Problems solved by technology

However, the chemical properties of the black powder used in the existing fuse are relatively active, and there is a greater danger no matter when it is used for manufacturing or when it is stored in large quantities.
Moreover, the black powder itself will burn or explode violently during use, and it is easy to generate open flames and sparks, and the burning speed is difficult to control. It is more dangerous when used in an explosive environment.

preparation example Construction

[0031] see image 3 and Figure 4, the method for preparing the carbon nanotube linear structure 110 in the embodiment of the present invention mainly includes the following steps:

[0032] Step 1: providing a carbon nanotube array 216 .

[0033] The carbon nanotube array 216 provided by the embodiment of the present invention is one or more of a single-walled carbon nanotube array, a double-walled carbon nanotube array, and a multi-walled carbon nanotube array. In this embodiment, the preparation method of the super-parallel carbon nanotube array adopts the chemical vapor deposition method, and its specific steps include: (a) providing a flat substrate, which can be a P-type or N-type silicon substrate, or can be formed There is the silicon substrate of oxide layer, and the present embodiment preferably adopts the silicon substrate of 4 inches; (b) uniformly forms a catalyst layer on the substrate surface, and this catalyst layer material can be selected iron (Fe), cobalt (...

Abstract

The invention relates to a fuse. The fuse comprises at least one carbon nanotube linear structure, the carbon nanotube linear structure comprises a plurality of carbon nanotubes, the fuse further comprises a material, which is easy to oxidize, coated on the surface of the carbon nanotube linear structure, when one end of the fuse is ignited, the material which is easy to oxide can continuously carry out oxidation along the axial direction of the carbon nanotube linear structure. The invention further provides the exploder adopting the fuse.

Description

technical field [0001] The invention relates to a fuse and an explosive device using the fuse. Background technique [0002] The fuse is a more commonly used transmission wire in the blasting industry, and the fuse is usually connected to the object to be detonated. When in use, the detonator ignites the fuse, and after evacuating from the explosion area, the fuse just detonates the detonated material, thereby preventing personnel from being injured due to untimely evacuation. [0003] The fuse is widely used, usually used in fireworks, mine blasting, mountain blasting and so on. Existing fuses are usually made by wrapping black powder with sandpaper or leather paper, or can also be made by wrapping black powder with cotton yarn. However, the chemical properties of the black powder used in the existing fuse are relatively active, and there is a greater danger no matter when it is used for manufacturing or when it is stored in large quantities. Moreover, the black powder i...
