Description
Technical field
The invention belongs to steel material surface plating technic technical field, the more particularly to long-life for heavy corrosion environment
Aerial earth wire and its coating.
Background technology
Corrosion is the result acted in steel material and surrounding medium in phase interfacial reaction, it is estimated that the whole world is every year because of corruption
Lose the steel scrapped and account for the 30% of annual output, the steel produced every year about 10% goes completely into waste.
Conventional overhead ground wire plating zinc protective layer is influenced be subject to natural environment deterioration and transmission line of electricity electromagnetic environment, corrosion speed
Rate is accelerated increasingly, substantially reduces its service life, and (such as coastal area, Acid Rain Area, industry are dirty in heavy corrosion ambient environment
Contaminate area etc.), obvious corrosion occurs after general 5~8 years, its service life was less than 10 years, it has to carries out integral replacing, increases greatly
Add maintenance cost, reduce electric network security.Especially in the electromagnetic field environment such as highfield, lightning stroke, galvanomagnetic-effect can add
The corrosion of acute coating.Aerial earth wire possesses more excellent corrosion resistance using zinc-aluminum-magnesium rare earth protective coating than pure zinc protective coating
Can, become current research hotspot.In commercial process, aluminium, magnesium, rare earth and aerial earth wire base steel precursor reactant require height,
Not only influence whether the surface quality of protective layer, but also protective layer adhesiveness can be caused to decline to cause plating leakage.Therefore need to study
The new Anticorrosion measure of aerial earth wire under the electromagnetic field environment such as lightning stroke, highfield.
