Abstract
The invention discloses an igniting agent and application thereof. The igniting agent mainly comprises the following components: 100 parts of 40-200 mesh magnesium powder, 20-80 parts of 100-300 mesh copper oxide and/or ferric oxide, 10-20 parts of nanometer silver powder, 10-15 parts of potassium permanganate and 3-5 parts of nickel powder. The igniting agent provided by the invention is easy to ignite; only an igniting gun can be used for igniting and no special equipment is required; the reaction can be finished within several seconds and the igniting agent can quickly cool; the igniting agent can be widely applied to the welding for a copper-clad steel grounding net of occasions such as a power plant, a transformer substation and the like; and furthermore, the ignition reaction speed is suitable, the heat emission is small and the noise is low.
Description
Technical field
The invention belongs to metal solder field, be specifically related to a kind of detonator of exothermic welding flux.
Background technology
Along with the development of national economy, increase the demand of electric power, power grid construction paces are accelerated, and newly-increased circuit is on the increase.In power transmission network, the earthing or grounding means of each transformer station, electric power pylon, power plant etc. is just obtaining everybody and is paying attention to widely, and its construction quality is not only related to the security of operation of substantial equipment in electrical network, is also related to the personal safety of operation power personnel.Good as a kind of corrosion resistance, earthing material with low cost, copper covered steel composite is just generalized in the application of grounded screen widely.
Because grounded screen lays environment many places in remote districts, field, environment is comparatively severe, and traditional arc welding, gas welding are limited by welding equipment more and transport the restriction of carrying.Equipment is simple, small investment because having for heat release welding technology (exothermic welding), and weld job soon, does not need large power supply, the feature such as simple to operate, and is applicable to the welding of grounded screen joint.
At present, the detonator of exothermic welding flux mainly contains two kinds, and one is made up of magnesium powder, potassium chlorate, pure copper powder, silicon calcium powder, and another kind is made up of iron oxide, aluminium powder, potassium chlorate, potassium bichromate, zinc oxide, glass dust, sulphur, dextrin, winter ancient glue.All containing potassium chlorate in these two kinds of detonators, potassium chlorate is poisonous and have explosivity, and it and organic matter grind altogether and will set off an explosion; Rear a kind of detonator is also containing potassium bichromate and sulphur, and potassium bichromate has superpower oxidisability and toxicity, and sulphur has explosivity, and sulphur, potassium chlorate, glass dust mixing composition are exactly a soil grenade processed.These detonators there is explosive hidden danger and poisonous be not easy to store, transport, use.
Summary of the invention
The object of the present invention is to provide a kind of detonator of exothermic welding flux, the defect such as low with the efficiency of igniting overcoming existing detonator, welding heat is high, welding noise is large.
Detonator provided by the present invention is mainly composed of the following components:
100 parts, magnesium powder 40 order-200 order;

Nano-silver powder 10-20 part;
Potassium permanganate 10-15 part;
Nickel powder 3-5 part.
Cupric oxide powder: in the present invention, preferred size is 100 ~ 200 object cupric oxide powders, preferential oxidation degree is the cupric oxide powder of more than 95% simultaneously.
Metal magnesium powder: in the present invention, preferred size is 100 ~ 200 object magnesium metal powder.
Metallic nickel powder (Ni): in the present invention, preferred size is 60 object metallic nickel powders, preferably purity is not less than the metallic nickel powder of 99% simultaneously.
In a preferred embodiment of the present invention, described detonator comprises or does not comprise other component.
The present invention also relates to the application of above-mentioned detonator as the detonator of exothermic welding flux on the other hand.
Compared with prior art, the present invention has following beneficial effect: detonator of the present invention is easy to ignite, and can ignite with lighter, without the need to special installation, reaction can complete within a few second, and can cool rapidly, can be widely used in the copper covered steel grounded screen welding of power plant, transformer station etc.; In addition, ignition reaction speed well, heat release is little, noise is low.
