Description
Technical field
Earthing material anticorrosion connection method, category power ground aseptic technic neck are combined the present invention relates to a kind of soft graphite
Domain.
Background technology
For a long time, domestic and international Ground Network of Transmission Line with Renovation generally uses the metal class earthing materials such as band steel, stainless steel, copper,
And galvanized steel, stainless steel Baogang, copper covered steel metallic ground material containing electroplated metal layer, except transport and difficulty of construction are big, easy
Beyond generation steal phenomenon, the maximum bottleneck problem of metallic ground material is the corrosion of earthing material.
Soft graphite is combined earthing material, and there is acid-alkali-corrosive-resisting, non-corrosive, heavy current impact not to strike back, grounding resistance is steady
It is fixed, water-fast, high-low temperature resistant, the advantages of service life is long, connection is without electrically welding, and light weight is easy to construct and transported, therefore
Soft graphite is combined earthing material and increasingly paid attention to by engineers and technicians.However, in actual applications, soft graphite
Compound earthing material often needs segmentation to connect or need to be connected with metal material, in junction it occur frequently that serious corrosion, leads
Resistance rise even open circuit is sent a telegraph, so as to seriously limit application of the Flexible Graphite Composites in ground connection field.
The compound earthing material connection of soft graphite uses added metal sleeve pipe and crimped.It is soft under natural environment
Property graphite and metal occur galvanic corrosion, graphite is used as anode as negative electrode, metal.When galvanic corrosion occurs, metal erosion speed
Corrosion rate when rate is than metal individualism is much faster.In addition, its surface area is much larger than anode as the soft graphite of negative electrode
Metal surface area, anode and cathode area is than bigger, and galvanic corrosion is more serious.
The content of the invention
The purpose of the present invention is that being combined earthing material there is provided a kind of soft graphite for the defect that prior art is present prevents
Rotten connection method, can effectively suppress the corrosion between graphite earthing material and metal, exist so as to solve Flexible Graphite Composites
It is grounded the bottleneck problem of application aspect.
Technical scheme:
The present invention coupling part of soft graphite and metal is positioned in hollow mould, fluid sealant by mould above
Inlet is injected into mould cavity, and is solidified, after the demoulding, and the coupling part of soft graphite and metal is closely wrapped by fluid sealant
Envelope, isolates, antiseptic effect is notable so as to realize with external environment condition.
The principle of the present invention is that corrosion occurs under environmental attack, if can isolate erosion environment, corrosion will not
Can occur;The junction of soft graphite and metal is coated by encapsulating using fluid sealant, so as to isolate the corruption such as water, gas, soil
Environment is lost, etch-proof purpose is reached.
The hollow mould of the inventive method, is made up of, two parts hollow mould top half and hollow mould the latter half
Complete hollow mould is constituted after merging, and forms mould inside cavity, wherein hollow mould top half has fluid sealant injection
Mouthful, fluid sealant inlet is connected with mould inside cavity.
The coupling part of soft graphite and metal in the inventive method, refers specifically to metal connecting piece and soft graphite is combined and connect
The part of ground material connection.Soft graphite connection uses added metal sleeve pipe and crimped, and galvanic corrosion is notable herein.
Fluid sealant in the inventive method, refers to anti-corrosion fluid sealant, it is unsaturated poly- that the present invention provides two kinds of batch preparations of A, B
The method of ester fluid sealant is so as to the implementation of the present invention, and wherein A fluid sealants are with 307#(Or 306#)Unsaturated polyester (UP) and 182# are not
Saturated polyester is major ingredient, is produced by auxiliary material of reinforcing agent, initiator and accelerator, and B fluid sealants are poly- to be modified 191# unsaturations
Ester resin is major ingredient, is produced using initiator and accelerator as auxiliary material.

Embodiment
The present invention is described in further detail with reference to embodiment.
Hollow mould in the present embodiment is made up of hollow mould top half 1 and hollow mould the latter half 2, two parts
Complete hollow mould is constituted after merging, and forms mould inside cavity 7, wherein hollow mould top half 1 has fluid sealant note
Entrance 3, fluid sealant inlet 3 is connected with mould inside cavity 7.The coupling part of soft graphite and metal, refers specifically to metal company
Fitting 5 and soft graphite are combined the part that earthing material 6 is connected.Soft graphite connection uses added metal sleeve pipe and pressed
Connect, galvanic corrosion is notable herein.
In present embodiment, fluid sealant compounding method is as follows:
