Abstract
A detonator for exothermix flux contains magnesium powder (100 wt portions) and powdered cupper oxide and/or Fe3O4, Fe2O3, or their mixture (80 wt portions). Its advantages are easy preparing, no poison and explosion, and low cost.
Description
The present invention relates to a kind of detonator that is used for exothermic welding flux.
At present, the detonator that exothermic welding flux is used mainly contains two kinds, a kind ofly is made up of magnesium powder, potassium chlorate, pure copper powder, silicon calcium powder, another kind ofly is made up 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; A kind of detonator in back also contains potassium bichromate and sulphur, and potassium bichromate has superpower oxidisability and toxicity, and sulphur has explosivity, and sulphur, potassium chlorate, glass dust combined group achievement are soil system grenades.These detonators exist explosive hidden danger and poisonously are not easy to store, transportation, use.
The detonator that is used for exothermic welding flux that the object of the present invention is to provide a kind of safe being convenient to store, transport, use.
For achieving the above object, the present invention is by the following technical solutions: it mainly consists of: 100 parts in magnesium powder 40 orders-200 order, cupric oxide is or/and 20 parts-80 parts of iron oxide 100 orders-300 order oxygenation efficiency 80%-99.9%, iron oxide is the arbitrary one-component of tri-iron tetroxide and di-iron trioxide or the mixture of arbitrary proportion
Above umber by weight.
Because adopt technique scheme, component of the present invention is simple, preparation is convenient, inexpensive economy, especially have effect to be that said components is nontoxic do not have an explosivity, be convenient to store, transportation, use.
The invention will be further described below in conjunction with drawings and Examples.
