the present utility model is realized in the following manner, this detonating primer is by being made up of outer tube 1, interior pipe 2 and booster explosive rope, manage among 2 in the booster explosive rope is arranged on, the outside of pipe 2 in outer tube 1 is arranged on, the booster explosive rope is to be composited by cotton cord 4 and primer 3, and primer is filled among the fiber of nitrated cotton cord 4.
Cotton cord can use the common cotton cotton rope.
Combined type highstrenghtpiston's detonator of the present utility model, its outer tube and interior pipe are to be made of plastics.
Combined type highstrenghtpiston's detonator of the present utility model, its outer tube and interior pipe are to be made by colored plastic.
Combined type highstrenghtpiston's detonator of the present utility model, its primer is filled among the fiber of common cotton cotton rope
Combined type highstrenghtpiston's detonator of the present utility model is processed its stretching resistance through special process and can be reached more than the 22kg, has strengthened the tensile strength of detonator and anti-bending, heat-resisting ability simultaneously, and has that the cost of raw material is low, the production technology characteristic of simple.Product of the present utility model can be widely used in the medium-length hole blasting engineering.
Combined type highstrenghtpiston's detonator of the present utility model, its production process is same as the prior art.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
