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 the metal solder field, be specifically related to a kind of detonator of exothermic welding flux.
Background technology
Along with the development of national economy, to the demand increase of electric power, the 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 not only is related to the security of operation of substantial equipment in the electrical network, also is related to operation power personnel's personal safety.Good as a kind of corrosion resistance, with low cost earthing material, copper covered steel composite just are being generalized in the application of grounded screen widely.
Because grounded screen is laid the environment many places in open-air remote districts, environment is comparatively abominable, and traditional arc welding, gas welding are limited by the restriction that the welding equipment transportation is carried more.Heat release welding technology (exothermic welding) is because having simple, the small investment of equipment, and weld job soon, does not need large power supply, the characteristics such as simple to operate, and is applicable to the welding of grounded screen joint.
At present, the detonator that exothermic welding flux is used mainly contains two kinds, a kind ofly is comprised of magnesium powder, potassium chlorate, pure copper powder, silicon calcium powder, another kind ofly is comprised of iron oxide, aluminium powder, potassium chlorate, potassium bichromate, zinc oxide, glass dust, sulphur, dextrin, ancient glue of winter.All contain 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 also contains potassium bichromate and sulphur, and potassium bichromate has superpower oxidisability and toxicity, and sulphur has explosivity, and sulphur, potassium chlorate, glass dust mix and forms is exactly a soil grenade processed.These detonators exist explosive hidden danger and poisonously are not easy to store, transportation, use.
Summary of the invention
The object of the present invention is to provide a kind of detonator of exothermic welding flux, the efficient of igniting that has detonator now is low, welding heat is high to overcome, weld the defectives such as noise is large.
Detonator provided by the present invention is mainly composed of the following components:
100 parts in magnesium powder 40 orders-200 order;
