Description

Coiling device for ignition wire of self-propagating reactor

Technical Field

The utility model discloses a production technical field who relates to amorphous form boron especially relates to a coiling device from stretchy reactor ignition wire.

Background

The production of amorphous boron is generally based on the reaction of an active metal to reduce boron oxide, a common form of which is the self-propagating reaction: active metal and boron oxide are fully mixed to form a reaction system, a small part of the system is heated by an ignition wire, after the temperature of the reaction system is reached, the part violently reacts to release a large amount of heat, the heat released by the part violently reacts to heat an adjacent part of the system like burning solid flame, a continuously spread burning wave is formed, and the instantaneous temperature can reach 1800K. And finally, completely burning the reaction system to generate the elemental boron and the active metal oxide.

Heating a small part of the system, usually using a phi 2 resistance wire coiled in a spring, is simpler to form and faster than indirect heating, and avoids the mixing of combustion products compared with oxidizing flame heating. As mentioned above, the temperature of the reaction system is very high, the resistance wire can be partially fused and even blown in the material, namely the consumable, and the resistance wire is replaced before the self-propagating reaction is carried out each time.

Commercially available resistance wires are typically wire-shaped and require coiling of the wire into a spring shape prior to replacement of the wire. Because amorphous boron market demand is little, the output is low, because again because the principle of self-propagating reaction, a large amount of materials can be ignited to a resistance wire, consequently also not high to the demand of resistance wire. From the above, the work load of the coiled resistance wire is not large, and the coiled resistance wire can be manually coiled in production. But because the resistance wire itself is harder, consequently need the appurtenance to coil to improve the efficiency of coiling to the resistance wire.
