Any one in propylene or propine.
Using the corrosion resistance and super-hydrophobicity of Graphene, water, corrosive ion etc. is hindered to suspend the infiltration of line in midair to high ferro,
Prevent from high ferro from suspending line in midair to be oxidized or be corroded, and then high ferro suspention line is played a protective role, extension high ferro suspends making for line in midair
Use the life-span.
The invention provides a kind of application of Graphene, compared to prior art, have the advantages that：
1st, the present invention is simple to operate, with low cost, in can be applied to industrialized production.Because Graphene has corrosion resistance
And super-hydrophobicity, corrodibility ion and the water in external environment can be effectively resisted, antiseptic effect is obvious.
2nd, the conductive good, light weight of Graphene, it is moisture resistance, environmentally friendly the advantages of, and to high ferro suspention line intensity will not produce
Raw influence, it can be ensured that the normal use of high ferro suspention line.
3rd, the stickiness of Graphene and high ferro suspention line is good, under the extreme weather conditions such as high temperature, heavy rain, arid, when long
Between use, Graphene will not also come off from high ferro suspention line surface.
