Abstract

A composite anti-corrosion grounding body of a ground network belongs to the field of ground network anti-corrosion technique. The composite anti-corrosion grounding body of the ground network is characterized in that an iron plate or a galvanized iron plate has a rough surface; and a dry nanometer carbon anti-corrosion conductive coating layer is applied to the surface of the rough iron plate or the galvanized iron plate. The positive effect of the grounding body is that the anti-corrosion conductive coating layer on the surface of the iron plate or the galvanized iron plate is selected from a JR nanometer carbon anti-corrosion conductive coating of the patent ZL03125237.0, so that the nanometer conductive material and a film forming material can permeate each other by a particle diameter of almost the same order of magnitude and no apparent interface exists between the two materials. Accordingly, the nanometer coating has good close function to prevent the electrolyte solution from permeating the coating, so that the anti-corrosion property of the nanometer carbon anti-corrosion conductive coating is better than that of the common coating. The JR nanometer carbon anti-corrosion coating has the thermal stability of 30 KA/2 S. Once the ground network encounters the large-current impact caused by lightning or short-circuit accidents, the JR nanometer carbon anti-corrosion conductive coating can not be burned out.

Description

A kind of earth mat earth electrode of composite anti-corrosive

Technical field

Possession net ground connection, corrosion protection technology field exactly relate to the earth mat aseptic technic.

Background technology

Present commonplace employing hot dip galvanizing process protection earth mat.Because the electrode potential of zinc is lower than iron, in the corrosion galvanic cell that iron and zinc constitute, zinc as anode loss protection earth mat.But the thickness of zinc coat is limited, thereby the earth mat protection time limit is very short.As make the ground net materials with copper material? can cause the heavy metal pollution of soil source.The content of some heavy metal substance has surpassed the self-purification capacity of soil in soil, and is absorbed by the body by " soil → plant → human body " or " soil → water → human body ", be detrimental to health, and be exactly heavy metal pollution of soil.Along with the development of material progress, increasing heavy metal discarded object and the waste water that contains heavy metal have caused heavy metal pollution of soil constantly to soil permeability.The cupric discarded object that human civilization is brought has made that Cu Pollution in Soil grows with each passing day, and it is extremely fragile that soil environment quality becomes.We will fully realize the cumulative bad and the intractable of Cu Pollution in Soil, the pollutant sources of strict control copper.China power plant, transformer station spread all over the place, if we directly with tens so that up to a hundred tons of copper materials imbed in 1 meter dark soil of less than and do earth mat, the source of heavy metal pollution that this is maximum in the world, land resources will be by pollution in wide area! The soil environment quality problem is related to the strategic big problem of sustainable economic development, and it directly influences the yield and quality of agricultural product, and influences human health by food chain.In recent years, there are many copper covered steels, copper facing product to release one after another both at home and abroad.There are the potential difference between copper and the steel in this copper covered steel or copper-plated material.Under the slowly drained soil condition, its electrochemical corrosion is quite surprising.Common mechanical workman knows: twisting a brass screw on the steel plate or on copper coin, twisting a steel screw, under wet condition, differ week screw just rust is in the dust.In case so copper covered steel or the corrosion of copper facing earth mat origination point, earth mat is easy to corrosion fracture.As using graphite conducting coating material in the earth mat, because of graphite is carbon, press the material that the SP2 hybridized orbit constitutes, have layer structure and conductivity.The electrically-conducting paint made from graphite conducts electricity very well, but antiseptic property is bad.The layer structure of graphite has determined that the coating closure is poor.The stress that this coating produces in the dry solidification process makes the graphite layers cracking, and electrolyte solution is just taken advantage of a weak point.And the electrode potential of carbon is than iron height, and in the corrosion galvanic cell that conductive coating and earth mat carbon steel constitute, carbon steel has been accelerated the earth mat corrosion as sacrificial anode.So graphite conducting coating material can be accelerated the earth mat corrosion.

Summary of the invention

The utility model is that its protection time limit of earth mat that will provide is not short, and antiseptic property is good, and soil is avoided heavy metal pollution, meets a kind of composite anti-corrosive earth mat earth electrode of environmental protection requirement.

The technical scheme that the utility model is taked:

A kind of earth mat earth electrode of composite anti-corrosive, comprising by iron plate or galvanized iron sheet is the earth electrode that substrate constitutes, its scheme is: iron plate or galvanized iron sheet have rough surface, dry nano-carbon anticorrosion conductive coating layer on coarse iron plate or galvanized iron sheet surface coverage.

Good effect behind enforcement the utility model is:

Owing to cover the corrosion-resistant conductive coating layer on iron plate or galvanized iron sheet surface, it is to adopt the patent No. to be: the patent of invention product J R nano-carbon anticorrosion conductive coating of ZL03125237.0, nanometer conductive material and filmogen interpenetrate with the particle diameter of the same order of magnitude almost, there is not tangible interface each other, the nano paint closing function is good, electrolyte solution can't be penetrated into coating inside, so the anti-corrosive properties of nano-carbon anticorrosion conductive coating are better than general anticorrosion with coat.And the JR nano-carbon anticorrosion conductive coating has the thermal stability of 30KA/2S.In case when earth mat suffered the heavy current impact of thunder and lightning or short circuit accident formation, the JR nano-carbon anticorrosion conductive coating can not burnt.
