Introduction to exothermic flux
Exothermic flux (commonly known as fire mud) is a new type of welding material. Its principle is to use metal oxides. Under high-temperature conditions, a reduction reaction occurs, and the metal is released and becomes liquid metal. Under the wrap of the hot-melt mold, the two metals to be welded are fused together to form a molecular bond with excellent strength and conductive properties. Avoid It has overcome the shortcomings of traditional welding, such as welding slag, welding holes, easy oxidation, low connection strength, and excessive contact resistance. Jitai lightning protection series of exothermic flux
adopts foreign materials specially used for welding railways. The formula contains a variety of trace elements such as,,,, and through strict proportioning, the mechanical strength and oxidation resistance can reach the domestic advanced level. The main composition of Jitai lightning protection exothermic flux is as follows
The main flux is packed in aluminum film bags, and each bag varies in grams.
, igniter, ignites the reaction of the main flux. The igniter includes three materials: It is liquid and packed in bottles.
Accessories include isolators, leak-proof bags, and straws
Technical features of exothermic flux
▲Using high-purity materials, the reaction is complete and sufficient, and the yield is high , does not produce toxic substances
▲Adopts a new ignition system, no ignition gun, no black powder ignition, safe and reliable
▲The generated finished product is composed of a variety of metal elements such as,,,,, high strength, high resistance Low rate
▲The generated copper alloy has good water affinity and can weld any two metals, and is widely used
▲The exothermic flux is vacuum packed and can be stored for a long time
How to use exothermic flux
, Place the two sections of wires that need to be welded into the hot-melt mold, and use the matching mold clamp to close and fix the hot-melt mold.
, Place the isolation piece (metal) in the hot-melt mold. At the bottom of the chamber, seal the liquid guide hole.
Pour the corresponding exothermic flux
into the hot melt mold melting chamber, and use a tool to make the middle of the hot melt solder powder into a semi-concave shape.
, Place the igniter (silver white) in a concave position, and make it on the same level as the main material, with some exposure.
, Close the top cover of the hot-melt mold, and ignite the ignition with a ignition gun When you see the igniter starting to smoke, stay away from the place for more than 1 meter.
About seconds (due to the temperature of the work site and operation reasons, this time is for reference only) Guide the main exothermic flux
to react strongly to produce alloy copper water.
Exothermic flux
Construction method Exothermic flux analysis can effectively reduce the grounding resistance of the ground network. The burial depth must be greater than or equal to
Meters. Adopt vertical embedding, exothermic flux
Adopt horizontal embedding.
Exothermic flux
Use non-metallic conductor materials with stable functions as the conductive medium of the module to conduct electricity. The performance will not be affected by the seasons. The exothermic solder can withstand large power frequency and surge current impact, and the resistance is stable. The distance between modules should not be less than
meters. Exothermic flux analysis module cores must be welded when they are connected in parallel or connected to the ground wire, and the welding area should be more than
times that of the connector.
It can absorb moisture and moisturize, can maintain effective contact with soil, and has low grounding resistance. Welding slag should be removed from the welding joint and anti-corrosion conductive paint or asphalt paint should be applied.
Chemically stable non-metallic conductor materials are used as the conductive medium of the module, and its conductivity is not affected by seasons.
The filling soil should be sprinkled with appropriate amounts of water, compacted in layers, and the grounding resistance should be measured after the module has fully absorbed moisture
(
hours
)
. It can absorb moisture and moisturize, maintain effective contact with soil, and has low grounding resistance. Exothermic flux is corrosion-resistant, non-toxic, has a long service life and is easy to install. Exothermic flux
The grounding module contains stable conductive components, metal passivation preservatives, water-retaining agents and other components. By burying it underground, it can be in close contact with the soil, expand the cross-sectional area of dispersion, and form a low-resistance area with gentle resistivity changes underground. The exothermic flux can significantly reduce the grounding resistance of the entire ground network.
